According to Popper's rationality principle, agents act in the most adequate way according to the objective situation. I propose a new interpretation of the rationality principle as consisting of an idealization and two abstractions. Based on this new interpretation, I critically discuss the privileged status that Popper ascribes to it as an integral part of all social scientific models. I argue that as an idealization, the rationality principle may play an important role in the (...) social sciences, but it also has inherent limitations that inhibit it from having the privileged status that Popper ascribes to it in all cases.

In the social sciences, within the explanatory paradigm of structural individualism, a theory of action – like rational choice theory – models how individuals behave and interact at the micro level in order to explain macro observations as the aggregation of these individuals actions. A central epistemological issue is that such theoretical models are stuck in a dilemma between falsity of their basic assumptions and triviality of their explanation. On the one hand, models which have a great empirical success often (...) rest on unrealistic or even knowingly false assumptions; on the other hand, more complex models, with additional more realistic hypotheses, can (trivially) adapt to a wide range of situations and thus loose their explanatory power. Our purpose here is epistemological and consists in wondering to which extent demanding realistic assumptions in such cases is a relevant criterion with respect to the acceptance of a given explanatory model. Via an analogical reasoning with physics, we argue that this criterion seems too strong and actually irrelevant. General physical principles are not just idealized or unrealistic, they can also be formulated in many different yet equivalent ways which do not imply the same fundamental unobservable entities or phenomena. However, the classification of phenomena that such principles allow to highlight does not depend, at the end, on any particular formulation of these basic assumptions. This suggests that some hypotheses in theoretical models are actually not genuine empirical statements that could be independently tested but only substrates of modeling embodying a classification principle. Thus, we develop a structural invariance criterion that we then apply to rational choice models in the social sciences. We argue that this criterion allows to escape from the epistemological dilemma without condemning formal approaches like rational choice theory for their lack of realisticness nor being stuck to any antirealist viewpoint.

According to the received view in metaethics, a Neo-Humean theory of rationality entails that there cannot be any objective moral reasons, i.e. moral reasons that are independent of actual desires. In this paper, I argue that there is a version of this theory that is compatible with the existence of objective moral reasons. The key is to distinguish between (i) the process of rational deliberation that starts off in an agent's actual desires, and (ii) the rational principle that (...) an agent employs in such a process. I maintain that it is the latter which explains why it is rational for an agent to have a certain desire, not the former. As a result, there might be two types of principles. The second type of principle leaves room for objective moral reasons. (shrink)

In this paper I argue that the enkratic principle in its classic formulation may not be a requirement of rationality. The investigation of whether it is leads to some important methodological insights into the study of rationality. I also consider the possibility that we should consider rational requirements as a subset of a broader category of agential requirements.

Ludwig deals with the relations between language, thought, and rationality, and, especially, the role and status of assumptions about rationality in interpreting another’s speech and assigning contents to her psychological attitudes—her beliefs, desires, intentions, and so on. The chapter is organized around three questions: What is the relation between rationality and thought? What is the relation between rationality and language? What is the relation between thought and language? Ludwig argues that some large degree of rationality (...) is required for thought and consequently that same degree of rationality at least is required for language since language requires thought. Thought, however, does not require language. In answering questions and, Ludwig gives particular attention to Davidson’s arguments for the Principle of Charity, according to which it is constitutive of speakers that they are largely rational and largely right about the world, and to Davidson’s arguments for the thesis that without the power of speech we lack the power of thought.

The objective of the research is to test the feasibility of implementing Structured Rational Thinking to learn disciplinary principles, evaluate written language, and answer the questions: What are its epistemological foundations? What explains why rational thinking is not common in people? How do students modify their conceptualization of thematic principles through it? And how does it help students to build knowledge and express it? Rational thinking was theoretically framed and its derivation into types of structured thinking: logical, methodical, and narrative; (...) and its characterization according to its content, purpose, and structure, in its classical and modern forms. The hypothesis was: "people stop thinking rationally due to the lack of applying a method to order and properly conduct thoughts; one aspect is the method and another is the thought that it generates." Mixed methodology; results, it is expected that 50 students surveyed generate knowledge and language attached to objectified reality. Test 1: the level of understanding was assessed according to types of thinking, in ranges of: little, moderately and a lot, coded with ordinal values in intervals from 0 to 2, by interaction matrix. Test 2: table identifying levels of rational thinking, interval scale: 1 to 2 low level, 3 to 4 medium, 5 to 6 high, more than 6 very high. Conclusions, the effects of not applying a type of thinking that orders ideas to interpret reality and generate proven knowledge, far from conjectures, are outlined. The best thinking, guides reason when faced with compound and dynamic facts. (shrink)

