  We explore the technical details and historical evolution of Charles Peirce's
articulation of a truth table in 1893, against the background of his
investigation into the truth-functional analysis of propositions involving
implication. In 1997, John Shosky discovered, on the verso of a page of the
typed transcript of Bertrand Russell's 1912 lecture on "The Philosophy of
Logical Atomism" truth table matrices. The matrix for negation is Russell's,
alongside of which is the matrix for material implication in the hand of Ludwig
Wittgenstein. It is shown that an unpublished manuscript identified as composed
by Peirce in 1893 includes a truth table matrix that is equivalent to the
matrix for material implication discovered by John Shosky. An unpublished
manuscript by Peirce identified as having been composed in 1883-84 in
connection with the composition of Peirce's "On the Algebra of Logic: A
Contribution to the Philosophy of Notation" that appeared in the American
Journal of Mathematics in 1885 includes an example of an indirect truth table
for the conditional.
