Larry May is professor of philosophy at Washington University in St. Louis and Research Professor of Social Justice, Centre for Applied Philosophy and Public Ethics, Charles Sturt and Australian National Universityies. He is the author of numerous books, including The Morality of War; Crimes Against Humanity, which won an honorable mention from the American Society of International Law and best book award from the North American Society for Social Philosophy; and War Crimes and Just War, which won the Frank Chapman Sharp prize for the best book on the philosophy of war from the American Philosophical Association.

"Philosopher Larry May delivers a ground-breaking reassessment of what the Nuremberg Tribunal had identified as the 'supreme international crime.' Building upon his paradigm-shifting work on crimes against humanity and war crimes, May now reorients the debate regarding the scope and merits of criminalizing aggressive war. Especially noteworthy is his contention that aggression should be defined as a first wrong that violates human rights. May combines reason with creativity - and sophistication with accessibility - to offer a tour-de-force with interdisciplinary appeal to a wide audience."-Mark Drumbl, Washington & Lee University School of Law
