We've all heard about different kinds of laws...but there is a higher order law that often gets overlooked—it's called Natural Law. The idea behind Natural Law is that all humans are born with an innate understanding of what's right and what's wrong, and that laws should be based on morality. In today's world, where there is no shortage of international wars, authoritarian leaders, human rights violations, and more, where and how can Natural Law be applied? On this episode, we speak with Mary Ellen O'Connell, Professor of Law at Notre Dame and an expert on international law. O'Connell has been studying Natural Law over her career, and gives a justification for how it could be applied in scenarios from the Russia vs. Ukraine war, international human rights, and more.
