After all we speak of people 'taking refuge' in vagueness -the more precise you are, in general the more likely you are to be wrong, whereas you stand a good chance of not being wrong if you make it vague enough.
J. L. AustinThe 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.
J. L. AustinThere is no one kind of thing that we 'perceive' but many different kinds, the number being reducible if at all by scientific investigation and not by philosophy: pens are in many ways though not in all ways unlike rainbows, which are in many ways though not in all ways unlike after-images, which in turn are in many ways but not in all ways unlike pictures on the cinema-screen--and so on.
