I only now learned that American philosopher Carl Cohen passed away earlier this year, at the age of 92. He was buried at Forest Hill Cemetery in Ann Arbor, Michigan.


I first met Carl in July 2006, when he spoke at a conference about the moral status of animals at the University of Heidelberg. Even though I thought he was dead wrong about animals, his passion for philosophical debate and his genuine appreciation of reasoned disagreement made a lasting impression on me, and shaped how I think about the nature and role of philosophy. He was a true champion of diversity of opinion and did not shy away from opinions that are unpopular. If that is where he thought the best arguments lead, that is where he went. He publicly and forcefully argued against affirmative action in college admissions, and for the right of neo-Nazis to march in Skokie, a Chicago suburb where a significant number of Holocaust survivors lived. Like Socrates and any philosopher worth their salt, he was a troublemaker.


Carl and I stayed in irregular contact, touching base every so often. He took a genuine interest in my work and was generous with encouraging words. I met him again at his home in Ann Arbor, once in 2016, and a second and last time in 2019, when he spontaneously included me in a family get-together. I will never forget his warm hospitality. He was a mensch, and he will be missed by many.
