Horace G. Alexander was a British Quaker teacher and writer, pacifist and ornithologist. Also he was a friend of Mahatma Gandhi. This is Alexander's lecture on the Justice among Nations. The thesis of my lecture is this: Much of the evil we suffer in the world to-day arises from a false conception of the nature of justice. I want to consider, then, what justice really is; what is its value for us in the modern world; and, especially, how it can be applied to our international problems.
