Information = Comprehension × Extension • Selection 3

Posted on July 26, 2026 by Jon Awbrey

Selection 3 opens with Peirce remarking a critical property of genuine symbols — the class of symbols is not closed under combinations.  In particular, there are logical conjunctions of symbols and logical disjunctions of symbols which are not themselves genuine … Continue reading →

Information = Comprehension × Extension • Selection 2

Posted on July 24, 2026 by Jon Awbrey

Over the course of Selection 1 Peirce introduces the ideas he needs to answer stubborn questions about the validity of scientific inference.  Briefly put, the validity of scientific inference depends on the ability of symbols to express superfluous comprehension, the … Continue reading →

Information = Comprehension × Extension • Selection 1

Posted on June 20, 2026 by Jon Awbrey

I am going to begin with six selections from Peirce’s Lectures of 1866 where he addresses the roles of signs informing sign relations and their relation to the rules of inference governing inquiries. ⁂ ⁂ ⁂ Our first text comes … Continue reading →

Information = Comprehension × Extension • Preamble

Posted on June 16, 2026 by Jon Awbrey

Perhaps the best perspective from which to bring the connection between the theory of signs and the theory of inquiry into its proper focus is Peirce’s own Theory of Information, which he began setting forth in lectures at Harvard and … Continue reading →

Posted on May 23, 2026 by Jon Awbrey

The passages from Aristotle collected in the present and preceding two posts prepare the way to address overarching tasks in Peirce’s Logic of Science, namely, bringing the Theory of Signs and the Theory of Inquiry into their proper relationship and … Continue reading →

Re: Peirce List • Phyllis Chiasson I’m still a bit fuzzy on how Aristotle’s account relates to Peirce’s usage, though I’m pretty sure Peirce must have taken Aristotle’s usage into account, but it does seem that Aristotle drew some sort … Continue reading →

Re: Peirce List • Benjamin Udell • Michael Shapiro Here’s a likely locus classicus for “icon” in its logical sense — A probability (εικος) is not the same as a sign (σηµειον).  The former is a generally accepted premiss;  for … Continue reading →

Survey of Pragmatic Semiotic Information • 9

Posted on May 4, 2025 by Jon Awbrey

This is a Survey of blog and wiki posts on a theory of information which grows out of pragmatic semiotic ideas.  All my projects are exploratory in character but this line of inquiry is more open‑ended than most.  The question … Continue reading →
