Professor Ameriks was well-known for his work on the philosophy of Immanuel Kant, German Idealism, the history of modern philosophy, and Continental philosophy.
He is the author of Kantian Dignity and Its Difficulties (2024), Kantian Subjects: Critical Philosophy and Late Modernity (2019), Kant’s Elliptical Path (2012), Kant and the Historical Turn: Philosophy as Critical Interpretation (2006), Interpreting Kant’s Critiques (2003), Kant and the Fate of Autonomy: Problems in the Appropriation of the Critical Philosophy (2000), and Kant’s Theory of Mind: An Analysis of the Paralogisms of Pure Reason (1982), among many other works, which you can learn more about here.
Professor Ameriks joined the philosophy faculty at Notre Dame in 1973. He earned his PhD and undergraduate degrees in philosophy at Yale University.
Karl was a wonderful person. Brilliant but also humble and kind. He will be greatly missed.
You’re blessed to have known him. I never had the pleasure but benefitted so much from his work.
Karl was my dissertation director, and a friend. I’m sure many will talk about how humble and self-giving he was, which is true. He helped me a great deal on a project that (at the time, at least) was not very close to his own intellectual passions, and he did it with energy, good humor, and emails utterly lacking in capital letters.
But I hope it will also be highlighted just how much fun it was to talk to him. He somehow always had 10-15 things going on in his mind that you would never have expected. Maybe they all ultimately led back to Kant in one way or another, but still… the breadth of his curiosity was intoxicating, and he was the life of every party I ever attended with him.
I’ll miss him.
His emails were poetry, as were his conversations.
Yes, poetry.
The significance and seriousness of Karl’s Kant scholarship goes without saying. But others have mentioned his humility and kindness, and those qualities also made a strong impression on me. I first met Karl at a conference, and was very surprised – about two months later! – when he took the time to look up my email and send me a long and generous note. That led to a small correspondence, and we also met and chatted at a few other conferences. I’ll certainly remember how friendly and supportive he was to a grad student with whom he had no institutional affiliation.
I had a similar experience. I’m not sure I ever had anyone else show as much interest in a conference paper, and doubt anyone else was as encouraging about my project. But I’m positive nobody else ever emailed me to follow up on a conversation we’d had related to a talk about my conference paper weeks later, let alone multiple times. I will miss him.
Karl was kind and generous, well beyond the norm. Supererogatory… despite being a Kantian 😉
The last time I saw him not too long ago was in the Notre Dame Credit Union on campus, and my wife and I had a friendly, longish conversation with him.
And he was a great dissertation advisor.
I’ve been very sad to learn about Karl’s passing. While I wasn’t blessed to be close with Karl–he’d gone emeritus by the time I was midway through the PhD program at Notre Dame–I was fortunate enough to have chatted with him at times, to have listened to him talk on more occasions, and to have had him as a committee member for my oral examination. Here’s one of the questions I remember him asking during my exam: “So, what did, y’know, what did they think about personal identity?” I was caught off guard, and replied something along the lines of, “They? Like, all of them? What did each of them think constituted personal identity?” He replied, “Well, yeah!”, leaning back in his chair, probably with his hands folded over his midsection. (I can see him in my mind now!) But I was prepared, so I rattled off the individual theories of all eight of the 17th and 18th century philosophers on my reading list. His question, broad though it was, gave me confidence, since I thought, “If I can answer that, heck, I’ll be ok!” Karl’s voice was amazing, too. He had this cheerful and funny way of talking, as if life was at once deep and enjoyable but also delightfully funny. I used to do a Karl impersonation in grad school, because I loved hearing his voice, even if only in my head. If you’ve had even one conversation with him, you’ve been blessed in a number of ways.
He definitely had a unique voice and style.—which I loved. Someone once said that visiting him to discuss ideas was like visiting a Zen master: you weren’t entirely sure what you might get.
Here’s my idiosyncratic memorial essay, for whatever it’s worth.
