"Skepticism is the chastity of the intellect, and it is shameful to surrender it too soon or to the first comer: there is nobility in preserving it coolly and proudly through long youth, until at last, in the ripeness of instinct and discretion, it can be safely exchanged for fidelity and happiness."

--George Santayana, Quoted by Carl Sagan in Contact, Chapter 14 "Harmonic Oscillator", page 231
