Since the tribe is a large family, it provides its members with much the same material benefits and social advantages that the family provides for its members, for the tribe is a secondary family. What must be emphasized is that, in the context of the tribe, an individual might indulge himself in an uncouth manner, something which he would not do within the family. However, because of the smallness in size of the family, immediate supervision is not exercised, unlike the tribe whose members continually feel that they are under its supervision. In view of these considerations, the tribe forms a behaviour pattern for its members, developing into a social education which is better and more noble than any school education. The tribe is a social school where its members are raised to absorb the high ideals which develop into a behaviour pattern for life. These become automatically rooted as the human being grows, unlike classroom education with its curricula - formally dictated and gradually lost with the growth of the individual. This is so because it is formal and compulsory and because the individual is aware of the fact that it is dictated to him.
The tribe is a natural social "umbrella" for social security. By virtue of social tribal traditions, the tribe provides for its members collective protection in the form of fines, revenge and defence; namely, social protection. Blood is the prime factor in the formation of the tribe, but it is not the only one because affiliation is also a factor in the formation of the tribe. With the passage of time, the differences between the factors of blood and affiliation disappear, leaving the tribe as one social and physical unit, though it remains fundamentally a unit of blood in origin.
