But while associated behavior is, as we have already noted, a universal law, the fact of association does not of itself make a society. This demands, as we have also seen, perception of the consequences of a joint activity and of the distinctive share of each element in producing it. Such perception creates a common interest; that is concern on the part of each in the joint action and in the contribution of each of its members to it. Then there exists something truly social and not merely associative. But it is absurd to suppose that a society does away with the traits of its own constituents so that it can be set over against them. It can only be set over against the traits which they and their like present in some other combination.
