 Worries about compositionality aside, most of the problems associated with meaning holism are tied to the way in which it seems to make meaning idiosyncratic and  unstable.[15]  If what one meant by a term were individuated in terms of, say, all of the beliefs or inferences that one was disposed to make with it, then two people (or one person at two times) would only mean the same thing by any of their terms if all of their beliefs or inferential dispositions were identical. In effect, meaning holism threatens to erase the distinction between change/differences of meaning and change/differences of belief, so that every time I change any one my beliefs, I change the meanings of all of my terms, and any time two people fail to share a single belief, the meaning of all their terms and the content of all of their beliefs must  differ.[16]
