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).
Best, Ben

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
