With a difference, however, a fundamental difference. When you have an emotion you cannot yourself examine it. Effectively as the mind may work in sections, it cannot with sanity be divided against itself nor long remain so. A feeling cannot be had and examined in the same time. And though the investigator who studies the nature of red does not become red, the investigator who studies the actual emotion of anger does tend to become angry. Emotion is infectious; anger begets anger; fear, fear; love, love; hate, hate; actions, relations, attitudes, when actual, integrate and fuse; as feelings, they constitute the sense of behavior, varying according to a changing and unstable equilibrium of factors _within_ the organism; they are actually underneath the skin, and consequently, to know them alive is to have them. On the other hand, to know _things_ is simply to have a relation to them. The same thing may be both loved and hated, desired or spurned, by different minds at the same time or by the same mind at different times. One, for example, values whiskey positively, approaches, absorbs it, aims to increase its quantity and sale; another apprehends it negatively, turns from it, strives to oust it from the world. Then, according to these direct and immediate valuations of whiskey, its place in the common world of the two minds will be determined. To save or destroy it, they may seek to destroy each other. Even similar positive valuations of the object might imply this mutual repugnance and destruction. Thus, rivals in love: they enhance and glorify the same woman, but as she is not otherwise sharable, they strive to eliminate each other. Throughout the world of values the numerical distinctness of the seats or centers of value, whatever their identity otherwise, keeps them ultimately inimical. They may terminate in the common object, but they originate in different souls and they are related to the object like two magnets of like polarity to the same piece of iron that lies between them. Most of what is orderly in society and in science is the outcome of the adjustment of just such oppositions: our civilization is an unstable equilibrium of objects, through the cooeperation, antipathy, and fusion of value-relations.
