Meaning, Purpose, Intention

The Use-Purpose relation is essentially one of Mechanical Causality, i. e. to use U in order to bring about P presupposes that U causes P.  Thus, if, as Wittgenstein posits, Meaning is identical to Purpose, the Signal-Response relation is a mechanical one.  But, as has been previously argued here, a response to an utterance is fundamentally voluntary, and, hence, does not reduce to a mechanical effect of it.  Instead, a Pragmatist concept of Meaning that is more accurate than Purpose is Intention, the fulfillment of which cannot be taken for granted, and which conforms to how it is conceived in ordinary conversation, e. g. 'What do you mean by that?' is commonly regarded as synonymous with 'What do you intend by that?.
