Contrary to the dominant arguments put forth by Black feminist scholars, this essay argues that W.E.B. Du Bois’ pioneering role in establishing the principles of Black sociology, ethnological arguments and long-range development of Pan-Africanism as an ideological rival to colonial imperialism/Westernism suggests that the masculine roots informing his approach to the Black intellectual endeavor is a positive and humanistic rather than a restrictive marker of his thought. If Du Bois’ masculinization of Black agency and intellectual endeavors were simply indicative of (...) mimesis – his internalization of the very sexism against which he fought anchored to a view of freedom for Black people which materialized as a struggle among men over the control of the bodies of Black women – then there should be textual evidence demonstrating that he (like some of his Black female peers) supported the relegation of Black women to domesticity or was in favor of US imperialism against darker races abroad. But rather than an imitative aspiration towards Black nationalist patriarchy and the subordination of Black women to men’s will, the logical consequence of Du Bois’ masculinist (ethnological) thinking as it relates to the Black intellectual endeavor and the problem of race in America materialized as the formulation of Black sociology to study Black men and women as agents of history who were endowed with unique insights stemming from their experiences of marginalization, his articulation of an anti-colonial and egalitarian Black manhood, and his laying an intellectual basis for Pan-Africanism to emerge as an anti-colonial ideology.

This treatise conducts a systematic dependency analysis of Jungian psychology following the demonstration that Jung’s collective unconscious hypothesis lacks empirical warrant as a mechanism of phylogenetic psychic inheritance (Boether, 2025a). Adopting the philosophy of science framework developed by Lakatos (1978), I treat the collective unconscious as the “hard core” of Jung’s research programme and trace the propagation of its failure through the “protective belt” of derivative constructs: archetypes, individuation, synchronicity, active imagination, dream interpretation, and psychological types. The analysis distinguishes four (...) tiers of theoretical vulnerability: constructs that collapse without the collective unconscious, those substantially weakened, those indirectly affected, and those that survive independently. Drawing upon the Life-Experience Encyclopedia model and the Pyramid of Personality framework (Boether, 2025a), supplemented by attachment theory (Bowlby, 1969/1982) and predictive processing (Clark, 2016), I demonstrate that the phenomenological observations motivating Jung’s original theorizing can be preserved through developmental convergence—the thesis that universal psychic patterns arise from shared constraints of early human development rather than inherited psychic structures. The result is a reconstruction agenda that salvages what is empirically defensible in Jungian thought while excising its metaphysical excesses. (shrink)

This research was done in Juiz de Fora, Minas Gerais, Brazil on february 2012, with objective was to determine which species of social wasps visiting mango fruits, their behaviors displayed by them while foraging and verify which the species of wasps visitors offer risk of accidents to farmers. The studied area was monitored during February 2012, from 8:00 to 17:00. in a 144 hour effort, and the data collected included the time of activity, diversity, aggressiveness and the general behavior of (...) social wasps around the fruits. There were registered a total of 175 individuals of 12 different species, healthy fruits were damaged during the day, and we registered the abundance and richness peaks throughout the day. This study indicated the needs for special care during the harvest, as aggressive wasps are indeed present and the abundant, resulting in a possible increase of the risk for the workers. (shrink)

René Descartes envisioned morals as the highest fruit of his philosophical system—the uppermost branch of his famous tree of philosophy—yet died in 1650 before completing the systematic moral psychology his framework demanded. The Passions of the Soul (1649), though groundbreaking in its mechanistic treatment of the six primitive passions and its articulation of générosité as the master virtue, left unresolved at least five critical lacunae: the integration of philosophical and psychological function within the mind-body union, a developmental account of (...) how the cogito matures across the lifespan, a positive definition of the sound mind beyond pathological absence, substantive moral criteria beyond the directive to “use reason,” and a personality architecture adequate to the complexity of human passional life. This treatise identifies these gaps through careful analysis of Descartes’ published works, correspondence with Princess Elisabeth of Bohemia, and the secondary literature, then proposes a good-faith philosophical completion drawing upon three frameworks from the author’s theoretical corpus: the Double Helix of Understanding (Boether, 2025a), the Mathematics of the “I” (Boether, 2025b), and the Sound Mind reconstruction (Boether, 2026). The paper maintains explicit delineation between Descartes’ original positions and the proposed extensions, presenting each gap alongside its corresponding completion in an interleaved dialectical structure. The argument proceeds that these contemporary frameworks, while developed independently, operate within the Cartesian architectural logic of grounding practical wisdom in foundational knowledge of mind, body, and their union.

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of this paper (...) is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the (...) nineteenth century, there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

Lorenzo Magnani’s Understanding Violence: The Intertwining of Morality, Religion and Violence is a big 23 book. Not big in the sense of page count or prepublication advertisement, but big in the sense of pregnant 24 with potential application. Professor Magnani is explicit in his intentions, “to show how violence is de facto 25 intertwined with morality, and how much violence is hidden, and invisibly or unintentionally performed" 26 (page 273) while confessing a personal motivation, “warning myself (and every reader) that (...) violence is 27 traceable back to my (our) own door.” (page 66) This is not an easy task, given the slippery expanse of his 28 subject, to drag violence out of the shadows, bringing it home to each personal purveyor. But Magnani 29 succeeds, and fruitfully. Understanding Violence deftly exposes violence in its myriad forms from individual 30 aggression to colliding global-historical narratives. It does this by detailing the processes whereby people act 31 from moralities of their own creation, adopting various moral frameworks including those specific to 32 religions, social and political groups, as well as personal constructs, and in terms of which "they engage and 33 disengage both intentionally and unintentionally, in a strict interplay between morality and violence." (page 34 184) Resolving these complex dynamics through simple models and illustrations, Understanding Violence 35 elevates the reader from the forest-for-the-trees perpetual-crisis-blindness symptomatic of the present era, to 36 a position from which personal moral commitments as practical, as necessary, and as the source of hidden 37 violence are clearly visible. Moreover, due to the practicality of Magnani’s demonstrations, it continues in 38 this work long after the text itself is laid back on the shelf. (shrink)

