Henry Allison examines the central tenets of Hume's epistemology and cognitive psychology, as contained in the Treatise of Human Nature. Allison takes a distinctive two-level approach. On the one hand, he considers Hume's thought in its own terms and historical context. So considered, Hume is viewed as a naturalist, whose project in the first three parts of the first book of the Treatise is to provide an account of the operation of the understanding in which reason is subordinated to custom and other non-rational propensities. Scepticism arises in the fourth part as a form of metascepticism, directed not against first-order beliefs, but against philosophical attempts to ground these beliefs in the "space of reasons." On the other hand, Allison provides a critique of these tenets from a Kantian perspective. This involves a comparison of the two thinkers on a range of issues, including space and time, causation, existence, induction, and the self. In each case, the issue is seen to turn on a contrast between their underlying models of cognition. Hume is committed to a version of the perceptual model, according to which the paradigm of knowledge is a seeing with the "mind's eye" of the relation between mental contents. By contrast, Kant appeals to a discursive model in which the fundamental cognitive act is judgment, understood as the application of concepts to sensory data, Whereas regarded from the first point of view, Hume's account is deemed a major philosophical achievement, seen from the second it suffers from a failure to develop an adequate account of concepts and judgment.

The Evident Connexion presents a bold new reading of David Hume's famous 'bundle' theory of the self or mind, and his later rejection of it. Galen Strawson illuminates the 'uniting principle' of Hume's philosophy and argues that the bundle theory does not, as widely supposed, claim that there are no subjects of experience.

In the first ever book-length treatment of David Hume's philosophy of action, Constantine Sandis brings together seemingly disparate aspects of Hume's work to present an understanding of human action that is much richer than previously assumed. Sandis showcases Hume's interconnected views on action and its causes by situating them within a wider vision of our human understanding of personal identity, causation, freedom, historical explanation, and morality. In so doing, he also relates key aspects of the emerging picture to contemporary concerns within the philosophy of action and moral psychology, including debates between Humeans and anti-Humeans about both 'motivating' and 'normative' reasons. Character and Causation takes the form of a series of essays which collectively argue that Hume's overall project proceeds by way of a soft conceptual revisionism that emerges from his Copy Principle. This involves re-calibrating our philosophical ideas of all that agency involves to fit a scheme that more readily matches the range of impressions that human beings actually have. On such a reading, once we rid ourselves of a certain kind of metaphysical ambition we are left with a perfectly adequate account of how it is that people can act in character, freely, and for good reasons. The resulting picture is one that both unifies Hume's practical and theoretical philosophy and radically transforms contemporary philosophy of action for the better.

Kenneth R. Westphal presents an original interpretation of Hume's and Kant's moral philosophies, the differences between which are prominent in current philosophical accounts. Westphal argues that focussing on these differences, however, occludes a decisive, shared achievement: a distinctive constructivist method to identify basic moral principles and to justify their strict objectivity, without invoking moral realism nor moral anti-realism or irrealism. Their constructivism is based on Hume's key insight that 'though the laws of justice are artificial, they are not arbitrary'. Arbitrariness in basic moral principles is avoided by starting with fundamental problems of social coördination which concern outward behaviour and physiological needs; basic principles of justice are artificial because solving those problems does not require appeal to moral realism (nor to moral anti-realism). Instead, moral cognitivism is preserved by identifying sufficient justifying reasons, which can be addressed to all parties, for the minimum sufficient legitimate principles and institutions required to provide and protect basic forms of social coördination (including verbal behaviour). Hume first develops this kind of constructivism for basic property rights and for government. Kant greatly refines Hume's construction of justice within his 'metaphysical principles of justice', whilst preserving the core model of Hume's innovative constructivism. Hume's and Kant's constructivism avoids the conventionalist and relativist tendencies latent if not explicit in contemporary forms of moral constructivism.

Examines the development of Hume's ideas and their relation to eighteenth-century theories of the imagination and passions.

It is widely held that Hume's Treatise has little or nothing to do with problems of religion. Contrary to this view, Paul Russell argues that it is irreligious aims and objectives that are fundamental to the Treatise and account for its underlying unity and coherence
