This article brings to light a complex ‘dynamic of errors’ which Albert, in his Commentary on Aristotle’s Physica, uses to elaborate on the problem of the void. In his analysis, the Dominican philosopher addresses issues such as the void’s definition, its existence, or its relationship to motion, while stating his own position on the matter, which heavily relies on Aristotle. Albert argues that the errors made by certain pre-Socratic philosophers (in particular, Anaxagoras, Leucippus, Democritus, Xuthus, and Pythagoras) contributed to the (...) formation of flawed doctrines in the Middle Ages, such as that of Avempace (alongside whom Albert mistakenly places Avicenna). By identifying and exposing ‘errors’ Albert creates a valuable vantage point to address the problem of the void, whilst emphasizing the significant role played by pre-Socratic thinkers in the emergence and evolution of scientific discourse on the issue.

This paper explores three questions concerning Democritus’ moral philosophy. First, do Democritus’ moral claims constitute a genuine ethical theory (the Theory Question)? Second, if so, is Democritus’ ethical framework part of the eudaimonistic tradition of his contemporaries and successors, namely Socrates, Plato, Aristotle, Epicurus, and the Stoics (the Eudaimonism Question)? Third, if Democritus is an eudaimonist, is there a necessary relationship between his ethics and the other areas of his philosophy (the Strength Question)? I argue that Democritus is an eudaimonist, (...) but only in the weak sense. (shrink)

In a problematic passage at the beginning of his treatise De Mixtione (I, 1.9–16), Alexander of Aphrodisias judges Chrysippus’ theory of total blending to be more paradoxical than two other paradoxical claims on mixture. Scholars understand these two claims either as a unitary position or as two distinct positions. In the latter case, they maintain that an emendation is necessary to make sense of the first claim. Through textual and philosophical analysis, this article shows that the claims represent two distinct (...) positions—the realist view and Democritus’ reductionist account—and that no emendation is necessary. The article defends the transmitted text by explaining how Alexander can characterize the realist view as paradoxical despite endorsing it himself. To do so, it illustrates the meaning of ‘paradoxical’ in light of Alexander’s use of common notions (koinai ennoiai) as evaluative criteria and thoroughly connects the passage to the wider dialectical framework of the De Mixtione, thus reconstructing the rationale behind Alexander’s evaluation of each of these three positions as paradoxical.

This paper addresses Democritus' conception of the void as absolute nothingness, a foundational idea in his philosophy that postulates the void as a necessary condition for atomic motion. By analyzing the logical and ontological paradoxes inherent in his view, the discussion demonstrates that the void, as defined by Democritus, cannot exist as pure absence. Instead, it is reinterpreted as "pure space" or "indeterminate spaciousness," which possesses intrinsic structural and relational properties, making it a condition for the manifestation of reality. The (...) paper introduces a quantum-dynamic perspective on motion, contrasting it with Democritus' mechanical model. In this framework, motion is not the translation of objects through an empty void but the result of continuous modifications within the dynamic quantum field or space itself. A thought experiment with a curtain and a light beam illustrates how motion arises as a perceptual phenomenon from spatial modifications rather than physical displacement. This reinterpretation resolves Democritus' challenge by rejecting the need for a void as absolute nothingness. Instead, motion and space are unified within the quantum-dynamic model as inseparable aspects of reality. The analysis concludes by framing space and motion as expressions of Divine Fullness, offering a richer understanding of reality's dynamic nature. (shrink)

La explicación tradicional del concepto de "vacío" (τò κενóν) en la filosofía antigua lo sitúa como una invención del atomismo de Demócrito y Leucipo o, incluso, del eleático Meliso de Samos. De esta manera se ocultan las profundas razones que pudieron llevar a la necesidad y surgimiento de un tal concepto, y aparece como si hubiera sido creado ex nihilo. En este artículo se pretende descubrir tanto el principio mitológico como el origen racional del concepto de "vacío" en la filosofía (...) presocrática, que lo sitúa como anterior a las historias contadas hasta ahora. Mediante dos columnas que intentan aprehender lo mismo desde puntos de vista distintos, se llegará a la conclusión de que el concepto de "vacío" fue definido en el inicio como diferencia y repetición. En contra de una determinada visión de la historia de la filosofía que ve a los "clásicos" y a los "modernos" como dos compartimentos separados e incluso enfrentados, en el curso de esta interpretación se establecerá un diálogo entre la doxografía presocrática y la filosofía contemporánea de Schelling, Hegel, Nietzsche, Heidegger, Schmitt, Irigaray, Derrida o Deleuze.

