Robert M. Pirsig quotes - page 4
In this allegory the seeker, trying to reach the One, is drawn by two horses, one white and noble and temperate, and the other surly, stubborn, passionate and black. The one is forever aiding him in his upward journey to the portals of heaven, the other is forever confounding him. The Chairman has not stated it yet, but he is at the point at which he must now announce that the white horse is temperate reason, the black horse is dark passion, emotion. He is at the point at which these must be described, but the false note suddenly becomes a chorus.
