Hello Nicholas

I would read more than a joke into this comment

Blaug made it what he calls a rallying cry of the anti-Popperians, and that
seems to me closer to the mark.  Regardless of who said "economics is what
economists do", it neatly sums up, for me, the kind of intellectual
relativism championed by Wittgenstein and his associates.

Which leads me to a observation regarding that somewhat notorious
confrontation between the two parties, Wittgenstein and Popper (the poker
incident)

Has anyone ever pointed out or discussed the curious historical fact that
Popper (certainly) got his professorship through Hayek, and Wittgenstein
(arguably) got his professorship through Keynes?
