Poets utter great and wise things which they do not themselves understand.

As a young man you don't notice at all that you were, after all, badly affected. For years afterwards, at least ten years, I kept getting these dreams, in which I had to crawl through ruined houses, along passages I could hardly get through.

Otto Dix

You must learn day by day, year by year to broaden your horizon. The more things you love, the more you are interested in, the more you enjoy, the more you are indignant about, the more you have left when anything happens.

Ethel Barrymore

Cleverness is not wisdom.

Euripides

Science attempts to analyze how things and people and animals behave; it has no concern whether this behavior is good or bad, is purposeful or not. But religion is precisely the quest for such answers: whether an act is right or wrong, good or bad, and why.

Warren Weaver

The great act of faith is when a man decides he is not God.

Oliver Wendell Holmes, Jr.

The egoism which enters into our theories does not affect their sincerity; rather, the more our egoism is satisfied, the more robust is our belief.

George Eliot

Nature, like man, sometimes weeps from gladness.

Benjamin Disraeli

The limits of the possible can only be defined by going beyond them into the impossible.

Arthur C. Clarke

But honestly, if you do a rigorous survey of my work, I'll bet you'll find that biology is a theme far more often than physical science.

David Brin

Peace is its own reward.

Mahatma Gandhi

If you don't have any fight in you, you might as well be dead.

Scott Caan

Money is in some respects life's fire: it is a very excellent servant, but a terrible master.

P. T. Barnum