This paper presents a new solution to the problem of peer disagreement that distinguishes two principles of rational belief, here called probability and autonomy. When we discover that we disagree with peers, there is one sense in which we rationally ought to suspend belief, and another in which we rationally ought to retain our original belief. In the first sense, we aim to believe what is most probably true according to our total evidence, including testimony from peers and authorities. In (...) the second, we aim to base our beliefs only on objective evidence and argumentation, even if that lowers the probability of their being true. The first principle of rational belief tends to serve the short-term epistemic interests of individuals, while the second tends to serve the long-term epistemic interests of both individuals and groups. The best way to reconcile these principles in cases of peer disagreement is to associate them with two corresponding species of belief, here called perception and opinion. (shrink)

Bermúdez argues for rational framing effects in the form of quasi-cyclical preferences. This is supposed to refute the extensionality principle in standard decision theory. In response, I argue that it is better to analyze seemingly quasi-cyclical preferences as ceteris paribus preferences. Furthermore, if frames are included as objects of choice, we can acknowledge rational framing effects without rejecting extensionality.

This paper sheds light on Kant’s notion of autonomy in his moral philosophy by considering Kant’s critique of the rationalist theories of morality that Kant discussed in his lectures on practical philosophy from the 1760s to the time of the Groundwork. The paper first explains Kant’s taxonomy of moral theories and his perspective on the history of ethics. Second, it considers Kant's arguments against the two main variants of ‘rationalism’ as he construes it, that is, perfectionism and theological voluntarism, pointing (...) out the similarities to previous criticisms. Third, the paper argues that Kant’s discussion of the 'rationalist' views does not amount to an unqualified dismissal, but to an attempt at working out a novel rationalist position. Kant’s criticisms of rationalist views suggest that his project emerges from the failures of previous rationalism, with the aim to work out a rationalist view that can account for moral obligation by integrating insights from the theological conception. The combination of perfectionism and theological views yields the basic outline of the idea of autonomy, consisting in the lawgiving function of a rational will as a key to the legislation of a necessary law.

Metaphysical rationalism, the doctrine which affirms the Principle of Sufficient Reason (the PSR), is out of favor today. The best argument against it is that it appears to lead to necessitarianism, the claim that all truths are necessarily true. Whatever the intuitive appeal of the PSR, the intuitive appeal of the claim that things could have been otherwise is greater. This problem did not go unnoticed by the great metaphysical rationalists Spinoza and Leibniz. Spinoza’s response was to embrace necessitarianism. (...) Leibniz’s response was to argue that, despite appearances, rationalism does not lead to necessitarianism. This paper examines the debate between these two rationalists and concludes that Leibniz has persuasive grounds for his opinion. This has significant implications both for the plausibility of the PSR and for our understanding of modality. (shrink)

This paper explores an initially attractive principle connecting beliefs in general with beliefs about what beliefs are rational. The principle turns out to be violated by intuitively rational beliefs in some situations. The paper lays out some options for reacting to this fact.

This article shows that there is a liar-like paradox that arises for rational credence that relies only on very weak logical and credal principles. The paradox depends on a weak rational reflection principle, logical principles governing conjunction, and principles governing the relationship between rational credence and proof. To respond to this paradox, we must either reject even very weak rational reflection principles or reject some highly plausible logical or credal principle.

Fichte’s first principle is commonly understood as the absolute or self-positing I. Although this interpretation is not incorrect, it captures only a partial truth. The I that posits itself is intrinsically related to reason: the I is itself reason, and self-positing is the essence and original act of reason. This article argues that only a reason-contextual reading of the first principle reveals its full significance. The argument unfolds in two parts. The first examines a corpus of passages in (...) which Fichte employs the term ‘reason’ and the conceptual frameworks that underlie it. The second addresses three questions arising from this analysis: whether the I is identical with reason; whether Fichte proposes a model that redefines the relation between reason and the I beyond Kant’s; and what strategies can be developed to sustain the reason-contextual reading.

One of Leibniz’s fundamental philosophical commitments is the principle of sufficient reason (PSR). Yet Leibniz’s precise understanding of this principle is elusive. Leibniz provides several seemingly different formulations of its content, and Leibniz sometimes seems to require the PSR being metaphysically necessary and sometimes being metaphysically contingent. I argue that these puzzles can be solved by taking seriously Leibniz’s insistence that the PSR is a principle of reasoning. For Leibniz, I argue, to say that the PSR is (...) a principle of reasoning is to say that it is a regulative principle of rational inquiry, a principle that settles some of the permissible and impermissible moves in the game of rationally inquiring into a fundamentally intelligible reality. According to this reading, there is a coherence between epistemology and metaphysics: for Leibniz, one is epistemologically justified in holding metaphysical doctrines precisely because they result from engaging in the type of rational inquiry structured by the PSR understood as a principle of reasoning.

