ABSTRACT
The chapter defines intelligence in terms of mastery of certain distinguishable developed traditions of inquiry and bodies of thought. The view about the relationship between language and thought is in author's view of straightforward common sense. But it needs to be spelt out and asserted, because for some years three popular heresies that involve failure to see it have continued going the rounds. First, that there are a number of different types of language to be found in a community and that all are as good as each other; second, that writing is merely one of many modes of expression, comparable to, say, music, painting, or movement; and third, that language and thought are not crucially related, and that consequently intelligence can easily be divorced from being verbally articulate. Thus the conclusion seems to develop the intelligence of individuals in practical terms, in a concern to develop the capacity to use language well, in the sense of rationally.
