The author argues that Chrysippus and his followers were fully aware of both the truth-value semantics and the proof-theoretical behaviour of the classical logic connectives, and that Chrysippus' logic amounts, actually, to a redundant formulation of classical two-valued logic, understood as a system of rules. From this one can extract several equivalent formulations of classical logic, in natural deduction style, matching modern standards.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783330016613\"\u003e\u003ch3\u003eChrysippus and His Modern Readers I\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783330016613","offer_id":39428639227997,"sku":"9783330016613","price":23.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d14e876c-546b-44db-b62a-d8c6a2ff95de.jpg?v=1776227973","url":"https:\/\/shop.autorenwelt.de\/products\/an-ancient-logic-chrysippus-and-his-modern-readers-i-von-adrian-rezu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
