It may be important to great thinkers to examine the world, to explain and despise it. But I think it is only important to love the world, not to despise it, not for us to hate each other, but to be able to regard the world and ourselves and all beings with love, admiration and respect.
The books that help you most are those which make you think that most. The hardest way of learning is that of easy reading; but a great book that comes from a great thinker is a ship of thought, deep freighted with truth and beauty.
Readers are plentiful; thinkers are rare.
The greatest challenge to any thinker is stating the problem in a way that will allow a solution.
I'm not afraid of facts, I welcome facts but a congeries of facts is not equivalent to an idea. This is the essential fallacy of the so-called "scientific" mind. People who mistake facts for ideas are incomplete thinkers; they are gossips.

A thinker sees his own actions as experiments and questions--as attempts to find out something. Success and failure are for him answers above all.
