[CG] Re: Sign Relational Manifolds

Cf: Sign Relational Manifolds • 3 http://inquiryintoinquiry.com/2022/11/03/sign-relational-manifolds-3-2/ All, I'm not sure when it was I first noticed the relationship between manifolds and semiotics but I distinctly recall the passage in Serge Lang's “Differential and Riemannian Manifolds” which brought the triadic character of tangent vectors into high relief. I copied out a set of excerpts highlighting the point and shared it with the Inquiry, Ontology, and Peirce lists.
