“One thing in life is for certain, the more profoundly baffled you have been in your life, the more open your mind becomes to new ideas.”

No one is dumb who is curious. The people who don’t ask questions remain clueless throughout their lives.

Aliens might be surprised to learn that in a cosmos with limitless starlight, humans kill for energy sources buried in the sand.

I know of no time in human history where ignorance was better than knowledge.

As they are currently practiced, there is no common ground between science and religion… Although just as in hostage negotiations, it’s probably best to keep both sides talking to each other.

Our nation is turning into an idiocracy.

If your belief system is not founded in an objective reality, you should not be making decisions that affect other people.

Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.

I dream of a world where the truth is what shapes people’s politics, rather than politics shaping what people think is true.

If you need to invoke your academic pedigree or job title for people to believe what you say, then you need a better argument.

The day that you stop looking – because you’re content God did it – I don’t need you in the lab. You’re useless on the frontier of understanding the nature of the world.

As areas of knowledge grow, so too do the perimeters of ignorance.

Pretending to know everything closes the door to finding out what’s really there.

Somehow it’s O.K. for people to chuckle about not being good at math. Yet if I said, ‘I never learned to read,’ they’d say I was an illiterate dolt.

Curiously, light-loving green plants reject the Sun’s green light, reflecting it back at you, which is why they look green.

Claiming there is no other life in the universe is like scooping up some water, looking at the cup and claiming there are no whales in the ocean.

We live in a world where not everyone has the urge to help others. It is OK to encourage others to pull themselves up by the bootstraps, but if you do, just remember that some people have no boots.

The good ideas will survive.

As we willingly enter each place of fear, each place of deficiency and insecurity in ourselves, we will discover that its walls are made of untruths, of old images of ourselves, of ancient fears, of false ideas of what is pure and what is not.

I intend to leave after my death a large fund for the promotion of the peace idea, but I am skeptical as to its results.

One can steal ideas, but no one can steal execution or passion.

We do not support the man. We do not support the individual. We support the idea of independent revolution in the Western Hemisphere, free from American intervention.

By what strange law of mind is it that an idea long overlooked, and trodden under foot as a useless stone, suddenly sparkles out in new light, as a discovered diamond?

The moment you declare a set of ideas to be immune from criticism, satire, derision, or contempt, freedom of thought becomes impossible.

A distinction must be made between true and false ideas, and that too much rein must not be given to a man’s imagination under pretext of its being a clear and distinct intellection.
