“We know accurately only when we know little; doubt grows with knowledge.”

Knowing is not enough; we must apply. Willing is not enough; we must do.

One ought, every day at least, to hear a little song, read a good poem, see a fine picture, and, if it were possible, to speak a few reasonable words.

There is no past we can bring back by longing for it. There is only an eternal now that builds and creates out of the past something new and better.

The intelligent man finds everything laughable, the sensible man hardly anything.

The suffering may be moral or physical; and in my opinion it is just as absurd to call a man a coward who destroys himself, as to call a man a coward who dies of a malignant fever.

Doubt can only be removed by action.

There is nothing worse than aggressive stupidity.

Daring ideas are like chessmen moved forward. They may be beaten, but they may start a winning game.

Love is an ideal thing, marriage a real thing.

The human race is a monotonous affair. Most people spend the greatest part of their time working in order to live, and what little freedom remains so fills them with fear that they seek out any and every means to be rid of it.

Love does not dominate; it cultivates.

Everybody wants to be somebody, but nobody wants to grow.

For a man to achieve all that is demanded of him, he must regard himself as greater than he is.

He is happiest, be he king or peasant, who finds peace in his home.

To be loved for what one is, that is the greatest exception. The great majority love in others only what they lend him; their own selves, their version of him.

{While meditating} I sit quietly and rest in the nature of mind; I don’t question or doubt whether I am in the “correct” state or not.

I’ve got to start listening to those quiet, nagging doubts.

I studied that first Karpov-Kasparov match for a year and a half before I cracked it, what they were doing, and discovered that it was all prearranged move-by-move. There’s no doubt of it in my mind.

John Kricfalusi is very talented; he used to really piss me off. But I did good work, you know? The Ren & Stimpy show without me was totally unsuccessful.

Faith keeps you going, but doubt keeps you from going off the deep end.

Courage doesn’t mean we’re not afraid anymore, it just means our actions aren’t controlled by our doubts.

People in so many countries look up to the United States as a model of democracy, but I doubt if that can continue. It leaves me with a great sense of loss.

Every artist learns through imitation, but I rather doubt the aim of these things is artistic development.
