I did not know Jerry Fodor at all, personally. But when you spend as much time with someone's work as I did with his, you feel like you did know him.
When I got to MIT in 1987, Jerry had already left, a year before. But his influence was still ubiquitous. There were a lot of older graduate students who were still working with him, and many of those a year before me clearly seemed like they wished they were.
