In countries where drouth, barrenness, and consequent famine were occasional, as in India, it would be an inevitable result that they would represent the varying moods of a powerful will, and in such regions we naturally find the most extensive appliances for propitiation. The preponderant number of fat years would tell powerfully on the popular imagination in favour of priestly intercession, and the advantage of sacrifices to the great Hunger-demon who sometimes consumed the seeds of the earth. But in countries where barrenness was an ever-present, visible, unvarying fact, the Demon of the Desert would represent Necessity, a power not to be coaxed or changed. People dwelling in distant lands might invent theoretical myths to account for the desert. It might be an accident resulting from the Sun-god having given up his chariot one day to an inexperienced driver who came too close to the earth. But to those who lived beside the desert it could only seem an infernal realm, quite irrecoverable. The ancient civilisation of Egypt, so full of grandeur, might, in good part, have been due to the lesson taught them by the desert, that they could not change the conditions around them by any entreaties, but must make the best of what was left. If such, indeed, was the force that built the ancient civilisation whose monuments remain so magnificent in their ruins, its decay might be equally accounted for when that primitive faith passed into a theological phase. For as Necessity is the mother of invention, Fate is fatal to the same. Belief in facts, and laws fixed in the organic nature of things, stimulates man to study them and constitute his life with reference to them; but belief that things are fixed by the arbitrary decree of an individual power is the final sentence of enterprise. Fate might thus steadily bring to ruin the grandest achievements of Necessity.
