As an engineer, I am both inspired and troubled by Taft Broome's story. In the final analysis, it matters little- to me if the ethics praxistic employed by Broome when confronting the Concrete Sumo was grounded in western ethics or the virtues of the Mutumin Kiri, though I suspect it is influenced by both. What matters is that the young Broome got it right, at least in the concrete. I am troubled, however, by the telling of the story, which leads me to conclude that, in the abstract, Broome's analysis has one critical flaw.
