RATIONALLY MOTIVATED ACTION:
A REPLY TO MICHAEL PERRY
ROBERT P. GEORGE*
I wish to thank Michael Perry for his gracious reply to my
critique of his account of moral knowledge. Professor Perry
generously devotes several paragraphs of A Brief Comment to
my criticisms.I I wish to reciprocate by examining his four main
points against my argument and by explaining why I remain
unpersuaded.
First, Professor Perry claims that I have ignored or misun-
derstood his basic, Wittgensteinian critique of the Adler-Finnis
reliance on 'self-evidence.' 2 But Perry offered no such critique
for me to ignore or misunderstand. In Morality, Politics, and
Law, Perry only quoted a passage from Wittgenstein's On Cer-
tainty that seems to deny the possibility of self-evident practical
principles. Perry then declared, without argument, that
Wittgenstein's claim is the better view.'3 He quotes the pas-
sage again in A Brief Comment:
Giving grounds... comes to an end;-but the end is not cer-
tain propositions' striking us immediately as true, i.e. it is not a
kind of seeing on our part; it is our acting, which lies at the
bottom of the language-game.4
Whatever may be said on behalf of Wittgenstein's claim, its
bare statement cannot reasonably be interpreted as a critique of
competing views, whether mine, Adler's, Finnis's, or anyone
else's. Moreover, even if the claim turned out to be true, its
truth is not self-evident. In any event, Perry is not in a position
to claim that it is self-evident. He makes no effort, either in
Morality, Politics, and Law or in A Brief Comment to defend the
