> We have good research showing we think in language.

Source? From my knowledge, we do not "think in language", but we learn to finetune our thinking to be expressed in the form of words. Unless you consider pictures as language, after all "A picture is worth a thousand words"..

I think what you mean is Language shapes our thinking, but it is not a requirement of it.

That implies that nonverbal people are unable to think, no?

What? What does it have to do with anything that I said? Wow, I think HN has lost its spark.
