THE success, last session, of the discussions at the conclusion of each talk in the series ' The Meaning of Ethics,' has prompted further experiment along those lines. The broadcast discussions in the present series will be on familiar social, economic, and philosophical problems. They will take the form of conversations between an expert and someone representing the ordinary listener's point of view. Each week's discussion will, so far as is possible, be related to the provious week's discussion. The whole purpose will be to provoke arguments and discussions among groups and in the home, rather than to attempt any final solution of the problem involved.
