Peirce’s Triadic Logic: Continuity, Modality, and L
In 1909, in his Logic Notebook, Charles Sanders Peirce conducted what appear to be the first experiments with many-valued logic. As these experiments are entirely contained within a handful of pages in his notebook, which were not published or discussed by other authors during his lifetime, little is known about his reasons for conducting this research. By examining and transcribing these pages, and connecting them to his larger body of philosophy, I show how his motivations lie within his views on modality and continuity.
