In this July 2025 lecture, Tim McIntosh describes moral philosopher Alasdair MacIntyre’s intellectual conversion to a synthesis of Aristotelian ethics and Christianity, best embodied in Thomism. MacIntyre believed that the Enlightenment’s rejection of a teleological basis for doing ethics doomed the project to failure. That failure is manifested in modernity’s concept of morality as rule-based rather than that which helps human beings to flourish and to move toward our ultimate end. McIntosh discusses why Nietzsche was MacIntyre’s surprising “co-belligerent,” arguing that Nietzsche’s critique of the Enlightenment is sophisticated and worth some attention (though his solutions are not). McIntosh explores the power of MacIntyre’s After Virtue: A Study in Moral Theory (University of Notre Dame Press, 1981) and explains how his moral reasoning is meant to be considered in the context of communities, not in individual isolation.
