I was taking a Dance History class the other day and my professor made a comment stating: Philosophers believe that if one does not possess a language to express their thoughts, they have none. Is this true? If so, how does one express the phenomenons of people with disabilities (such as being deaf) or even one of the greatest minds in the world: Helen Keller? If one does not have a language to verbally express emotion, why are other non-verbal forms of communication (especially dance) not justified in the eyes of the philosopher?
