Yes, but philosophy has had a somewhat checkered history with regard to language, culminating of course in positivism's misguided efforts at creating a perfectly transparent language of logic. This is what Wittgenstein set out to do with the
Tractatus, and by the end of it realized he'd basically argued the opposite. Philosophy usually tends to appropriate and utilize language in a manner different than literature per se, yet it often appeals to literary language in order to make its point. If we permit philosophy this resource - which, as you suggest, is necessary - then we have to be cautious where philosophy appears to treat its claims (or theorems, axioms, whatever) as though they're obvious, or entirely transparent - for its usually in moments like these that language plays tricks on us.
The humanities are all about the practice of reading, reading as a critical activity. It isn't purely about interpretation, but about how interpretation contributes to a discourse. Philosophy, simply by the nature of the discourse, has to assume a somewhat untroubled relationship to the words it uses. Literary studies can have some insight here.
EDIT:
Edit: Good blog post, a lot to chew on there. I do want to object to the move you make early on in trying to define and frame intelligence. It is true, at least broadly and up to the current era, that intelligence is discoverable/assessable via behavioral expression only. But it does not logically follow then that intelligence is merely behavior. There's a longstanding tension in psychology between cognitivists and behaviorists, but even behaviorists don't jump that far in justifying their orientation (at least not to my knowledge).
Thanks. I take your point about behaviorism vs. cognitivism, and intelligence not being reducible to behavior. I may emphasize the point too strongly in the post, because I don't think I want to say that it "logically follows" that behavior is intelligence (can't recall if I used these words or not). Rather, because behavior is all that we can verify, it makes sense to associate this with intelligence, and resist reifying intelligence into some internal substance.
It is illogical to assume that behavior equals intelligence, but it's also illogical to assume that performance on an IQ exam reflects some interior core of intelligence. And until we can prove the connection between behavior and internal substance, then I think it makes sense to pursue AI studies (and other fields involving intelligence) in terms of where intelligence does manifest - i.e. in behavior.
