My goal in this paper is to show that Kant’s prohibition on certain kinds of knowledge of things-in-themselves is motivated less by his anti-soporific encounter with Hume than by his new view of the distinction between “real” and “logical” modality, a view that developed out of his reflection on the rationalist tradition in which he was trained. In brief: at some point in the 1770’s, Kant came to hold that a necessary condition on knowing a proposition is that one be able to prove that all the items it refers to are either really possible or really impossible. Most propositions about things-in-themselves, in turns out, cannot meet this condition. I conclude by suggesting that the best interpretation of this modal condition is as a kind of coherentist constraint.

Most accounts of Kant's epistemology focus narrowly on cognition and knowledge. Kant himself, however, thought that there are many other important species of assent : opinion, persuasion, conviction, belief, acceptance, and assent to the deliverances of common sense. ;My goal in this dissertation is to isolate and motivate the principles of rational acceptability which, for Kant, govern each of these kinds of assent, instead of focusing merely on cognition and knowledge. Some of the principles apply in the context of everyday assent-formation; others apply in more specific contexts. ;The project is worthwhile for at least two reasons. First, it highlights issues that are both neglected in the literature and yet crucial for understanding Kant's famous claims about the nature and limits of our epistemic access to appearances and things-in-themselves. ;Second, it lays out Kant's sophisticated and largely plausible account of our intellectual obligations and of the various roles that "subjective" considerations play in our practices of assent-formation. Kant charts a viable middle course between the epistemic abstemiousness of Cliffordian evidentialists and the epistemic excess of Jamesian pragmatists. ;I begin with an overview of Kant's pre-critical epistemology, and then provide a broad survey of the ethics of assent in the critical period, noting in particular the way Kant allows for exceptions to his First Principle---the principle that it is rational to assent to proposition only on the basis of sufficient objective grounds. Having sketched the whole picture, I turn to the principles governing knowledge and use a new account of Kant's concepts of objective and subjective justification to solve a perennial interpretive problem regarding the nature of our epistemic access to material objects. I go on to examine Kant's theory of belief ; my central claim there is that Kant is much more liberal regarding belief about things-in-themselves that is based on theoretical grounds than most commentators think. Finally, I consider a number of objections to my "Liberal" interpretation of Kant's ethics of assent, and conclude with a meditation on Kant's view of enlightenment.

Descartes's lack of clarity about the causal connections between brain states and mental states has led many commentators to conclude that he has no coherent account of body-mind relations in sensation, or that he was simply confused about the issue. In this paper I develop what I take to be a coherent account that was available to Descartes, and argue that there are both textual and systematic reasons to think that it was his considered view. The account has brain states serving as occasions for the mind to produce in itself the sensations that it takes these brain states to signify. The relation between body and mind on this model is thus neither a standard efficient-causal relation, nor an occasionalist one, but rather a semantic-causal relation (i.e. a non-standard efficient causal relation that goes by way of natural signification). At the end of the paper I argue that the model does not undermine Descartes' commitment to the self-transparency of the mind.

In the first part of the paper I reconstruct Kant’s proof of the existence of a ‘most real being’ while also highlighting the theory of modality that motivates Kant’s departure from Leibniz’s version of the proof. I go on to argue that it is precisely this departure that makes the being that falls out of the pre-critical proof look more like Spinoza’s extended natura naturans than an independent, personal creator-God. In the critical period, Kant seems to think that transcendental idealism allows him to avoid this conclusion, but in the last section of the paper I argue that there is still one important version of the Spinozistic threat that remains. -/-.

In this paper I explore Kant’s critical discussions of the topic of miracles (including the important but neglected fragment from the 1780s called “On Miracles”) in an effort to answer the question in the title. Along the way I discuss some of the different kinds of “laws” in Kant’s system, and also the argument for his claim that, even if empirical miracles do occur, we will never be in a good position to identify instances of them. I conclude with some tentative remarks about the notorious suggestion that intelligible finite agents, too, might have some sort of influence over the laws of nature. The goal throughout is to show that exploring Kant’s answer to a traditional question in philosophical theology can deepen our understanding of his metaphysics and epistemology of nature generally.

The “ ethics of belief” refers to a cluster of questions at the intersection of epistemology, philosophy of mind, psychology, and ethics. The central question in the debate is whether there are norms of some sort governing our habits of belief formation, belief maintenance, and belief relinquishment. Is it ever or always morally wrong to hold a belief on insufficient evidence? Is it ever or always morally right to believe on the basis of sufficient evidence, or to withhold belief in the perceived absence of it? Is it ever or always obligatory to seek out all available epistemic evidence for a belief? Are there some ways of obtaining evidence that are themselves immoral or imprudent? -/-

Kant's speculative theistic proof rests on a distinction between “logical” and “real” modality that he developed very early in the pre-critical period. The only way to explain facts about real possibility, according to Kant, is to appeal to the properties of a unique, necessary, and “most real” being. Here I reconstruct the proof in its historical context, focusing on the role played by the theory of modality both in motivating the argument (in the pre-critical period) and, ultimately, in undoing it as a source of knowledge of God's existence (in the critical period). Along the way I examine Kant's version of the now-popular “actualist” thesis that facts about what is possible must be explained by facts about what is actual. I conclude by discussing why the critical Kant claims both that there are rational grounds for accepting the conclusion of his theistic proof, and that such acceptance can not count as knowledge. This is important, I argue, because the same considerations ultimately motivate his prohibition on knowledge of things-in-themselves generally.

