We are blind. We have no direct contact with the world but we have words, a white stick that we hold one end of. Wittgenstein said that Reality and Language shared a logical form so that nonsense was impossible, just as it was impossible to draw a square circle. If we master words, extending and refining their use, then we master thought.
Language can only imitate thought just as a computer can only simulate weather or intelligence.
Its conclusions and forecasts may be erroneous. There's nothing special about it, but in the hands of a master there are wonders to behold. Words are incantations, summoning up spirits. Words cannot hurt anyone. They have their own momentum, depending more on their mass that their design.
