### A Couple of Talks in Vienna

#### Posted by David Corfield

I’m in Vienna to give a couple of talks, one yesterday and one later this afternoon. Draft slides of both talks are on this page.

The first sees me take up again the work of Michael Friedman, in particular his Dynamics of Reason. I see that I was lamenting the difficulty of getting my original article published back in 2007. (But then I was still a couple of months away from finding out that I had a permanent job after a very long search, and so evidently fed up.)

In any case, I think the story I’m telling is improving with age - we now appear to have modal homotopy type theory and M-theory in harmony. But irrespective of whether Urs Schreiber’s Hypothesis H bears fruit, there’s still an important story to tell about mathematics modifying its framework.

The second talk introduces ideas from my forthcoming Modal homotopy type theory: The prospect of a new logic for philosophy.
