1982b The Logic Alphabet takes another look at the ClarkMenger tables:
An introduction to Flip Card Logic. Unpublished draft.
1982c Beginning of the first fullyear sabbatical at the Peirce Edition Project.
Along with identifying pages and tables located elsewhere in the Peirce
Papers, tree diagrams were drawn that reconstruct the order in which Peirce
wrote the 950 pages, including many pages of rewrites, that constitute the
the three versions of "The Simplest Mathematics" (MSS 430, 431, and 429).
This work is in preparation for a later volume of the Writings of Charles S.
Peirce and is on file at the Peirce Edition Project.
1983 Negation, interdefinability, and the 16 binary connectives.
Presented as a play in five acts. Unpublished manuscript
1984 The trinomial theorem, triangular coordinates, and equilateral truth tables as the
conceptual frame in which to activate the relational iconicity in Peirce's triadic logic.
Unpublished draft. [See Publication 1991]
1986 The Logic Alphabet and Nadic operators.
Long letter to Theodore Messenger at the University of North Dakota. March 57.
1989 Beginning of the second fullyear sabbatical at the Peirce Edition Project. A
reconstruction was made of the order in which Peirce wrote almost 500
pages, including rewrites, in which the multiple versions of the "Carnegie
Proposal" (L75) were prepared to present the "Minute Logic" as a series of
memoirs. Consequently, it becomes evident that writing the Minute Logic
went through three stages: (1) from the correspondence beginning in the
middle of 1901, (2) to the long chapters written from the end of 1901 well
into 1902, and (3) to the submission of the final version of the Carnegie
Proposal in July 1902. This work is in preparation for a later volume of the
Writings of Charles S. Peirce and is on file at the Peirce Edition Project.
