DA: sorry Jon they seem to stumble at the first post:

DA, quoting JA:
JA: A simple example of a differential logical calculus
    is furnished by a differential propositional calculus.
    This augments ordinary propositional calculus in the
    same way that the differential calculus of Leibniz
    and Newton augments the analytic geometry of Descartes.

JA: That's rubbish, no?

No, but do you have a specific criticism or question?

Jon
