Description
Waal p. 168:
In 1964, Jay Zeman showed that with minimal modifications to its rules the gamma graphs can be made isomorphic with the well-known modal logics S4 and S5. See The Graphical Logic of C. S. Peirce (Doctoral Dissertation, University of Chicago, 1964). For C. I. Lewis’s modal logics (S1–S5), see C. I. Lewis and C. H. Langford, Symbolic Logic (New York, 1932).
