This paper deals with certain positions held by Karl Popper in various logical papers dated from 1946 to 1948, which were the basis of his introductory courses on logic and the scientific method held at the London School of Economics for over two decades (1946-1969). There, he developed a metalinguistic theory of deducibility relations, characterized by purely structural rules, which were the basis for providing (what we could call) inferential definitions for the logical constants. First, I will try to situate Popper’s investigations within general logical research, and then I will focus on his treatment of negation and implication, exploring various notions and providing some details for the results that he himself only sketched out.

Abstract
This paper deals with certain positions held by Karl Popper in various logical papers dated from 1946 to 1948, which were the basis of his introductory courses on logic and the scientific method held at the London School of Economics for over two decades (1946-1969). There, he developed a metalinguistic theory of deducibility relations, characterized by purely structural rules, which were the basis for providing (what we could call) inferential definitions for the logical constants. First, I will try to situate Popper’s investigations within general logical research, and then I will focus on his treatment of negation and implication, exploring various notions and providing some details for the results that he himself only sketched out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
