 In 1770, at the age of forty-six, Kant was appointed to the chair in logic and metaphysics at the Albertina, after teaching for fifteen years as an unsalaried lecturer and working since 1766 as a sublibrarian to supplement his income. Kant was turned down for the same position in 1758. But later, as his reputation grew, he declined chairs in philosophy at Erlangen (1769) and Jena (1770) in hopes of obtaining one in Königsberg. After Kant was finally promoted, he gradually extended his repertoire of lectures to include anthropology (Kant’s was the first such course in Germany and became very popular), rational theology, pedagogy, natural right, and even mineralogy and military fortifications. In order to inaugurate his new position, Kant also wrote one more Latin dissertation: Concerning the Form and Principles of the Sensible and Intelligible World (1770), which is known as the Inaugural Dissertation.
