ABSTRACT. Frege notes that in the case of a concept we can call the unsaturatedness its predictive nature. Quine writes that we can simplify grammar and logic by minimizing the number of our grammatical categories and ma-ximizing their size. Davidson follows Quine in refusing to accept a distinction between statements that are true in virtue of their meaning and statements which are true in virtue of the world. Putnam believes that there are analytic truths, if by an analytic truth one means a statement which is reducible to something like principles of elementary logic via meaning relations.
