Seminar Fall 2002
Decision Theory

Adam Elga and Bas van Fraassen

SYLLABUS

  • Sept 18 Probabilistic updating [BvF] OUTLINE AVAILABLE at EXTERNAL LINKS
      How can we describe our opinion; are there rules for managing or updating it in response to new experience?
    • van Fraassen, Laws and Symmetry , Chapters 7 and 13
    Our concern is with subjective probability, but in External Links there is also an Encyclopedia article on alternative interpretations.
  • 25 Reflection Principle [BvF]OUTLINE AVAILABLE at EXTERNAL LINKS
      How likely does it seem to me now that A, on the supposition that it will seem very likely to me tomorrow morning? (Are there criteria for diachronic coherence of opinion?)

  • Nov 20 [BvF] Vague opinion
      Sharp subjective probability is clearly an idealization: our opinion is vague . How shall we represent vague subjective probability?

  • Nov 27 [BvF]Updating vague opinion
      The standard way of changing one's mind, to update on new information, if one's opinion is vague, encounters various puzzles and challenges. Is there a way either to justify it or to modify it so as to give a more realistic description of our practice?

  • Dec 4 [BvF]Irreducible conditional probability
  • Dec 11 [BvF]Probabilistic semantics, subjective semantics
      An argument is *-valid iff any coherent opinion must have the conclusion at least as probable as the conjunction of its premises. Or: iff the conditional probability of the conclusion given the premises must = 1. Or ...?"
