The second selection in /, 56, the second selection in 30, and 3d are from mss. c. 1902, c. 1895, and c. 1893 (CP 2.274-302). a and ,f are from ms. c. 1903 (CP 2.243-52, 254-65). 30 is from the article " Sign " in Baldwin's Dictionary of Philosophy and Psychology 1902 (CP 2.304). The first selection in 30 is from the article " Index" in Baldwin's (CP 2.305, 306).]

  Panyter says:

Peirce presents his form of the theory of signs--the logic of semiotic, Much of the point of view adopted in this course originates with Peirce, although this subject has been taken up and colored by more recent thinkers in this field (and occasiomlly presented in more readable fashion).

Without question, Peirce, the founder of pragmatism, was first to realize the singular character of the triadic relation. His use of bond diagrams for logical thought is prophetic and revealing. His philosophic concepts of Firstness (quality), Secondness (effect), and Thirdness (meaning) are grounded in the properties of monads, diads, triads, respectively. A word of caution -- Peirce's style runs the (deliberate?) gamut from extreme lucidity to perverse obscurity! But for those who like to climb mountains "just because they are there" Charles Sanders Peirce is a man to know.
