Differential Logic, Dynamic Systems, Tangent Functors • Comment 2

Posted on November 6, 2021 by Jon Awbrey

Re: Differential Logic, Dynamic Systems, Tangent Functors • 1 Seeing as how quasi-neural models and the recurring issues of symbolic vs. connectionist paradigms have come round again, I thought I might revisit work I began initially in that context, investigating … Continue reading →

All Liar, No Paradox • Discussion 1

Posted on October 23, 2021 by Jon Awbrey

Re: Laws of Form • John Mingers JM: Several people have referred recently to the idea that Laws of Form, and particularly Chapter 11 with imaginary logical values, provides an answer to the problems Russell found in Principia Mathematica leading to … Continue reading →

Posted on October 4, 2021 by Jon Awbrey

In the first place there are likenesses or copies — such as statues, pictures, emblems, hieroglyphics, and the like. Such representations stand for their objects only so far as they have an actual resemblance to them — that is agree … Continue reading →
