John S., List: JFS: ... icons as the starting point ... diagrams as lawful constructions from icons ...
I am still getting hung up on this way of putting it. As I understand it, diagrams *are* icons, at least predominantly; but rather than its object's *qualities*, a diagram embodies the significant *relations *among its parts. JFS: All perception and imagination is by individuals. But by collaboration, we can share our imaginations, build on them, refine them, correct them. This is where the concreteness of diagrams comes in handy; they can be transferred from one person's imagination to another's by means of words, equations, drawings, and other physical manifestations. JFS: I don't think that he used the term 'internal' and 'external'. What I was really asking about is the notion that "every kind of sign begins with an image (icon), and every sign constructed from other signs is a diagram." Does this come from Peirce, or is it your own insight? In "Some Consequences of Four Incapacities" (1868), he flatly *denied *that we have *any *images in perception or imagination, although in that work he was referring to "absolutely determinate representations." I am also not sure that it is correct to characterize *every *sign constructed from other signs as a diagram in Peirce's technical sense. Damasio: The distinctive feature of brains such as the one we own is their uncanny ability to create maps... But when brains make maps, they are also creating images, the main currency of our minds. Ultimately consciousness allows us to experience maps as images, to manipulate those images, and to apply reasoning to them. Given Peirce's early denial that we think in images, and his later careful distinction of images from diagrams, I doubt that he would have endorsed these comments as written, at least without knowing their original context. A map or other mental model is an icon, but it is a diagram *rather than* an image. I suppose that if all Damasio means by "image" here is what Peirce meant by "icon," then perhaps they were on the same page after all.