The Proper Functionist account of warrant – like many otherexternalist accounts – is vulnerable to certain Gettier-style counterexamples involving accidentally true beliefs. In this paper, I briefly survey the development of the account, noting the way it was altered in response to such counterexamples. I then argue that Alvin Plantinga's latest amendment to the account is flawed insofar as it rules out cases of true beliefs which do intuitively strike us as knowledge, and that a conjecture recently put forward by Thomas Crisp is also defective. I conclude by presenting my own suggestion as to how the account can be made less vulnerable to counterexamples involving accidentally true beliefs. Although I stay within the confines of Proper Functionism here, I think that my proposal (modulo a few details) could be attached to other externalist accounts of warrant as well.

This paper considers Kant's views on how it can be rational to hope for God's assistance in becoming morally good. If I am fully responsible for making myself good and can make myself good, then my moral condition depends entirely on me. However, if my moral condition depends entirely on me, then it cannot depend on God, and it is therefore impossible for God to provide me with any assistance. But if it is impossible for God to provide me with any assistance, it is irrational for me to hope for such assistance. I address this conundrum by providing an analysis of one necessary condition of rational hope: hope is rational only if the subject is not in a position to be certain that p is really impossible. I then offer several different strategies on which it might be rational to hope that God provides moral assistance, with the most radical of these strategies suggesting that, given our ignorance of the laws of the intelligible world, for all human beings know it is metaphysically possible that God perform a noumenal miracle on their moral character.

Kant holds that in order to have knowledge of an object, a subject must be able to “prove” that the object is really possible—i.e., prove that there is neither logical inconsistency nor “real repugnance” between its properties. This is (usually) easy to do with respect to empirical objects, but (usually) impossible to do with respect to particular things-in-themselves. In the first section of the paper I argue that an important predecessor of Kant’s account of our ignorance of real possibility can be found in Locke’s Essay Concerning Human Understanding. In the middle sections I discuss the way in which our inability to prove the real possibility of things-in-themselves motivates Kant’s famous prohibition on certain kinds of knowledge-claims about them. In the final section I examine Hegel’s attempts to dissolve this problem of real repugnance and thereby remove an inherited obstacle to speculative knowledge of the supersensible.

In the ‘Refutation of Idealism’ chapter of the first Critique, Kant argues that the conditions required for having certain kinds of mental episodes are sufficient to guarantee that there are ‘objects in space’ outside us. A perennially influential way of reading this compressed argument is as a kind of causal inference: in order for us to make justified judgements about the order of our inner states, those states must be caused by the successive states of objects in space outside us. Here I consider the best recent versions of this reading, and argue that each suffers from apparently fatal flaws.

The problem of infant suffering and death is often regarded as one of the more difficult versions of the problem of evil (see Ivan Karamazov), especially when one considers how God can be thought good to infant victims by the infant victims. In the first section of this paper, I examine two recent theodicies that aim to solve this problem but (I argue) fail. In the second section, I suggest that the only viable approach to the problem rejects the idea that the suffering of such unfortunates must be defeated by some greater good.

In this chapter I highlight the apparent tensions between Kant’s very stringent critique of metaphysical speculation in the “Discipline of Pure Reason” chapter and his endorsement of Belief (Glaube) and hope (Hoffnung) regarding metaphysical theses in the subsequent “Canon of Pure Reason.” In the process I will examine his distinction between the theoretical and the practical bases for holding a “theoretical” conclusion (i.e. a conclusion about “what exists” rather than “what ought to be”) and argue that the position is subtle but coherent. In the second part of the paper I focus on Kant’s account of rational hope in the Doctrine of Method: its nature, scope, conditions, and role in the philosophy of religion generally.

Eric Watkins and Marcus Willaschek provide a valuable service to people working on Kant’s epistemology and philosophy of mind by laying out a synoptic picture of Kant’s view of theoretical cognition. Their picture incorporates admirably clear accounts of the familiar building blocks of cognition—sensation, intuition, concept, and judgment—as well as some innovative interpretive theses of their own. Watkins and Willaschek’s basic claim is that, for Kant, theoretical cognition is “a mental state [or “representation”] that determines a given object by attributing general features to it”. So Watkins and Willaschek view Kantian cognition fundamentally as a mental state of...
