Strange that the PDF costs £70 (same as hardcover) but the epub costs £20 (same as paperback). I'm considering purchasing the epub, but if somebody has done so I'd be curious if the typography seems degraded, as sometimes happens for graphics-heavy publications.

@Kartik Agaram I have been tracking down diagrammatic notations for sometime and there’s some strange ideas lurking there, like most computational artifacts (lets say logical flow of electricity to point to a relatable example) seems to be tracing logical pictures (think the Boolean lattice walks). There’s some kind of deep sense in which diagrams conduct the world around us, thought articulation is beyond me at the point on exactly how. Needs a sound theory, which is what I think Peirce and Gestalt philosophers attempts to ground with their work. And CT as the emerging process theory that binds geo, alg, logic, and topology, I think it is a good setting where this can be expressed.

@Garth Goldwater I happened to find out recently that Husserl was trained originally as a math major. Also, I went on to trace history of logic during these searches and happened to find a lot of people who affirm Leibnizian thinking that a philosopher should be a mathematician.

@wtaysom Would love to hear your opinion if you read it.
