Savage (1967) gives a frank presentation of the problem, noting that his own (1954) classic theory of rational preference serves as a poster-child for the challenge.<br \/>\nFirst is a review of the challenge.<br \/>\nSecond, I comment on two approaches that try to solve the challenge by making surgical adjustments to the canonical theory of coherent personal probability. One approach relaxes the Total Evidence Condition: see Good (1971). The other relaxes the closure conditions on a measure space: see Gaifman (2004). Hacking (1967) incorporates both approaches.<br \/>\nThird, I summarize an account of rates of incoherence; explain how to model uncertainties about logical and mathematical questions with rates of incoherence; and outline how to use this approach in order to guide the uncertain agent in the use of, e.g., familiar, numerical Monte Carlo methods in order to improve her\/his credal state about such questions.<\/p>\n<p style=\"text-align: justify;\">The presentation is based on the recent paper: <a href=\"http:\/\/www.cmu.edu\/dietrich\/philosophy\/docs\/seidenfeld\/What%20kind%20of%20uncertainty%20is%20that.pdf\">SSK, <em>What kind of uncertainty is that?<\/em> The Journal of Philosophy, 2012.<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>On Thursday November 5th 2015, we will have a joint LogiCIC\/LIRa session with Teddy Seidenfeld.
