哲学的本质不是拥有真理，而是寻找真理。

If you are ready to give up everything else and study the whole history and background of the market and all the principal companies whose stocks are on the board as carefully as a medical student studies anatomy—if you can do all that and in addition you have the cool nerves of a gambler, the sixth sense of a clairvoyant and the courage of a lion, you have a ghost of a chance.

心灵不是感官信息的被动接受者，而是感知过程中的积极参与者。
