Christine Ladd-Franklin's and Victoria Welby's correspondence with Charles Peirce

Abstract

The Peirce–Welby correspondence has been an invaluable source for the historians of logic and semiotics mapping the development of Peirce's thought and of the significs movement. The unpublished Peirce–Ladd-Franklin correspondence provides equally important insights into the development of theories of logic and meaning, science and reasoning, and language and intelligence. Taking Ladd-Franklin's contributions into account puts the received historiography on modern logic, semiotics, pragmatism, and linguistic philosophy in a new light. She was also a pioneer in women's rights in higher education and scientific research.
