You believe easily that which you hope for earnestly.

The great masses of the people ... will more easily fall victims to a great lie than to a small one.

There's a sucker born every minute.

The more gross the fraud, the more glibly will it go down and the more greedily will it be swallowed, since folly will always find faith wherever imposters will find impudence.

The only disadvantage of an honest heart is credulity.

Let us believe neither half of the good people tell us of ourselves, nor half the evil they say of others.
