Acceptability designates justified or rational believability. In the much-disputed theoretical field on conditionals, the acceptability conditions of conditionals is one of the few topics where some consensus has been reached. Discussing the acceptability conditions of conditionals is to state under which circumstances it is epistemically appropriate to hold a conditional belief. One of the most widely accepted interpretations among philosophers is that the acceptability of a conditional follows from its respective conditional probability. This is one possible reading of E. W. Adams’s thesis, originally formulated as a theory of the assertability of conditionals. In philosophical literature, it is not uncommon to find those who defend the descriptive correctness of Adams's thesis, which implies the correctness of the acceptability conditions entailed by it. For I. Douven, this defense is mistaken, as its rejection can be supported by empirical findings. Results from experimental studies conducted by him and S. Verbrugge suggest that neither Adams’s original thesis nor some of its weakened versions found in the literature are descriptively accurate. This does not imply that the acceptability of conditionals cannot be framed in probabilistic terms; rather, it suggests that the available probabilistic theses require adjustments to establish more accurate descriptive conditions for acceptability. This paper aims to review epistemic theories of conditionals, particularly Adams’s thesis considering the experimental results obtained by Douven and Verbrugge. Accordingly, what is sought is a reflection on the role empirical approaches might assume within the philosophical theorization at hand.Downloads
