The founder of modern political philosophy is Machiavelli. He tried to effect, and he did effect, a break with the whole tradition of political philosophy. He compared his achievement to that of men like Columbus. He claimed to have discovered a new moral continent. His claim is well founded; his political teaching is "wholly new." The only question is whether the new continent is fit for human habitation.
