Nilanjan Das at the Formal Methods seminar this Friday

Nilanjan Das (University College London) will present at the Formal Methods this Friday, November 16th, on:

Externalism and Exploitability

Abstract: According to Bayesian orthodoxy, an agent should update – or at least should plan to update – her credences by conditionalization. Some have defended this claim by means of a diachronic Dutch book argument. They say: an agent who doesn’t plan to update her credences by conditionalization makes herself vulnerable (by her own lights) to a diachronic Dutch book, i.e., a sequence of bets which, when accepted, pose a risk of monetary loss without any possibility of monetary gain. Here, I will argue that this argument is in tension with an attractive conception of evidence: namely, evidence externalism, i.e., the view that an agent’s evidence can entail non-trivial propositions about the external world.

Weng Hong Tang (National University of Singapore) will present at the Formal Methods this Friday, November 9th, on:

Reliabilism and Imprecise Credences

Abstract: According to the process reliabilist, a belief is justified if and only if it is produced (or sustained) by a reliable process or system of processes—that is, one that tends to produce a high ratio of true to false beliefs. Given, however, that beliefs are not merely all-or-nothing—given that they come in degrees—a natural question arises as to how the reliabilist may account for justified degrees of belief or credences. Unlike all-or-nothing beliefs, credences do not in general admit of truth or falsity. But like all-or-nothing beliefs, they may be justified or unjustified. Recently, reliabilist accounts of justified credences have been put forward by Dunn (2015), Tang (2016), and Pettigrew (forthcoming). But such accounts focus on precise credences. In this talk, I explore how the reliabilist may deal with imprecise credences.

“Belief models, aggregation and impossibility”

Friday Oct 12th – 14:00-16:00
Room 508, Philosophy Building

Abstract:
The “Belief Models” framework is a very general formal theory of rational belief. It encompasses propositional logic belief sets, but also ranking functions and lower previsions (i.e. lower probabilities). De Cooman (2005) shows that AGM-style expansion and revision operators can be defined in this framework. In this paper I will discuss aggregation of belief models, and draw some connections to various well-known impossibility results for aggregation.
