According to Wikipedia: "Georg Wilhelm Friedrich Hegel (August 27, 1770 – November 14, 1831) was a German philosopher, one of the creators of German Idealism. His historicist and idealist account of reality as a whole 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."
