Chuang Tzu (370BC-287BC)

After a little time, Hsü Wû-kwei said, "Let me tell your lordship something:- I look at dogs and judge of them by their appearance. One of the lowest quality seizes his food, satiates himself, and stops;- he has the attributes of a fox. One of a medium quality seems to be looking at the sun. One of the highest quality seems to have forgotten the one thing,- himself. But I judge still better of horses than I do of dogs. When I do so, I find that one goes straight forward, as if following a line; that another turns off, so as to describe a hook; that a third describes a square as if following the measure so called; and that a fourth describes a circle as exactly as a compass would make it. These are all horses of a state; but they are not equal to a horse of the kingdom. His qualities are complete. Now he looks anxious; now to be losing the way; now to be forgetting himself. Such a horse prances along, or rushes on, spurning the dust and not knowing where he is." The marquis was greatly pleased and laughed.
