"This is all that “ordinary” in the phrase “ordinary language..." — Stanley Cavell quote meaning

This is all that “ordinary” in the phrase “ordinary language philosophy” means, or ought to mean. It does not refer to particular words of wide use, nor to particular sorts of men. It reminds us that whatever words are said and meant are said and meant by particular men, and that to understand what they (the words) mean you must understand what they (whoever is using them) means, and that sometimes men, do not see what they mean, that usually they cannot say what they mean, that for various reasons they may not know what they mean, and that when they are forced to recognize this they feel they do not, and perhaps cannot, mean anything, and they are struck dumb.
