Origin of the Text

Peirce delivered the third lecture on Thursday, April 9, 1903. It was announced both in the Harvard Crimson and the Harvard Calendar under the erroneous title "The Application of the Category to Pragmatism" ("Category" should have been in the plural), with a pressing invitation to those who missed the second lecture to come and read the manuscript of it before attending the third. A complete draft of MS 308 is found in MS 307, titled "The Categories continued."
