Johann Georg Hamann (August 27, 1730, Königsberg – June 21, 1788, Münster) was an important German philosopher, a main proponent of the Sturm und Drang movement, and associated by historian of ideas Isaiah Berlin with the Counter-Enlightenment. He was Pietist Lutheran, and a friend (while being an intellectual opponent) of the philosopher Immanuel Kant. He was also a lutenist, having studied this instrument with Timofey Belogradsky (a student of Sylvius Leopold Weiss), a Ukrainian virtuoso then living in Königsberg. He was known by the epithet Magus im Norden ("Magus of the North").
His distrust of reason and the Enlightenment ("I look upon logical proofs the way a well-bred girl looks upon a love letter" was one of his many witicisms) led him to conclude that faith in God was the only solution to the vexing problems of philosophy.