I argue that a circa first century B.C./A.D. anonymous epistolary comic novel depicting a fictional interaction between Hippocrates of Cos and Democritus of Abdera contains an insightful imitation of Democritus that can cast light on the historical Democritus’s thought, including his thought on the touchy subject of appropriate and inappropriate laughter. The only thing certain about Democritus’s view of laughter is that he denounced laughter at human misfortune as inappropriate. The later legend of him as laughing at everything and everyone (...) indiscriminately is a later distortion of his view which the author of the comic novel seems concerned to counteract. (shrink)

This chapter situates Karl Marx’s dissertation The Difference between the Democritean and Epicurean Philosophy of Nature (1841) within his intellectual biography. It explores the role of a German ideal known as Bildung, translated as “education”, “cultivation” or “culture”, within Marx’s classical education in the Gymnasium and the dissertation itself. Both Wilhelm von Humboldt, who reformed the Gymnasium curriculum prior to Marx’s attendance, and philosopher G.W.F. Hegel have classically inspired notions of Bildung. Each presents the white European man as the model (...) for this “education” or “cultivation”. This chapter argues that the dissertation assimilates Epicurus and his atom into this Eurocentric paradigm, with Marx taking for granted his predecessors’ racist teleology of history and applying their conception of the individual to the atom. Then, it addresses the dissertation’s influence in the development of historical materialism, a facet of Marxism already critiqued for its Eurocentrism. This chapter concludes by showing how non-White and non-Western Marxists have updated Marxist thought through constant critique of its Eurocentrism instead of abandoning its revolutionary vision. It suggests that Marxism is relevant to scholars of antiquity not because of the dissertation but the tradition’s self-interrogation of its foundational ideas and persistent focus on improving the conditions of the marginalised.

Les interprétations et traductions habituelles de l’affirmation d’Aristote en Métaphysique Λ, 1075b12-13 πάντες δ᾽ οἱ τἀναντία λέγοντες οὐ χρῶνται τοῖς ἐναντίοις, ἐὰν μὴ ῥυθμίσῃ τις se fondent sur une compréhension contestable de la signification du verbe ῥυθμίζω. Une brève analyse de la signification et de l’usage du verbe au ve et ive siècle av. J.-C., ainsi qu’une étude des principaux interprètes anciens et médiévaux (le Ps.-Alexandre, Thomas d’Aquin, Averroès, Thémistius), dévoilent les difficultés que la compréhension de ce passage d’Aristote suscitaient (...) dès l’Antiquité et permettent de supposer que ῥυθμίζω doit ici être entendu dans son sens technique, métaphysique (« former », « ajouter une forme »), selon un usage que l’on trouve aussi chez Démocrite et Antiphon. La compréhension correcte de ce verbe autorise alors à présenter une nouvelle interprétation de ce bref passage d’Aristote et d’y découvrir une critique plus complète et précise des thèses qu’il entend dénoncer.

The research is a comparative study of the atomic theories of Kanada and Democritus. Because of their pluralistic tendencies, emphasis on causality, materialistic account of sense knowledge, and attempt to explain the physical system by means of reduction to the configuration of its constitutive elements, both philosophers present an epistemological base that could accommodate scientific inquiry. Notwithstanding the early and expansive beginning of Indian atomism, modern scientific atomic theory traces its origin to Democritus. Through cross-cultural critical engagement with parallel ideas (...) between Kanada and Democritus, the paper aims to discover the common problems they dealt with in order to further our understanding of the early history of atomic theory, to evaluate the relative merits and limitations of their proposed solutions, to resolve some difficulties that each account faces by appealing to the other, and to highlight their contributions to the emergence of the atomic worldview.

