The conclusion of intelligent design flows naturally from the data itself - not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.

In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.

Science is not a game in which arbitrary rules are used to decide what explanations are to be permitted.

We are not inferring design to account for a black box, but to account for an open box.

The conclusion of design flows naturally from the data; we should not shrink from it; we should embrace it and build on it.

As can be seen even by this limited number of examples proteins carry out amazingly diverse functions.

It was only about sixty years ago that the expansion of the universe was first observed.
