Faith is to believe what you do not see; the reward of this faith is to see what you believe.

Bid me discourse, I will enchant thine ear.

Nothing is so easy to fake as the inner vision.

Nothing is so easy as to deceive one’s self; for what we wish, that we readily believe.

Everything that deceives does so by casting a spell.

Men willingly believe what they wish.

To ensure the adoration of a theorem for any length of time, faith is not enough; a police force is needed as well.

Appearances often are deceiving.

In the past, men created witches; now they create mental patients.

One thing alone not even God can do: to make undone whatever has been done.

The fact is certain because it is impossible.

Any serious attempt to do anything worthwhile is ritualistic.

To blow and to swallow at the same time is not easy; I cannot at the same time be here and also there.
