Georg Wilhelm Friedrich Hegel (August 27, 1770 – November 14, 1831) was a German philosopher, and a major figure in German Idealism. His historicist and idealist account of reality revolutionized European philosophy and was an important precursor to Continental philosophy and Marxism.
Hegel developed a comprehensive philosophical framework, or "system", of Absolute idealism to account in an integrated and developmental way for the relation of mind and nature, the subject and object of knowledge, psychology, the state, history, art, religion, and philosophy. In particular, he developed the concept that mind or spirit manifested itself in a set of contradictions and oppositions that it ultimately integrated and united, without eliminating either pole or reducing one to the other. Examples of such contradictions include those between nature and freedom, and between immanence and transcendence.
