Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims.

Based on an analysis of Kant's texts, I argue that:

(a) according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans cannot have experience.

(b) Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric.

Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning.

Quine's well-known ‘Two Dogmas of Empiricism’ (1951) plays a key role in the debate about the analytic-synthetic distinction. Taking to task the ideas of Carnap in particular, Quine shows that logical positivism works with a concept of scientific rationality that is based dogmatically on, among other things, the opposition analytic-synthetic.

Quine correctly argues that Carnap's distinction between internal and external questions rests on a distinction between analytic and synthetic, which Quine rejects. I argue that Quine needs something like Carnap's distinction to enable him to explain the obviousness of elementary mathematics, while at the same time continuing to maintain as he does that the ultimate ground for holding mathematics to be a body of truths lies in the contribution that mathematics makes to our overall scientific theory of the world. Quine's arguments against the analytic/synthetic distinction, even if fully accepted, still leave room for a notion of pragmatic analyticity sufficient for the indicated purpose.

According to Kant's most important definition an analytic judgement obtains when the predicate of a judgement is already contained intensionally in the subject. It has been objected (most recently by Robert Hanna) that whereas this containment is a sufficient criterion, nevertheless there are analytic judgements that do not have a corresponding conceptual content . In these cases one needs to add an extensional criterion. The chief goal of this essay is to examine this argument critically and to reject it on the grounds that although an analytic judgement can be defined extensionally, this does not achieve anything more than a conventional intensional definition. To this end Kant's argumentation on intension and extension will be reconstructed and this distinction will then be set in relation to the distinction between analytic and synthetic propositions. This discussion requires especially a clarification of the role of modality.

I present an argument for an interpretation of Kant's views on the nature of the ‘content [Inhalt]’ of ‘cognition [Erkenntnis]’. In contrast to one of the longest standing interpretations of Kant's views on cognitive content, which ascribes to Kant a straightforwardly psychologistic understanding of content, and in contrast as well to the more recently influential reading of Kant put forward by McDowell and others, according to which Kant embraces a version of Russellianism, I argue that Kant's views on this topic are of a much more Fregean bent than has traditionally been admitted or appreciated. I conclude by providing a sketch of how a better grasp of Kant's views on cognitive content in general can help bring into sharper relief what is, and what is not, at stake in the recent debates over whether Kant accepts a particular kind of cognitive content—namely, non-conceptual content.

1. Lewis White Beck describes Kant as engaging in a ‘two-front war’ against the rationalists and empiricists in an attempt to solve the problems of epistemology. Both groups, according to Kant, were mistaken in believing that there is but one ultimate source or faculty of knowledge. Discuss critically Kant’s attack on these two positions with particular reference to the distinction between analytic and synthetic judgements and Kant’s notion of synthetic a priori judgements. To what extent do you think that the distinction between these three kinds of judgements is valid? In your response you should refer to the arguments by Quine (‘Two Dogmas of Empiricism’) and Strawson/Grice.

This paper concentrates on some aspects of the history of the analytic-synthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, that is, within the Classical Model of Science: scientific knowledge as cognitio ex principiis . But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them.