Normal interpersonal treatment is often based on the existence of the rational nature of both the agent and the target of the treatment, and their relationship is reciprocal and mutual. However, when the rational person confronts the irrational person, such as the mentally retarded or vegetative person, the reciprocal relationship cannot be maintained because the targeted person loses his or her rational capacity. But this inequality does not deprive the object of action of the right to be treated rationally, because (...) people treat the irrationally disabled not according to the principle of reason but according to the principle of emotion - specifically, the principle of love. The principle of love often disregards the specific conditions of the object of treatment and still treats them reasonably. Thus, the emotional principle has a broader application in interpersonal treatment. (shrink)

Permissivism about rationality is the view that there is sometimes more than one rational response to a given body of evidence. In this paper I discuss the relationship between permissivism, deference to rationality, and peer disagreement. I begin by arguing that—contrary to popular opinion—permissivism supports at least a moderate version of conciliationism. I then formulate a worry for permissivism. I show that, given a plausible principle of rational deference, permissive rationality seems to become unstable and to (...) collapse into unique rationality. I conclude with a formulation of a way out of this problem on behalf of the permissivist. (shrink)

Closure for justification is the claim that thinkers are justified in believing the logical consequences of their justified beliefs, at least when those consequences are competently deduced. Many have found this principle to be very plausible. Even more attractive is the special case of Closure known as Single-Premise Closure. In this paper, I present a challenge to Single-Premise Closure. The challenge is based on the phenomenon of rational self-doubt – it can be rational to be less than fully confident (...) in one's beliefs and patterns of reasoning. In rough outline, the argument is as follows: Consider a thinker who deduces a conclusion from a justified initial premise via an incredibly long sequence of small competent deductions. Surely, such a thinker should suspect that he has made a mistake somewhere. And surely, given this, he should not believe the conclusion of the deduction even though he has a justified belief in the initial premise. (shrink)

Conceptual understanding is essential to learn physics principles, for this it is advisable to develop a method of thinking. The Case Method can develop it hence the objectives of research: test the viability of implementing Rational Thought and the Case Metod in classrooms and answer the questions: how does rational thought modify in students conceptualization? and how the Case Method modifies their thinking scheme for learning disciplinary principles? The first stage consisted of theoretically basing classical pedagogy, with the rational thought (...) of ancient Greece and its derivation in scientific thought. For test design, an interaction matrix is proposed to order and interpret data that reflect the level of conceptualization, according to types of structured thought: logical, methodical and narrative; For each type of thought, dimensions of content, purpose and structure are evaluated. In the second stage implement the method with the IGBE model imply: individual activity, Case reading; focus group; plenary; anecdotal log; evaluation judges dimensions understanding; diagnostic surveys and verification of experimental and control groups. The results of first stage: methodological, theoretical and test design foundations were achieved supported by preliminary conclusions. Secondly when implementing the method, the judges evaluated plenary discussion with high levels of understanding. When evaluating logs, the results showed medium and high levels. When implementing diagnostic surveys, similar levels of preconceptions were observed in both groups. When comparing results from verification surveys, higher levels of understanding were observed in the experimental group than in the control group; The method favorably impacts understanding through dialogic socialization.

By laying bare the philosophical prejudices underlying certain modern deprecations of Confucianism, this article defends the integrity of Confucian civilization and reclaims its significance for the modern world. Taking on a typical criticism of Confucian Ethics by Alsadire MacIntyre, I argue that the ideal of Confucian self can be defined neither in terms of Western concepts of autonomy nor heteronomy; it consists rather in a kind of virtuosity as inspired by the empathetic openness of the self. Through a comparative study (...) of Confucian and typical Western ethical theories, I will demonstrate further how the empathetic embodiment of the Confucian self informs an order of ritual that may still be relevant for the modern world in promoting harmonious social and political orders that can elevate the conventional and current power hierarchies into the virtuous rule of benefaction.

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, (...) and rational decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

This chapter is concerned with the distinction that most contemporary epistemologists express by distinguishing between “propositional” and “doxastic” justification. The goal is to develop an account of this distinction that applies, not just to full or outright beliefs, but also to partial credences—and indeed, in principle, to attitudes of all kinds. The standard way of explaining this distinction, in terms of the “basing relation”, is criticized, and an alternative account—the “virtue manifestation” account—is proposed in its place. This account has (...) a certain kinship with the epistemological approach that is known as “reliabilism”, but it also has certain key differences—above all, it is compatible with an internalist view of rationality.

