We tend to judge others by ourselves, and because scientific and philosophic books are composed by men in whom the reasonable, logical and objective habit of mind predominates, a similar rationality has been attributed by them to the average and ordinary man. It is then overlooked that both rationality and irrationality are largely irrelevant and episodical in undisciplined human nature; that men are governed by memory rather than by thought, and that memory is not a remembering of actual facts, but is association, suggestion, dramatic fancy. The standard used to measure the value of the suggestions that spring up in the mind is not congruity with fact but emotional congeniality. Do they stimulate and reinforce feeling, and fit into the dramatic tale? Are they consonant with the prevailing mood, and can they be rendered into the traditional hopes and fears of the community:? If we are willing to take the word dreams with a certain liberality, it is hardly too much to say that man, save in his occasional times of actual work and struggle, lives in a world of dreams, rather than of fact, and a world of dreams that is organized about desires whose success and frustration form its stuff.
