"With every development of speech it became possible to intensify and develop the tradition of tabus and restraints and ceremonies. There is not a savage or barbaric race today that is not held in a net of such tradition. And with the coming of the primitive herdsman there would be a considerable broadening out of all this sort of practice. Things hitherto unheeded would be found of importance in human affairs. Neolithic man was nomadic in a different spirit from the mere daylight drift after food of the primordial hunter. He was a herdsman upon whose mind a sense of direction and the lie of the land had been forced. He watched his flock by night as well as by day. The sun by day and presently the stars by night helped to guide his migrations; he began to find after many ages that the stars are steadier guides than the sun. He would begin to note particular stars and star groups, and to distinguish any individual thing was, for primitive man, to believe it individualized and personal. He would begin to think of the chief stars as persons, very shining and dignified and trustworthy persons looking at him like bright eyes in the night. His primitive tillage strengthened his sense of the seasons. Particular stars ruled his heavens when seedtime was due. Up to a certain point, a mountain peak or what not, a bright star moved, night after night. It stopped there, and then night after night receded. Surely this was a sign, a silent, marvellous warning to the wise."
