Science, as opposed to technology, does violence to common sense.

Steve Grand is the creator of what I think is the nearest approach to artificial life so far, and his first book, Creation: Life and How to Make It, is as interesting as you would expect. But he illuminates more than just the properties of life: his originality extends to matter itself and the very nature of reality. Not since David Deutsch's The Fabric of Reality have I encountered such a compelling invitation to think everything out afresh, from the bottom up.

Creationism: God's gift to the ignorant.

I personally would go further and say that, if your morality is based, as mine is, on a desire to increase the sum of happiness and reduce suffering, the decision to deliberately give birth to a Down baby, when you have the choice to abort it early in the pregnancy, might actually be immoral from the point of view of the child’s own welfare.

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.

If complex organisms demand an explanation, so does a complex designer. And it's no solution to raise the theologian's plea that God (or the Intelligent Designer) is simply immune to the normal demands of scientific explanation. To do so would be to shoot yourself in the foot. You cannot have it both ways. Either ID belongs in the science classroom, in which case it must submit to the discipline required of a scientific hypothesis. Or it does not, in which case, get it out of the science classroom and send it back to church, where it belongs.

Science has eradicated smallpox, can immunise against most previously deadly viruses, can kill most previously deadly bacteria. Theology has done nothing but talk of pestilence as the wages of sin.
