Even the most violent crowds are never simply an inchoate explosion. There are always patterns, and those patterns always reflect wider belief systems. So the question we have to ask—which ‘contagion’ can’t answer—is, How come people can come together, often spontaneously, often without leadership, and act together in ideologically intelligible ways? If you can answer that, you get a long way toward understanding human sociality. That is why, instead of being an aberration, crowds are so important and so fascinating.”
