    He not only added the enclosing sides of a box to the X-part of
    Fig 18.9c. He also, like McCulloch (1965), tells us how to put a
    dot in a quadrant (MS 530: 126).

The Centro Studi Peirce doesn't have a listing for any publication of MS 530:
http://www.filosofia.unimi.it/peirce/index.php/en/published-manuscritps/15-500-600

The Robin Catalogue of Peirce's papers says this about MS 530:

    530. A Proposed Logical Notation (Notation)
    A. MS., n.p., [C.1903], pp. 1-45; 44-62, 12-32, 12-26; plus 44 pp.
    of shorter sections as well as fragments.
    Ethics of terminology. The history of logical terms and notations,
    and CSP's recommendation of "the best algebraical signs for
    logic." On the Stoic division of hypothetical propositions. CSP's
    division of hypothetical propositions. Graphs, algebra of dyadic
    relations, linear associative algebra, nonions.

Harry, Jon A,

Irving Anellis (deceased a few years ago) wrote two brief papers arguing that Peirce deserves credit for the propositional truth table.

"The Genesis of the Truth Table Device" (Abstract, with link to the paper)
https://escarpmentpress.org/russelljournal/article/view/2056

"Peirce's Truth-functional Analysis and the Origin of Truth Tables" (MathArxiv Preprint)
http://arxiv.org/abs/1108.2429

The X arrangement of TT, TF, FT, & FF appears in the second paper, though not the X-dot symbols themselves. I think I've seen the X-dot symbols (or at least something like them), but I can't remember where, so I hope Jon knows. I searched for 'chias*' and 'chiastic' in Collected Papers of CSP, Writings 1–6, and Contributions to 'The Nation', but found nothing. An X arrangement of xy reflecting the values of v & f appears in CP 4, paragraph 260. (CP 4 is entitled _The Simplest Mathematics _, and the paper by Peirce called "The Simplest Mathematics" is in CP 4.227-323).

Hi Harry,

I did my senior thesis on this back in '76 but at lunch now. More later ...

Dear all,

Shook, in his Dictionary of American Scholars, Vol 1 mentions Warren McCulloch “re-discovering, after Peirce, Dot-X, or chiastic symbols giving 16 possible truth-functions of a pair of propositions” (p 1544).

Does anyone know anything about this?

Yours,

Harry Procter
