MaimonidesTo sum up: I am the man who when the concern pressed him and his way was straitened and he could find no other device by which to teach a demonstrable truth other than by giving satisfaction to a single virtuous man while displeasing ten thousand ignoramuses - I am he who prefers to address that single man by himself, and I do not heed the blame of those many creatures.
MaimonidesGive a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.
