Heinrich August Ritter (pronounced as /de/; 21 November 1791 – 3 February 1869) was a German philosopher and historian of philosophy.
He was born in Zerbst, and studied philosophy and theology at the University of Göttingen and Berlin until 1815. In 1824 he became an associate professor of philosophy at Berlin, later transferring to Kiel, where he occupied the chair of philosophy from 1833 to 1837. He then accepted a similar position at the University of Göttingen, where he remained till his death. Friedrich Schleiermacher was a major influence in his thinking.[1]
Ritter's chief work was a history of philosophy (Geschichte der Philosophie) published in twelve volumes at Hamburg from 1829 to 1853. This work was the product of a wide and thorough knowledge of the subject aided by an impartial critical faculty, and its value was underscored by its translation into almost all the languages of Europe. He wrote also accounts of ancient schools of philosophy, such as the Ionians, the Pythagoreans and the Megarians.[1]
Beside these important historical works, he published a large number of treatises of which the following may be mentioned:
