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?
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 ( ꩜ . ꩜ ;).
Furthermore, in Tractatus (though he kind of discredited this book later in life), Wittgenstein argues
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)
Maybe you’re confusing him with someone else? :D
