I grow daily to honor facts more and more, and theory less and less. A fact, it seems to me, is a great thing -- a sentence printed, if not by God, then at least by the Devil.

Men on their side must force themselves for a while to lay their notions by and begin to familiarize themselves with facts.

General principles are not the less true or important because from their nature they elude immediate observation; they are like the air, which is not the less necessary because we neither see nor feel it.

Facts don't cease to exist because they are ignored.

Facts and truth really don't have much to do with each other.

Blessed is the man who, having nothing to say, abstains from giving us wordy evidence of the fact.

Those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.

Facts are counterrevolutionary.

If the facts don't fit the theory, change the facts.

The god whom science recognizes must be a God of universal laws exclusively, a God who does a wholesale, not a retail business. He cannot accommodate his processes to the convenience of individuals.