................English....................... The purpose of this study is to reveal university students’ perceptions regarding Holy Qur’an through metaphors. The survey group of study consists of 194 participants who were studying in Theology Department and Social Service Department at Gümüşhane University in the 2014-2015 academic terms. Both quantitative and qualitative methods are used together. The study’s data was collected through a form with the phrase “The Holy Qur’an is similar/like…, because...” and some demographical variables. The Content Analysis Technique was used to interpret (...) data. Results of this study determined that 44 different metaphors regarding Holy Qur’an were given by participants. Theme of these metaphors were compiled as 9 categories consisting of directional, life source, explanatory, key, protective, curative, instructive, speech, and other categories. Top metaphors are in the directional, life source and explanatory categories. Key words are metaphor, perception, The Qur’an perception, religious concepts, and religious symbols. Getting data through comprehensive and in-dept analysis can help to have information about concepts of holy books in the human mind. The purpose of this study is to pick out perceptions of university students with regard to the Holy Qur’an through metaphors. For this reason, these questions are searched by researchers: 1) What are the metaphors which used by university students on description of perceptions regarding the Holy Qur’an? 2) How are the metaphors regarding the Holy Qur’an categorized in terms of common characteristics which produced by university students? 3) Are there any links between socio-demographic variables and composed metaphoric categories? One of the qualitative data collection technics, data collecting through metaphors method is used, and is asked open-ended question in the study. Picking up similarities and diversities under thematic topics is quite easy in the method. Therefore, this method has a functional feature in the sociology, psychology and anthropology, and it gives a wealthy and qualified image about matter, phenomenon, event and situation (Yıldırım & Şimşek 2005, 212). The target population of the study consists of students who were taking education at Gümüşhane University. Easily accessible and availability principles pursued in the sample choosing. In the distribution of participants according to the demographical features, females have 61.9 percent (n:120) and males have 38.1 percent (n:74) in terms of gender. Students who graduated from religious vocational high school is 61.3 percent (n:119), and others who from other high schools is 38.7 percent (n:75) in terms of graduated from different high schools. Students in theology department have 68.0 percent (n:132), and students who were educated in the social service department have 32.0 percent (n:62). Research data is gathered through survey form includes “The Holy Qur’an is like/similar to…, because…” sentence and demographical variabilities. Data, gathered from 194 survey forms, is transferred to the Excel and the SPSS program. In an attempt to reliability of study, gathered metaphors is examined by four area expert. Frequencies (f) and percentages (%) is taken into consideration in the process of replacing metaphors to the tables. Data analysis technique is used on the getting relationships and explaining gathered data, while content analysis technique is used on the interpreting of data. The SPSS program is used in the analysis of quantitative data. Obtained data from the surveys and composed categories is associated with descriptive statements in the verses of the Holy Qur’an. In the composed categories demonstrate distribution of produced 44 different metaphors with regard to the Holy Qur’an as 9 categories. According to this, the sample is represented in the categories as 64.4 % (f:125) is in the ‘directional’, 11.3 % (f:22) is in the ‘life source’, 7.7 % (f:15) is in the ‘explanatory’, 3.1 % (f:6) is in the ‘key’, 3.1 % (f:6) is in the ‘protective’, 2.1 % (f:4) is in the ‘curative’, 2.1 % (f:4) is in the ‘instructive’, 2.1 % (f:4) is in the ‘speech’ and 4.1 % (f:8) is in the ‘other’ categories. Distributions of composed categories are represented according to common characteristics as frequencies and percentages in the next tables. In the distribution of produced metaphors in the ‘directional’ category, university students produced 7 different metaphors (f:125). Frequencies of produced metaphors in the category are such that: guide (f:41), advisor (f:25), mentor (f:19), compass (f:16), road map (f:8), route (f:3) and other (f:13). According to the result, it is understood that aspects of guide, advisor, mentor and compass stood mostly out in the category. In the ‘life source’ category, 6 different metaphors (f:22) is developed by participants. Developed metaphors’ frequencies in the category are the following: life (f:4), lifeblood (f:4), weather (f:2), water (f:2), inheritance (f:2) and others (f:7). So, life and lifeblood aspects stood mostly out in the category. In the ‘explanatory’ category, 5 different metaphor (f:15) is developed by participants. Frequencies of produced metaphors in the category are such that: light (f:5), sun (f:3), flashlight (f:2), torch (f:2) and other (f:3). According to the result, it is understood that aspects of light and sun stood mostly out in the category In the ‘protective’ category, 5 different metaphors (f:6) is developed by participants. Frequencies of produced metaphors in the category are such that: saver (f:2), lifeguard (f:1), hereafter-saving (f:1), escapeway (f:1) and branch to catch (f:1). According to the result, it is understood that aspect of saver stood mostly out in the category. In the ‘instructive’ category, 4 different metaphors (f:6) is developed by participants. Frequencies of produced metaphors in the category are such that: reference book (f:1), dictionary (f:1), priceless book (f:1) and life encyclopedia (f:1). In the ‘speech’ category, it is seen that 4 different metaphors (f:6) is developed by participants. Frequencies of produced metaphors in the category are such that: divine message (f:1), speaking truth (f:1), Allah’s dialogue with us (f:1) and final word (f:1). In the ‘key’ category, 3 different metaphors (f:6) is developed by participants. Frequencies of produced metaphors in the category are such that: a key (f:4), the key of heaven (f:1) and the key of salvation (f:1). In the ‘curative’ category, 2 different metaphors (f:4) is developed by participants. Frequencies of produced metaphors in the category are such that: a pill (f:3) and doctor (f:1). In the ‘others’ category, 8 different metaphors (f:8) is developed by participants. Frequencies of produced metaphors in the category are such that: world (f:1), the friend of lonely passenger (f:1), the tree with fruit (f:1), hereafter (f:1), priceless treasure (f:1), miracle (f:1), philosophy (f:1) and mirror (f:1). Participants composed of 44 different metaphors regarding the Holy Qur’an. The metaphors were summed up in the 9 categories as ‘directional’, ‘life source’, ‘explanatory’, ‘key’, ‘protective’, ‘curative’, ‘instructive’, ‘speech’ and ‘other’ To results of the study; guide, advisor, mentor and compass aspects of the Qur’an came into prominence at most in the ‘directional’ category, when life and lifeblood aspects of the Qur’an came into prominence at most in the ‘life source’ category. Light and sunny aspects of the Qur’an came into prominence at most in the ‘explanatory’ category, while saver aspect of the Qur’an came into prominence at most in the ‘protective’ category. Instructive aspect of the Qur’an came into prominence at most in the ‘instructive’ category. Speech aspect of the Qur’an came into prominence at most in the ‘speech’ category, while key aspect of the Qur’an came into prominence at most in the ‘key’ category. Moreover, pill aspect of the Qur’an came into prominence at most in the ‘curative’ category. Whatsoever world, friend of single traveler, tree with fruit, hereafter, priceless treasure, miracle, philosophy and mirror aspects of the Qur’an came into prominence at most in the ‘other’ category. It is inferred that significant relationships between demographic variables and metaphor categories. In terms of major variable; theology students were composed of more metaphor in the ‘explanatory’ and ‘instructive’ categories, while social service students were composed of more metaphor in the ‘life source’ category. In terms of gender variable; females composed of more metaphor in the ‘curative’ and ‘other’ categories, while males composed of more metaphor in the ‘directional category. In terms of graduating high school variable, students who graduated from religious vocational high school composed of more metaphor in the ‘key’ and ‘speech’ categories, when students who graduated from other high school composed of more metaphor in the ‘directional’ category. Whatsoever, in terms of having the Qur’an education in their life status variable, had the Qur’an education in their life students composed of more metaphor in the ‘curative’ and ‘other’ categories, while other group composed of more metaphor in the ‘directional’. Moreover, in terms of perception of subjective religiousness, students who think themselves are ‘religious’ composed of more metaphor in the ‘key’ and ‘other’ categories, while students who think themselves are ‘less religious’ composed of more metaphor in the ‘explanatory’ category. In terms of perception of family religiousness, students who think own family ‘less religious’ composed of more metaphor in the ‘directional’ and ‘life source’ categories, when students who think own family ‘religious’ composed of more metaphor in the ‘key’ category. It can be suggested by the results of this study; perception of the Qur’an can be studied with the different study techniques, or it can be studied in the different research groups with the same technique. Muslims’ perceptions regarding the Holy Qur’an can be examined with intercultural comparative studies. Perceptions regarding the Holy Qur’an can be researched through interviews. Members’ perception regarding holy book that have different religious faith can be comparatively examined. Individuals’ perceptions regarding different religious concepts can be studied through metaphors................... Turkish...................Bu araştırmanın amacı üniversite öğrencilerinin Kur’an-ı Kerim’e ilişkin algılarını metaforlar aracılığıyla ortaya çıkarmaktır. Araştırmanın çalışma grubunu, 2014-2015 eğitim öğretim yılında Gümüşhane Üniversitesi İlahiyat Fakültesi ve Sosyal Hizmetler bölümünde öğrenim gören 194 katılımcı oluşturmaktadır. Araştırmada nitel ve nicel yöntemler birlikte kullanılmıştır. Araştırma verileri, “Kur’an-ı Kerim……gibidir, çünkü……” cümlesini ve demografik değişkenleri içeren bir form aracılığıyla toplanmıştır.

