“ The commonly recognized ways of human utterance are gesture and oral speech—the one appealing to the eye, the other to the ear, and each leaving its record probably at different points and in different molecular form in the brain. Hand gesture came in course of time to be the highest type of gesture language, evolving as it did into a highly complex and adaptable type of language, and modern hand writing is simply a form of hand gesture which, by means of ink or lead or chisel, or some other material or instrument, leaves a trail of the hand movement in permanent record. ”
