“Man's wonder grows with his knowledge.”

“As a man's knowledge grows, and his power increases, the road he takes grows ever narrower, until at last he does only and wholly what he must.”

“As a man's real power grows and his knowledge widens, ever the way he can follow grows narrower: until at last he chooses nothing,but does only and wholly what he must do...”

“[T]he essence of belief is doubt, the essence of reality is questioning. The essence of Time is Flow, not Fix. The essence of faith is the knowledge that all flows and that everything must change. The growing man is Man Alive, and his "philosophy" must grow, must flow, with him. . . . the man too fixed today, unfixed tomorrow - and his body of beliefs is nothing but a series of fixations.”

“A person of little knowledge Grows old as a plough-ox grows old.His fleshes increases; His wisdom does not increase.”

“Doubt grows with knowledge.”
