Speaker(s): Professor Craig Calhoun | The world is given its contours, reality and limits partly by how it is imagined. Creativity, unrealistically ‘utopian’ thought and even the celebration of illusory ‘golden ages’ perform important roles alongside critical analysis of material conditions and practical possibilities. Art, religion, and social movements each play a vital part, though the power of imagination – and failures of imagination - extends even more widely. This lecture is given ahead of this year's LSE Space for Thought Literary Festival, which will be taking place from Monday 22 - Saturday 27 February 2016 with the theme "Utopias".
