Who was the philosopher that said miscommunication was the chief cause of all human suffering?

Some people are responding that this was Wittgenstein. Some correction: Wittgenstein held the view that philosophical problems arose from the confusion of language in various ways, e.g. trying to express in language what language cannot logically express or using words outside of the ways we use them in our everyday lives. This, however, is not the same as all human suffering.

But there's hardly a well-known philosopher who made the claim in the OP so Wittgenstein makes sense as the philosopher closest to anything like that claim. To be accurate to Wittgenstein's philosophy, though, it should be made clear that this is not Wittgenstein's claim, if it's anyone's at all.
