Interest in Peirce has grown enormously in recent years

"Interest in Peirce has grown enormously in recent years, and estimates of his significance as a thinker continue to run high. His work in logic, algebraical and graphical, has come to be regarded as substantial both for its historical impact and its enduring importance for research. Hilary Putnam expressed his surprise upon discovering "how much that is quite familiar in modern logic actually became known to the logical world through the efforts of Peirce and his students," (4) and W. V. Quine dates modern logic from "the emergence of general quantification theory at the hands of Frege and Peirce." (5) More recently, John Sowa has demonstrated how Peirce's graphical system of logic (his existential graphs) improves on other logics for the representation of discourse, and the study of language generally, and he has used the existential graphs as the logical foundation for his own conceptual graphs, "which combine Peirce's logic with research on semantic networks in artificial intelligence and computational linguistics."
