==Theory of categories==
{{Main|Categories (Peirce)}}

On May 14, 1867, the 27-year-old Peirce presented a paper entitled "On a New List of Categories" to the [[American Academy of Arts and Sciences]], which published it the following year. The paper outlined a theory of predication, involving three universal categories that Peirce developed in response to reading [[Aristotle]], [[Immanuel Kant]], and [[G. W. F. Hegel]], categories that Peirce applied throughout his work for the rest of his life.<ref name="Burch" /> Peirce scholars generally regard the "New List" as foundational or breaking the ground for Peirce's "architectonic", his blueprint for a pragmatic philosophy. In the categories one will discern, concentrated, the pattern that one finds formed by the three grades of clearness in "[[s:How to Make Our Ideas Clear|How To Make Our Ideas Clear]]" (1878 paper foundational to pragmatism), and in numerous other trichotomies in his work.

The following table is compiled from that and later works.<ref>See in "Firstness", "Secondness", and "Thirdness" in [http://www.helsinki.fi/science/commens/dictionary.html ''Commens Digital Companion to C.S.
