Mind

I always voted at my party's call, and I never thought of thinking for myself at all.

You have not converted a man because you have silenced him

A healthful hunger for a great idea is the beauty and blessedness of life

You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.

I take a simple view of life. It is keep your eyes open and get on with it.

Every creature is better alive than dead, men and moose and pine trees, and he who understands it aright will rather preserve its life than destroy it.

Old minds are like old horses; you must exercise them if you wish to keep them in working order

I've always felt that a person's intelligence is directly reflected by the number of conflicting points of view he can entertain simultaneously on the same topic.

Talking with a friend is nothing else but thinking aloud

Reading is to the mind what exercise is to the body

Nothing is more gratifying to the mind of man than power or dominion

Our disputants put me in mind of the scuttle fish, that when he is unable to extricate himself, blackens all the water about him, till he becomes invisible

The hours of a wise man are lengthened by his ideas

A contented mind is the greatest blessing a man can enjoy in this world

Cheerfulness keeps up a kind of daylight in the mind, filling it with a steady and perpetual serenity

Thought means life, since those who do not think so do not live in any high or real sense. Thinking makes the man

Who knows, the mind has the key to all things besides

One must be a wise reader to quote wisely and well

The investigation of the meaning of words is the beginning of education

Not to unlearn what you have learned is the most necessary kind of learning.
