ABSTRACT
Over time, man experienced a development of his basic biological, physical, social, and psychological needs. By the birth of civilization, man had learned to cultivate the soil, live in communities, and fashion weapons for defense. He began by living in caves and using re for defense, with the warmth of the re giving a feeling of security and providing light and protection against hungry beasts. He eventually
adopted crude fortications, houses, and watchmen or guards to sound an alarm in case of attack by wild animals or marauding bands of other humans. Man’s need for security kept pace with his other primal needs.
