Hegel"s Phenomenology of Spirit is probably his most famous work. First published in 1807, it has exercised considerable influence on subsequent thinkers from Feuerbach and Marx to Heidegger, Kojève, Adorno and Derrida. The book contains many memorable analyses of, for example, the master / slave dialectic, the unhappy consciousness, Sophocles" Antigone and the French Revolution and is one of the most important works in the Western philosophical tradition. It is, however, a difficult and challenging book and needs to be studied together with a clear and accessible secondary text.
