IN delivering this lecture I am to speak on some aspect of truth. The practice of examining the various contexts in which a word may be used, in order to disclose what its usages have in common as a clue to its meaning, is of respectable antiquity. If I indulge this practice I find an “embarras de richesse” in modern philosophical literature under two headings, the truth of analytic propositions and the truth of synthetic propositions: the first deals with criteria (...) of consistency and the second with criteria of verifiability.
