Curiosity is a willing, a proud, an eager confession of ignorance. – S. Leonard Rubinstein, Writing: A Habit of Mind

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

Curiosity is only vanity. Most frequently we wish not to know, but to talk. We would not take a sea voyage for the sole pleasure of seeing without hope of ever telling. – Blaise Pascal, Pensées
