I Fought the Law: An Introduction to the Philosophy of Logic (a.a. 2019/20)


Philosophy of logic inquires into fundamental questions regarding the nature, the epistemology, and the methodology of notable formal systems – how are basic logical laws and rules of inference justified? can they be revised and, if so, on which grounds? what makes logical statements true, and how do we come to know them? The course aims at providing an introduction to these traditional topics. Starting from long-standing conundrums and paradoxes, we will move to examine the basic notions and significance of the non-classical systems they generated (esp. intuitionistic, relevant, and paraconsistent logics). Finally, we will get to some lively issues in the contemporary debate – in particular, (i) logical pluralism, i.e. the idea that there might be more than one correct relation of logical consequence, and hence different but equally legitimate sets of logical laws; and (ii) anti-exceptionalism, according to which theory-choice in logic should be carried out just as in science, for logical statements are neither a priori, nor analytic, nor necessary, and logic – after all – does not deserve any privileged position among the other disciplines.
