“There is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap.”

Eternity is a long time, especially towards the end.

Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.

I’m really easy to get along with once you see it my way.

We live in the most probable of all possible worlds.

We are in danger of destroying ourselves by our greed and stupidity. We cannot remain looking inwards at ourselves on a small and increasingly polluted and overcrowded planet.

Science is beautiful when it makes simple explanations of phenomena or connections between different observations.

The meaning in life is not out there but in between our ears. In many ways this makes us the lords of creation.

One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don’t throw it away.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

There is no unique picture of reality.

People who boast about their I.Q. are losers.

The thing about smart people is that they seem like crazy people to dumb people.

Keeping an active mind has been vital to my survival, as has been maintaining a sense of humor.

We don’t let animals suffer, so why humans?

The more you learn, the more you know. The more you know, the more you forget. The more you forget, the less you know. So why bother to learn.

Men are strong so long as they represent a strong idea,they become powerless when they oppose it.

No, I’m just a man committed to great ideas.

Having knowledge but lacking the power to express it clearly is no better than never having any ideas at all.

Everything changes with time. You can’t predict where you’re gonna be next year; you have no idea.

The idea of only someone else loving you is absurd. You need to learn to love yourself too.

Once you do away with the idea of people as fixed, static entities, then you see that people can change, and there is hope.

Choosing the right word, and the right word order, he illustrated, could make an enormous difference in conveying an image or an idea.

Be not astonished at new ideas; for it is well known to you that a thing does not therefore cease to be true because it is not accepted by many.