Bu metaforlardan ‘yönlendirici’, ‘yaşam kaynağı’, ‘açıklayıcı’, ‘anahtar’, ‘koruyucu’, ‘öğretici’, ‘derman’, ‘kelam’ ve ‘diğer’ olmak üzere 9 farklı kategori oluşturulmuştur. Üretilen metaforların ‘yönlendirici’, ‘yaşam kaynağı’ ve ‘açıklayıcı’ kategorilerinde yoğunlaştığı görülmüştür. Demografik değişkenler ile metafor kategorileri arasındaki ilişkiyi ortaya çıkarmak araştırmanın ikincil amaçlarındandır ve bu yönüyle sonuçlar değerlendirildiğinde değişkenler ile kategoriler arasında anlamlı ilişkiler olduğu tespit edilmiştir. Demografik değişkenler ile kategori ilişkisinde fakülte değişkeni açısından ilahiyat öğrencileri ‘açıklayıcı’ ve ‘öğretici’ kategorilerinde daha fazla metafor üretirken sosyal hizmet öğrencileri ‘yaşam kaynağı’ kategorisinde daha fazla metafor üretmiştir. Cinsiyet değişkeni açısından ise kız öğrenciler ‘derman’ ve ‘diğer’ kategorilerinde daha fazla metafor üretirken erkek öğrenciler ‘yönlendirici’ kategorisinde daha fazla metafor üretmiştir. Lise mezuniyeti açısından bakıldığında da İHL’den mezun olanlar ‘anahtar’ ve ‘kelam’ kategorilerinde daha fazla metafor üretirken diğer lise mezunları ‘yönlendirici’ kategorisinde daha fazla metafor üretmiştir. Kur’an Kursu eğitimi alma değişkeni açısından ise Kur’an kursu eğitimi alanlar ‘derman’ ve ‘diğer’ kategorilerinde daha fazla metafor üretirken Kur’an Kursu eğitimi almayanlar ‘yönlendirici’ kategorisinde daha fazla metafor üretmiştir. Ayrıca öznel dindarlık ve aile dindarlık algılarıyla metafor kategorileri arasında da anlamlı ilişkiler elde edilmiştir. (shrink)

