Diagogic, Not Epagogic

In his brilliant, "Prejudices and predilections of H. P. Grice" a section of "The Life and Times of H. P. Grice", by H. P. Grice, H. P. Grice writes (words to that perlocutionary effect):

Diagogise, never epagogise

The reference is _obviously_ to Aristotle.

For Aristotle, and for Kant, and for Kantotle, and for Ariskant, and for Grice, there are

TWO and TWO ONLY

ways of putting forward a claim:

(1) The Good, "Positive" Way
which Grice calls "diagogic"

(2) The Bad, "Negative" Way
which Grice dubs "epagogic"

--- The asymmetry of this type of arguing should be relevant to anyone familiar with Popper, so let's wait for her ("anyone familiar with Popper") to plunge in!
