“When scientifically investigating the natural world, the only thing worse than a blind believer is a seeing denier.”

Knowledge of the natural world and how it works should be counted as fundamental to informed governance. You can’t have a functioning democracy, if the electorate is under-informed or, worse, mis-informed.

There’s a saying in the scientific community, that every great truth goes through three phases. First, people deny it. Second, they say that it conflicts with the Bible. Third, they say that they’ve known it all along.

To be scientifically literate is to empower yourself to know when someone else is full of bullshit.

It’s better to understand something than to memorize something.

I wonder if, in fact, we have been observed by aliens and upon close examination of human conduct and human behavior they have concluded that there is no sign of intelligent life on Earth.

I think the best thing a parent can do, when raising a child, is simply get out of their way.

Everyone should have their mind blown once a day.

After 50 years of television, there’s no other conclusion the aliens could draw, but that most humans are neurotic, death-hungry, dysfunctional idiots.

Practically every food you buy in a store for consumption by humans is genetically modified food. There are no wild, seedless watermelons. There’s no wild cows.

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.

We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.

If you’re really successful at bullshitting, it means you’re not hanging around enough people smarter than you.

Imagine a world in which we are all enlightened by objective truths rather than offended by them.

In the end, it’s the people who are curious who change the world.

To learn more about science, turn off your electronic device and go outside and look around a bit. Nature is calling you. Go on. The internet will still be here.

You don’t want to raise a kid in a culture where the kid who asks the most questions is annoying. You want a culture where the kid who asks the most questions gets awards and gets another piece of cake.

I believe we have a responsibility to do even more. It’s so important that we’re changing.

I know you won’t believe me, but the highest form of Human Excellence is to question oneself and others.

What you do is proof of what you believe.

To believe in something, and not to live it, is dishonest.

There are some ideas so absurd that only an intellectual could believe them.

Despite everything, I believe that people are really good at heart.

Commitment is a big part of what I am and what I believe.

Three rules: I do not eat too much; I do not worry too much; and, if I do my best, I believe that what happens, happens for the best.
