Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

The likelihood of the formation of life from inanimate matter is 1 to a number with 40,000 noughts after it (1040,000).... It is big enough to bury Darwin and the whole theory of evolution. There was no primeval soup, neither on this planet nor any other, and if the beginnings of life were not random, they must therefore have been the product of purposeful intelligence.

With savages, the weak in body or mind are soon eliminated. We civilized men, on the other hand, do our utmost to check the process of elimination. We build asylums for the imbecile, the maimed and the sick. Thus the weak members of civilized societies propagate their kind. No one who has attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man. Hardly anyone is so ignorant as to allow his worst animals to breed.

I myself am convinced that the theory of evolution, especially to the extent to which it has been applied, will be one of the greatest jokes in the history books of the future. Posterity will marvel that so very flimsy and dubious an hypothesis could be accepted with the incredible credulity it has.

Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.

Modern literary theory sees a similarity between walking and writing that I find persuasive: words inscribe a text in the same way that a walk inscribes space. In The practicse of Everyday Life, Michel de Certeau writes, 'The act of walking is a process of appropriation of the topographical system on the part of the pedestrian; it is a special acting-out of the place...and it implies relations among differentiated positions.' I think this is a fancy way of saying that writing is one way of making the world our own, and that walking is another.

Darwin's theory of evolution is the last of the great nineteenth-century mystery religions.
