Of a man's good qualities two are eminent - intelligence and speech. By the first he profits himself, and by the second he makes others profit.

The intelligent man is whoever knows how to be happier today than yesterday.

A wise man first thinks and then speaks and a fool speaks and then thinks.

God hath given His creatures nothing to place higher than reason.

A wise man needs each day an hour set apart in which to examine his conscience, and measure what he has gained or lost.

The best teaching is that which corrects you.

That knowledge is very superficial which remains only on your tongue; the intrinsic merit and value of knowledge is that you act upto it.

One questioned about a matter of which he knows not, should not blush to say: 'I do not know.'

If you hide what you know, you will be supposed to know nothing.

Do not hate what you do not know; for the greater part of knowledge consists of what you do not know.
