I followed this course by, Dr. Thomas Schiller during my 5th Semester at the ILLC Amsterdam for my M.Sc. Logic (UvA). A full description of the course can be found here. I already followed a course in Philosophy of Logic for which I wrote What a Logic Could not Be connected to the ideas I am writing about in Structuralism & Categories (Research Project). The essay for this course will be available here: Overleaf: TBA.
