The more we know about this universe, the more mysterious it is. The old world that Job knew was marvelous enough, and his description of its wonders is among the noblest poetry of the race, but today the new science has opened to our eyes vistas of mystery that transcend in their inexplicable marvel anything the ancients ever dreamed.

Some things mankind can finish and be done with, but not ... science, that persists, and changes from ancient Chaldeans studying the stars to a new telescope with a 200-inch reflector and beyond; not religion, that persists, and changes from old credulities and world views to new thoughts of God and larger apprehensions of his meaning.

Liberty is always dangerous, but it is the safest thing we have.

It is not marriage that fails; it is people that fail. All that marriage does is to show people up.

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.

Don't simply retire from something; have something to retire to.

God has put within our lives meanings and possibilities that quite outrun the limits of mortality.
