Paradoxes range from the silly (Frederick apprenticed to the pirates till he is 84) to the puzzling (Zeno’s proof that motion is impossible) to the profound (Arrow’s proof that no preferential voting scheme can be entirely satisfactory). Silly is good, and profound is better; so we’ll look at some of each. How do paradoxes arise? What can be done about them? And what can we learn from them.Classes


Robert (Bob) Tredwell‘s mother felt he had never held an honest job. He was, in more or less this order, a steelworker, a gold miner, a philosophy professor, head of Maine’s Emergency Medical Services program, a consultant to the Saudi Red Crescent Society, and an IT worker at Blue Hill Hospital. His interest in paradox was fostered by his first academic job of teaching logic to young women. He and his wife live in Orono and celebrate their wedding anniversary, occasionally, on February 29.
