Organism and Environment 

In order to understand this fully, it is necessary to go into the physiology of emotional behavior. We are organisms born with senses: the eyes, the ears, nose, tongue, and the body. When the senses are stimulated, a reaction occurs in the organism as a whole. For example, when light falls upon the eye, sight occurs, and this is a reaction. This sight is only seeing a meaningless field of different intensities and varieties of color. Our next step is to make meaning out of what we see. This is done by the intellect, and in doing so, we construct objects and their relationships. Once an object has been constructed, it is interpreted as pleasant unpleasant or neutral. This interpretation is followed by an emotional reaction to what is seen, in the form of a desire, hatred, or fear. This emotional reaction is but a disturbance in the body, created by a hormone that is secreted into the blood that carries the hormone to all parts of the body, causing changes in the activity of different organs in the body. Every emotion is accompanied by muscular tension, among other changes in the body. This tension is experienced as discomfort, which compels an individual to seek the release of tension in action, to obtain what is desired, to get rid of what is hated, or to run away from what is feared. This is the completion of the reaction.
