Things are the way they are because they were the way they were.

Words are like harpoons. Once they go in, they are very hard to pull out.

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.

It is ironic that the scientific facts throw Darwin out, but leave William Paley, a figure of fun to the scientific world for more than a century, still in the tournament with a chance of being the ultimate winner... Indeed, such a theory is so obvious that one wonders why it is not widely accepted as being self-evident. The reasons are psychological rather than scientific.

It seems to be a characteristic of all great work that it creators wear a cloak of imprecision.

One [idea] was that the Universe started its life a finite time ago in a single huge explosion, and that the present expansion is a relic of the violence of this explosion. This big bang idea seemed to me to be unsatisfactory even before detailed examination showed that it leads to serious difficulties.

When I was young, the old regarded me as an outrageous young fellow, and now that I'm old the young regard me as an outrageous old fellow.
