Three elements go to make up an idea. The first is its intrinsic quality as a feeling. The second is the energy with which it affects other ideas, an energy which is infinite in the here-and-nowness of immediate sensation, finite and relative in the recency of the past. The third element is the tendency of an idea to bring along other ideas with it.
Ideas never lack for words. It is words that lack ideas. As soon as the idea has come to its last degree of perfection, the word blossoms; or, if you like, it blossoms from the word that presents it and clothes it.
Between ourselves and our real natures we interpose that wax figure of idealizations and selections which we call our character. We extend this into all our thinking. Between us and the realities of social life we build up a mass of generalizations, abstract ideas, ancient glories, and personal wishes. They simplify and soften experience. It is so much easier to talk of poverty than to think of the poor, to argue the rights of capital than to see its results. Pretty soon we come to think of the theories and abstract ideas as things in themselves. We worry about their fate and forget their original content.
It is terrible to see how a single unclear idea, a single formula without meaning, lurking in a young man's head, will sometimes act like an obstruction of inert matter in an artery, hindering the nutrition of the brain and condemning its victim to pine away in the fullness of his intellectual vigor and in the midst of intellectual plenty.
