Men have diverse needs, desires and interests which demand satisfaction. There are three ways of fulfilling these needs.
Firstly they may act independently each in his own way without caring for others. This is unsocial with limitations. Secondly men may seek their ends through conflicts with one another. Finally men may try to fulfill their ends through cooperation and mutual assistance. This cooperation has a reference to association.
When a group or collection of individuals organize themselves expressly for the purpose of pursuing certain of its interests together on a cooperative pursuit an association is said to be born. According to Morris Ginsberg an association is a group of social beings related to one another by the fact that they possess or have instituted in common an organization with a view to securing a specific end or specific ends. The associations may be found in different fields. No single association can satisfy all the interests of the individual or individuals. Since Man has many interests, he organizes various associations for the purpose of fulfilling varied interests. He may belong to more than one organization.
