Perpetual adolescence

From Chesterton:

They are not crying for the moon, which is a definite and therefore a defensible desire. They are crying for the world; and when they had it, they would want another one. In the last resort they would like to try every situation, not in fancy but in fact, but they cannot refuse any and therefore cannot resolve on any. In so far as this is the modern mood, it is a thing so deadly as to be already dead. What is vitally needed everywhere, in art as much as in ethics, in poetry as much as in politics, is choice; a creative power in the will as well as in the mind. Without that self-limitation of somebody, nothing living will ever see the light.
