Precisely what makes a proposition analytic? Numerous definitions of "analytic" have been advanced, of which we shall mention the two principal ones. (Each of them has variations.) The designation of the term "analytic" is different in these two definitions, though the denotation of the term is very nearly the same-that is to say, a proposition that is analytic by one definition will also be by the other, with certain exceptions, which we shall notice in due course.
