From the Internet Encyclopedia of Philosophy [1]:
“Knowing the meaning of a word can involve knowing many things: to what objects the word refers (if any), whether it is slang or not, what part of speech it is, whether it carries overtones, and if so what kind they are, and so on. To know all this, or to know enough to get by, is to know the use. And generally knowing the use means knowing the meaning. Philosophical questions about consciousness, for example, then, should be responded to by looking at the various uses we make of the word “consciousness.” Scientific investigations into the brain are not directly relevant to this inquiry (although they might be indirectly relevant if scientific discoveries led us to change our use of such words). The meaning of any word is a matter of what we do with our language, not something hidden inside anyone’s mind or brain. This is not an attack on neuroscience. It is merely distinguishing philosophy (which is properly concerned with linguistic or conceptual analysis) from science (which is concerned with discovering facts).”
