Many natural patterns, such as the arrangement of buds on a stem, accord with the series of Fibonacci numbers, and Fibonacci spirals are also observe… - Mary Midgley

The trouble with words like "fit" in these discussions is that, if taken in a wide sense they are liable to become vacuous, and if taken more narrowly they easily become tendentious. Thus the phrase "survival of the fittest" does not mean much if it means only "survival of those most likely to survive." If on the hand it means "survival of those whom we should admire most" or the like, it describes a different state of affairs; we shall need different arguments to persuade us that this is happening. In just the same way, Wilson equivocates with the notion that to be "fit" is an advantage to anybody. If it means "healthy" or "able to do what he wants to do" then it usually is so. But if it only means "likely to have many descendants," then there is no reason for treating it as an advantage at all.

But my present point is a much wider one. What we need, in order to feel at home in the world, is certainly not a belief that it was made for us. We are at home in this world because we were made for it. we have develped here, on this planet, and are adapted to live here. Our emotional constitution is part of that adaptation. We are not fit to live anywhere else (the possibility, such as it is, of surviving briefly, and at ruinous expense in space-craft and the like is just parasitical; it depends on extending the conditions we are used to into a few bizairre corners, not on our being able to live in other conditions.

The contrary, literalist campaign within Christianity is actually quite recent. It developed among more or less extreme Protestants after the Reformation – largely indeed in the last century in the US. It was consciously designed as a competitor with science, providing equal certainty by comparable methods. It is thus a political phenomenon, acting in some ways like a cargo cult. It has enabled relatively poor and powerless people to use their Bibles (which the Protestant Reformers had provided) to shape a rival myth of their own. They see this as an alternative to the materialist glorification of science and technology which they have perceived – with some reason – as the oppressive creed of those in power.
