“Question everything. Learn something. Answer nothing.”

You will not achieve happiness if you don’t work hard; and it’s a shame not to want to work hard.

My love for you was greater than my wisdom.

When love is in excess, it brings a man no honor, no worthiness.

The stillest tongue can be the truest friend.

Man’s best possession is a sympathetic wife.

Love is all we have, the only way that each can help the other.

There is in the worst of fortune the best of chances for a happy change.

Do not mistake the rule of force for true power. Men are not shaped by force.

It is the wise man’s part to leave in darkness everything that is ugly.

Stronger than lover’s love is lover’s hate. Incurable, in each, the wounds they make.

Action achieves more than words.

Man’s most valuable trait is a judicious sense of what not to believe.

The man is happiest who lives from day to day and asks no more, garnering the simple goodness of life.

Death is the only water to wash away this dirt.

The same man cannot well be skilled in everything; each has his special excellence.

No one who lives in error is free.

I began my education at a very early age; in fact, right after I left college.

The more knowledge you have, the more you’re free to rely on your instincts.

To attain knowledge, add things everyday. To attain wisdom, remove things every day.

Information is not knowledge.

The real art is knowing what to leave out, not what to put in.

Once you stop learning, you start dying.

It strikes me that all our knowledge about the structure of our Earth is very much like what an old hen would know of the hundred-acre field in a corner of which she is scratching.

Share your knowledge. It is a way to achieve immortality.
