One of the attractions of the Humean instrumentalist theory of practical rationality is that it appears to offer a special connection between an agent's reasons and her motivation. The assumption that Humeanism is able to assert a strong connection between reason and motivation has been challenged, most notably by Christine Korsgaard. She argues that Humeanism is not special in the connection it allows to motivation. On the contrary, Humean theories of practical rationality do connect reasons and motivation in a unique (...) and attractive way, though the nature of this connection has sometimes been misunderstood by both defenders and detractors of the theory.

David Hume is famous as a sceptical philosopher but the nature of his scepticism is difficult to pin down. Hume's True Scepticism provides the first sustained interpretation of Part 4 of Book 1 of Hume's Treatise: his deepest engagement with sceptical arguments, in which he notes that, while reason shows that we ought not to believe the verdicts of reason or the senses, we do so nonetheless. Donald C. Ainslie addresses Hume's theory of representation; his criticisms of Locke, Descartes, (...) and other predecessors; his account of the imagination; his understanding of perceptions and sensory belief; and his bundle theory of the mind and his later rejection of it.

In the Treatise of Human Nature , Hume argues that, because we have adequate ideas of the smallest parts of space, we can infer that space itself must conform to our representations of it. The paper examines two challenges to this argument based on Descartes's and Locke's treatments of adequate ideas, ideas that fully capture the objects they represent. The first challenge, posed by Arnauld in his Objections to the Meditations , asks how we can know that an idea is (...) adequate. The second challenge, implicit in Locke's Essay , asks how an empiricist can characterize an idea as inadequate, as both picking out an object and yet failing to capture it fully. In showing how Hume responds to these challenges, his theory of perceptual representation is explained and his treatment of space is related to his scepticism. His conclusion is shown not to be a characterization of space as it exists wholly apart from our powers of conception. Instead, in an adumbration of Kant, his claim is restricted to space as it appears to us. (shrink)

In lieu of an abstract, here is a brief excerpt of the content: Reviewed by Sextus, Montaigne, Hume: Pyrrhonizers by Brian C. Ribeiro Donald C. Ainslie Brian C. Ribeiro. Sextus, Montaigne, Hume: Pyrrhonizers. Brill: Leiden, 2021. Pp. 165. Hardback, $154.00. Brian C. Ribeiro’s Sextus, Montaigne, Hume: Pyrrhonizers is a charming and quirky investigation of his three titular skeptics. It is perhaps best understood as a skeptical investigation of skepticism. By that I mean that, like a good Pyrrhonist, Ribeiro explains (...) how things appear to him without claiming to lay down a doctrine or dogma. His topic is how and why skepticism still matters (7). And he suggests that those who are moved by skeptical arguments can learn intellectual modesty from them and thereby achieve a degree of philosophical “calmness of soul” (141).Ribeiro approaches his three figures by taking the cogency of their skeptical arguments for granted. There is little investigation of why these philosophers call various beliefs into question, and his concern is rather what remains once the skeptical doubts are taken on board. Because what he calls “Pyrrhonizing” philosophers reveal that large swaths of our beliefs lack epistemic merit, they also show us how we are not fully rational creatures in our everyday lives. In the case of Sextus, Ribeiro’s focus is on the famous question of whether skeptics can live their skepticism once they have actually suspended all belief. With Sextus, as with Montaigne and Hume, Ribeiro opts for the more radical of the interpretive options; he is not persuaded by Michael Frede’s suggestion that Pyrrhonists restrict their suspension only to abstruse matters, not the everyday (51). But even if we follow the “four-fold way” (20–23) that Sextus offers us as guides for life—the directives of nature, feelings, custom, and expertise—Ribeiro still thinks we will inevitably fall back into belief. He concludes that the original Pyrrhonists should be read aspirationally: insofar as we develop our capacities [End Page 517] to argue on both sides of every question and thus are able to suspend judgment, to that extent we will achieve tranquility. In the case of Montaigne, Ribeiro focuses on his Christian fideism. Once he recognizes the incapacity of reason to resolve intellectual problems, he falls back on faith. And Ribeiro argues that the Catholic flavor of this faith is simply a reflection of Montaigne’s surroundings. In a different community, he could just as easily have embraced a different faith. The heart of the book concerns Hume, whom Ribeiro discusses in three chapters, as opposed to the one each devoted to Sextus and Montaigne. In keeping with his interpretive preferences, Ribeiro’s Hume is a radical skeptic, though he acknowledges the significant yet “utterly perplexing” (95n22) naturalist strains that are also present. Ribeiro takes the resulting tension to be insoluble (98), though I was not convinced. Consider that, in both the Treatise and the Enquiry, Hume uses causal reasoning to investigate causal reasoning. He learns that our ideas are caused by prior impressions; that repeated experience of conjoint events causes us to associate our ideas of similar events; and so on. In the Treatise, he concludes the argument that association is at the root of such causal reasoning by presenting a set of rules, a “logic,” for it. The argument is not as such skeptical, though when Hume “recasts” it in the first Enquiry, he does so in terms of “sceptical doubts” and a “sceptical solution.” In the Treatise, “total” and “extravagant” skepticism come into play only as “systems of philosophy” that Hume uses to shed light on his own core commitments. The problem, I think, is that Ribeiro tends to read Hume a little too literally, as if he is himself falling prey to the skeptical upheaval of the conclusion to the first book of the Treatise, or the final section of the first Enquiry. But I would suggest that Hume is rather deploying the rhetoric of skepticism in these discussions, using it for his ultimate philosophical ends (a point that is especially clear in Ribeiro’s favorite of Hume’s works, the Dialogues). He is showing his reader how his naturalistic philosophical project is itself rooted in human nature, and thus does not yield insight into the intrinsic structure of... (shrink)

