- What’s your point, it’s obviously too graphical, but perhaps you are driving at something else. Explain?
My aim here is to survey the source from which radiates all our most enlightening graphical systems of logic — from Peirce’s own entitative and existential graphs, to Spencer Brown’s calculus of indications, to John Sowa’s conceptual graphs. The first glimmerings of that evolution go further back than widely appreciated, being especially well marked in Peirce’s 1870 “Logic of Relatives”, as I hope to make clear in time.
