¿Shifting Paradigms? • 6

Posted on October 17, 2017 by Jon Awbrey

Re: Peter Cameron • Infinity and Foundation C.S. Peirce is one who recognized the constitutional independence of mathematical inquiry, finding at its core a mode of operation tantamount to observation and more primitive than logic itself.  Here is one place … Continue reading →

Re: Peirce List Discussion • GF • JFS When it comes to the relative contributions of phenomenology and mathematics to logic, I always find myself returning to the picture I drew once before from Peirce’s Syllabus, on the relationship of phenomenology and … Continue reading →

Minimal Negation Operators • 4

Posted on September 1, 2017 by Jon Awbrey

Note.  I’m including a more detailed definition of minimal negation operators in terms of conventional logical operations largely because readers of particular tastes have asked for it in the past.  But it can easily be skipped until one has a … Continue reading →

Minimal Negation Operators • 3

Posted on August 30, 2017 by Jon Awbrey

It will take a few more rounds of stage-setting before we are able to entertain concrete examples of applications but the following may indicate the direction of generalization embodied in minimal negation operators. To begin, let’s observe two ways of … Continue reading →

Re: Minimal Negation Operators • 1 The brief description of minimal negation operators given in the previous post is enough to convey the rule of their construction.  For future reference, a more formal definition is given below. Initial Definition The … Continue reading →

Minimal Negation Operators • 1

Posted on August 27, 2017 by Jon Awbrey

To accommodate moderate levels of complexity in the application of logical graphs to practical problems our Organon requires a class of organules called “minimal negation operators”.  I outlined the history of their early development from Peirce’s alpha graphs for propositional … Continue reading →

Charles Sanders Peirce, George Spencer Brown, and Me • 10

Posted on August 25, 2017 by Jon Awbrey

With any formal system it is easy to spend a long time roughing out primitives and reviewing first principles before getting on to practical applications, and logical graphs are no different in that respect.  But the promise of clearer and more … Continue reading →
