The Only Real Valuable Thing Is Intuition

"The only true wisdom is in knowing you know nothing."

"The only source of knowledge is experience."

"The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it Intuition or what you will, the solution comes to you and you don't know how or why."

"Any fool can know. The point is to understand."

"Learning is experience. Everything else is just information."

"Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life."
