Rich,

I changed the title of this thread to distinguish it from the previous topic.

He published many articles during his lifetime. The best introduction to his work is the following book, which presents his mature philosophy in one set of lectures (with an introduction by Hilary Putnam):

Peirce, Charles Sanders (1898) _Reasoning and the Logic of Things_,

The Cambridge Conferences Lectures of 1898, ed. by K. L. Ketner,

Harvard University Press, Cambridge, MA, 1992.

The following web site, which Pat mentioned, has a few of his early papers:

There are many volumes of his collected papers, but the best papers have been collected in two reasonably priced volumes:

Peirce, Charles Sanders (EP) _The Essential Peirce_, ed. by

N. Houser, C. Kloesel, and members of the Peirce Edition Project,

2 vols., Indiana University Press, Bloomington, 1991-1998.

Volume 1 contains papers written (and mostly published) before 1893, and Vol. 2 contains papers after 1893. (Each vol. costs 26ドル.96 at

Amazon.)

Those books do not contain his mathematical writings, which were published in 4 volumes and are currently out of print.

For existential graphs, I added some commentary to a short manuscript (MS 514), which Peirce wrote as a tutorial:

Frithjof Dau has a very thorough list of pointers to as much as he could find on the WWW by Peirce and others about existential graphs and related topics (including some photographs of the manuscripts):
