When one considers one's own persistence over time from the first-person perspective, it seems as if facts about one's persistence are "further facts," over and above facts about physical and psychological continuity. But the idea that facts about one's persistence are further facts is objectionable on independent theoretical grounds: it conflicts with physicalism and requires us to posit hidden facts about our persistence. This essay shows how to resolve this conflict using the idea that imagining from the first-person point of view is a guide to centered possibility, a type of possibility analyzed in terms of centered worlds.

This essay defends a strong version of the Humean theory of motivation on which desire is necessary both for motivation and for reasoning that changes our desires. Those who hold that moral judgments are beliefs with intrinsic motivational force need to oppose this view, and many of them have proposed counterexamples to it. Using a novel account of desire, this essay handles the proposed counterexamples in a way that shows the superiority of the Humean theory. The essay addresses the classic objection that the Humean theory cannot explain the feeling of obligation, Stephen Darwall's example of motivationally potent reasoning that is not based on preexisting desires, Thomas Scanlon's criticism that the Humean theory fails to account for the structure and phenomenology of deliberation, and the phenomenon of akrasia as discussed by John Searle. In each case a Humean account explains the data at least as thoroughly as opposing views can, while fitting within a simpler total account of how we deliberate and act.

A central doctrine of Kant's Critique of Pure Reason holds that the content of human experience is rooted in an affection of sensibility by unknowable things in themselves. This famous and puzzling affection doctrine raises two seemingly intractable old problems, which can be termed the Indispensability and the Consistency Problems. By what right does Kant present affection by supersensible entities as an indispensable requirement of experience? And how could any argument for such indispensability avoid violating the Critique's doctrine of noumenal ignorance? This essay develops a new solution to both problems, setting out from the continuity between Kant's early and mature views on sensibility and mind-world relations. Kant's early writings subscribe to an interactionist cosmology opposed to both Leibniz's preestablished harmony and Malebranche's occasionalism. The modern debate on mind-world relations shaping Kant's early cosmology points us to a widely recognized motivation for interactionism, turning on a constraint on agency within certain noninteractionist cosmologies. In particular, Kant's early conversion to a libertarian theory of freedom, together with his rejection of occasionalism, provides the basis for a compelling argument for the indispensability of world-mind affection relations. Extended to the transcendental idealist framework, the same argument reveals noumenal affection as an indispensable presupposition of some knowledge claims consistently upheld by Kant. This leads in turn to a satisfying solution to the Consistency Problem, showing that the doctrine of noumenal affection is not merely consistent with, but is partly motivated by, Kant's commitment to noumenal ignorance.
