Human Nature
Debates over the nature of human nature have characterized social theory since it emerged in the Renaissance. As Thomas Sowell has argued, these debates generally take two forms: the optimistic and the pessimistic (Sowell 1987). The former position, associated with Rousseau and anarchists such as William Goodwin, holds that humans are essentially good but are turned bad by the institutions of their society. The latter position is rooted in the assumption that humans are fundamentally egoistic and selfish, thereby requiring either a strong state to regulate them or, in a less pessimistic account, an institution like the market to guide their affairs toward an optimal result.
For sociologists, neither position became the dominant way of thinking about human nature; instead, the plasticity of human experience was emphasized.

We are, in short, what we make ourselves. This version of a flexible approach to human nature would come to characterize contemporary theorists such as Parsons, who spoke of "much discussed 'plasticity' of the human organism, its capacity to learn any one of a large number of alternative patterns of behavior instead of being bound by its generic constitution to a very limited range of alternatives" (1951, p.
