I want to talk about my friend, John Williamson, who has just passed away.
I hope you will forgive me if I separate my comments…..first paragraph about his professional career…..after that more personal stuff.
Professionally he was: an empiricist who loved developing philosophical logic to an extent that was opaque to idiots like me, he was particularly interested in many valued logic and how it relates to knots. Obviously he was wrong about all that but he was good at chess.
Privately: he was incapable of an ignoble thought…..his very heart beat decency and the world has lost a good man.
