"In the realm of ideas, of mental objects, those ideas whose
properties are reproducible are called mathematical objects,
and the study of mental objects with reproducible properties
is called mathematics."

Davis and Hersh
(The Mathematical Experience, 1981)
Mathematics is the science which draws necessary conclusions.
 Benjamin
Peirce
(Linear Associative Algebra, 1870)
The Reader may here observe the Force of Numbers, which can be successfully
applied, even to those things, which one would imagine are subject to no Rules.
There are very few things which we know, which are not capable of being reduced
to a Mathematical Reasoning; and when they cannot it's a sign our knowledge of
them is very small and confused; and when a Mathematical Reasoning can be had
it's as great a folly to make use of any other, as to grope for a thing in the
dark, when you have a Candle standing by you.

John Arbuthnot (Of the Laws of Chance, 1692)
The case for my life, then, or for
that of any one else who has been a mathematician in the same sense in
which I have been one, is this: that I have added something to
knowledge, and helped others to add more; and that these somethings
have a value which differs in degree only, and not in kind, from that
of the creations of the great mathematicians, or of any other artists,
great or small, who have left some kind of memorial behind them.
 G.H. Hardy
(A
Mathematician's Apology, 1940)
"What is now proved was once only imagin'd."
 William Blake

Marriage of Heaven and Hell, 1790)
