Preaching is personal counseling on a group basis.

No character is ultimately tested until it has suffered.

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.
