Johann Friedrich Flatt (20 February 1759 – 24 November 1821) was a German Protestant theologian and philosopher.

Life

Johann Friedrich Flatt was born in Tübingen. His brother, Karl Christian Flatt (1772–1813), was also a theologian. He studied philosophy and theology in Tübingen, afterwards continuing his education in Göttingen. In 1785 he became a professor of philosophy at the University of Tübingen, where in 1792 he was appointed an associate professor of theology.^[1] In 1798 he succeeded Gottlob Christian Storr (1746–1805) as a full professor of theology at Tübingen.^[2]

He was a disciple of Gottlob Christian Storr, and like his mentor, a representative of the so-called Ältere Tübinger Schule (conservative Tübingen school of theologians) of Biblical Supranaturalism. He is remembered as a defender of Christian moral theology, and for his critical lectures in regard to Kantian philosophy.^[1][2]

Along with Friedrich Gottlieb Süskind, he was an editor of the "Magazin für christliche Dogmatik und Moral" (Magazine of Christian Dogmatics and Morals).^[2]
