The concept of individual liberty, consistently applied, would seem to have pluralistic implications. For it leaves room for anyone to act as they please within the context of voluntary interpersonal relations, and by its very nature a society consists of a plurality of different types of people with a plurality of traits and preferences. Individualism, when applied to an entire society of people, recognizes the high degree of diversity among individuals, that each individual is fundamentally different from the other in some way. On the other hand, collectivism and the fallacy of holism that is often present in sociological analysis views a society as if it were a singular autonomous individual or as if it is unanimous, hence failing to recognize the the inherently plural nature of human interpersonal relations. The abstractions of group identities obscures the individual and the diversity within a given group and creates false dichotomies that pits each respective group against the other.
