Ultimate Property Rights

Saladin: Who defends?
Imad: Balian of Ibelin, the son of Godfrey.
Saladin: Godfrey? Godfrey nearly killed me in the Lebanon. Truly, I did not know he had a son.
Imad: It was his son at Kerak.
Saladin: The one you let live?
Imad: Yes.
Saladin: Perhaps you should not have.
Imad: Perhaps I should have had a different teacher.

One astute point made by John Locke in his Two Treatises of Government is that each of his is the product of the Creator. Each of us is the Creator's property, furnished with facilities meant to do the Creator's pleasure.

Each is therefore "bound to preserve himself, and not to quite his station wilfully." Thus the right to self-defense.

It therefore follows that people should restrain themselves from "invading others' rights."

While we often speak of the property rights of each individual, the ultimate property rights belong to the Creator.
