Hume (and others before him I assume, but I know it's at least in "Agrippa's trillema") said something similar but a bit more accurate: you can't get a moral should from what is, empirically/materially speaking. And politics are an extension of ethics. They're all matters of conviction, of belief (and standing behind them shows one's character, ofc). This is why you can be as smart and knowledgeable as possible and still be a total cunt (think Kissinger), because a person can simply not care.

PS. : "Chatting with AI" is, as the kids say, wild.
