From Anthony de Mello, SJ (1931–87), One Minute Wisdom (New York: Doubleday, 1986), p. 70:

To a visitor who described himself as a seeker after Truth the Master said, “If what you seek is Truth, there is one thing you must have above all else.”

“I know. An overwhelming passion for it.”

“No. An unremitting readiness to admit you may be wrong.”