The article presents a new interpretation of Hume’s treatment of personal identity, and his later rejection of it in the “Appendix” to the Treatise. Hume’s project, on this interpretation, is to explain beliefs about persons that arise primarily within philosophical projects, not in everyday life. The belief in the identity and simplicity of the mind as a bundle of perceptions is an abstruse belief, not one held by the “vulgar” who rarely turn their minds on themselves so as to think (...) of their perceptions. The author suggests that it is this philosophical observation of the mind that creates the problems that Hume finally acknowledges in the “Appendix.” He is unable to explain why we believe that the perceptions by means of which we observe our minds while philosophizing are themselves part of our minds. This suggestion is then tested against seven criteria that any interpretation of the “Appendix” must meet. (shrink)

In 'The Moral Problem', Michael Smith defends a conception of normative reasons that is nonrelative. Given his understanding of normative reasons, nonrelativity commits him to the convergence hypothesis: that, as a result of the process or correction of beliefs and rational deliberation, 'all' agents would converge on having the same set of desires. I develop several reasons for being pessimistic about the truth of this hypothesis. As a result, if normative reasons exist, we have a reason to be skeptical of (...) either Smith's understanding of what normative reasons are or of his insistence that they are nonrelative. (shrink)

A well-known relativistic action at a distance interaction of two unequal masses is altered so as to yield purely Newtonian radial forces with fixed particle rest masses in the system center-of-momentum inertial frame. Although particle masses experience no kinematic mass increase in this frame, speeds are naturally restricted to less than the speed of light. We derive a relation between the center-of-momentum frame total Newtonian energy and the composite rest mass. In a new proper time quantum formalism, we obtain an (...) L2(R4 ⊗ R4, C) Hilbert space by varying individual particle rest masses. We propose the use of density operators, recognizing that the auxiliary proper time parameter is not an observable. The quantum formalism is applied to our altered version of the relativistic harmonic oscillator. Our generalized coherent states yield four-dimensional wave packets which follow the correct classical world lines. Appendices contain reviews of classical Hamiltonian reparametrization (incorporating our notion of manifest covariance), and a comparison of this work with the literature. (shrink)

Modern consequentialism is a very broad theory. Consequentialists can invoke a distribution sensitive theory of value to address the issues of distributive justice that bedeviled utilitarianism. They can attach intrinsic moral value to such acts truth-telling and promise-keeping and, so, acknowledge the essential moral significance of such acts in a way that classical utilitarianism could not. It can appear that there are no limits to consequentialism’s ability to respond to the criticisms against utilitarian theories by embracing a sophisticated theory of (...) value. But there are limits. They are imposed by consequentialism’s commitment to ground considerations of rightness solely on considerations of goodness. Some consequentialists have attempted to incorporate elements of guilt and desert into the theory of value. This can be done, consistent with consequentialist scruples, only if these notions can be analyzed without appeal to deontic concepts such as right and wrong. I analyze the problem consequentialists face and suggest a way incorporate notions of guilt and desert in a theory of value without relying in any fundamental way on concepts of right and wrong action.

This article explains Aquinas's attempt to show, within an Aristotelian framework, how the soul can be both a substance in its own right and the form of the body. I argue that although Aquinas' theory is logically consistent, its plausibility is weakened by the fact that it requires a significant modification of the Aristotelian conceptions of both substance and form.

This textbook is a flexible and affordable collection of classic and contemporary primary sources in philosophy. The readings cover seven basic topics of Western Philosophy. The selections are long enough to present a self-contained argument but not so lengthy that students lose track of the main point. The book includes a glossary and an appendix on logic and argumentation.

