Here I propose to undertake a brief survey of the statements of the argument given by these proponents, formulating and qualifying as I go what seems to me a sound version of it, capable of withstanding both Ayer's criticism and others that I have developed. There must be additional ways in which the same or similar points can be expressed. Another review of Kant, Paton, Taylor, and Kenner would no doubt produce a somewhat different result. All that is claimed here (...) is that the argument advanced in this paper is sound and that it was suggested by certain statements of theirs. (shrink)
