When is the statement "I brought you the chairs you wanted" *true*? It depends on what they were wanted *for*.
Lakoff and Johnson, p. 164:
> Suppose you say to me, "We're having a discussion group over tonight, and I need four more chairs. Can you bring them?" I say "Sure," and show up with a hardback chair, a rocking chair, a beanbag chair, and a hassock. Leaving them in your living room, I report to you in the kitchen, "I brought the four chairs you wanted." In this situation, my statement is true, since the four objects I've brought will serve the purpose of chairs for an informal discussion group. Had you instead asked me to bring four chairs for a formal dinner and I show up with the same four objects and make the same statement, you will not be appropriately grateful and will find the statement misleading or false, since the hassock, the beanbag chair, and rocker are not practical as "chairs" at a formal dinner.
Put differently, the host might say the statement was *technically* true but not helpful. Pragmatism the Philosophy would say we might as well label that "false".