Descartes is not well known for his contributions to ethics. Some have charged that it is a weakness of his philosophy that it focuses exclusively on metaphysics and epistemology to the exclusion of moral and political philosophy. Such criticisms rest on a misunderstanding of the broader framework of Descartes’ philosophy. Evidence of Descartes’ concern for the practical import of philosophy can be traced to his earliest writings. In agreement of wisdom that is sufficient for happiness. The Third part of his (...) Discourse on the Method presents what he calls a provisional morality, a morality to govern our behaviour while we are in the process of revising our beliefs and coming to certainty. In the tree of philosophy, in the Preface to the French translation of the Principles of Philosophy, morals are listed as one of the fruits of the tree, along with medicine and mechanics. It is also a theme in the letters he exchanged with the Princess Elisabeth of Bohemia in the mid-1640s, together with another concern the passions, what they are, and more importantly, how to control them. These themes are intertwined again in Descartes last major work, The Passions of the Soul (1649). Descartes did not write extensively on ethics, and this has led some to assume that the topic lacks a place within his philosophy. It is an attempt to outline Descartes’ ethical ideas mainly in Discourse on the Method. (shrink)

Noa Naaman-Zauderer’s book aims to bring to light the ethical underpinnings of Descartes’ system: on her view, in both the practical and the theoretical spheres Descartes takes our foremost duty to lie in the good use of the will.The marked ethical import of Cartesian epistemology takes the form of a deontological, non-consequentialist view of error: epistemic agents are praised/blamed when they fulfill/flout the duty to not assent to ideas that are less than clear and distinct.Extra-theoretical realms admitting of no clear (...) and distinct perceptions are subject to ‘softer’ duties of acting on the basis of the best available reasons. Since Cartesian epistemology involves ethical considerations,and since the late Cartesian ethics of virtue crucially depends on metaphysical knowledge about the nature and function of the will, Descartes’ ethics is not just a fruit of his tree of knowledge but it also nourishes its own roots.

The empirical and theoretical resources of different disciplines are often combined to shed light on questions that concern the deep history of humanity, such as the geographic origin of people groups, patterns of migration, and the diffusion of culture. In this article, I discuss three ways in which other disciplines, such as biology and archaeology, are integrated with historical linguistics to enhance our understanding of the past. First, other disciplines provide background knowledge that helps to constrain and assess competing historical (...) explanations of the data. I examine this issue in the context of the Principle of the Common Cause and Inference to the Best Explanation. Second, the synthesis of data from multiple disciplines provides a diverse and varied set of evidence, which is epistemically superior, other things being equal, to a homogeneous set of evidence. I consider several justifications for the confirmational value of diverse evidence. Finally, methods and procedures from other disciplines can often be fruitfully applied to forge new pathways to knowledge. Here, I survey the recent application of phylogenetic methods from biology, used for inferring evolutionary trees, within historical linguistics. (shrink)

The Story of Adam and Eve: A Comprehensive Analysis -/- The story of Adam and Eve is one of the most profound and influential narratives in human history. Found in the Bible (Genesis), the Qur’an, and other religious traditions, it has shaped how people understand free will, morality, knowledge, sin, and redemption. This essay explores the story’s theological, philosophical, psychological, mythological, scientific, and literary implications. -/- 1. Theological Perspectives -/- A. Judaism: The Human Moral Struggle -/- In Judaism, the story (...) appears in Genesis 2–3, but it is not seen as the source of “original sin.” Instead, it represents the human struggle between good and evil inclinations. The serpent is not necessarily Satan but a symbol of temptation and human desires. Adam and Eve’s exile from Eden is interpreted as humanity’s transition to responsibility rather than an eternal punishment. -/- B. Christianity: Original Sin and Redemption -/- Christianity, particularly in Augustinian theology, views Adam and Eve’s sin as the cause of original sin, which is inherited by all humanity. The serpent is identified as Satan (Revelation 12:9), deceiving mankind. Jesus Christ is considered the “New Adam,” bringing salvation to humanity (Romans 5:12-21). The story lays the foundation for Christian doctrines of sin, salvation, and divine grace. -/- C. Islam: A Test, Not a Fall -/- In Islam, the story appears in the Qur’an (Surahs 2:30-39, 7:11-25, 20:115-124). Here, Satan (Iblis), not the serpent, tempts Adam and Eve. However, unlike Christianity, Adam and Eve repent, and Allah forgives them, emphasizing that humans are not doomed by original sin but are responsible for their own choices. Their descent to Earth is seen as a divine test rather than a punishment. -/- 2. Philosophical Perspectives -/- A. Free Will and Moral Responsibility -/- The story raises fundamental philosophical questions: Did Adam and Eve truly have free will? If God knew they would disobey, was their choice real, or was it predetermined? This aligns with compatibilism, the idea that free will exists within divine or natural laws. -/- B. The Nature of Good and Evil -/- The Tree of Knowledge of Good and Evil symbolizes moral awareness. Was eating the fruit an act of rebellion or enlightenment? Søren Kierkegaard interpreted the story as an example of “anxiety”—the moment humans became aware of moral responsibility. -/- C. Existentialist Interpretation -/- For existentialists like Jean-Paul Sartre, Adam and Eve’s exile from Eden represents alienation, a central theme in existentialism. Their story mirrors the human search for meaning after gaining self-awareness. -/- 3. Psychological Perspectives -/- A. The Transition from Innocence to Awareness -/- The story mirrors human development from childhood innocence to adulthood self-awareness. Sigmund Freud saw the forbidden fruit as a metaphor for repressed desires—with the serpent representing instincts and God’s law representing moral conscience. Carl Jung interpreted the story as an example of individuation, the process of integrating all aspects of the self. -/- B. Guilt and Shame -/- Before eating the fruit, Adam and Eve were unashamed of their nakedness—symbolizing innocence. After eating, they experienced guilt and shame, reflecting how humans develop a moral conscience. -/- 4. Mythological and Cross-Cultural Comparisons -/- Many creation myths explore similar themes: -/- 5. Scientific and Evolutionary Interpretations -/- A. Anthropological View -/- The story might symbolize the emergence of early human consciousness, when humans first developed self-awareness and moral codes. -/- B. Neuroscientific View -/- Modern neuroscience suggests that the shift from instinct-driven behavior to rational moral reasoning mirrors the brain’s evolution. The story represents the emergence of the prefrontal cortex, responsible for decision-making and morality. -/- 6. Literary and Symbolic Interpretations -/- A. Eden as a Utopia -/- The Garden of Eden represents a perfect world that humans lost due to their choices. -/- B. The Serpent as Knowledge -/- Some interpretations suggest the serpent is a bringer of enlightenment, not just a deceiver. -/- C. The Banishment as Transformation -/- Leaving Eden is not merely exile but a necessary step in human progress—the beginning of human civilization. -/- 7. Conclusion: The Universal Meaning of Adam and Eve -/- The story of Adam and Eve transcends religious traditions, offering insights into human nature, morality, and free will. -/- Religiously, it teaches about obedience, sin, and redemption. -/- Philosophically, it raises questions about free will, knowledge, and morality. -/- Psychologically, it represents human development and self-awareness. -/- Mythologically, it connects to ancient themes of knowledge and consequence. -/- Scientifically, it mirrors human evolution and moral consciousness. -/- Literarily, it serves as a metaphor for humanity’s transition from innocence to wisdom. -/- Ultimately, the story of Adam and Eve is not just about the past—it continues to shape the way we think about the present and the future. -/- .

