Science can only ascertain what is, but not what should be, and outside of its domain value judgements of all kinds remain necessary.
Faith and Reason are like two wings of the human spirit by which is soars to the truth.
Life is a battle between faith and reason in which each feeds upon the other, drawing sustenance from it and destroying it.
It is wrong always, everywhere, and for everyone, to believe anything upon insufficient evidence.
Faith means belief in something concerning which doubt is theoretically possible.
Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. With such persons, gullibility, which they call faith, takes the helm from the hand of reason, and the mind becomes a wreck.
Most men seem to live according to sense rather than reason.
For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.
Faith is not belief without proof, but trust without reservation.
For what is faith unless it is to believe what you do not see?
