7- And finally some say that discovering this concept that why man has intended to social life since millions of years ago when man is created, is not possible. Because, lapse of centuries and ages has obscured this and similar issues and we do not have sufficient documents available for judging in this respect.

Although the recent view seems more realistic than the other opinions and judgments about the main cause of man's attention to the society in the past is not an easy task, but obviously first of all, present continuation of this social life is indebted to "desire in perfection" and "development of man's requirements" and "disability in fulfilling them".

It should be explained that on one hand man sees that his corporeal requirements including cloth, food, house, medicine, and his spiritual requirements, including sciences, knowledge, training, various tastes and initiatives, and feeling spiritual security and attracting others' affections are so extensive and numerous that it is not possible for one to fulfill all of them alone.

Rather, supplying each of these requirements, according to the fastidious nature of human, should be performed by the individuals and groups being proficient and skillful in their task.

And on the other hand, man's escape from monotony and uniformity of life and willing to a better and more perfect life,–the features of man's life, which are rarely found in the animals, make him to join social life, because this objective is not possible unless thanks to the accumulation of different thoughts, powers and talents. These two are the most important factors making man to continue his social life.

Social value Although, all people are the same in all regulations in view of social rights, and the principle of equity before law is one of the most basic foundations of progressive legal rules, but observance of this principle does not account that value of individuals is actually equal in the society. Rather, it is mostly due to unavailability of any other way for preserving discipline and preventing misuses of the arrogant and influential classes and colonization of man by man.

Otherwise, it is undeniable that social value of individuals is very different. For example, the existence value of a resourceful, gracious and competent scientist is never equal with an illiterate, improvident and vicious person.