We study the first-order theories of some natural and important classes of coloured trees, including the four classes of trees whose paths have the order type respectively of the natural numbers, the integers, the rationals, and the reals. We develop a technique for approximating a tree as a suitably coloured linear order. We then present the first-order theories of certain classes of coloured linear orders and use them, along with the approximating technique, to establish complete axiomatisations of the (...) four classes of trees mentioned above.

This paper presents a minimal tree-based framework for verifying object isomorphism in arbitrary categories using Minimum Spanning Trees (MSTs) over a fixed set of probes. The system is strictly weaker than $RCA_0$, avoiding numeric or comprehension axioms. By leveraging MST traversal, it ensures the minimal set of Hom-set comparisons for isomorphism verification. The framework extends to structured formula verification via Abstract Syntax Trees (ASTs). Explicit weight functions, rigorous proofs, and concrete examples ensure mathematical correctness and reproducibility.

The philosophical riddle ‘If a tree falls in a forest and no one is there to hear it, does it make a sound?’ dramatises a conflict that is not merely metaphysical but epistemic and political. This essay reframes the question through Epistemic Clientelism Theory, showing how assent to either physics or phenomenology constitutes a clientelist exchange with epistemic authority. Drawing on Locke, Berkeley, and Kant, alongside phenomenology, cognitive science, and political psychology, I argue that the puzzle exposes our dependence on (...) authority structures. Silence is shown not as absence but as epistemic subjugation, resonant with Spivak’s notion of epistemic violence. Engaging Ivana Marková’s theory of epistemic trust and my own works on epistemocracy, free-range knowledge, and fiduciary openness, I propose that dependence need not degrade into clientelism. Fiduciary authority offers a way forward, binding epistemic power to duties of care, loyalty, and openness. The falling tree thus becomes a parable for our epistemic condition: vibrations exist, perception matters, but what counts as ‘sound’ depends on how authority is structured and how silence is dignified.

Our aim here is to lay the groundwork for formal tree-ring analysis combining data from dendrochronology with formal techniques from semantics. We will present the basic syntax of, and basic compositional semantics of tree-ring structures.

Given a class of linear order types C, we identify and study several different classes of trees, naturally associated with C in terms of how the paths in those trees are related to the order types belonging to C. We investigate and completely determine the set-theoretic relationships between these classes of trees and between their corresponding first-order theories. We then obtain some general results about the axiomatization of the first-order theories of some of these classes of (...) class='Hi'>trees in terms of the first-order theory of the generating class C, and indicate the problems obstructing such general results for the other classes. These problems arise from the possible existence of nondefinable paths in trees, that need not satisfy the first-order theory of C, so we have started analysing first order definable and undefinable paths in trees.

The Tree of Life has traditionally been understood to represent the history of species lineages. However, recently researchers have suggested that it might be better interpreted as representing the history of cellular lineages, sometimes called the Tree of Cells. This paper examines and evaluates reasons offered against this cellular interpretation of the Tree of Life. It argues that some such reasons are bad reasons, based either on a false attribution of essentialism, on a misunderstanding of the problem of lineage identity, (...) or on a limited view of scientific representation. I suggest that debate about the Tree of Cells and other successors to the traditional Tree of Life should be formulated in terms of the purposes these representations may serve. In pursuing this strategy, we see that the Tree of Cells cannot serve one purpose suggested for it: as an explanation for the hierarchical nature of taxonomy. We then explore whether, instead, the tree may play an important role in the dynamic modeling of evolution. As highly-integrated complex systems, cells may influence which lineage components can successfully transfer into them and how they change once integrated. Only if they do in fact have a substantial role to play in this process might the Tree of Cells have some claim to be the Tree of Life. (shrink)

This paper will present two contributions to teaching introductory logic. The first contribution is an alternative tree proof method that differs from the traditional one-sided tree method. The second contribution combines this tree system with an index system to produce a user-friendly tree method for sentential modal logic.

The paper aims at critical reconsideration of a motif popular in Indian literary, ritual, and pictorial traditions – a tree goddess (yakṣī, vṛkṣakā) or a woman embracing a tree (śālabhañjīkā, dohada), which points to a close and intimate bond between women and trees. At the outset, I present the most important phases of the evolution of this popular motif from the ancient times to present days. Then two essential characteristics of nature recognized in Indian visual arts, literature, religions and (...) philosophy will be distinguished: (1) a dynamic, creative, self-sufficient and inexhaustible power, and (2) a passive, merely reproductive or vegetative, and dependent field of potentiality. The paper is to demonstrate the interdependence of the popular concepts of nature identified with femininity, and their iconic representations circulating for centuries in Indian culture, with a specific line of argument repeatedly used in social practices and public debates. While doing so, I consider the semiotic function of a cultural topos which proves to be an effective instrument for construing and supporting the gender roles and gender identities. As a modern example illustrating vitality and persuasive power of the motif of yakṣī and śālabhañjīkā, I refer to the Chipko Movement, a group of rural women based in the Garhwal Himalayas (state Uttarakhand), who fought against the mass cut of trees in the 1970s. They were involved in the wide-spread environmental campaign which significantly affected the ecological policy of the local and state authorities. Thus, a traditional motif of the visual arts has been revived and re-elaborated by the activists of this ecofeminist movement through converting the symbolic potential of yakṣī/śālabhañjīkā into social and political power.

