We are pleased to announce that on Monday, May 15 at 6.00pm (CET), Tim Maudlin (NYU) will
give the talk Credence—and Chance—Without Numbers (and with the Euclidean Property) as
part of the Lugano Philosophy Colloquia.
This hybrid talk will take place in room A31 Red Building (USI west campus) and online via
Zoom. If you are interested in joining it online, please write to amm.map(a)usi.ch
Here is the abstract of the talk:
Accounts of both rational credence and of objective chance have always confronted
difficulties associated with events that are assigned “probability zero” by the usual
Kolmogorov probability function used to model the situation. One sort of solution
recommends extending the number field used to represent credences and chances to the
surreals or hyperreals. But the correct solution—the solution that always respects the
Euclidean property—is to eliminate numbers from the fundamental representation of credence
and chance altogether in favor of a system of relations. This solution also sheds light on
other paradoxes, such as the Banach-Tarski paradox and the St. Petersburg paradox.
