There is a tendency for people to say evolution is only a theory. That is inappropriate.

We think we know that chimpanzees are higher animals and earthworms are lower, we think we've always known what that means, and we think evolution makes it even clearer. But it doesn't. It is by no means clear that it means anything at all. Or if it means anything, it means so many different things to be misleading, even pernicious.

Either it is true that a medicine works or it isn't. It cannot be false in the ordinary sense but true in some alternative sense. If a therapy or treatment is anything more than a placebo, properly conducted double-blind trials, statistically analyzed, will eventually bring it through with flying colours. Many candidates for recognition as orthodox medicines fail the test and are summarily dropped. The alternative label should not (though, alas, it does) provide immunity from the same fate.
