I can think in language but my thoughts are certainly not limited to it. If language would be the reason for complex thinking, shouldn't I then be able to express my complex thoughts? If emotions are an act of thinking without the use of language, how could I then translate a feeling into an intellectual reaction without loosing some of the essential details? Could the problem lie in the definition or even the anticipation we might have of language, or that we sometimes confuse communication with verbal exchange? Hope you understand what I am trying to say!