This book takes a novel look at the topics of school mathematics--arithmetic, geometry, algebra, and calculus. In this stroll on the mathematical seashore we hope to find, quoting Newton, "...a smoother pebble or a prettier shell than ordinary..." This book assembles a collection of mathematical pebbles that are not only curious but also important.

I owe thanks to Annemarie Butler, Jonathan Cottrell, and Barry Stroud for their thoughtful criticism of my interpretation in Hume's True Scepticism of David Hume's epistemology and philosophy of mind as presented in A Treatise of Human Nature.1 Butler focuses on my account of the mental mechanisms Hume provides for our everyday beliefs about external objects. She also challenges my appeal to what Hume calls "secondary" ideas in my explanation of Humean introspection. Cottrell raises questions about my interpretation of perceptions (...) generally, both introspective and non-introspective, as well as my understanding of Hume's conflicted statements about...

As biological and moral creatures, humans contain physical and psychological needs that correspond to various development stages. According to Lee, a hierarchy of biological and individual needs provides an objective basis for ethics. The anthropocentric hierarchy of needs provides a model for examining the needs of the environment as well. A sound world order must be based on an ethical theory that integrates the needs of humans and the environment of which they are a part. Political and economic systems must (...) universally address all needs at all levels. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Scepticism About Persons in Book II of Hume’s TreatiseDonald C. AinslieBook ii of Hume’s Treatise—especially its first two Parts on the “indirect passions” of pride, humility, love, and hatred—has mystified many of its interpreters.1 Hume clearly thinks these passions are important: Not only does he devote more space to them than to his treatment of causation, but in the “Abstract” to the Treatise, he tells us that Book II (...) “contains opinions that are altogether as new and extraordinary” (T 659) as those found in Book I. And, he says, these opinions constitute “the foundation” (T 646) for his treatment of morals and politics in Book III.2 The mystery arises, however, because in the actual text of [End Page 469] Book II Hume never spells out what makes his opinions on the passions “new and extraordinary,” nor why they are foundational for his moral theory.Thus some of his interpreters, notably Norman Kemp Smith, conclude that Hume was simply mistaken in his assessment of his treatment of the passions. While his accounts of the will and of motivation (in the early Sections of Part iii of Book II) are significant, Kemp Smith takes the extended analysis of the indirect passions to spring merely from his misplaced enthusiasm for associationist psychology. As such, the philosophical lessons to be learned from the first two Parts of Book II are slim.3 Páll Árdal, in contrast, tries to construct for Hume what he seems to have omitted—a philosophical rationale for his obvious interest in the indirect passions. Árdal starts by drawing attention to the role these passions play in Hume’s moral philosophy, in particular, his repeatedly connecting the indirect passions to the moral sentiments of approval and disapproval. Árdal concludes that Hume means to equate the moral sentiments with particular kinds of indirect passions. The first two Parts of Book II are of interest, on Ardal’s reading, because it is there that he shows us how moral sentimentalism can be founded on something more fully naturalistic than Hutcheson’s somewhat mysterious “moral sense.”4I argue against Árdal’s interpretation in §2. But this reopens the problem of accounting for Hume’s interest in the indirect passions. I offer my view in §§3–5 where, like Árdal, I provide a reconstruction of Hume’s discussion of these passions in order to show how it has an underlying philosophical motivation. My claim is that Hume relies on the indirect passions to explain how we form beliefs about persons as bearers of features that make them into who [End Page 470] they are. It is by feeling an indirect passion towards someone that we think of her as more than accidentally related to some quality, such as her country, her riches, her family, or even her character traits. In support of my interpretation I point to the many parallels Hume draws between the indirect passions and the associative mechanism he offers to explain our forming causal beliefs (I.iii). And I suggest that, just as Hume’s associative explanation of causal beliefs is necessitated by his scepticism about intrinsic “necessary connexions,” so also his associative mechanism for our beliefs about persons—the indirect passions—is necessitated by a certain kind of scepticism about persons. This is not the scepticism about persons that we find in “Of personal identity” (I.iv.6), where Hume argues against the view that our perceptions inhere in a simple soul; it is rather a scepticism about there being intrinsic features of persons that define them as who they are.But, before I explain in more detail what my claim amounts to, it will help to have available a brief description of the mechanism that Hume’s takes to explain the indirect passions.1. THE MECHANISM FOR THE INDIRECT PASSIONSA passion, for Hume, is a simple impression felt in response to various circumstances. Because of their simplicity, we cannot define passions by putting their characteristic feeling into words; instead, Hume thinks, we can only delineate “such circumstances, as attend them” (T 277). Passions are indirect if those circumstances include as an outcome the focusing of attention onto a person... (shrink)
