The trouble is that the expression 'material thing' is functioning already, from the very beginning, simply as a foil for 'sense-datum'; it is not here given, and is never given, any other role to play, and apart from this consideration it would surely never have occurred to anybody to try to represent as some single kind of things the things which the ordinary man says that he 'perceives.

Ordinary language embodies the metaphysics of the Stone Age.

The beginning of sense, not to say wisdom, is to realize that 'doing an action,' as used in philosophy, is a highly abstract expression--it is a stand-in used in the place of any (or almost any?) verb with a personal subject, in the same sort of way that 'thing' is a stand-in for anynoun substantive, and 'quality' a stand-in for the adjective.

I feel ruefully sure, also, that one must be at least one sort of fool to rush in over ground so well trodden by the angels.

It should be quite clear, then, that there are no criteria to be laid down in general for distinguishing the real from the not real.

Is it true or false that Belfast is north of London? That the galaxy is the shape of a fried egg? That Beethoven was a drunkard? That Wellington won the battle of Waterloo? There are various degrees and dimensions of success in making statements: the statements fit the facts always more or less loosely, in different ways on different occasions for different intents and purposes.

I begin, then, with some remarks about 'the meaning of a word.' I think many persons now see all or part of what I shall say: but not all do, and there is a tendency to forget, or to get it slightly wrong. In so far as I am merely flogging the converted, I apologize to them.
