I’ve been calling attention to what Peirce wrote about the “Doctrine of Individuals” (what we’d probably call a theory of individuals) for quite some time. Just for starters, here’s a few entry points I was able to find right off.
- Conceptual Graphs List • (27 Nov 2000)
- Peirce List (Feb–Mar 2015) • (1) • (2) • (3) • (4)
- Mathematical Demonstration and the Doctrine of Individuals • (1) • (2)
To my mind this constitutes one of the most far-reaching insights in all of the thought Peirce passed on to us, making as it does a turn from the dead hand of absolute ontology to the rather more handy and pragmatic tack of discourse-relative ontology and interpretive information theory.
