Welcome, Phscha.
I might suggest that the only way to get to some “ought” from whatever “is” – is to add an “if.” For example:
Given circumstances c, if I want to bring about g, then I ought to (based on the evidence of c) do a, as the most likely effective instrumental action. But that “instrumental ought” is a far cry from the kind of moral ought I assume Hume was addressing. (Is that one of the things that so distressed Kant vis-a-vis Hume?)
Note: not a philosopher, just an interested lay schlock. ![]()
