MOVING TO FRONT FROM DECEMBER 6
A leading figure in cognitive science, whose work was quite important in philosophy as well, Professor Pylyshyn taught for many years at the University of Western Ontaro, before joining Rutgers psychology in 1991, which (with Jerry Fodor and Stephen Stich, among others, in philosophy) had become a powerhouse in cognitive science. I will add links to memorial notices as they appear. Remembrances from those who knew Professor Pylyshyn, or comments on the philosophical significance of his work, are welcome in the comments.