We propose the Finite Tree Conjecture: that the set of syntactic trees actually realized in natural language is finite. While generative grammar presumes the infinite productivity of syntax, this assumption may have no empirical basis. The paper outlines reasons from cognitive constraint, corpus observation, and communicative pragmatics that support the plausibility of finiteness. This conjecture reframes the task of grammar: not to explain how more can be generated, but why so little ever is.

Do trees of life have roots? What do these roots look like? In this contribution, I argue that research on the origins of life might offer glimpses on the topology of these very roots. More specifically, I argue (1) that the roots of the tree of life go well below the level of the commonly mentioned ‘ancestral organisms’ down into the level of much simpler, minimally living entities that might be referred to as ‘protoliving systems’, and (2) that further (...) below, a system of roots gradually dissolves into non-living matter along several functional dimensions. In between non-living and living matter, one finds physico-chemical systems that I propose to characterize by a ‘lifeness signature’. In turn, this ‘lifeness signature’ might also account for a diverse range of biochemical entities that are found to be ‘less-than-living’ yet ‘more-than-non-living’. (shrink)

A common complaint about Kantian ethics is that it cannot do justice to the social or intersubjective dimensions of human life – that, unlike Fichte, Hegel, or Marx, Kant remains caught within a fundamentally individualistic perspective on practical or moral questions. In this way, the objection goes, Kantian ethics leaves agents alienated from others around them and their larger community. While not entirely unnatural, I argue here that such concerns rest on a mischaracterization of where the most serious problems in (...) this region for Kant lie. Far from being too individualistic, the real worry about Kantian moral theory is that it may not be individualistic enough. In a contemporary context, where Kantian ethics is associated with the “self-constitution” of agents or the “separateness of persons”, the idea that it is insufficiently concerned with individual persons may come as a surprise. But it would not surprise Kant’s immediate successors like Fichte and Hegel. For this is where they often located the deepest problems facing Kant’s moral philosophy. As we will see, in making such points, they were in some ways closer to Kant’s own views than they recognized. Nonetheless, if this is right, Kantian ethics may in fact more anti-individualistic than many of the ethical systems that followed in his wake. And the most radical elements in Kant’s ethics might point, less to Fichte and Hegel, and more to figures like Schopenhauer who sought to develop a synthesis of Kant and ideas from South Asian philosophy. Perhaps, we might say, Kant has been sitting under the Bodhi tree all along? (shrink)

We introduce the **Compressed Probabilistic Yoneda Tree (CPYT)**, a framework for representing, comparing, and compressing probability distributions. By integrating Yoneda lemma principles, minimum spanning trees (MST), and ternary tree structures, CPYT enables a hierarchical and minimal structural representation of distributions based on a selected set of probes (e.g., Markov blankets). This approach allows provably correct reconstruction, comparison, and analysis of complex probabilistic systems without relying on traditional Shannon entropy or Kolmogorov complexity measures.

The felling of the Sycamore Gap tree resulted in a passionate public response, which offers a window into public attitudes of care about the natural environment. The response, however, was inconsistent with other recent tree-loss events, in terms of both magnitude and strength of feeling. To better understand this inconsistency and its consequences, an analysis of public responses to the Sycamore Gap event, and other comparative tree-loss events, has been performed. This reveals that the expressions particularly convey moral sentiments concerning (...) the instrumental and aesthetic value of the tree, with little recognition of intrinsic value. Following an environmental care ethics approach, I argue that these responses don’t reflect an authentic care about nature but instead a desire to care about nature. The absence of an appropriate appreciation of the non-anthropocentric identity of nature results in an epistemically-constrained ethical response, reduced individual agency, and thus limited environmental responsiveness.

In Sense and Content , Christopher Peacocke points out that two equally-sized trees at different distances from the perceiver are normally represented to be the same size, despite the fact that in a certain sense the nearer tree looks bigger ; he concludes on the basis of this observation that visual experiences possess irreducibly phenomenal properties. This argument has received the most attention of all of Peacocke’s arguments for separatism—the view that the intentional and phenomenal properties of experiences are (...) independent of one another. However, despite its notoriety, the argument is widely misunderstood and underappreciated. I argue that once the structure of the argument is clarified and the replies that have been offered are considered closely, one must conclude that the trees argument is successful. (shrink)

Fred shows how problems with Slater's restriction of the classical propositional logic can be solved.

Pereira’s “The Projective Theory of Consciousness” is an experimental statement, drawing on many diverse sources, exploring how consciousness might be produced by a projective mechanism that results both in private selves and an experienced world. Unfortunately, pulling together so many unrelated sources and methods means none gets full attention. Furthermore, it seems to me that the uncomfortable breadth of this paper unnecessarily complicates his project; in fact it may hide what it seeks to reveal. If this conglomeration of diverse sources (...) and methods were compared to trees, the reader may feel like the explorer who cannot see the forest for the trees. Then again, it may be the author who is so preoccupied with foreground figures that the everpresent background is ultimately obscured. (shrink)

This phenomenological investigation explores the philosophical implications of sustained morning dialogues between a human interlocutor and a murder of crows (Corvus brachyrhynchos). Through daily pre-dawn lectures delivered beneath what has been designated "the Murder Tree," this study examines fundamental questions about consciousness, intersubjectivity, and the nature of pedagogical exchange across species boundaries. Drawing from continental philosophy, particularly the works of Merleau-Ponty, Levinas, and Derrida, as well as contemporary animal studies and biosemiotics, this treatise argues for a radical reconceptualization of teaching (...) as a bidirectional performative act that transcends anthropocentric models of knowledge transmission. The central thesis posits that these interspecies encounters reveal what I term the "mutual entertainment hypothesis"—a reciprocal framework of engagement that challenges Western philosophy's traditional subject-object dichotomy and suggests new modalities for understanding non-human consciousness and communication.