The discussion about deep disagreement has gained significant momentum in the last several years. This discussion often relies on the intuition that deep disagreement is, in some sense, rationally irresolvable. In this paper, I will provide a theory of rationally irresolvable disagreement. Such a theory is interesting in its own right, since it conflicts with the view that rational attitudes and procedures are paradigmatic tools for resolving disagreement. Moreover, I will suggest replacing discussions about deep disagreement with an analysis of (...) rationally irresolvable disagreement, since this notion can be more clearly defined than deep disagreement and captures the basic intuitions underlying deep disagreement. I will first motivate this project by critically assessing the current debate about deep disagreement. I then detail the notions of rationality and resolvable disagreement which are crucial for a suitable theory of rationally irresolvable disagreement before sketching various instances of rationally irresolvable disagreement. Finally, I argue for replacing theories of deep disagreement with theories of rationally irresolvable disagreement, an approach that has significant advantages over existing theories of deep disagreement which focus on hinge propositions or fundamental epistemic principles.

Constitutivist approaches to the normativity of rationality have recently come into vogue. Unlike their moral counterparts, however, they have not been confronted with the shmagency objection. In this paper, I challenge them with two versions of the objection based on recent developments in the debate surrounding the normativity of morality. These are shmagency as modal escapability, which is based on taking sophisticated shmagents to be able to modally escape various norms, and shmagency as underdetermination, which is based on taking (...) constitutive norms that allegedly have independent value to be underdetermined by that value. I consider three different kinds of constitutivist theories of the normativity of rationality: first-person-authority views, single-mental-state views, and systems-of-mental-states views. None of the three are able to deal with either of these shmagency objections. There are sophisticated shmagents who escape all these types of constitutivist principles of rationality, so they are modally escapable, and the value of rationality underdetermines all the views. Upshot: constitutivists about structural rationality ought to worry about shmagency. (shrink)

A theory of rational belief should get the cases right. It should also reach its verdicts using the right theoretical assumptions. Leading theories seem to predict the wrong things. With only one exception, they don't accommodate principles that we should use to explain these verdicts. We offer a theory of rational belief that combines an attractive picture of epistemic desirability with plausible principles connecting desirability to rationality. On our view, it's rational to believe when it's sufficiently likely that you'd (...) know because believing when it's sufficiently likely that you'd know minimises expected objective epistemic undesirability.

I advocate Time-Slice Rationality, the thesis that the relationship between two time-slices of the same person is not importantly different, for purposes of rational evaluation, from the relationship between time-slices of distinct persons. The locus of rationality, so to speak, is the time-slice rather than the temporally extended agent. This claim is motivated by consideration of puzzle cases for personal identity over time and by a very moderate form of internalism about rationality. Time-Slice Rationality conflicts with (...) two proposed principles of rationality, Conditionalization and Reflection. Conditionalization is a diachronic norm saying how your current degrees of belief should fit with your old ones, while Reflection is a norm enjoining you to defer to the degrees of belief that you expect to have in the future. But they are independently problematic and should be replaced by improved, time-slice-centric principles. Conditionalization should be replaced by a synchronic norm saying what degrees of belief you ought to have given your current evidence and Reflection should be replaced by a norm which instructs you to defer to the degrees of belief of agents you take to be experts. These replacement principles do all the work that the old principles were supposed to do while avoiding their problems. In this way, Time-Slice Rationality puts the theory of rationality on firmer foundations and yields better norms than alternative, non-time-slice-centric approaches. (shrink)

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

Logical rationalism asserts that we can acquire immediate, non-inferential justification for beliefs in basic logical principles. The intuitions that arise when we consider particular cases of validity can offer justification for our foundational logical beliefs about rules of inference. I motivate rationalism through an argument from the indispensability of intuitions. This argument shows that rationalism is the theory best equipped to solve the problem of background logic. This is the challenge of explaining how we gain justified beliefs in rules of (...) inference without using those rules in a viciously circular way to arrive at the beliefs. As rationalism is the best epistemology which solves this important challenge, it is our best account of logical knowledge. In addition, I argue that a second major motivation for logical rationalism arises from work on logical practice. Recently, it has been claimed that we should attend to the practices of logicians when selecting an epistemology of logic. I argue that these considerations from logical practice also favour the adoption of logical rationalism. (shrink)

Lately, more and more authors have asserted their belief that one of the criteria which, together with the medical ones, can and should be applied in the policy of selecting and/or prioritizing the patients in need for the allocation of medical resources with limited availability, is the principle of individual responsibility for illness. My intention in this study is to highlight some very serious obstacles looming against the attempt to apply this principle in the distribution of the medical (...) services with limited availability. Although there are numerous such obstacles, I shall only discuss five of them (the most important, in my opinion). These are: 1) the impossibility to establish with certainty whether a patient got ill due to his lifestyle; 2) the lack of a feasible and reliable method of establishing an individual’s responsibility for his lifestyle; 3) a patient’s right to privacy; 4) some moral requirements and principles and, last but not least, 5) the ethics of the medical profession.

