i have had similiar thoughts. Like because we think in language we think as we would speak, so essentially we would think slower, and think of words and not an idea or something as a whole. This is partly why i think when we are asleep and unconcouis we can think much faster because we arent thinking in language, or something like that, i made it sound much better while i was high and i wrote it down in my philosphy notebook for when i'm high but i left that in my car and i'm posting w/o it. But you all should get the jist of what i'm getting at.
