description
Evidently prepared as an address to the American Academy. CSP mentions that existential graphs were discovered by him late in 1896, but that he was practically there some fourteen years before. The graphs were not invented to serve as a calculus, but to dissect the inferential process. Two puzzles examined with a view toward testing the system of graphs. One puzzle concerns the relation of signs to minds, and of communication from one mind to another. The other puzzle concerns the composition of concepts and the nature of judgment or, antipsychologically speaking, propositions, Signs reality conventions of the system of existential graphs.
