When a politician uses the word 'folks,' we should brace ourselves for the deceit, or worse, that is coming.

If a child from an Amazonian hunter-gatherer tribe comes to Boston, is raised in Boston, that child will be indistinguishable in language capacities from my children growing up here, and vice versa.

Growing up in the place I did I never was aware of any other option but to question everything.

I don't join the New Atheists. So, for example, I wouldn't have the arrogance to lecture some mother who hopes to see her dying child in Heaven - that's none of my business, ultimately. I won't lecture her on the philosophy of science.

Let us not deceive ourselves; we must elect world peace or world destruction.

I can have peace of mind only when I forgive rather than judge.

It's just too late to ban all guns. There are 300 million. We should've done that after the Civil War - that's when we should've taken away guns and defined what militias were. But we didn't do it then, and we can't now.

The fact that you had disruptions in the peace process was not only in Rwanda. We had the same problem in Cambodia, we had the same problem in Mozambique, we had the same problem in Salvador.
