What's Wrong with the World by G.K. Chesterton

There is a popular philosophical joke intended to typify the endless and useless arguments of philosophers; I mean the joke about which came first, the chicken or the egg? I am not sure that properly understood, it is so futile an inquiry after all. I am not concerned here to enter on those deep metaphysical and theological differences of which the chicken and egg debate is a frivolous, but a very felicitous, type. The evolutionary materialists are appropriately enough represented in the vision of all things coming from an egg, a dim and monstrous oval germ that had laid itself by accident. That other supernatural school of thought (to which I personally adhere) would be not unworthily typified in the fancy that this round world of ours is but an egg brooded upon by a sacred unbegotten bird; the mystic dove of the prophets. But it is to much humbler functions that I here call the awful power of such a distinction.

Whether or no the living bird is at the beginning of our mental chain, it is absolutely necessary that it should be at the end of our mental chain. The bird is the thing to be aimed at -- not with a gun, but a life-bestowing wand. What is essential to our right thinking is this: that the egg and the bird must not be thought of as equal cosmic occurrences recurring alternatively forever. They must not become a mere egg and bird pattern, like the egg and dart pattern. One is a means and the other an end; they are in different mental worlds. Leaving the complications of the human breakfast-table out of account, in an elemental sense, the egg only exists to produce the chicken. But the chicken does not exist only in order to produce another egg. He may also exist to amuse himself, to praise God, and even to suggest ideas to a French dramatist. Being a conscious life, he is, or may be, valuable in himself.
