More quotes by Oliver Wendell Holmes Sr.

"It's faith in something and enthusiasm for something that makes a life worth living."
"Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad."
"Science is the topography of ignorance."
"Science is a first-rate piece of furniture for a man's upper chamber, if he has common sense on the ground floor."
"The best of a book is not the thought which it contains, but the thought which it suggests; just as the charm of music dwells not in the tones but in the echoes of our hearts."
