““Roles appear as soon as a common stock of knowledge containing reciprocal typifications of conduct is in process of formation, a process that, as we have seen, is endemic to social interaction and prior to institutionalization proper. The question as to which roles become institutionalized is identical with the question as to which areas of conduct are affected by institutionalization, and may be answered the same way. All institutionalized conduct involves roles. Thus roles share in the controlling character of institutionalization. As soon as actors are typified as role performers, their conduct is ipso facto susceptible to enforcement. Compliance and non-compliance with socially defined role standards ceases to be optional, though, of course, the severity of sanctions may vary from case to case. The roles represent the institutional order.38 This representation takes place on two levels. First, performance of the role represents itself. For instance, to engage in judging is to represent the role of judge. The judging individual is not acting “on his own,” but qua judge. Second, the role represents an entire institutional nexus of conduct.””