Both Heraclitus and Democritus, as the philosophers of historia peri phuseôs, consider nature and human character, habit, law and soul as interrelated emphasizing the links between phusis, kinesis, ethos, logos, kresis, nomos and daimon. On the one hand, Heraclitus’s principle of change (panta rhei) and his emphasis on the element of fire and cosmic motion ultimately dominate his ethics reinforcing his ideas of change, moderation, balance and justice, on the other, Democritus’s atomist description of phusis and motion underlies his principle (...) of moderation and his ideas of health and measured life. In this series, particularly referring to the main principles of motion, moderation and justice, I attempt to describe a coherent pre-Socratic ethical perspective based on the Heraclitean and Democritean fragments. I explore the connections between their physics and ethics also borrowing from Nietzsche’s lectures and writings on the Pre-Socratics. I redefine such Heraclitean and Democritean concepts as harmony, order, perfection, health, self-control, contentment, cheerfulness, concord, sound judgment, wisdom, measure and balance and discuss them under the principles of motion (phusis), moderation (sophrosyne) and justice. In doing so, I also expose the relevance of the Heraclitean notion of logos (interpreting it as the underlying categorical principle of transition between phusis and ethos) in bringing together these ideas and principles. Finally, based on this pre-Socratic Weltanschauung, I assess the possibility of a coherent picture of humanity, its nature and conduct as extending from or fitting into or extending-from-when-fitting-into the cosmos of moving forces and atoms.

Democritus of Abdera, best known as a cosmologist and the founder of atomism, wrote more on ethics than anyone before Plato. His work Peri euthumiês (On Contentment) was extremely influential on the later development of teleological and intellectualist ethics, eudaimonism, hedonism, therapeutic ethics, and positive psychology. The loss of his works, however, and the transmission of his fragments in collections of maxims (gnomai), has obscured the extent his contribution to the history of systematic ethics and influence on later philosophy, especially (...) in the Hellenistic age. In this essay I review the evidence basis for Democritus’ ethics, discuss the rhetorical and logical aspects of his maxims, attempt to synthesize the fragments into an overall interpretation, and offer a summary some of the more influential aspects of his ethics.

Greco-Roman meteorology will be described in four overlapping developments. In the archaic period, astro-meteorological calendars were written down, and one appears in Hesiod’s Works and Days; such calendars or almanacs originated thousands of years earlier in Mesopotamia. In the second development, also in the archaic period, the pioneers of prose writing began writing speculative naturalistic explanations of meteorological phenomena: Anaximander, followed by Heraclitus, Anaxagoras, and others. When Aristotle in the fourth century BCE mentions the ‘inquiry that all our predecessors have (...) been calling meteorology’ (338a26), he is referring to these writers. In the third development, the first two enterprises were combined: empirical data collection about meteorological phenomena began to be married to naturalistic theoretical explanation. This innovation was prompted by Democritus and synthesised in its most influential form by Aristotle. At this point more sophisticated techniques of both short-term weather forecasting and long-term speculation about global climate change were also developed. In the fourth development, the wider implications of the naturalistic explanation of meteorological phenomena were contested. The views of ‘meteorologists’ had been controversial since the archaic period because they were perceived, and sometimes intended, to displace the divine prerogatives and undermine traditional religion. These controversies intensified throughout the classical and Hellenistic periods. (shrink)

Encyclopedia article on Democritus. Includes a brief overview of his philosophical views, major works, and critical reception.

In this article, we start from the general thesis of theatomism – everything in the universe is composed by atoms – toassume an atomist reading of the ethical fragments of Democritus.If Leucippus and Democritus explain not only the beginning of the world, as well as the constitution of the soul and the body from therelation atom-emptiness (to be-not to be), this structure will also beapplied to the ethical maxims that we know. Despite this, the relationsoul-body is one of superiority (the (...) knowledge that drift of the sensations it’s obscure), it is also of interdependence, that leads Democritusto blame soul when body is only a tool of its vices or the need to takecare of soul and body in the same way. However, it is in the soul thatwe must look for true knowledge (subtle), as well as the pleasures thatvalue the man. From this relation, we will also analyse the consequencesin the education as well as in the life in society. (shrink)

