DESCRIPTION:In his pioneering ‘Truth and Probabili
 ty’ (1931), Frank Ramsey sets out an influential a
 ccount of the nature, measurement, and norms of pa
 rtial belief. The centrepiece of this work is a re
 presentation theorem that allows Ramsey to constru
 ct a unique probability function representing an a
 gent’s subjective degrees of confidence. In many w
 ays, this marks the birth of decision theory as a 
 field and the birth of the subjective interpretati
 on of probability. In this expository talk we will
  examine the philosophical background underlying R
 amsey’s goals in this work, we will re-construct t
 he main formal moves Ramsey makes in proving his r
 epresentation theorem and finally, we will critici
 se some of the philosophically contentious assumpt
 ions that permeate throughout ‘Truth and Probabili
 ty’ (1931). Taking a broader perspective, represen
 tation theorems are the underbelly of much work in
  theoretical economics, the underbelly behind clai
 ms like ‘humans are rational’. This talk will give
  a first-hand look at (just) one such representati
 on theorem, but the illustrative purposes this wil
 l serve will hopefully be felt by anyone who is a 
 slave of some defunct economist. Which, if some ar
 e to believed, includes all of us.
X-ALT-DESC;FMTTYPE=text/html:\n  <p>In his pioneer
 ing ‘Truth and Probability’ (1931), Frank Ramsey s
 ets out an influential account of the nature, meas
 urement, and norms of partial belief. The centrepi
 ece of this work is a representation theorem that 
 allows Ramsey to construct a unique probability fu
 nction representing an agent’s subjective degrees 
 of confidence. In many ways, this marks the birth 
 of decision theory as a field and the birth of the
  subjective interpretation of probability. In this
  expository talk we will examine the philosophical
  background underlying Ramsey’s goals in this work
 , we will re-construct the main formal moves Ramse
 y makes in proving his representation theorem and 
 finally, we will criticise some of the philosophic
 ally contentious assumptions that permeate through
 out ‘Truth and Probability’ (1931). Taking a broad
 er perspective, representation theorems are the un
 derbelly of much work in theoretical economics, th
 e underbelly behind claims like ‘humans are ration
 al’. This talk will give a first-hand look at (jus
 t) one such representation theorem, but the illust
 rative purposes this will serve will hopefully be 
 felt by anyone who is a slave of some defunct econ
 omist. Which, if some are to believed, includes al
 l of us.</p>\n
