Recurring questions about relations, especially triadic relations and sign relations, prompt a return to Peirce’s core papers on the logic of relative terms and the mathematics of relations in general. I began a study of his 1870 “Logic of Relatives” in another series of posts and here take up the chapter on relatives in his 1880 “Algebra of Logic”.
