This is a reply to a comment to our piece on "Science and Scientificity in the Negatives Denken". It is quite gratifying that our Dan below has referred to Barry Smith's important work relating to the "metaphysics" - not so much of "economics", as Smith seems to indicate, but rather of the Austrian School (there is a huge difference between "economics" and "the Austrian School" - the two are far from identical!). On the metaphysics of capitalism proper, I may refer our friends to the pieces recently posted here (just use the search facility in the top corner)). Many lustres ago I wrote a piece on "The Pure Logic of Choice" (Hayek's phrase for "praxeology") in which I discuss Mises, Hayek and Barry Smith as well as Roderick Long's interpretation of Wittgenstein's relevance to these all-important questions. As soon as I am able, I will post this piece.
