Charles Peirce famously divided all signs into icons, indices and symbols. The past few decades have seen mainstream analytic philosophy broaden its traditional focus on symbols to recognise the so-called essential indexical. Can the moral now be extended to icons? Is there an “essential icon”? And if so, what exactly would be essential about it? It is argued that there is and it consists in logical form. Danielle Macbeth’s radical new “expressivist” interpretation of Frege’s logic and Charles Peirce’s existential graphs (...) are mobilized in support of this claim. (shrink)

Recent attention given to the upstart movement of experimental philosophy is much deserved. But now that experimental philosophy is beginning to enter a stage of maturity, it is time to consider its relation to other philosophical traditions that have issued similar assaults against ingrained and potentially misguided philosophical habits. Experimental philosophy is widely known for rejecting a philosophical reliance on intuitions as evidence in philosophical argument. In this it shares much with another branch of empiricist philosophy, namely, pragmatism. Taking Kwame (...) Anthony Appiah's forthright and cautious endorsement of experimental philosophy as my model, I show that experimental philosophy and pragmatist philosophy share more than adherents of either philosophical method have yet to allow. I then use this comparison to show how the new experimentalisms could benefit from a rereading of century-old pragmatist insights about philosophical methodology. (shrink)

This paper contrasts the scholastic realisms of David Armstrong and Charles Peirce. It is argued that the so-called 'problem of universals' is not a problem in pure ontology (concerning whether universals exist) as Armstrong construes it. Rather, it pertains to which predicates should be applied where, issues which Armstrong sets aside under the label of 'semantics', and which from a Peircean perspective encompass even fundamentals of scientific methodology. It is argued that Peirce's scholastic realism not only presents a more nuanced (...) ontology (distinguishing existence and reality) but also illuminates why scholastic realism is a position worth fighting for.

Twenty-three years ago Robert Ayers noticed several brief and intriguing comments on miracles in the Collected Papers of Charles Sanders Peirce. Working with just those scraps of information from the CP, he stitched together a rough but helpful starting point for understanding this aspect of Peirce's religious and scientific thought. In the last few years several more articles on this subject have been written, each filling in a gap left by the others: Ayers' is a theological view, based solely on (...) the CP; later articles fill out Peirce's mathematics and his logic. This paper attempts to fill in a genealogical gap by showing how his thought on miracles is directly related to his dialogues with Plato, Hume, and Lutoslawski. My resources are largely unpublished manuscripts, many of which are fragmentary. I show the relationship between these manuscripts and two key published essays, "Philosophy and the Conduct of Life", and "On the Logic of Drawing History from Ancient Documents, Especially from Testimonies", and then show how Peirce, in dialogue with Plato, exposes and overcomes the nominalistic and anti- miracle prejudices of historiography in his day. The resulting view of history is fallibilistic, realistic and evolutionary, in which miracles are not violations of laws of nature but are to be expected as evolutionary variations that form part of the ongoing self-revelation of the cosmos. Miracles, like all events in history, must not be viewed prejudicially by adherents or detractors, but must be taken into careful account in the grand induction of history and science. (shrink)

A sign is something that refers to something else. Signs, whether of natural or cultural origin, act by provoking a receptive system, human or nonhuman, to form an interpretant (a movement or a brain activity) that somehow relates the system to this "something else." Semiotics sees meaning as connected to the formation of interpretants. In a biosemiotic understanding living systems are basically engaged in semiotic interactions, that is, interpretative processes, and organic evolution exhibits an inherent tendency toward an increase in (...) semiotic freedom. Mammals generally are equipped with more semiotic freedom than are their reptilian ancestor species, and fishes are more semiotically sophisticated than are invertebrates. The evolutionary trend toward the production of life forms with an increasing interpretative capacity or semiotic freedom implies that the production of meaning has become an essential survival parameter in later stages of evolution.
