The Social Contract or Principles of Political Right. Book IV
Chapter IX. Conclusion
NOW that I have laid down the true principles of political right, and tried to give the State a basis of its own to rest on, I ought next to strengthen it by its external relations, which would include the law of nations, commerce, the right of war and conquest, public right, leagues, negotiations, treaties, etc. But all this forms a new subject that is far too vast for my narrow scope. I ought throughout to have kept to a more limited sphere.