The principle of indifference states that in the absence of any relevant evidence, a rational agent will distribute their credence equally among all the possible outcomes under consideration. Despite its intuitive plausibility, PI famously falls prey to paradox, and so is widely rejected as a principle of ideal rationality. In this article, I present a novel rehabilitation of PI in terms of the epistemology of comparative confidence judgments. In particular, I consider two natural comparative reformulations of PI (...) and argue that while one of them prescribes the adoption of patently irrational epistemic states, the other provides a consistent formulation of PI that overcomes the most salient limitations of existing formulations.

I describe and motivate Rational Internalism, a principle concerning the relationship between motivating reasons (which explain actions) and normative reasons (which justify actions). I use this principle to construct a novel argument against Objectivist theories of normative reasons, which hold that facts about normative reasons can be analyzed in terms of an independently specified class of normative or evaluative facts. I then argue for an alternative theory of normative reasons, the Reasoning View, which is consistent with both Rational (...) Internalism and one standard motivation for Objectivism. (shrink)

This essay is about the relationship between the notions of practical reason, the will, and choice in Kant’s practical philosophy. Although Kant explicitly identifies practical reason and the will, many interpreters argue that he cannot really mean it on the grounds that unless they are distinct, irrational and, especially, immoral action is impossible. Other readers affirm his identification but distinguish the will from choice on the same basis. We argue that proper attention to Kant’s conception of practical reason as a (...) capacity reveals that these distinctions are neither textually grounded nor philosophically necessary. His moral psychology concerns a single capacity, practical reason, which is the will, and whose actualities in this or that individual fall under the title of choice. Practical reason is the will and choice because it is the rational faculty of desire: a rational being’s capacity to be, by means of her representations, the cause of the actuality of their objects. This, we argue, is entailed by his conception of rational action: action not just in accordance with, but in and through the representation of, principles. The possibility of irrational action is explained not by a distinction between capacities but by the finitude, and thereby the fallibility, of human reason. (shrink)

The objection from the insolvability of principle-based modal disagreements appears to support the claim that there are no objective modal facts, or at the very least modal facts cannot be accounted for by modal rationalist theories. An idea that resurfaced fairly recently in the literature is that the use of ordinary empirical statements presupposes some prior grasp of modal notions. If this is correct, then the idea that we may have a total agreement concerning empirical facts and disagree on (...) modal facts, which is the starting point of the objection from the insolvability of modal disagreement, is undercut. This paper examines the no-separation thesis and shows that some of the arguments against the classical (empiricist) distinction between empirical and modal statements fail to be conclusive if they are taken to defend a strong notion of metaphysical possibility. The no-separation thesis appears to work only in theoretical frameworks where metaphysical modalities are considered (broadly) conceptual. For these reasons, the no-separation thesis cannot save modal rationalism from the insolvability of modal disagreement. (shrink)

According to a well-known view in the philosophy of mind, intentional attitudes by their very nature satisfy requirements of rationality (e.g. Davidson 1980; Dennett 1987; Millar 2004). This view (which I shall call Constitutivism) features prominently as the ‘principle of minimal rationality’ in de Sousa’s monograph The Rationality of Emotion (1987). By explicating this principle in terms of the notion of the formal object of an attitude, de Sousa articulates an interesting and original version of (...) Constitutivism, which differs in important respects from other extant versions. In this paper, I explore this version of Constitutivism against the background of recent developments in the theory of rationality and make explicit its ramifications for the long-standing dispute over whether the mind is essentially normative. My focus will be on how to conceive of the form of the rationality requirements that attitudes as such must satisfy according to this principle. I argue that, although de Sousa seems officially to endorse a structuralist conception of rationality, according to which these requirements are requirements of coherence, his considerations on formal objects suggest that they are more aptly conceived in terms of a reasons-responsive conception of rationality. I further argue that which of these two readings we choose makes a significant difference to the prospect of vindicating the essential normativity of mind by invoking the principle of minimal rationality.

According to the Principle of Sufficient Reason, every fact has an explanation. An important challenge to this principle is that it risks being a counterexample to itself. What explains why everything needs to be explained? My first goal is to distinguish two broad kinds of answers to this question, which I call “Humean Rationalism” and “Non-Humean Rationalism”. My second goal will be to defend the prospects of Humean Rationalism.

