Here's G. K. Chesterton, writing just over a hundred years ago, in the excellent (and still timely) book, What's Wrong With the World:
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. Now our modern politics are full of a noisy forgetfulness; forgetfulness that the production of this happy and conscious life is after all the aim of all complexities and compromises. We talk of nothing but useful men and working institutions; that is, we only think of the chickens as things that will lay more eggs. Instead of seeking to breed our ideal bird, the eagle of Zeus or the Swan of Avon, or whatever we happen to want, we talk entirely in terms of the process and the embryo. The process itself, divorced from its divine object, becomes doubtful and even morbid; poison enters the embryo of everything; and our politics are rotten eggs.
And, for good measure, this from Orthodoxy:
When the business man rebukes the idealism of his office-boy, it is commonly in some such speech as this: "Ah, yes, when one is young, one has these ideals in the abstract and these castles in the air; but in middle age they all break up like clouds, and one comes down to a belief in practical politics, to using the machinery one has and getting on with the world as it is." Thus, at least, venerable and philanthropic old men now in their honoured graves used to talk to me when I was a boy. But since then I have grown up and have discovered that these philanthropic old men were telling lies. What has really happened is exactly the opposite of what they said would happen. They said that I should lose my ideals and begin to believe in the methods of practical politicians. Now, I have not lost my ideals in the least; my faith in fundamentals is exactly what it always was. What I have lost is my old childlike faith in practical politics. I am still as much concerned as ever about the Battle of Armageddon; but I am not so much concerned about the General Election. As a babe I leapt up on my mother's knee at the mere mention of it. No; the vision is always solid and reliable. The vision is always a fact. It is the reality that is often a fraud.
Some may call is cynicism, I suppose. But, considering how little things really change, I think of it as realism.
