Who said “Hunger, love, pain, fear are some of those inner forces which rule the individual's…”?

“Nature is indifferent to the survival of the human species, including Americans.”

“The notion that one will not survive a particular catastrophe is, in general terms, a comfort since it is equivalent to abolishing the catastrophe.”

“Survival, with honor, that outmoded and all-important word, is as difficult as ever and as all-important to a writer. Those who do not last are always more beloved since no one has to see them in their long, dull, unrelenting, no-quarter-given-and-no-quarter-received, fights that they make to do something as they believe it should be done before they die. Those who die or quit early and easy and with every good reason are preferred because they are understandable and human. Failure and well-disguised cowardice are more human and more beloved.”

“If you live among wolves you have to act like a wolf.”

“All I'm trying to do is not join my ancestral spirits just yet.”

“The man of science is a poor philosopher.”

“Never do anything against conscience even if the state demands it.”

“We all try to escape pain and death, while we seek what is pleasant.”

“Science without religion is lame, religion without science is blind.”

“The whole of science is nothing more than a refinement of every day [sic] thinking.”

“I live in that solitude which is painful in youth, but delicious in the years of maturity.”
