You are more than entitled not to know what the word 'performative' means. It is a new word and an ugly word, and perhaps it doesnot mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.
J. L. AustinAfter 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. AustinIt should be quite clear, then, that there are no criteria to be laid down in general for distinguishing the real from the not real.
J. L. AustinNext, 'real' is what we may call a trouser-word. It is usually thought, and I dare say usually rightly thought, that what one might call the affirmative use of a term is basic--that, to understand 'x,' we need to know what it is to be x, or to be an x, and that knowing this apprises us of what it is not to be x, not to be an x. But with 'real' (as we briefly noted earlier) it is the negative use that wears the trousers.
