I’m sorry, but you’re not a real person. You don’t have your own thoughts, make your own decisions, or control your own actions. If you stand here and argue with me, I can only regard it as the universe arguing with itself. One part of the universe argues and says “A” is true and “B” is false, while another part of the universe declares “B” true and “A” false. The universe declares “A” and “B” to be both true and false, therefore truth is incoherent in this universe. In the absence of a standard outside of the universe, there is no truth for beings who are just another part of this incoherent universe. So, determinist, you’ll have to excuse me if I can’t believe anything you say.
