Dak and Black,
Which side of the consequentialist/deontological debate do you ascribe to? I only ask because you cite thinkers on both sides, and I'm curious as to which approach you find more credible.
I just picked up my own copy of Kant's Critique of Pure Reason. It's a fucking beast.
I also don't see them as mutually exclusive; the difference simply lies in where one perceives the force of argument, and the methodology used to get there. The ultimate results are the same. Consequentialists seem to take a more inductive approach (i.e. in its vulgar sense: it is likely that a free market will result in more prosperity and equality for all, thus it is good). I actually like the consequentialist formula because it's a bit more scientific/structuralist, or it appears so to me.
The deontological sphere (which would be thinkers like Mises and Rothbard) follows a process of deductive logic from the a priori claim of natural rights. To me, this is more problematic.
The deontological sphere certainly is more problematic on a macro spectrum, but I think that deontologicalism is inherently set to a micro level. This goes back to Mises' argument that one cannot denote human action to a structured scientific formula.
So, are you interested in Hume, or Kant? Or Both? Kant is extremely important because articulates a new direction after the intense skepticism of Descartes and Hume.
I think the consequentialist argument has flaws as well, but I think it sets out to establish its legitimacy based on material conditions, which I find more convincing.
Kant. As I read, it appears that a paraphrase of consequentialism would be "The end justifies the means", and I can't even remotely agree with that, for numerous reasons. On the surface I would say consequentialism may even be inherently intellectually dishonest/bankrupt, as pursuing ends without considering the actual effects of the means (or the effects of the ends, and therefore the end itself in either case) is not intellectual at all.
"We are going to do X to achieve Y." When pressed for how X will achieve Y (or why Y is desirable in the first place), the consequentialist turns to mysticism .
You know that David Friedman is a consequentialist, right?
Those who accept any part of Kants philosophy - metaphysical, epistemological or moral, deserve it.
