Here you have the important transition that took place about 500 B.C. This is the date of the Buddha and of Pythagoras and Confucius and Lao-tzu, if there was a Lao-tzu. This is the awakening of man’s reason. No longer is he informed and governed by the animal powers. No longer is he guided by the analogy of the planted earth, no longer by the courses of the planets—but by reason.
