Immanuel Kant was a German philosopher and a bore, which amount to the same thing. In 1724 he was born in Konigsberg, Prussia, and he liked it so much there that he never travelled more than ten miles from it. Instead he lived the life of the mind, which is about eighty-five cubic inches.
Early in his life Kant speculated about things like galaxies being made of stars, and that the solar system might have been formed from a nebula of gas, but he ultimately found these things too useful. Switching to philosophy, he dedicated himself to bridging the gap between those people who believed nothing and those who believed everything. Kant argued that reasoning that something should be true was better than finding out if it actually was. This theory has shaped Western philosophy to this day.
Kant’s most famous contribution to philosophy was the Categorical Imperative. The Categorical Imperative meant either that you should behave as though your actions were to become universal laws, or something else. He was a little fuzzy on that.
Though he didn’t, as some have said, abhor human company, Kant did isolate himself for a decade, which has to count for something. Kant never knew of a woman (or man) and why should he have? He had his Critiques and his identical daily walks. (That the townsfolk set their clocks by his daily passing is a bit of an exaggeration. Just because they could didn’t mean that they did.) He wasn’t unhappy.
The life of Immanuel Kant shows us not much.