In his famous 1982 paper, Allen Newell [22, 23] introduced the notion of knowledge level to indicate a level of analysis, and prediction, of the rational behavior of a cognitive arti cial agent. This analysis concerns the investigation about the availability of the agent knowledge, in order to pursue its own goals, and is based on the so-called Rationality Principle (an assumption according to which "an agent will use the knowledge it has of its environment to achieve its (...) goals" [22, p. 17]. By using the Newell's own words: "To treat a system at the knowledge level is to treat it as having some knowledge, some goals, and believing it will do whatever is within its power to attain its goals, in so far as its knowledge indicates" [22, p. 13]. In the last decades, the importance of the knowledge level has been historically and system- atically downsized by the research area in cognitive architectures (CAs), whose interests have been mainly focused on the analysis and the development of mechanisms and the processes governing human and (arti cial) cognition. The knowledge level in CAs, however, represents a crucial level of analysis for the development of such arti cial general systems and therefore deserves greater research attention [17]. In the following, we will discuss areas of broad agree- ment and outline the main problematic aspects that should be faced within a Common Model of Cognition [12]. Such aspects, departing from an analysis at the knowledge level, also clearly impact both lower (e.g. representational) and higher (e.g. social) levels. (shrink)

Many theorists have proposed that we can use the principle of indifference to defeat the inductive sceptic. But any such theorist must confront the objection that different ways of applying the principle of indifference lead to incompatible probability assignments. Huemer offers the explanatory priority proviso as a strategy for overcoming this objection. With this proposal, Huemer claims that we can defend induction in a way that is not question-begging against the sceptic. But in this article, I argue that (...) the opposite is true: if anything, Huemer’s use of the principle of indifference supports the rationality of inductive scepticism. (shrink)

If a proposition is typically true, given your evidence, then you should believe that proposition; or so I argue here. In particular, in this paper, I propose and defend a principle of rationality---call it the `Typical Principle'---which links rational belief to facts about what is typical. As I show, this principle avoids several problems that other, seemingly similar principles face. And as I show, in many cases, this principle implies the verdicts of the Principal (...) class='Hi'>Principle: so ultimately, the Typical Principle may be the more fundamental of the two. (shrink)

How should an agent decide what to do when she is uncertain not just about morally relevant empirical matters, like the consequences of some course of action, but about the basic principles of morality itself? This question has only recently been taken up in a systematic way by philosophers. Advocates of moral hedging claim that an agent should weigh the reasons put forward by each moral theory in which she has positive credence, considering both the likelihood that that theory is (...) true and the strength of the reasons it posits. The view that it is sometimes rational to hedge for one's moral uncertainties, however, has recently come under attack both from those who believe that an agent should always be guided by the dictates of the single moral theory she deems most probable and from those who believe that an agent's moral beliefs are simply irrelevant to what she ought to do. Among the many objections to hedging that have been pressed in the recent literature is the worry that there is no non-arbitrary way of making the intertheoretic comparisons of moral value necessary to aggregate the value assignments of rival moral theories into a single ranking of an agent's options. -/- This dissertation has two principal objectives: First, I argue that, contra these recent objections, an agent's moral beliefs and uncertainties are relevant to what she rationally ought to do, and more particularly, that agents are at least sometimes rationally required to hedge for their moral uncertainties. My principal argument for these claims appeals to the enkratic conception of rationality, according to which the requirements of practical rationality derive from an agent's beliefs about the objective, desire-independent value or choiceworthiness of her options. Second, I outline a new general theory of rational choice under moral uncertainty. Central to this theory is the idea of content-based aggregation, that the principles according to which an agent should compare and aggregate rival moral theories are grounded in the content of those theories themselves, including not only their value assignments but also the metaethical and other non-surface-level propositions that underlie, justify, or explain those value assignments.

Finite rational agents possess justified knowledge of necessary rational norms (NRNs), such as logical laws and principles of inference, despite their contingent cognitive capacities. This paper develops an exhaustive analytic trichotomy of non-theistic accounts of NRNs—mind-dependent, impersonal necessary, and brute—and argues that none can make such knowledge possible. Employing the Ontological Congruence Principle, each option is shown to render justification epistemically accidental. The resulting Rational Norms Dilemma Theorem establishes an impossibility claim: if non-theistic metaphysics is true, knowledge of NRNs (...) is impossible. The eliminative result yields a minimal positive residue, motivating Epistemic Revelation as a necessary condition for non-accidental epistemic access. This paper does not presuppose theism, appeal to causal interaction with abstract objects, or rely on grounding frameworks. (shrink)

According to epistemological disjunctivism (ED), in paradigmatic cases of perceptual knowledge, a subject, S, has perceptual knowledge that p in virtue of being in possession of reasons for her belief that p which are both factive and reflectively accessible to S. It has been argued that ED is better placed than both knowledge internalism and knowledge externalism to undercut underdetermination-based skepticism. I identify several principles that must be true if ED is to be uniquely placed to attain this goal. After (...) that, I use those principles to formulate a diachronic skeptical argument. This argument yields the counterintuitive conclusion that understanding a global skeptical hypothesis is all it takes for a rational subject to lose all her perceptual knowledge of the world. Next, I show that a popular Austinian move must reject one or another of the principles that underlie ED. I close by delineating a novel strategy that can block the diachronic skeptical argument while preserving all the principles. The key idea is that perceptual knowledge is grounded in primitive, perceptual and recognitional abilities. This view sheds new light on some puzzling features of global skepticism that have been noted by Descartes and Hume, among others. (shrink)

