I just found out there is something called Wikiquote. I have a large collection of my favorite quotes so this is very interesting.

Wikiquote - Charles Darwin

On the Origin of Species (1859)
As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.
-- Charles Darwin

Wikiquote - Richard Feynman

"We scientists are clever — too clever — are you not satisfied? Is four square miles in one bomb not enough? Men are still thinking. Just tell us how big you want it!"
-- Richard Feynman

Wikiquote - Atheism
