Something I was thinking about today.  While we think with language, thought is not dependent on language.  Thought precedes the development of language.  If that were not so, language would never develop.  Learning a language is the process of learning established signs and symbols that correspond to, and help us express our pre-existing thoughts.  If we had no thoughts, there could be no correspondence, and we would be incapable of using the signs and symbols of language to convey meaning.

So what would it be like to think without the use of language?  I don’t know.  Infants must do it, but none of us remember what it was like to be an infant, so I imagine this is an unanswerable question.  It’s interesting nonetheless.
