Nature does nothing in vain.

Those who hope for no other life are dead even for this.

The assumption is that your personal life has to be a mess to create, but how much chaos can you allow in before it takes over?

Thus so wretched is man that he would weary even without any cause for weariness… and so frivolous is he that, though full of a thousand reasons for weariness, the least thing, such as playing billiards or hitting a ball, is sufficient enough to amuse him.

Not only must we be good, but we must also be good for something.

I love the attention but I don’t like too much of it.

I tell you, we are here on Earth to fart around, and don’t let anybody tell you different.

The world is like a grand staircase, some are going up and some are going down.

Man wants to live, but it is useless to hope that this desire will dictate all his actions.

The cause of my life has been to oppose superstition. It’s a battle you can’t hope to win – it’s a battle that’s going to go on forever. It’s part of the human condition.

Since God created the world, He also created reality.

Men create gods after their own image, not only with regard to their form but with regard to their mode of life.

There are truths which are not for all men, nor for all times.

Too much and too little wine. Give him none, he cannot find truth; give him too much, the same.

If pleasure was not followed by pain, who would forbear it?

One of the best ways to see tree flowers is to climb one of the tallest trees and to get into close, tingling touch with them, and then look broad.

Knowledge is true opinion.

How inappropriate to call this planet Earth when it is quite clearly Ocean.

Modern science says: ‚The sun is the past, the earth is the present, the moon is the future.‘ From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

Nothing cannot exist forever.

In nature, nothing is perfect and everything is perfect. Trees can be contorted, bent in weird ways, and they’re still beautiful.

Mankind is not likely to salvage civilization unless he can evolve a system of good and evil which is independent of heaven and hell.

It’s not called quitting if you quit while you ahead. It’s about being aware and being strategic enough to know that you got to get out the pool at some point. You got to put your clothes back on and dry off.

See that the imagination of nature is far, far greater than the imagination of man.

It is a mania shared by philosophers of all ages to deny what exists and to explain what does not exist.

Pointing is a metaphor we all know. We’ve done a lot of studies and tests on that, and it’s much faster to do all kinds of functions, such as cutting and pasting, with a mouse, so it’s not only easier to use but more efficient.

Nothing in the affairs of men is worthy of great anxiety.

Technological progress has merely provided us with more efficient means for going backwards.

If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.
