The Big Idea
Permanent peace is not the natural condition of man, which is closer to a state of constant, looming threat. To move beyond mere temporary truces, nations must adopt republican constitutions and join a federation of free states that preserves their independence while enforcing common law. The argument shifts focus from charity to 'right,' particularly the right of hospitality, which allows strangers to visit foreign lands without being treated as enemies. While politicians often prioritize success over morality, the long-term survival of humanity depends on aligning state policy with the transparent principles of public right.
