Jacques Derrida is one of the most influential figures in contemporary philosophy. Yet, Derrida has undermined the accepted rules of philosophy, rejected its methods and concepts, disrupted its boundaries and contaminated philosophy with other kinds of writings. Derrida's approach is an initially puzzling array of oblique, sliding and yet rigorous tactics for destabilising texts, meanings and identities. Deconstructions as these strategies have been called, has been reviled as a politically pernicious nihilism and celebrated as a liberatory politics of choice and difference.
