The book ‘Metaphysics as a Guide to Morals’ is written by Iris Murdoch. ‘Metaphysics as a Guide to Morals’ is a profound work that analyzes the relationship between religion and morals, moral philosophy, and the metaphysical systems that have supported it. Murdoch shows an ongoing debate with major writers, thinkers, and theologians from Augustine to Wittgenstein, Shakespeare to Sartre, and Plato to Derrida to sustain fresh and compelling answers to these crucial questions.
