Lewis and G\u00e4rdenfors taught us that the Test clashes with AGM-style qualitative belief revision as well as Bayesian conditionalization for credences. But it has been long been spotted that AGM and conditionalization can govern <em>indicative<\/em> supposition (What is the case if A is the case?), not subjunctive or <em>counterfactual<\/em> supposition (What would be\/have been the case if A was\/had been the case?). And if, as has also been proposed, the latter is governed by (a) KGM (Katsuno-Grahne-Mendelzon)-style belief revision (which can be recaptured in modal-epistemic logic) in a qualitative setting, and (b) Lewisian imaging for credences \u2013 then everything falls into place: we have Ramsey Tests mapping the standard Lewis-Stalnaker variably strict counterfactual conditional to such revision procedures (a) and (b). Moreover, as shown in this talk, (a) and (b) are essentially the <em>same<\/em> procedure, declined in a qualitative and probabilistic setting respectively. And this neat package is evidence that we assess counterfactuals by subjunctive supposition, in a perfectly consistent way.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Franz Berto (University of St Andrews)<br \/>\nDate and Time: Thursday, May&nbsp;22nd 2025, 16:30-18:00<br \/>\nVenue: ILLC Seminar Room F1.15, Science Park 107 and\u00a0online.<br \/>\nTitle:\u00a0Counterfactual Supposition.<br \/>\nAbstract.
