Högre seminariet i filosofi bjuder in till seminarium med Alex Sandgren. Seminariet har den engelska titeln 'Validity not "Validity"'.
Abstract (på engelska):
Kocurek and Jerzak (2020) have recently defended the view, motivated by recent work by Kouri Kissel (2018,2019), that the only non-trivial reading of counterlogicals like (1) is a counterconventional reading according to which the antecedent triggers a shift in the interpretation of the logical vocabulary in the consequent.
(1) If intuitionistic logic were correct, double negation elimination would be invalid.
I want to raise a problem for this view and use it to shed light the nature of logical disagreement and the subject matter of logical discourse. In a nutshell, the problem is that some counterlogical antecedents concern the status of logical facts themselves and, in particular, how logical facts relate to logical our vocabulary. These counterlogicals resist counterconventional interpretations. I will argue that this difficulty points to a number of broader problems with the views and arguments that motivate Kocurek and Jerzak's approach, most importantly the view called 'logical expressivism' and Quine's 'changing the subject' objection to non-classical logic.
