The Polish Association of Logic and Philosophy of Science invites submissions for presentations at the Polish Congress of Logic at the Nicolaus Copernicus University in Toruń. The Congress will feature various plenary sessions, sections, and workshops, among them the First Symposium on the Languages and Logics of Syllogistics (SYLLOS1). It welcomes formal, philosophical and historical contributions on syllogistics in a broad sense, encompassing for example Aristotle’s original proposal, Hellenic and medieval developments and contemporary approaches, both for and against syllogistics. The symposium aims to bring together scholars interested in combining history, philosophy and formal developments to gain new insights into syllogistics.
