Darwin matters because evolution matters. Evolution matters because science matters. Science matters because it is the preeminent story of our age, an epic saga about who we are, where we came from and where we are going.

In the past 10,000 years, humans have devised roughly 100,000 religions based on roughly 2,500 gods. So the only difference between myself and the believers is that I am skeptical of 2,500 gods whereas they are skeptical of 2,499 gods. We're only one God away from total agreement.

The recent medical controversy over whether vaccinations cause autism reveals a habit of human cognition — thinking anecdotally comes naturally, whereas thinking scientifically does not.

Science is not a thing. It's a verb. It's a way of thinking about things. It's a way of looking for natural explanations for all phenomena.

I’m a skeptic not because I do not want to believe, but because I want to know. How can we tell the difference between what we would like to be true and what is actually true? The answer is science.

If spirituality is the sense of awe and humility in the face of the creation, what could be more awesome and humbling than the deep space discovered by Hubble and the cosmologists, and the deep time discovered by Darwin and the evolutionists.

I care what is actually true, even more than what I hope is true.
