Happy birthday, Philosophy Grandpa:
Below is a map of authors in the pragmatist tradition, with a lot of major authors, scientists and activists. The intent here was initially to create something that my student might use as a resource to think about how some big debates unfolded. Where one person contributed favorably to another’s work, a green line connects them. Where one author tended to clash with another, a red line connects them. The connections there are about the predominance of support/agreement or disagreement between the authors. If we were being totally honest, every author should be connected to every other by a variegated braid with more colors than your monitor would support, of course. This simply suggests predominant patterns on stuff for which we would remember their work.
This is a work in progress, as I am sure anyone who sees it can imagine. It might evolve into something else down the line, or it might not. To the degree that it helps others teach this material, feel free to use it.