Hynek Bartos does the field of ancient philosophy a great service by detailing the influence of early Greek thinkers (such as Heraclitus, Empedocles, Anaxagoras, Democritus, and Diogenes of Apollonia) on the Hippocratic work On Regimen, and by demonstrating that work’s innovative engagement with contemporary scientific and philosophical concepts as well as its direct influence on Plato and Aristotle. His study usefully counteracts the lamentable tendency among ancient philosophers to ignore or downplay the influence of medical literature on philosophy in general, (...) and to heap scorn on this text in particular, which Kirk, Raven, and Schofield considered ‘an eclectic and very superficial quasi- philosophical treatise’ and Barnes famously called ‘a silly farrago of ill-digested Presocratic opinions’.

In Metaphysics A.4 (985b4-19 [DK67 A6]), Aristotle provides crucial information about fundamental aspects of the chemistry and microphysics of the atomic theory of Leucippus and Democritus of Abdera. Besides the plenum and the void, which he identifies as the elements of the atomic theory, he presents what he himself names as differences. These fundamental differences are named so because they ought to be responsible for the emergence of all other differences in the physical world, and especially the ones that hit (...) our senses. Aristotle provides a list of three differences both in what is recognized as autochthonous terminology from Leucippus and Democritus, and in a translation to terms apparently more intelligible to Aristotelian listeners. Among those differences there is one in particular that is harder to comprehend than the other ones: rhysmos. Aristotle’s translation of rhysmos into schēma has led most interpreters to acknowledge that it referred solely to atoms individually, while the other two differences would refer to relations between atoms. In this paper, I want to propose an interpretation in which rhysmos actually refers to several aspects of the chemistry and microphysics of the atomic theory. (shrink)

The concept of kosmos did not play the leading role in Aristotle’s physics that it did in Pythagorean, Atomistic, Platonic, or Stoic physics. Although Aristotle greatly influenced the history of cosmology, he does not himself recognize a science of cosmology, a science taking the kosmos itself as the object of study with its own phenomena to be explained and its own principles that explain them. The term kosmos played an important role in two aspects of his predecessor’s accounts that Aristotle (...) rejected: first, cosmogeny and kosmopoiia, generation or creation of the kosmos; second, diakosmêsis, arranging of a plurality of kosmoi. Aristotle was extremely critical of accounts involving kosmopoiia and diakosmêsis and he developed general dialectical strategies against them. In emphatically distinguishing his view from all his predecessors (including Plato), he uses the terms ho ouranos (the heaven), to holon (the whole), and to pan (the totality) in preference to ho kosmos (the kosmos or world). There is usually no harm in speaking loosely of ‘Aristotle’s cosmology’ when referring to his concept of the order of nature and the ouranos. Nevertheless, Aristotle’s theoretical philosophy offers something very different from those of his predecessors for whom kosmos was a keyword. (shrink)

In this paper, I discuss the use made by Aristotle of the term “element” when dealing with the atomist theory of Leucippus and Democritus. My goal is to verify which aspects of the atomist theory play the role of elements according to the definitions of Aristotle, who seems to have certain expectations regarding what can be designated as elements in the strict sense. One of them is the possibility of reciprocal transformation, the so-called “generation of elements”, which is the chemical (...) aspect at the level of the simple bodies that makes change possible at the level of sense-perceived bodies. Furthermore, I evaluate whether it is possible to find and whether it is adequate to speak of the presence of the four elements – fire, air, water and earth – in the atomist doctrine. (shrink)

Encyclopedia article briefly summarizing the history of atomism from antiquity to modernity.

I develop a positive interpretation of Democritus' theory of agency and responsibility, building on previous studies that have already gone far in demonstrating his innovativeness and importance to the history and philosophy of these concepts. The interpretation will be defended by a synthesis of several familiar ethical fragments and maxims presented in the framework of an ancient problem that, unlike the problem of free will and determinism, Democritus almost certainly did confront: the problem of the causes of human goodness and (...) success. I will argue that Democritus' account of the virtues and success is naturally interpreted as an intellectualist one. His focus on our intellectual powers as the source of our own agency and cause of our success led him to remarkable breakthroughs in moral psychology, including the development of a kind of cognitive-behavioral therapy for stress and anxiety, and the proposal of an autonomous source of moral sanction.

