The one-world interpretation of Kant's idealism holds that appearances and things in themselves are, in some sense, the same things. Yet this reading faces a number of problems, all arising from the different features Kant seems to assign to appearances and things in themselves. I propose a new way of understanding the appearance/thing in itself distinction via an Aristotelian notion that I call, following Kit Fine, a ‘qua-object.’ Understanding appearances and things in themselves as qua-objects provides a clear sense in which they can be the same things while differing in many of their features

I argue that Schopenhauer’s views on the foundations of morality challenge the widely-held belief that moral realism requires cognitivism about moral judgments. Schopenhauer’s core metaethical view consists of two claims: that moral worth is attributed to actions based in compassion, and that compassion, in contrast to egoism, arises from deep metaphysical insight into the non-distinctness of beings. These claims, I argue, are sufficient for moral realism, but are compatible with either cognitivism or non-cognitivism. While Schopenhauer’s views of moral judgment are not obviously consistent, I show how various passages suggest a form of non-cognitivism. This non-cognitivism, I claim, is compatible with moral realism.

Kant's theoretical philosophy is often read as a response to skeptical challenges raised by his predecessors. Yet Kant himself explicitly discusses skepticism in relatively few places in his published work, so Michael Forster's focused examination of Kant's relation to skepticism is a useful addition to the literature. Forster sets out to distinguish different types of skepticism to which Kant might be responding, determine what responses Kant offers, and evaluate the strength of those responses.Perhaps the most valuable part of the book is the opening chapters, where Forster distinguishes three kinds of skepticism about metaphysics, and argues that it is a mistake to see Cartesian, veil of perception skepticism as a central target of Kant's. Though this point has been made before, insufficient attention to it has continued to result in misplaced criticisms of Kant's project, and Forster's forceful reminder is certainly welcome.The other two types of skepticism, Forster argues, did play crucial roles in the development of Kant's metaphysical views, with each at some point rousing Kant from a self-described "dogmatic slumber." Forster claims that the 1766.

Kant's philosophy promises to explain various synthetic a priori claims. Yet, as several of his commentators have noted, it is hard to see how these explanations could work unless they themselves rested on unexplained synthetic a priori claims. Since Kant appears to demand explanations for all synthetic a priori claims, it would seem that his project fails on its own terms. I argue, however, that Kant holds that explanations are required only for synthetic a priori claims about (purportedly) experience-independent entities, and that his project rests on a rationalist method of reflection that justifies certain basic synthetic a priori claims.
