Overall — Durkheim offers good example of a need for some theoretical humility and patience. Very easy to come up with cheap shots ("Completely insensitive in discussion of native American cultures!" — "Ultimately a conservative functionalist!"), but these no more interesting than those that would dismiss Marx because the revolution hasn't happened yet or because the Soviet Union did not function like clockwork.
Focus: what is the conceptual take-away — not because Durkheim said it, but because the ideas are useful.
Question: what should sociology be a science of?
Organic and Mechanical Solidarity.
Question: Why do suicide rates vary?
Social integration matters. Humans as social — our "interior" and "individual" characteristics depend on our social connections.
