These facts have important implications for social theory.  In the first place, if there is no such thing as a perfect social system, we should stop spinning theories which postulate their existence and direct our energies toward the building of theories which explicitly assume that all human organizations are imperfect systems.  Second, social theorists (and researchers too) should stop trying to find social utility in all the varied behavior patterns of men; they should recognize that many established patterns of actions re thoroughly antisocial and contribute nothing to the general good.  Third, we should expect to find both cooperation and conflict as continuous and normal features of human life and should stop viewing conflict as a pathological or abnormal condition, as is often done in contemporary functionalist theory.  Fourth, we should devote more attention to the causes and consequences of variations in the degree of group integration.  Finally, we must learn to think of distributive systems as reflecting simultaneously system needs and unit needs, with each often subverting the other (1966, p.34).
