If there are no human rights a priori of government force, how can tyranny be avoided? In the absence of any deontological justification for normative ethics, there is only virtue ethics.
Voltaire once said that “if God didn’t exist we would have to invent him.” Our imaginations are, of course, limited by our evolutionary past. To us, God has to be human-like. God must be benevolent, meaning it’s actions must seek to benefit humans. Why wouldn’t we invent a God like that? We are human-centered by our very nature. We feel that we deserve our self-designated special place in the universe.