A complete axiomatic system CTL$_{rp}$ is introduced for a temporal logic for finitely branching $\omega^+$-trees in a temporal language extended with so called reference pointers. Syntactic and semantic interpretations are constructed for the branching time computation tree logic CTL$^{*}$ into CTL$_{rp}$. In particular, that yields a complete axiomatization for the translations of all valid CTL$^{*}$-formulae. Thus, the temporal logic with reference pointers is brought forward as a simpler (with no path quantifiers), but in a way more expressive medium for (...) reasoning about branching time. (shrink)

This paper introduces the "Decision Tree Theory of Life," a philosophical model that describes human life as a branching structure of choices and consequences. Drawing from analogies in computer science, psychology, ethics, and law, it proposes that a person's actions can be evaluated based on how much of their decisions are truly self-authored versus environmentally influenced. This theory suggests a practical threshold called the "50% Authorship Rule," which can be used to assess moral and legal accountability.

This paper structurally resolves one of philosophy’s oldest questions: If a tree falls in the forest and no one hears it, does it make a sound? Using Collapse Theory, it reframes sound not as vibration, but as meaning—a resolution that only emerges when a conscious system collapses signal into structure. From unobserved trees to unheard jokes, from animal reflex to human recursion, the logic holds. Sound is not caused. It is collapsed.

This paper presents an analysis of Seneca's 58th letter to Lucilius and Porphyry's Isagoge, which were the origin of the tree diagrams that became popular in philosophy and logic from the early Middle Ages onwards. These diagrams visualise the extent to which a concept can be understood as a category, genus, species or individual and what the method of dihairesis (division) means. The paper explores the dissimilarities between Seneca's and Porphyry's tree structures, scrutinising them through the perspective of modern graph (...) theory. Although traditional trees can be interpreted in a modern way, their terms and definitions defy modern standardisation. These distinctions are not only useful for differentiating between Seneca's and Porphyry's trees, but also for comprehending the evolution of this philosophical tradition. Thus the paper highlights the continued significance of these tree diagrams in analysing concepts and categories in philosophy and structuring objects and information in modern fields such as artificial intelligence, computer science, bioinformatics, graph theory, and many more.

Cloud computing (ClC) has become a more popular computer paradigm in the preceding few years. Quality of Service (QoS) is becoming a crucial issue in service alteration because of the rapid growth in the number of cloud services. When evaluating cloud service functioning using several performance measures, the issue becomes more complex and non-trivial. It is therefore quite difficult and crucial for consumers to choose the best cloud service. The user's choices are provided in a quantifiable manner in the current (...) methods for choosing cloud services. Hence, this study attempts to achieve this objective through construction. decision-making framework so-called cloud services evaluator (CSsEv). The main indicator and its sub-indicators are formed as nodes at levels(n) in tree soft sets (TSSs). Thereafter Single Value Neutrosophic Sets (SVNSs) as branch of neutrosophic sets which conjunction with the Multi-Criteria Decision Making (MCDM) technique to facilitate analysis and evaluation process for the available Cloud services providers. Hence, entropy is employed to obtain indicators and sub_indicators weights and Complex Proportional Assessment utilizes these weights to facilitate the decision process of selecting optimal ClSPs.

A multitude of uncertainty models, such as fuzzy, neutrosophic, and plithogenic sets, have emerged in the domain of fuzzy sets and their extensions. This diversity, while reflecting an active research community, can lead to conceptual overlap. To address this, the authors propose a unified framework for the systematic management of these "Uncertain Sets" by defining the Uncertain Model, the U-Structure, and the U-Off Structure. The paper revisits and extends the definitions of HyperUncertain, SuperUncertain, SuperHyperUncertain, Tree Uncertain, and Forest Uncertain structures, (...) along with their "Off" variants. To encompass systems beyond Uncertain Sets, the concepts of Functorial Set and Functorial Structure are also introduced. This comprehensive approach aims to establish a robust foundation for organizing and applying uncertainty models across various mathematical and applied domains. (shrink)

How can humanist principles of respect, dignity, and care inform and improve design for non-human lifeforms? This paper uses ageing and dying urban trees to understand how architectural, urban, and landscape design respond to nonhuman concerns. It draws on research in plant sciences, environmental history, ethics, environmental management, and urban design to ask: how can more-than-human ethics improve multispecies cohabitation in urban forests? The paper hypothesises that concepts of dignity and respect can underline the capabilities of nonhuman lifeforms and (...) lead to improved designs for multispecies cohabitation. To investigate the implications of this ethical framework, we 1) indicate injustices of current management in relation to natural and cultural histories of trees; 2) outline a conceptual framework that includes large old trees as stakeholders in urban communities; and 3) use this framework in a thought experiment with urban trees in Melbourne, outlining comparative design outcomes. Our findings show that the expansion of dignity to include nonhuman life is possible and plausible. Such an extension can justify and encourage design innovation for multiple species and sites. The resulting design practices will lead to improvements by supporting communities of trees at all stages of their life-cycles, including old age, death, and rebirth. This approach requires substantial shifts in accepted thinking and practices including history, ethics, aesthetics, regulation, and education. Design can play a significant role in the necessary transitions by demonstrating tangible and positive outcomes. In this context, history emerges as an essential tool that can extend societal imagination by situating possible future places in the context of ancient and ongoing geological, evolutionary, ecological, and cultural processes.

