- "gives a name to a certain class of colors"? That is a thoroughly
- theory-laden assertion.
- My 2-year-old uses "green" as a term of
- approbation (at least, that's the closest I can figure it). He does not
- have the technique of using color words to refer to what we adult language
- users think of as colors. So it is not "looks" he is comparing. But he *is*
- using linguistic utterances to express his comparison of observations.
- Only when he gains some sophistication will adults be able to straighten
- out his conceptual scheme by explaining some theoretical considerations
- about color-terms and what kind of observations are relevant to them.
- He may not yet have an explicit theory (or even an explicit concept) but
- in order to interact with him you have to have theories and concepts, and
- you have to be able to transmit them to him. His (socially correct)
- observations *will* be theory-laden.
