Ingmar Persson is a professor of practical philosophy at Oxford University. The main topics of his research related to the problem of how much concepts that seem to be slowly losing their meaning, such as morality, identity, free will, common sense, mean to us today. His most significant works are The Retreat of Reason – A Dilemma in the Philosophy of Life, which explores the question of attitude towards the problems of personal identity, free will and responsibility; And Unfit for the Future, written together with Christina Schuees, which discusses the role of morality in the scientific improvement of the possibilities of human biological development.
