 In September 1799, Schlegel left Berlin to join his brother and Caroline again in Jena. He gave lectures on transcendental philosophy at the University of Jena from October 1800 to March 1801, although these were apparently not well-received. (Among those in the audience for some of those lectures was probably Hegel, newly arrived in Jena, but there is considerable dispute about what Hegel—a bitter rival of Schlegel’s for the remainder of his life—may or may not have gained from hearing them.)
