Reason and Value collects fifteen brand-new papers by leading contemporary philosophers on themes from the moral philosophy of Joseph Raz. The subtlety and power of Raz’s reflections on ethical topics–including especially his explorations of the connections between practical reason and the theory of value–make his writings a fertile source for anyone working in this area. The volume honors Raz’s accomplishments in the area of ethical theorizing, and will contribute to an enhanced appreciation of the significance of his work for the subject.
