"The work was important, but for Pitts it was unsettling because it punctured his view of the brain as a hierarchy of logical propositions."
That's interesting to me, because the visual system (in the standard account anyway) is at least a bit like a hierarchy of propositions; contrast detectors build up into edge detectors, edge detectors build up into shape detectors, and so on. That paper even identifies fly detectors, which more or less signal the proposition "there is a fly in this part of the visual field".
I wonder what kind of results Pitts had in mind, if this was insufficiently propositional?
