On the 9th September, 2016, in Amsterdam, Professor Kripke spoke at a conference titled “L.E.J. Brouwer, fifty years later.”

Title: Free choice sequences: A temporal interpretation compatible with acceptance of classical mathematics

Abstract: This paper presents a way of supplementing classical mathematics with a motivation for a Brouwerian theory of free choice sequences. The idea is that time is unending, so that one can never come to an end of time, but also indeterminate, so that in a branching time model only one branch represents the ‘actual’ one. This can be random or subject to various restrictions imposed by the creating subject. The fact that the underlying mathematics is classical makes such perhaps delicate issues as the fan theorem no longer problematic. On this model, only intuitionistic logic applies to the Brouwerian free choice sequences, not because of any skepticism about classical mathematics, but because there is no ‘end of time’ when everything about them can be decided.

John Burgess presented the Second Annual Saul Kripke Lecture “The Origin of Necessity and the Necessity of Origin” on November 13th, 2012, Professor Kripke’s 72nd Birthday. John Burgess is John N. Woodhull Professor of Philosophy at Princeton University and recently authored Kripke with Polity Press.

 

In this lecture Burgess discusses something he was not able to explore at length in the book – the necessity of origin hypothesis which is discussed in Kripke’s Naming and Necessity with the example of Elizabeth Windsor and in a long footnote.

Could Elizabeth Windsor have been the daughter of Harry Truman? Could 5 have been a divisor of 29?

Below is a preview, followed by the full 85 min lecture.
