UPDATE: While I was writing the post below, Levi posted his own take, I haven’t had a chance to read it yet, so if some issues are already addressed, I apologize.
While clarifying what Kantian ethics is really about is a noble task, I would like to point out some things that might have been unclear from my initial post on realism’s possible ethical stance as i cited Kant’s third Critique (§76). I think that Levi’s questions concerning the connection between metaphysics and ethics are legitimate, but are directly addressed in Kant’s corpus – I would even say that Kant is extremely concerned with ethical outcome of any sort of metaphysical exercise and this concern is found throughout his writings. In §76 Kant is basically imagining a different kind of human cognition, the one that lacks the distinction between intuition and understanding/reason, a kind of cognition that would have an immediate knowledge of the actual (things-in-themselves), if I am reading it correctly. Kant’s argument is simple, I think, and consists of very simple steps: human cognition distinguishes between appearance and things-in-themselves as it has knowledge of the former and only posits the latter, if we imagine a cognition that distinguishes between the two yet knows both, the very distinction is then shown to be unnecessary, now we are talking about a thought experiment, only God’s cognition would fit a hypothetical scenario, yet if we take realism and its claim that there is a world out there and (important “and” I think) we have a direct access to it and can know it as it is in itself, then we know things-in-themselves via a sort of “intellectual intuition,” i.e. Kant’s point about heterogeneity of intuition and understanding can be disregarded. I then go on to ask a question: what would the world of things-in-themselves look like if indeed we have direct knowledge of it? Kant states, and again we may or may not agree with his argument, that in such a world things would simply be, simply exists – I thought of such a world as a sort of a nightmare precisely because without space/time (form of intuition, of course) and without potential/actual distinction (being a form of causality, causality being part of mind’s work, not something found in things themselves) life would be a nightmare.
Ok, let’s throw all that Kantian jargon and Kantian arguments out of the window – there’s a lot, I know, so I’m going to give you some time… Continue reading
