From the first appearance of consciousness, a man finds himself a willing being, and as a rule, his knowledge remains in constant relation to his will. He first seeks to know thoroughly the objects of his desire, and then the means of attaining them. Now he knows what he has to do, and, as a rule, he does not strive after other knowledge. He moves and acts; his consciousness keeps him always working directly and actively towards the aims of his will; his thought is concerned with the choice of motives. Such is life for almost all men; they wish, they know what they wish, and they strive after it, with sufficient success to keep them from despair, and sufficient failure to keep them from ennui and its consequences. From this proceeds a certain serenity, or at least indifference, which cannot be affected by wealth or poverty; for the rich and the poor do not enjoy what they have, for this, as we have shown, acts in a purely negative way, but what they hope to attain to by their efforts. They press forward with much earnestness, and indeed with an air of importance; thus children also pursue their play. It is always an exception if such a life suffers interruption from the fact that either the æsthetic demand for contemplation or the ethical demand for renunciation proceed from a knowledge which is independent of the service of the will, and directed to the nature of the world in general. Most men are pursued by want all through life, without ever being allowed to come to their senses. On the other hand, the will is often inflamed to a degree that far transcends the assertion of the body, and then violent emotions and powerful passions show themselves, in which the individual not only asserts his own existence, but denies and seeks to suppress that of others when it stands in his way.
