Grice defines eschatology (philosophical)

--- Grice wrote:

"Some time ago the idea occurred to me that there might be
two distinguishable disciplines each of which might have some claim to the
title of ... Metaphysics. The first ... I thought of as being categorial in
character ... The second ... I thought of as being supracategorial in character;
it would bring together categorially different subject-items beneath single
classificatory characterisations, and perhaps would also specify principles
which would have to be exemplified by items brought together by this kind of
supracategorial assimilation. I hoped that the second discipline, which I was
tempted to label 'Philosophical Eschatology,' might provide for the detection
of affinities between categorially different realities, thus protecting the
principles associated with particular categories from suspicion of
arbitrariness." (Studies in the Way of Words, -- section 'Explorations in Semantics
and Metaphysics', p. 304).
