Immanuel Kant (1724–1804) has been caricatured as a stiff German professor, whose Stoic habits were so predictable that the people of Königsberg, his hometown, could set their clocks by his daily walks.  Kant’s life is best described as a heroic struggle to discover order within chaos or, better, an effort to fix human thought and behavior within it proper limits.  He lived and worked during the Enlightenment, a time when political, religious, and intellectual freedom erupted across the Western world.
