Paraconsistent Set Theory

John Bell played a pivotal role in my intellectual life. I was first shown the beauty of mathematics at school, by a particularly gifted teacher. Inspired by this, I went up to Cambridge to read the subject. The process was disillusioning. With only few exceptions, the lectures were dull and boring. It was not uncommon for a lecturer to spend an hour writing on the blackboard with his or her back to the audience. Supervisors obviously derived pleasure from solving the problems that I could not solve, but this was with all the emotional engagement of cross-word puzzle solving. The sense of intellectual excitement that I had experienced at school evaporated.
