563 succession to private families? Ought the Roman empire at that time to be esteem'd hereditary, because of two examples; or ought it, even so early, to be regarded as belonging to the stronger, or the present possessor, as being founded on so recent an usurpation? Upon whatever principles we may pretend to answer these and such like questions, I am afraid we shall never be able to satisfy an impartial enquirer, who adopts no party in political controversies, and will be satisfied with nothing but sound reason and philosophy.

But here an English reader will be apt to enquire concerning that famous revolution, which has had such a happy influence on our constitution, and has been attended with such mighty consequences. We have already remark'd, that in the case of enormous tyranny and oppression, 'tis lawful to take arms even against supreme power; and that as government is a mere human invention for mutual advantage and security, it no longer imposes any obligation, either natural or moral, when once it ceases to have that tendency. But tho' this general principle be authoriz'd by common sense, and the practice of all ages, 'tis certainly impossible for the laws, or even for philosophy, to establish any particular rules, by which we may know when resistance is lawful; and decide all controversies, which may arise on that subject.
