You ask me for a motto. Here it is: SERVICE.

Every start on an untrodden path is a venture which only in unusual circumstances looks sensible and likely to succeed.

Not less strong than the will to truth must be the will to sincerity. Only an age, which can show the courage of sincerity, can possess truth, which works as a spiritual force within it.

In case my life should end with the cannibals, I hope they will write on my tombstone, 'We have eaten Dr. Schweitzer. He was good to the end.'

Let me give you a definition of ethics: It is good to maintain and further life it is bad to damage and destroy life.

Cold completely introspective logic places a philosopher on the road to the abstract. Out of this empty, artificial act of thinking there can result, of course, nothing which bears on the relation of man to himself, and to the universe.

Ethics is nothing else than reverence for life.
