"The aim of a rational ethics should be to maximize freedom and avenues of happiness and to minimize avoidable suffering." In this highly thought provoking and stimulating book, the author, Dr. Ramendra, has briefly and critically discussed the ethical ideas of G. E. Moore, Bertrand Russell, Lokayat, Buddha, Epicurus and John Stuart Mill before expounding his own ideas in a logical manner. The author has convincingly advocated a rational ethics based on human needs and desires.
