A new monographic work of the visiting professor of the University of Belgrade Faculty of Law, Dr Kenneth Einar Himma, entitled „Morality and the Nature of Law“ (Oxford University Press, 2019) was presented within the General Seminar in Amphitheatre VIII (the courtroom) on April 11th 2019. The published work was discussed, but so was another work of the same author that is still in development, which deals with the conceptual relationship between coercion and law. The subject that got the most attention was a chapter of the new book that considers the concept of obligation.
