Logic is not concerned with human behavior in the same sense that physiology, psychology, and social sciences are concerned with i...t. These sciences formulate laws or universal statements which have as their subject matter human activities as processes in time. Logic, on the contrary, is concerned with relations between factual sentences (or thoughts). If logic ever discusses the truth of factual sentences it does so only conditionally, somewhat as follows: if such-and-such a sentence is true, then such-and-such another sentence is true. Logic itself does not decide whether the first sentence is true, but surrenders that question to one or the other of the empirical sciences.LESSATTRIBUTION DETAIL »

Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo pro...blems.LESSATTRIBUTION DETAIL »
The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliber...ate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.LESSATTRIBUTION DETAIL »
