Precursors Of Category Theory • 1

A few years back I began a sketch on the Precursors of Category Theory, aiming to trace the continuities of the category concept from Aristotle, thorough Kant and Peirce, Hilbert and Ackermann, to contemporary mathematical use.  Perhaps a few will … Continue reading

Icon, Likeness, Likely Story, Likelihood, Probability : 3

Re: Peirce List Discussion • Phyllis Chiasson A more complete excerpt and the translator’s notes are very helpful here. A probability (εικος) is not the same as a sign (σηµειον).  The former is a generally accepted premiss ;  for that which … Continue reading

Re: Peirce List Discussion • 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
