Dear all, To Rick Blute, Robin Cockett and Simon Henry I am very sad to learn that Phil has left us for another world. I knew him from the time he was studying with Jim Lambek, about 50 years ago. I have a good memory of the lively discussions we had in a café in the Mile-End near McGill. He was always eager to discuss new ideas and he had an apparent limitless thirst for mathematics. His book with Lambek, "Introduction Higher Categorical Logic" is a landmark. He created the school of category theory in Ottawa. I owe him a personal debt: a few years ago, he took the initiative of presenting my case to the Jeffery-Willams prize of the CMS, which I won in 2022! Thank you Phil! I wish there is a paradise for mathematicians, so they can continue their research. Phil was a good angel and we need help.

Phil was one of my PhD advisors at the University of Ottawa from 2015-2020 (along with Pieter Hofstra, who also sadly passed away in 2022). He was an extremely kind and supportive mentor in mathematics and in life. I also knew him to be a very caring and conscientious teacher, from when I served as a teaching assistant for his discrete mathematics course (on more than one occasion), and from when I took a graduate course with him on categorical logic. I last saw him in person when I had a post-PhD-defense celebratory dinner at the Green Door restaurant in Ottawa (one of his favourites!), and in recent years I had seen him at various online seminars and conferences. I last spoke to him over e-mail in October, not knowing that that would be the last time we would speak. May he rest in peace. -Jason Parker On Tue, Dec 19, 2023 at 6:36 AM Richard Blute > wrote: It is with great sadness that we convey the news to the category theory community that our good friend and colleague Phil Scott passed away this morning (18th December, 2023) after a long battle with cancer. Phil’s many contributions to category theory are well known. Phil and Jim Lambek essentially invented the field of categorical proof theory with a series of papers that culminated in the book “Introduction To Higher-Order Categorical Logic”, which is still the standard text on the subject. Phil’s research went well beyond these initial works: he made major contributions to theoretical computer science, linear logic, inverse semigroup theory and recursion theory. Those of us who knew him personally will always think of him as a mentor, a friend and a genuinely kind soul.
