@PeterBoettke @BrianCAlbrecht @tylercowen My argument since the 1990s has been that Hayek introduces a novel conceptual breakthrough building upon Wittgenstein and Wittgestein's new concept of the tautology/contingency dichotomy with his 1937 paper "Economics and Knowledge". It's something new and it comes via L.W.

@PeterBoettke @BrianCAlbrecht @tylercowen This is revolutionary "break on through to the other side" development of the neo-Kantian imperative to fully separate & isolate apart the purely logical from the purely contingent/empirical in our thinking, a push coming inside economics from Schmoller & Lowe, and from without.

@PeterBoettke @BrianCAlbrecht @tylercowen I agree that elements of this method appear also in Knight and Mises (and also Marshall). If you will recall, I was the one who sent you the passages where Knight, Mises, and Marshall all use the method.

@PeterBoettke @BrianCAlbrecht @tylercowen The scientifically and philosophically revolutionary thing that takes place in the work of Wittgenstein, Hayek, and Kuhn is a new conception of how we share the common significance our "purely logical" conceptual systems and how we understand them as mapping on to .. 1/2

@PeterBoettke @BrianCAlbrecht @tylercowen .. a conceptually open-ended world & a world of contingent causes of which our thinking, explaining and defining of things is a part. Mapping the logic of one person's planned use of goods isolates explanatory elements outside of this logic, such as learning & rule following. 2/2
