In order to grasp the idea of the Universality of Mind, let us go back to the elementary forms of Things, and, step by step, see how Mentation manifests itself in every point on the scale from mineral to man--using bodies ranging from the hardest rock to that finest form of known Substance--the Brain of Man. As Mind advances in the scale of evolution it creates its own working instrument--the body (including the brain) and shapes, and moulds it to admit of the fullest possible expression of Mentation possible at that stage. Mind is the moulder--body (and brain) that which is moulded. And Inclination, Desire, and Will, are the motive powers leading to gradual Unfoldment, the impelling cause being the craving for Satisfaction. We shall make our journey backward--and ignoring Beings higher in the scale, we shall start with Man. Leaving out of the consideration, for the moment, the fact of the existence of the "Ego," or "Spirit" of Man, which is higher than Body or Mind--and considering "the Mind of Man," rather than the Man himself--we have our starting point on the downward journey of investigation. We need not devote much attention to the consideration of the Mind of Man, at this stage, although we shall have much to do with it, later on. But we may undertake a brief consideration of the descending degrees of Mentation as manifested by Man, as we pass down the scale in the human family, considering in turn, the Newtons, Shakespeares, Emersons, Edisons, and their brothers in intellect, in the field of mathematics, literature, music, art, invention, science, statesmanship, business, skilled workmanship, etc., respectively. From these high levels we pass down, gradually, through the strata of men of but a slightly lower degree of intellect--down through the strata of the "average man"--down through the strata of the ignorant man--down through the strata of the lowest type of our own race and time--down through the strata of the barbarian, then on to the savage, then on to the Digger Indian, the Bushman. What a difference from highest to lowest--a being from another world would doubt that they were all of the same family.
