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. As much as I ever did, more than I ever did, I believe in Liberalism. But there was a rosy time of innocence when I believed in Liberals.
By Liberalism Chesterton means the doctrine of self-governance.
Armageddon, indeed.
Why is it that I can’t stand bureaucracies?
