The CPA was sad to learn that Dr. Kai Nielsen, Professor Emeritus of Philosophy at the University of Calgary, passed away in Montreal on April 7th, 2021. Professor Nielsen was President of the CPA in 1983-84. One of Canada's most prominent social and political philosophers, he was also a valued colleague and mentor, and is remembered for his kindness, generosity, and commitment to the discipline.
