“Nothing of importance is ever achieved without discipline. I feel myself sometimes not wholly in sympathy with some modern educational theorists, because I think that they underestimate the part that discipline plays. But the discipline you have in your life should be one determined by your own desires and your own needs, not put upon you by society or authority.”

“Education is the most powerful weapon which you can use to change the world.”

“The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.”

“Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.”

“The good life is one inspired by love and guided by knowledge.”
