The most imaginative people are the most credulous, for to them everything is possible.

Precisely in proportion to our own intellectual weakness will be our credulity as to those mysterious powers assumed by others.

Our credulity is greatest concerning the things we know least about. And since we know least about ourselves, we are ready to believe all that is said about us. Hence the mysterious power of both flattery and calumny.

Each believes easily what he fears and what he desires.

Credulity is the man's weakness, but the child's strength.

There is no crime in the cynical American calendar more humiliating than to be a sucker.
