[FRIAM] Ramsification and Semantic Indeterminacy

[Pieter Steenekamp]

Different strokes for different okes, indeed. In my realm of AI — and
previously in control systems — fuzzy logic has been the trusty spanner for
tackling vagueness. Seeking a fresh perspective, I turned to ChatGPT, which
delivered this thoughtful comparison:

"Ramsey semantics and fuzzy logic both grapple with vagueness but chart
fundamentally different courses. Ramsey semantics clings to the rigorous
shores of classical logic and binary truth values (true/false), navigating
semantic indeterminacy by emphasizing the roles terms occupy rather than
insisting on their precision, making it a philosophical and theoretical
endeavor. Meanwhile, fuzzy logic boldly abandons binary constraints,
introducing gradations of truth (e.g., 0.3 or 0.7), rendering it an elegant
mathematical tool for practical domains like control systems and AI. Where
Ramsey semantics contemplates the hazy edges of meaning, fuzzy logic
quantifies vagueness as a smooth gradient between truth and falsehood."

I must admit, ChatGPT's knack for juxtaposing the lofty with the practical
was a pleasant surprise—perhaps an unintended nod to my eclectic career
path!
