Charles Darwin

“If I had my life to live over again, I would have made a rule to read some poetry and listen to some music at least once every week.”

“A man who dares to waste one hour of time has not discovered the value of life.”

“What a book a devil's chaplain might write on the clumsy, wasteful, blundering, low, and horribly cruel work of nature!”

“I am turned into a sort of machine for observing facts and grinding out conclusions.”

“A man who dares to waste one hour of time has not discovered the value of life.”

“My mind seems to have become a kind of machine for grinding general laws out of large collections of facts.”
