“The recipe for perpetual ignorance is: Be satisfied with your opinions and content with your knowledge.”

“To be truly ignorant, be content with your own knowledge.”

“You are not entitled to your opinion. You are entitled to your informed opinion. No one is entitled to be ignorant.”

“There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance.”

“The first step towards knowledge is to accept your own ignorance.”

“O perpetual revolution of configured stars, o perpetual recurrence of determined seasons, o world of spring and autumn, birth and dying! The endless cycle of idea and action, endless invention, endless experiment, brings knowledge of motion, but not of stillness; knowledge of speech, but not of silence; knowledge of words, and ignorance of the Word. All our knowledge brings us nearer to our ignorance, all our ignorance brings us nearer to death, but nearness to death no nearer to God. Where is the Life we have lost in living? Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information? The cycles of Heaven in twenty centuries bring us farther from God and nearer to the Dust.”
