Belief In Nothing
It is better to be a fool who believes in everything than to be so clever that you do not believe in anything.
If you believe in everything, some of your beliefs may be foolish but you will also believe in the truth. However, when a person is too clever and does not want to believe in anything, he may begin by ridiculing falsehood and folly but can easily end up so skeptical of everything that he even denies the truth.
(Rebbe Nachman of Breslov)
