Give me a smart idiot over a stupid genius any day.

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

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

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

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