Does intelligence have anything to do with speech and articulation problems?
Can your intelligence effect your speech and articulation? I found this interesting post on Reddit earlier about this topic. I really feel this post as someone with speech disorders and a intellectual disability I've wondered this before. Is it true tho?
I think the study of Ludwig Wittgenstein is all about language being at the center of intelligence, no? I think it even argues that there is no real intelligence without language.
Ironically, Wittgenstein's Philosophical Investigations touches on how thinkers often confuse themselves by slightly shifting the meanings of others' words (like a game of telephone!) -- and, you may have done that here, since he's never framed language in the way you mentioned ( ꩜ . ꩜ ;).
Philosophy is a battle against the bewitchment of our intelligence by means of language. r/philosophy discussion
Furthermore, in Tractatus (though he kind of discredited this book later in life), Wittgenstein argues
What can be shown cannot be said
as a weakness of propositional language (vs. e.g. pictorial language) -- then, this is yet further against "language being at the center in intelligence". (Stanford Plato discussion)
