Hume is unique among philosophers in being more understandable himself than through any of his commentators. Just read Hume. Not that there's any shortage of folks discussing him.

Well, and this is definitely not Spinoza's position, if you thought you could prove that the Abrahamic God exists exactly as described in the Torah and New Testaments, then the answer to the question "How should one live?" would be answered by appealing to the laws handed down directly from that god to human beings via Moses. So that would be one possible link between the questions "Is there a God?" and "How should one live?". Spinoza had a different conception of what God was, but he seems to think also that certain ways of living are to be preferred over others because they align more with the nature of the God that he supposed he had proved the existence of. I cannot possibly do justice to Spinoza's Ethics in a mere philosophy forum, and ultimately you'll have to answer for yourself the question "What, if any, moral implications follow from particular metaphysical systems?" — jkg20
Woke Kantians understand that the thing-in-itself is just another name for God. — Thorongil
I'm not sure why Spinoza chose the title "The Ethics" for his work, but it is above all a work of metaphysics. As far as I understand him, though, he believes that his metaphysical system actually entails ethical conclusions, and I think he was of the Socratic position that all philosophy was ultimately aimed at answering one question: how ought one to live? — jkg20
