KK: To me, differences are the result of drawing distinctions.
They don't exist unless you actively draw them. So, the
act of drawing distinctions is more fundamental than the
differences thereby created.
I often return to that line from Ashby. This time I thought it made an apt segue from the scene of propositional
calculus, where universes of discourse are ruled by collections of distinctive features, to the differential extension
of propositional calculus, which enables us to describe trajectories within and transformations between our logical
universes.
So I agree with Klaus Krippendorff about "which came first", the distinctions drawn or the states distinguished in space
or time. The primitive character of distinctions is especially salient in this setting since our formalism for
propositional calculus is built on the forms of distinction pioneered by C.S. Peirce and augmented by George Spencer Brown.
