What might a 'theory of everything' look like? Is science an ideology? Who were Adorno, Horkheimer or the Frankfurt School? The decades since the 1960s have seen an explosion in the production of critical theories. Deconstructionists, poststructuralists, postmodernists, second-wave feminists, new historicists, cultural materialists, postcolonialists, black critics and queer theorists, among a host of others, all vie for our attention. Stuart Sim and Borin Van Loon's incisive graphic guide provides a route through the tangled jungle of competing ideas and provides an essential historical context, situating these theories within tradition of critical analysis going back to the rise of Marxism. They present the essential methods and objectives of each theoretical school in an incisive and accessible manner, and pay special attention to recurrent themes and concerns that have preoccupied a century of critical theoretical activity.
