For nearly forty years, Jack, a physics teacher as well as an ethics teacher, has devoted much thought, reading and practical experimentation to the understanding of fundamental moral theory as well as the methods of practical moral education of the secular kind. Morality is marked by many deep puzzles and two particular moral conundrums have particularly interested him, one being the objectivity of moral judgments, and the nature of moral reasoning. A related conundrum is the nature of good government, and whether this is the same as just government.
Part of Jack's own moral education consisted of three and a half years spent in a Japanese concentration camp, where moral justification and just government are thrown into stark relief. In the last ten or fifteen years the answers to all these controversies and paradoxes became clear to him, and he started writing books, partly to clarify his own thinking and partly to offer the solutions to all these manifold philosophical puzzles relating to how all humans make moral judgments and guide their behavior by their moral conceptions.
Being a practical high school teacher as well as a dyed in the wool intellectual he is also a physically active person, a gardener/botanist, and a designer and builder of two distinctive homes; one of these houses he and his lovable wife inhabit in a stunning setting in Nanaimo, British Columbia. He has had much pain in his life but considers himself to be a happy man in having made a positive difference.
