People who believe the earth was created 6000 years ago, when it's actually 4.5 billion years old, should also believe the width of North America is 8 yards. That is the scale of the error.

Scientific and technological progress themselves are value-neutral. They are just very good at doing what they do. If you want to do selfish, greedy, intolerant and violent things, scientific technology will provide you with by far the most efficient way of doing so. But if you want to do good, to solve the world's problems, to progress in the best value-laden sense, once again, there is no better means to those ends than the scientific way.

Writing a computer virus program is child's play. Any fool can do it, which is why the silly little twerps who do have nothing to be proud of.

Evolution is a very, very important idea. It is the explanation for all of life - a stunningly simple, yet powerful explanation. If you think about it, before Darwin, we hadn't the foggiest idea of how we came into being. Now we do. It's still such an exciting idea that it is well worth everybody understanding it.

Part of the appeal was that Medawar was not only a Nobel Laureate, but he seemed like a Nobel Laureate; he was everything one thought a Nobel Laureate ought to be. If you have ever wondered why scientists like Popper, try Medawar's exposition. Actually most Popperian scientists have probably never tried reading anything but Medawar's exposition.

The other way is the multiverse way. That says that maybe the universe we are in is one of a very large number of universes. The vast majority will not contain life because they have the wrong gravitational constant or the wrong this constant or that constant. But as the number of universes climbs, the odds mount that a tiny minority of universes will have the right fine-tuning.

What is interesting about the scientific world view is that it is true, inspiring, remarkable and that it unites a whole lot of phenomena under a single heading.
