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.

Christians are supposed not merely to endure change, nor even to profit by it, but to cause it.

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

He who cannot rest, cannot work; he who cannot let go, cannot hold on; he who cannot find footing, cannot go forward.

The finest quality of our characters do not come from trying but from the mysterious and yet most effective capacity to be inspired.

No man need stay the way he is.

What a testing of character adversity is.
