Random fun fact:
the English plural of "moose" is often comedically debated. In one of a number of languages it's likely to have been borrowed from ( https://www.etymonline.com/word/moose#etymonline_v_18341 ), the plural is "moozoog". Se…
Peirce discusses several senses in which something can be called Real. With any luck, the next thread should talk about those senses, and how they relate to different kinds of logic.

#SemioticsInSTEM
This example can help clarify some of the properties Peirce claimed icons, and sign relations in general should have. For example, an icon’s object may not physically exist (except insofar as you think ideas exist). This is pretty familiar…
So with morphisms as signs in general, I think some audiences might find the idea of a functor to be a better example of an icon. Whether there is a functor between two categories can certainly be immediately apparent, but it can also take…
I want to go back to icons. Another line of thought that can help clarify how these are relevant in STEM fields was Peirce’s later insistence that reasoning was fundamentally diagrammatic (he took diagrams to be a kind of icon). To reason,…
Gustavo Arengas points out in his paper “Category Theory Variations and Proofs of Peirce’s Pragmaticist Maxim” that this definition suggests the idea of something like a morphism from the object to the interpretant. He also points out that…
So, first, a later definition of a sign was that it was a medium for the communication of a Form. Thought of this way, the sign is in a triadic relation with its object, which ‘determines’ it in some sense, and the interpretant, which it d…
The example I want to mention is an icon. The classic example is a representationalist portrait. It’s representationalist, so it resembles its subject, if such a thing exists. If it doesn’t, it resembles what the thing is represented/thoug…
Sign relations are classified according to the phenomenological categories of their components, and their relations. These changed as Peirce experimented with different ideas, but one class got started very early and stayed pretty consiste…
Last time (https://mathstodon.xyz/@4sphere/113897906706123350), I said I’d get more into the point of things. In my attempts to do so, I’ve realized how much other crap I have to introduce first. I’m working on a more systematic introducti…
This is a vast oversimplification, of both scientific practice and semiotics, but it gives a decent intuition of what the parts are, and I’m hoping to springboard off this into more interesting and realistic examples.
So, now I’ve given s…

I like not being an asshole. If, for whatever reason, I don't manage that, please point it out to me and I'll do my best to fix it!
