Quote by Francis Crick

"The Astonishing Hypothesis is that 'You,' your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules."

"A scientist's aim in a discussion with his colleagues is not to convince by rhetorical tricks, but to clarify the issue by steps logical and, above all, honest."

"The essence of science is to be interested in how things work and to ask logical questions about them."

"Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself."

"Time waits for no one."

"Time spent with loved ones is never wasted."

"I've been alive for a long time. Long enough to know that you can't trust anyone."

"The past always catches up with you."
