The conception of force by itself is but a very late idea. As one by one the phenomena of nature attract man's observation he personifies them. It will be noticed that unless a force intrudes itself on him he does not personify it. What people ever personified gravity? And why not? Surely gravity is evident enough. Every time a savage dropped a stone on his toes he would recognise gravity. But no. That a stone falls to the ground because a force draws it is an idea very late to enter man's brain. It seems to him, as he would say, the nature of a stone to fall. And then gravity acts always in the same way. It is not intermittent--like lightning, for instance. Therefore he never conceives of gravity as a force at all. When men had come to perceive that it was a force, they had passed the personifying stage. But the savage personified each force as he perceived it. First the sun and storm, till at last he came to himself and began to study his own life. He had good and bad luck; that was Fortune. Evil deeds are done, and good; he is beginning to classify and generalise; there are gods of Good and Evil. He has come to Ormuz and Ahriman little by little; as his power of generalising progresses, he drops the smaller gods. They disappear, they are but attributes of greater gods. And as he grows in mental grasp and makes himself the centre of his world, so does the God of Man become the God of Nature too. The greater absorbs the lesser. The God who cared for man, the God of his past, of his present, of his future, is become the great God. He rules all the gods until he alone is God. So it seemed to the man that God arose, never out of reason, always out of instinct. There was no difference. It is all the same story. There is innate in all men a tendency to personify the forces they cannot understand. Because they want an explanation, and personality is the only one that offers at first. To attribute effects to persons is aboriginal science. To attribute them to natural laws is later science. Each is the answer to the same question. Men personify forces in different ways according to their mental and emotional stature, to their capacity for generalising. They express their ideas in different ways according to their race and their country. The Hindu began with a god in each force, to represent each idea, and so the lower people still remain, afraid of many gods. But those of mental stature gradually generalised, till at last they came to one God, Brahm, and the lesser gods as emanating from him. This was a hierarchy; and then finally the greatest thinkers came to one God only, and the idea that the lesser gods are but representatives of His manifold nature. You can see all the stages before you now. It is simply a question of brain power, and the sequence remains the same. First the lesser, then the greater. It is never the other way on.
