Simmel describes society as existing in social "forms" of interaction. These interactions are basically categorized by the characteristically similar types of forms that constitute the form or "type" of societal interaction. Think of all the ways you have interacted with society on a daily basis for the last year. They are really just repeat performances with different characters and details. For instance, going to classes with different professors, with differing teaching styles and techniques. They tend to following similar patterns of lecture, reading, and writing assignments. We know how we are to "act" in the interaction with every professor because we have previously experienced this form of interaction.
Individuals in society are like actors in the never ending play called life. We all play various roles in each interaction we are involved in, and we are all very familiar with the roles and the meanings or significance of the interactions.
How does Simmel use his concepts of the "I" and "me" to describe the way that individuals internalize or feel the influence of society?