The testimonia concerning weight in early Greek atomism appear to contradict one another. Some reports assert that the atoms do have weight, while others outright deny weight as a property of the atoms. A common solution to this apparent contradiction divides the testimonia into two groups. The first group describes the atoms within a κόσμος, where they have weight; the second group describes the atoms outside of a κόσμος, where they are weightless. A key testimonium for proponents of this solution (...) is Aëtius 1.3.18. It apparently denies weight as a property of the atoms, and supposedly describes the atoms when they are outside of a κόσμος. I argue against this interpretive solution by demonstrating, first, that Aëtius 1.3.18 does not deny that weight is a property of the atoms. Second, I argue that the report does not describe the atoms when they are outside of a κόσμος. Although these are largely negative conclusions, I contend that we are not left without a solution to the present interpretive difficulty. Once our testimonia concerning weight in early Greek atomism are examined thoroughly, it is clear that there is no conflict among them. (shrink)

One striking oddity about Democritus and Epicurus is that, even though Epicurus' theory of perception is largely the same as that of Democritus, Democritus and his followers draw skeptical conclusions from this theory of perception, whereas Epicurus declares that all perceptions are true or real. I believe that the dispute between Democritus and Epicurus stems from a question over what sort of ontological status should be assigned to sensible qualities. In this paper, I address three questions: 1) Why were Democritus (...) and his followers skeptical? 2) How did Epicurus modify Democritus' metaphysics in order to avoid these skeptical conclusions? and 3) How successful was he? -/- 1) I argue that Democritus allows only the intrinsic properties of atoms into his ontology, and then runs into skeptical difficulties because of the relativity of perception. 2) I propose that Epicurus modifies Democritus' ontology by allowing dispositional and relational properties as real properties of bodies. Sensible qualities are conceptualized as dispositional properties of bodies to cause certain experiences in percipients. 3) I argue that Epicurus does not run into the same problems as Democritus. Finally, I consider how my interpretation of Epicurus' ontology helps to make sense of his claim that all perceptions are alethes--'true' or 'real.'. (shrink)

Critics have alleged that Democritus’ ethical prescriptions (“gnomai”) are incompatible with his physics, since his atomism seems committed to necessity or chance (or an awkward combination of both) as a universal cause of everything, leaving no room for personal responsibility. I argue that Democritus’ critics, both ancient and contemporary, have misunderstood a fundamental concept of his causality: a cause called “spontaneity”, which Democritus evidently considered a necessary (not chance) cause, compatible with human freedom, of both atomic motion and human actions. (...) Some influential contemporary compatibilists have argued that freedom and responsibility are compatible with causal determinism, but not intentional constraint where some other agent is intentionally manipulating or coercing one’s actions. In line with this, Democritus holds that humans should not blame their actions on other agents like the gods, or agent-like external forces like fate or chance, but should assume ultimate intentional control over their own choices and actions. The famous remark of his associate Leucippus that “everything happens for a reason and out of necessity” is a fitting slogan of their atomistic philosophy, for Democritus pursued what can without anachronism be recognized as a causal theory of freedom.

There are two links that stand in the foreground of Deleuze’s treatment of Epicurus and Lucretius: the themes of immanent naturalism and of the externality of ontological relations. However, the links are problematised in Difference and Repetition, which presents an important critique of the concept of the atom. I will argue that this critique reveals the limits of the intellectual affinity between ancient atomism and Deleuzian metaphysics; in particular, that Deleuze’s notions of relationality and spatium respond to problems raised by (...) the relations between atoms and by the not-being of the atomists’ vacuum. In this sense, Deleuze’s treatment of atomism is significant because it makes clear Deleuze’s aim in shifting the mereological vocabulary from points to lines; it shows what, in Deleuze’s sense, it means to unfound and sets down the conditions for a successful Deleuzian critique of essentialist varieties of the metaphysics of structure.

But Aristotle’s model of "the material" remains the material out of which an artifact is made. (shrink)
