A learned fool is more a fool than an ignorant fool.

It is the peculiar quality of a fool to perceive the faults of others and to forget his own.

He that knows himself, knows others; and he that is ignorant of himself, could not write a very profound lecture on other men's heads.

An ignorant person is one who doesn't know what you have just found out.

He that is taught only by himself has a fool for a master.

Whenever you argue with another wiser than yourself in order that others may admire your wisdom, they will discover your ignorance.

In the clashes between ignorance and intelligence, ignorance is generally the aggressor.

Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune.

It is in his knowledge that man has found his greatness and his happiness, the high superiority which he holds over the other animals who inhabit the earth with him, and consequently no ignorance is probably without loss to him, no error without evil.

An ignorance of means may minister to greatness, but an ignorance of aims make it impossible to be great at all.
