JA: This paper of Peirce's has always interested me because it's the one of the places where the logic of relations, and mathematical logic in general, really begins to take off. The lion's share of the logical concepts and notations that we actually use today go back to this and other works of Peirce. As far as nuts-&-bolts applications go, the founding ideas of relational database systems trace through Ted Codd directing back to Peirce's work on the logic of relative terms. | JA: This paper of Peirce's has always interested me because it's the one of the places where the logic of relations, and mathematical logic in general, really begins to take off.