This paper presents a deductive argument from the existence of intelligible thought to the necessity of a rational moral order. Drawing on classical principles of logic, and arguing that intelligibility presupposes a non-contingent, coherent ground for existence. This existence, as ascribed through logical necessity, The necessary existence is shown to be rational, self existent, and morally good by definition. The second half of the paper begins building a metaphysical grounding into ethics, without committing an is-ought gap. I argue that moral (...) responsibility arises from self-perceptive rational agency. and that your misalignment with moral truth leads to natural consequences. This culminates in a moral argument not rooted in theological claims, but in epistemic and modal necessity, offering a non-theistic justification for objective morality. The argument is structured syllogistically to ensure logical clarity and make comment, critiques, or clarifications easier to make. Future work will expand on this foundation toward applied ethical themes such as mercy, deception, and justified authority. My aim is to establish a defensible, repeatable framework for reasoning around moral truth, rooted in rational necessity. (shrink)

The relations between rationality and optimization have been widely discussed in the wake of Herbert Simon's work, with the common conclusion that the rationality concept does not imply the optimization principle. The paper is partly concerned with adding evidence for this view, but its main, more challenging objective is to question the converse implication from optimization to rationality, which is accepted even by bounded rationality theorists. We discuss three topics in succession: (1) rationally defensible cyclical (...) choices, (2) the revealed preference theory of optimization, and (3) the infinite regress of optimization. We conclude that (1) and (2) provide evidence only for the weak thesis that rationality does not imply optimization. But (3) is seen to deliver a significant argument for the strong thesis that optimization does not imply rationality. (shrink)

This paper examines the philosophical foundations of Goethe’s morphological studies, in particular his concept of the ‘archetypal plant', which can be described as the dynamic principle of a living surface that governs plant formation through alternating processes of expansion and contraction. The Austrian philosopher Rudolf Steiner claimed that Goethe’s approach offers a scientifically grounded approach to understanding organic form and development through what may be termed empirically based, productive intellectual intuition, namely the mental reconstruction of an organism’s formative (...) class='Hi'>principle and laws. Here it is shown that Goethe’s rational organicism, as elaborated by Steiner, provides a conceptual and methodological framework that suggests a solution to the long-standing problem of understanding organismic properties like autopoiesis, autonomy and agency. Yet, Goethe struggled to identify a comparable principle for animals. Steiner argued that animal life is determined by a psychological principle—a non-physical centre of sensation and movement that structures the organism in relation to its environment—and that this, too, can be grasped in productive intuition. The paper reconstructs the animal archetype by delineating its essential features: the relations between its interior and exterior, realized in sensory, nutritive and motor functions. The study concludes that Goethe’s rational organicism can serve as a methodological complement to the organicism of the current philosophy of biology. (shrink)

ABSTRACT: Decision-theoretic approach and a nonlinguistic theory of norms are applied in the paper in an attempt to explain the nature of scientific rationality. It is considered as a normative system accepted by scientific community. When we say that a certain action is rational, we express a speaker’s acceptance of some norms concerning a definite action. Scientists can choose according to epistemic utility or other rules and values, which themselves have a variable nature. Rationality can be identified with (...) a decision to accept a norm. This type of decision cannot be reduced only to its linguistic formulation; it is an act of evolvement of the normative regulation of human behavior. Norms are treated as decisions of a normative authority: a specific scientific community is the normative authority in science. These norms form a system and they are absolutely objective in the context of individual scientists. There exists an invariant core in all the norms of rationality, accounting for their not being liable to change, as compared with the flexibility of legal norms. The acceptance of and abidance by these norms is of social importance – it affects the aims of the community. A norm only defines the common framework and principles of scientific problem-solving; its application is a matter of professional skills and creative approach to a particular problem. It is of no importance at all, if an agent’s cognitive abilities do not live up to the requirements of a norm. Such discrepancy can be compensated for by the fact that a scientist carries out work in a conceptual and normative framework established by a respective scientific community. (shrink)

Contractarians aim to derive moral principles from the dictates of instrumental rationality alone. But it is well-known that contractarian moral theories struggle to identify normative principles that are both uniquely rational and morally compelling. Michael Moehler's recent book, *Minimal Morality* seeks to avoid these difficulties by developing a novel "two-level" social contract theory, which restricts the scope of contractarian morality to cases of deep and persistent moral disagreement. Yet Moehler remains ambitious, arguing that a restricted version of Kant's categorical (...) imperative is a uniquely rational principle of conflict resolution. We develop a formal model of Moehler's informal game-theoretic argument, which reconstructs a valid argument for Moehler's conclusion. This model, in turn, enables us to expose how a successful argument for Moehler's contractarian principle rests on assumptions that can only be justified by subtle yet significant departures from the standard conception of rationality. We thus extend our understanding of familiar contractarian difficulties by showing how they arise even if we restrict the scope of contractarian morality to a domain where its application seems both promising and necessary. We show that the problem lies not in contractarians' immodest ambitions but in the modest resources rationality can offer to satisfy them. (shrink)

