"Perhaps less true if more beautiful"

Strawson (vide my "Robbing Paul to pay Peter") was unconvinced by most of what Grice wrote. But in "If and -->" he grants: "Hey: Grice's theory may be wrong; still, I would go as far as to grant that it's more beautiful than mine."

Strawson was arguing for the case that

inferrability

is

CONVENTIONALLY implicated by

'-->'

Whereas for Grice it's merely

CONVERSATIONALLY implicated.

Vide Grandy's longish reflections on this in "Legacy of Grice" and vide Bergmann for why he thought these were just some old English futilitarians always ready to waste _his_ time!
