An existential graph is a type of diagrammatic or visual notation for logical expressions, created by Charles Sanders Peirce, who wrote on graphical logic as early as 1882, [1] and continued to develop the method until his death in 1914.
A logical graph is a special type of graph-theoretic structure in any one of several systems of graphical syntax that Charles Sanders Peirce developed for logic.. In his papers on qualitative logic, entitative graphs, and existential graphs, Peirce developed several versions of a graphical formalism, or a graph-theoretic formal language, designed to be interpreted for logic.
The term diagrammatology is often used synonymously with diagrammatics, however diagrammatics tends to be more common place within the fields of Mathematics (especially logic), the sciences and technology.
What is an existential crisis? The idea of an existential crisis is nothing new. The 19th-century Danish philosopher Soren Kierkegaard—considered the father of existentialism—theorized that ...

In Aristotle's logic, categories are adjuncts to reasoning that are designed to resolve equivocations, ambiguities that make expressions or signs recalcitrant to being ruled by logic.
The syntax of his alpha existential graphs is merely concatenation, read as conjunction, and enclosure by ovals, read as negation. [13] If primary algebra concatenation is read as conjunction, then these graphs are isomorphic to the primary algebra. [14] LoF cites vol. 4 of Peirce's Collected Papers, the source for the formalisms in (2) and (3 ...
Meanwhile, Enphase, despite facing these very real again, I'll call them existential crises that we've talked about, their free cash flow has been a little wobbly, but consistently positive, so ...