In this chapter, it is suggested that our epistemic access to metaphysical modality generally involves rationalist, a priori elements. However, these a priori elements are much more subtle than ‘traditional’ modal rationalism assumes. In fact, some might even question the ‘apriority’ of these elements, but I should stress that I consider a priori and a posteriori elements especially in our modal inquiry to be so deeply intertwined that it is not easy to tell them apart. Supposed metaphysically necessary identity statements (...) involving natural kind terms are a good example: the fact that empirical input is crucial in establishing their necessity has clouded the role and content of the a priori input, as I have previously argued. For instance, the supposed metaphysically necessary identity statement involving water and its microstructure can only be established with the help of a controversial a priori principle concerning the determination of chemical properties by microstructure. The Kripke-Putnam framework of modal epistemology fails precisely because it is unclear whether the required a priori element is present. My positive proposal builds on E. J. Lowe’s work. Lowe holds that our knowledge of metaphysical modality is based on our knowledge of essence. Lowe’s account strives to offer a uniform picture of modal epistemology: essence is the basis of all our modal knowledge. This is the basis of Lowe’s modal rationalism. I believe that Lowe’s proposal is on the right lines in the case of abstract objects, but I doubt that it can be successfully applied to the case of natural kinds. Accordingly, the case of natural kinds will be my main focus and I will suggest that modal rationalism, at least as it is traditionally understood, falls short of explaining modal knowledge concerning natural kinds. Yet, I think that Lowe has identified something of crucial importance for modal epistemology, namely the essentialist, a priori elements present in our modal inquiry. The upshot is that rather than moving all the way from modal rationalism to modal empiricism, a type of hybrid approach, ‘empirically-informed modal rationalism ’, can be developed. (shrink)

Some arguments include imperative clauses. For example: ‘Buy me a drink; you can’t buy me that drink unless you go to the bar; so, go to the bar!’ How should we build a logic that predicts which of these arguments are good? Because imperatives aren’t truth apt and so don’t stand in relations of truth preservation, this technical question gives rise to a foundational one: What would be the subject matter of this logic? I argue that declaratives are used to (...) produce beliefs, imperatives are used to produce intentions, and beliefs and intentions are subject to rational requirements. An argument will strike us as valid when anyone whose mental state satisfies the premises is rationally required to satisfy the conclusion. For example, the above argument reflects the principle that it is irrational not to intend what one takes to be the necessary means to one’s intended ends. I argue that all intuitively good patterns of imperative inference can be explained using off-the-shelf formulations of our rational requirements. I then develop a formal-semantic theory embodying this view that predicts a range of data, including free-choice effects and Ross’s paradox. The resulting theory shows one way that our aspirations to rational agency can be discerned in the patterns of our speech, and is a case study in how the philosophy of language and the philosophy of action can be mutually illuminating.

The Sure-Thing Principle famously appears in Savage’s axiomatization of Subjective Expected Utility. Yet Savage introduces it only as an informal, overarching dominance condition motivating his separability postulate P2 and his state-independence postulate P3. Once these axioms are introduced, by and large, he does not discuss the principle any more. In this note, we pick up the analysis of the Sure-Thing Principle where Savage left it. In particular, we show that each of P2 and P3 is equivalent to (...) a dominance condition; that they strengthen in different directions a common, basic dominance axiom; and that they can be explicitly combined in a unified dominance condition that is a candidate formal statement for the Sure-Thing Principle. Based on elementary proofs, our results shed light on some of the most fundamental properties of rational choice under uncertainty. In particular they imply, as corollaries, potential simplifications for Savage’s and the Anscombe- Aumann axiomatizations of Subjective Expected Utility. Most surprisingly perhaps, they reveal that in Savage’s axiomatization, P3 can be weakened to a natural strengthening of so-called Obvious Dominance. (shrink)

We often have affective responses to fictional events. We feel afraid for Desdemona when Othello approaches her in a murderous rage. We feel disgust toward Iago for orchestrating this tragic event. What mental architecture could explain these affective responses? In this paper I consider the claim that the best explanation of our affective responses to fiction involves imaginative desires. Some theorists argue that accounts that do not invoke imaginative desires imply that consumers of fiction have irrational desires. I argue that (...) there are serious worries about imaginative desires that warrant skepticism about the adequacy of the account. Moreover, it is quite difficult to articulate general principles of rationality for desires, and even according to the most plausible of these possible principles, desires about fiction are not irrational.
