There are only two races on this planet - the intelligent and the stupid.

The intellect of the wise is like glass it admits the light of heaven and reflects it.

There is no method but to be very intelligent.

Ah! yes I know: those who see me rarely trust my word: I must look too intelligent to keep it.

Often the hands will solve a mystery that the intellect has struggled with in vain.

We should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.

There are some ideas so wrong that only a very intelligent person could believe in them.

The voice of the intellect is a soft one but it does not rest until it has gained a hearing.

An intellectual is a man who takes more words than necessary to tell more than he knows.

Being an intellectual creates a lot of questions and no answers.
