The last function of reason is to recognize that there are an infinity of things which surpass it. – Blaise Pascal, Pensées, 1670
Logic is a large drawer, containing some useful instruments, and many more that are superfluous. A wise man will look into it for two purposes, to avail himself of those instruments that are really useful, and to admire the ingenuity with which those that are not so, are assorted and arranged. – Charles Caleb Colton, Lacon
