The view that analytic propositions are those which are true in virtue of rules of use is basically correct. But there are many kinds of rules of use, and rules of some of these kinds do not generate truth. There is nothing like a grammatical analytic, though grammatical rules are rules of use. So, this rules-of-use view falls short of being an explanatory account. My problem is to find what it is that is special about those rules of use which (...) do generate truth. I shall argue that they are distinguished from others by their purpose rather than their content. Given their special purpose, one can explain how they generate truth. It will follow that linguistic regularities, considered apart from the purposes of those who use language, fail to provide a basis for understanding analyticity. On my account of it, analyticity turns out to be a less important characteristic of propositions than necessity. This is be- cause necessity, unlike analyticity, has its roots, not just in a contemporary system of usage, but in a wide family of systems of belief and usage. My efforts to deflate the philosophical value of the analytic will be summed up in the conclusion that analytic propositions can be contingent. I think this conclusion is behind the feeling that the propositions of logic and arithmetic are not merely analytic. For, if they were merely analytic, that is, true only in virtue of transitory conventions, then they would be contingent. Justice can be done to this feeling by the view that they are both analytic and necessary. (shrink)

Attention to the conversational role of alethic terms seems to dominate, and even sometimes exhaust, many contemporary analyses of the nature of truth. Yet, because truth plays a role in judgment and assertion regardless of whether alethic terms are expressly used, such analyses cannot be comprehensive or fully adequate. A more general analysis of the nature of truth is therefore required – one which continues to explain the significance of truth independently of the role alethic terms play in discourse. We (...) undertake such an analysis in this paper; in particular, we start with certain elements from Kant and Frege, and develop a construct of truth as a normative modality of cognitive acts (e.g., thought, judgment, assertion). Using the various biconditional T-schemas to sanction the general passage from assertions to (equivalent) assertions of truth, we then suggest that an illocutionary analysis of truth can contribute to its locutionary analysis as well, including the analysis of diverse constructions involving alethic terms that have been largely overlooked in the philosophical literature. Finally, we briefly indicate the importance of distinguishing between alethic and epistemic modalities. (shrink)

This paper argues that there are true synthetic modal claims and that modal questions in philosophy are to be interpreted not in terms of logical necessity but in terms of synthetic necessity. I begin by sketching the debate about modality between logical empiricism and phenome-nology. Logical empiricism taught us to equate analyticity and neces-sity. The now common view is that analytic statements are necessary in the narrow sense but that there is also necessity in a wider sense. I argue against (...) this that we should distinguish analyticity and necessity more strictly. (shrink)

Materialists who do not deny the existence of mental phenomena usually claim that the mental supervenes on the physical, i.e. that there cannot be a change in the mental life of a man without there being a change in the man's body. This modal claim is usually understood in terms of logical necessity. I argue that this is a mistake, resulting from assumptions inherited from logical empiricism, and that it should be understood in terms of synthetic necessity.
