An asteroid could hit us at any moment. This is not - and also, the most successful kind of life on this planet is not us, it's microbes. They're the ones who greatly outnumber us, and may eventually destroy us.

There is the fear, common to all English-only speakers, that the chief purpose of foreign languages is to make fun of us. Otherwise, you know, why not just come out and say it?

our great common challenge ... is to free people from religion, get it out of our laws, our schools, our health systems, our government and, I would add, also our sporting events. I would really like to see some separation of church and stadium, if we could work on that.

We who officially value freedom of speech above life itself seem to have nothing to talk about but the weather.

Human intellectual progress, such as it has been, results from our long struggle to see things 'as they are,' or in the most universally comprehensible way, and not as projections of our own emotions. Thunder is not a tantrum in the sky, disease is not a divine punishment, and not every death or accident results from witchcraft. What we call the Enlightenment and hold on to only tenuously, by our fingernails, is the slow-dawning understanding that the world is unfolding according to its own inner algorithms of cause and effect, probability and chance, without any regard for human feelings.

I think it's tragic that we have this human capacity, which appears to be hardwired, or so the evolutionary biologists say, for collective joy. We have these techniques for generating it that go back thousands of years, and yet we tend not to use this.

The one regret I have about my own abortions is that they cost money that might otherwise have been spent on something more pleasurable, like taking the kids to movies and theme parks.
