In this talk, I survey the origins of connexive logic, focusing on figures including Aristotle, Chrysippus, and Boethius, as well as some more recent approaches, and examine relations between them. I will argue against certain &#8220;deflationary&#8221; readings of early connexivists, but also highlight respects in which early connexivists have sometimes been misunderstood by their modern counterparts.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract: Connexive logics form a heterodox family of systems characterized by contra-classical principles of conditionality and negation including so-called Aristotle&#8217;s and Boethius&#8217; theses.
