No man need stay the way he is.

Granted the endless variations of moral customs, still the essential standards persist. As in a scientific laboratory, all else may change but the standards are unalterable- disinterested love of truth, fidelity to facts, accuracy in measurement, exactness of verification-so, in life as a whole, the towering ethical criteria remain unshaken. Falsehood is never better than truth, theft better than than honesty, treachery better than loyalty, cowardice better than courage.

One could almost phrase the motto of our modern civilization thus: Science is my shepherd; I shall not want.

The tragic evils of our life are so commonly unintentional. We did not start out for that poor, cheap goal. That aim was not in our minds at all....Look to the road you are walking on. He who picks up one end of [a] stick picks up the other.He who chooses the beginning of a road chooses the place it leads to.

The steady discipline of intimate friendship with Jesus results in men becoming like Him.

Every great scientist becomes a great scientist because of the inner self-abnegation with which he stands before truth, saying: "Not my will, but thine, be done." What, then, does a man mean by saying, Science displaces religion, when in this deep sense science itself springs from religion?
