G. K. Chesterton on Idealism

“The great ideals of the past failed not by being outlived (which must mean over-lived), but by not being lived enough. Mankind has not passed through the Middle Ages. Rather mankind has retreated from the Middle Ages in reaction and rout. The Christian ideal has not been tried and found wanting. It has been found difficult; and left untried.”

“The highest point of democratic idealism and conviction was towards the end of the eighteenth century, when the American Republic was "dedicated to the proposition that all men are equal." It was then that the largest number of men had the most serious sort of conviction that the political problem could be solved by the vote of peoples instead of the arbitrary power of princes and privileged orders.'''”

“It is a common error, I think, among the Radical idealists of my own party and period to suggest that financiers and business men are a danger to the empire because they are so sordid or so materialistic. The truth is that financiers and business men are a danger to the empire because they can be sentimental about any sentiment, and idealistic about any ideal, any ideal that they find lying about, just as a boy who has not known much of women is apt too easily to take a woman for the woman, so these practical men, unaccustomed to causes, are always inclined to think that if a thing is proved to be an ideal it is proved to be the ideal. … Human nature simply cannot subsist without a hope and aim of some kind; as the sanity of the Old Testament truly said, where there is no vision the people perisheth. But it is precisely because an ideal is necessary to man that the man without ideals is in permanent danger of fanaticism.”
