Man is enabled to explore his immediate spaces due to the combined functioning of sensory perception and neuromuscular co-ordination. Relying upon learned redundancies in the world about him and being aware of his own physical capabilities, he is able to avoid chaos as he utilizes his space. The senses of vision, audition, and touch successfully co-operate to allow man an orderly manner of movement and to awaken him to the world outside himself. Over the millenia man has established territories to assure himself and his family a place to rest, mate, and rear offspring. Man has erected extensions, or invisible bubbles, of varying dimensions about himself in his dealings with his own as well as with other species. Man is not solely dependent on instinctive processes as are lower orders of animal life; instead he may think abstractly. Due to this capability, man has been able to convert many of his extensions to physically enclosed spaces which he is able to control and organize about his life
