Sentences are not as such either true or false. - John Langshaw Austin

But surely, speaking carefully, we do not sense "red" and "blue" any more than "resemblance" (or "qualities" any more than "relations"): we sense something of which we might say, if we wished to talk about it, that "this is red."

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.

There are more ways of killing a cat than drowning it in butter; but this is the sort of thing (as the proverb indicates) we overlook: there are more ways of outraging speech than contradiction merely.
