In this article, I reconsider the volunteer theory.
The characteristic of the classic volunteer theory is to emphasize the public interest, gratuitousness and spontaneity in the concept of volunteer.
But, the concept of volunteer has been doubted, and those three elements have been
interpreted expansively.
I considered these three elements again from the point of the common relations of the person concerned.
The following points mainly became clear.
Primarily, if we cannot enter the common relations, the doubt to the classic volunteer theory is born.
Second, the expansion of those three elements is the outcome that social structure came to permit the common relations of the person concerned.
Third, now, the volunteer is carried out in interval of the everyday life.
However, I am not able to show how the volunteer forms society while facing power.
I handle this problem in the other article.