In this paper we introduce a Gentzen calculus for (a functionally complete variant of) Belnap's logic in which establishing the provability of a sequent in general requires \emph{two} proof trees, one establishing that whenever all premises are true some conclusion is true and one that guarantees the falsity of at least one premise if all conclusions are false. The calculus can also be put to use in proving that one statement \emph{necessarily approximates} another, where necessary approximation is a natural (...) dual of entailment. The calculus, and its tableau variant, not only capture the classical connectives, but also the `information' connectives of four-valued Belnap logics. This answers a question by Avron. (shrink)

This paper discusses similarities of both form and meaning between two symbolic structures: the Diagram of the Supreme Pole of Song Neo-Confucianism and the Kabbalistic Tree of medieval Jewish mysticism. These similarities are remarkable in the light of the many differences that exist between Chinese and Judaic thought, which also manifest in the two symbols. Intercultural influence might account for the similarities, but there is no historical evidence for such influence. An alternative explanation would attribute the similarities to the ubiquity (...) of religious-philosophical ideas about hierarchy, polarity, and macrocosm-microcosm parallelism, but this does not adequately account for the similar overall structure of the symbols. The question of how to understand these similarities remains open. (shrink)

Observational and experimental discoveries of new factual entities such as objects, systems, or processes, are major contributors to some advances in the life sciences. Yet, whereas discovery of theories was extensively deliberated by philosophers of science, very little philosophical attention was paid to the discovery of factual entities. This paper examines historical and philosophical aspects of the experimental discovery by Carl Woese of archaea, prokaryotes that comprise one of the three principal domains of the phylogenetic tree. Borrowing Kuhn’s terminology, this (...) discovery of a major biological entity was made during a ‘normal science’ project of building molecular taxonomy for prokaryotes. Unexpectedly, however, an observed anomaly instigated the discovery of archaea. Substantiation of the existence of the new archaeal entity and consequent reconstruction of the phylogenetic tree prompted replacement of a long-held model of a prokarya and eukarya bipartite tree of life by a new model of a tripartite tree comprising of bacteria, archaea, and eukarya. This paper explores the history and philosophical implications of the progression of Woese’s project from normal science to anomaly-instigated model-changing discovery. It is also shown that the consequential discoveries of RNA splicing and of ribozymes were similarly prompted by unexpected irregularities during normal science activities. It is thus submitted that some discoveries of factual biological entities are triggered by unforeseen observational or experimental anomalies. (shrink)

In an online, participatory class, we interpreted 'The Dream of Geese Nesting in Trees' knowing nothing of the dreamer beyond age and gender, and having none of the dreamer’s associations. Our interpretation included predictions about the dreamer. When it was complete, we asked the bringer of the dream (who had until then been mostly silent and who also gave no visual feedback to our discussion) to give us more information about the dreamer. Our main predictions were confirmed. Goslings are (...) falling on the dreamer’s head. This record is another iteration of an experiment that will be described more fully in the paper, 'The Dream of the Six-Legged Dog: An Experimental System that Tests Meaning,' soon to be published. This iteration repeats and confirms the evidence given in that paper. AUDIO RECORD OF COMPLETE CLASS: link is at top of paper you can download from this page. (shrink)

Some ideas on Political Philosophy and Social Anthropology.

This document provides the canonical structural registry of the Paton System as of 24 February 2026. It presents the hierarchical organisation of foundational principles, admissibility laws, operator layers, boundary theorems, domain extensions, and interpretive components within a single ordered tree structure. The registry is strictly classificatory and introduces no new formal mechanisms. Its function is structural governance: to display dependency relations, logical placement, and reduction pathways within the system. The Unified Datum Line (Minimal Formal Statement) serves as the foundational reduction, (...) and all higher-tier constructs are positioned relative to that admissibility-with-memory law. This document functions as a structural map rather than a theoretical extension. (shrink)

In a previous article, Philosophy of Blockchain Technology - Ontologies, I talked about applying Paul Ricœur's narrative theory in developing an ontology of blockchain technology. In this article I intend to highlight the idea of an analogy between blockchain technology and the causal theories of reference. Such a theory can be interpreted as a result of syntactic notation in a reference field, based on the narrative theory developed by Paul Ricœur in Time and Narrative.

Modal collapse arguments are all the rage in certain philosophical circles as of late. The arguments purport to show that classical theism entails the absurdly fatalistic conclusion that everything exists necessarily. My first aim in this paper is bold: to put an end to action-based modal collapse arguments against classical theism. To accomplish this, I first articulate the ‘Simple Modal Collapse Argument’ and then characterize and defend Tomaszewski’s criticism thereof. Second, I critically examine Mullins’ new modal collapse argument formulated in (...) response to the aforementioned criticism. I argue that Mullins’ new argument does not succeed. Third, I critically examine a powers-based modal collapse argument against classical theism that has received much less attention in the literature. Fourth, I show why God’s being purely actual, as well God’s being identical to each of God’s acts, simply cannot entail modal collapse given indeterministic causation. This, I take it, signals the death of modal collapse arguments. But not all hope is lost for proponents of modal collapse arguments—for the death is a fruitful one insofar as it paves the way for new inquiry into at least two new potential problems for classical theism. Showing this is my paper’s second aim. (shrink)

Internodons are a formalization of Hennig's concept of species. We present an alternative construction of internodons imposing a tree structure on the genealogical network. We prove that the segments (trivial unary trees) from this tree structure are precisely the internodons. We obtain the following spin-offs. First, the generated tree turns out to be an organismal tree of life. Second, this organismal tree is homeomorphic to the phylogenetic Hennigian species tree of life, implying the discovery of a multi-level tree of (...) life: this phylogenetic tree can be obtained by zooming out from the organismal tree, or conversely, the organismal tree of life can be generated by expanding the phylogenetic nodes into unary trees. Finally, the definition of the organismal tree allows an efficient algorithmic transformation of a given genealogical network into its corresponding phylogenetic species tree of life. The latter will be presented in a separate paper. (shrink)
