Every man ought to be inquisitive through every hour of his great adventure down to the day when he shall no longer cast a shadow in the sun. For if he dies without a question in his heart, what excuse is there for his continuance.
~ Frank Moore Colby

A faith without curiosity is like a seed that does not grow. Indifference is farther from faith than doubt or rebellion.
~ Peter Kreeft

Only the curious will learn and only the resolute overcome the obstacles to learning. The quest quotient has always excited me more than the intelligence quotient.
~ Eugene S. Wilson
