[CG] Sign Relational Manifolds

Cf: Sign Relational Manifolds • 1 http://inquiryintoinquiry.com/2022/10/31/sign-relational-manifolds-1-2/ All, Riemann's concept of a manifold, especially as later developed, bears a close relationship to Peirce's concept of a sign relation. I will have to wait for my present train of thought to stop at a station before I can hop another but several recent discussions of geometry have brought this subject back to mind and I thought it might serve to drop off a few mail bags of related letters in anticipation of the next pass through this junction. Here are links to a set of excerpts from Murray G. Murphey (1961), “The Development of Peirce's Philosophy”, discussing Peirce's reception of Riemann's philosophy of geometry.
