The way an individual's psychology is intertwined with their morality is the subject of this fascinating book from the pen of the late Ilham Dilman.
Dilman convincingly argues that evil, though it cannot be reduced to psychological terms (it is a moral concept) is explicable in terms of an individual person's psychology. Goodness, by contrast, comes from the person and not their psychology.
Philosophers the world over will want to read this book and see how Dilman skilfully defends his arguments.
"The work is an important and insightful contribution to moral philosophy. Dilman's ideas have a long philosophical and , indeed religious lineage, but they are put forward with impressive argumentation, drawing upon philosophy, psychology and literature. No more modern and sophisticated a philosopher has tackled the themes that Dilman develops" - Herbert Morris, UCLA
