Immanuel Kant is famous. You’ve probably heard of him. And you know some of his ideas, such as the categorical imperative, or have at some point started the Critique of Pure Reason (if you’re like me, you never finish it). But what do you know about his biography? I may not be able to complete a Critique of Pure Reason, but I did read Manfred Kuehn’s Kant: A Biography in the winter of 2002. From that I learned one surprising fact: Immanuel Kant in his personal beliefs was not an orthodox Christian, if he had religious sentiment at all. This surprised me because I had read elsewhere in passing that Kant was a Pietistic Lutheran. Ultimately whether Kant was religious or not was not a major issue for me, but I did update my personal factual database.
Fast forward six years to 2008. I was at a party kicking back with some philosophers (as in, people completing their doctorates), and it came up that one of them was doing their dissertation on some of Kant’s ideas. This individual happened to be Roman Catholic, and was trying to work in some religious thought. I expressed curiosity, and mentioned offhand how Kant himself was irreligious. My interlocutor expressed surprise and corrected my confusion, explaining that Kant was a devout Lutheran Christian. I shrugged and accepted the correction. I had only read one biography on Kant, and I wasn’t going to make a stand on the views of one scholar (especially when as I said I didn’t really care).
