What do we feel when part of a crowd? Fear or empowerment? Do we lose ourselves or find our real selves? Is a crowd a mob, an ignorant mass of unthinking beings? Or is it an intelligent body, capable of thought processes and invention of which individuals alone would not be capable? We spend much of our life in crowds: atthe football, a concert, crossing the street at peak hour, as we worship, mourn, protest or feast, we often do so as part of a crowd. The Crowd examines the nature of the crowd, in its many manifestations, both human and in the natural world.
