From Descartes to Dostoevsky, the debate concerning the relationship between religion and morality has raged for centuries. Can there be a solid foundation for ethics without God? Or would we be consigned to a relativist morality, where "the good" is just a product of societal values or natural selection? In this landmark work, acclaimed philosopher and theologian, Keith Ward, presents a revolutionary new contribution to this discussion. Reflecting on the work of philosophers old and new - including Hume, Mill, Murdoch and Moore - he argues that our conception of morality intrinsically depends on our model of reality. And if we want a meaningful, objective ethics, then only God can provide the solid metaphysical foundations.Carefully structured and written in Ward's famously clear prose, Morality, Autonomy and God will be an invaluable primer for students of theology or philosophy of religion. But more than that, this strident and controversial book is guaranteed to shape philosophical opinion for years to come.
