Give a critic an inch, he’ll write a play. - John Steinbeck

We sat on a crate of oranges and thought what good men most biologists are, the tenors of the scientific world — temperamental, moody, lecherous, loud-laughing, and healthy.[…] Your true biologist will sing you a song as loud and off-key as will a blacksmith, for he knows that morals are too often diagnostic of prostatitis and stomach ulcers. Sometimes he may proliferate a little too much in all directions, but he is as easy to kill as any other organism, and meanwhile he is very good company, and at least he does not confuse a low hormone productivity with moral ethics.

The ways of sin are curious . . . I guess if a man had to shuck off everything he had, inside and out, he'd manage to hide a few little sins somewhere for his own discomfort. They're the last things we'll give up.

This you may say of man - when theories change and crash, when schools, philosophies, when narrow dark alleys of thought, national, religious, economic, grow and disintegrate, man reaches, stumbles forward, painfully, mistakenly sometimes. Having stepped forward, he may slip back, but only half a step, never the full step back.
