He also said that nothing had to be true, but everything had to sound true. - Isaac Asimov

There is an old fable," said Hardin, "as old perhaps as humanity, for the oldest records containing it are merely copies of other records still older, that might interest you. It runs as follows: "A horse having a wolf as a powerful and dangerous enemy lived in constant fear of his life. Being driven to desperation, it occurred to him to seek a strong ally. Whereupon he approached a man, and offered an alliance, pointing out that the wolf was likewise an enemy of the man. The man accepted the partnership at once and offered to kill the wolf immediately, if his new partner would only co-operate by placing his greater speed at the man's disposal. The horse was willing, and allowed the man to place bridle and saddle upon him. The man mounted, hunted down the wolf, and killed him. "The horse, joyful and relieved, thanked the man, and said: 'Now that our enemy is dead, remove your bridle and saddle and restore my freedom.' "Whereupon the man laughed loudly and replied, 'Never!' and applied the spurs with a will.

It's always easy to explain the unknown by postulating a superhuman and arbitrary will.

The general pattern of water circulation, particularly in the northern hemisphere's Atlantic Ocean, is fairly well understood. As cold water sinks to the bottom of the sea around the Arctic Ocean, it travels slowly southward along the sea-bottom toward the Equator. Once it reaches the equatorial tropics it is warmed and accordingly rises to the surface, after which it slowly moves northward, in the form of the ocean surface currents mariners have long learned to map, making a complete circuit as the water returns toward the Pole.
