Hence, with a certain oversimplification, we can say that meaning was traditionally usually conceived of as a chunk of a mind-stuff glued to a word and animating it. This mentalist notion of meaning, tallying as it does with the common sense view of language, kept its intellectual appeal well into the twentieth century and, in some philosophical circles, it is still taken as almost self-evident.
But suppose the word 'beetle' had a use in these people's language?
If people attach something to a word within their minds, then this is a fact of their individual psychologies, not capable of establishing the different fact that the word actually means something within their language.
In order for it to mean something, it is not enough that each of them individually makes the association, he/she must also know that the others do the same, that he/she can use the word to intelligibly express its meaning in various public circumstances etc. Language is essentially public; and as such it cannot rest on private associations.
When we start to use a suitable piece of stone to drive nails, it undoubtedly gains, thereby, in significance; but it seems that the difference between a meaningful word and a meaningless sound or inscription is something worlds apart from the difference between a stone used for driving nails and one that is of no use. When we say that the former stone, in contrast to the latter one, means something to us, we would seem to be employing means in a sense which is totally different from the sense in which we are using it when we say that a word means thus and so. Is not saying that a word has a meaning in the sense that it is useful for some purpose something quite different from saying that the word has meaning in the sense of having a 'semantic value'?
What miraculous kind of use could make a word acquire a genuine meaning, such as those we experience when we talk?
The reason for this shift is that while we persist in seeing the quest for meanings as necessarily underlying and prior to any explanation of our language games, we are kept in the grip of a certain view of the nature of language – the view that a word comes to be meaningful only by being associated, within our mind, with some kind of entity.
Quine therefore holds that to discover what meaning is, we must study how we acquire meanings, in particular which aspects of human behavior an adept of language must observe to learn what a word means.
We want to know what the meaning of a word is because we want to know how the word manages to be so amenable for us.
In fact, if we can pinpoint this out without getting hold of any entity which we could call the meaning of the word, we would not seem to miss anything.
