The best result of mathematics is to be able to do without it.

We do not dwell in the Palace of Truth. But, as was mentioned to me not long since, "There is a time coming when all things shall be found out." I am not so sanguine myself, believing that the well in which Truth is said to reside is really a bottomless pit.

Mathematics is of two kinds, Rigorous and Physical. The former is Narrow: the latter Bold and Broad. To have to stop to formulate rigorous demonstrations would put a stop to most physico-mathematical inquiries. Am I to refuse to eat because I do not fully understand the mechanism of digestion?

Shall I refuse my dinner because I do not fully understand the process of digestion?

Theory is the essence of facts. Without theory scientific knowledge would be only worthy of the madhouse.

Logic can be patient, for it is eternal.
