The stone and the soul represent different stages of progression, not different substances. If a charcoal can be transformed into a diamond, why may not nature, with the resources of infinity at her command, refine a stone into a soul? Let us not marvel at this; it is not less thinkable than the proposition of two independent sources of life, the one physical, the other rational. If "life is born of life," where did the first life come from? Let us have an answer to that question. And if, as the professor says, "reason is born of reason," how did the first reason come? Is it not very much simpler to think in monistic terms, than to separate life from reason, and mind from matter, as Prof. Adler does in the words quoted above? Why cannot mind be a state of matter? What objection is there to thinking that matter, refined, elevated, ripened, cultured, becomes both sentient and rational? If matter can feel, can see, can hear, can it not also think? Does not the horse see, hear and think? There is no lowering of the dignity of man to say that he tastes with his palate, sees with his eyes, hears with his ears, and thinks with the gray matter in his brain. Remove his optic nerve and he becomes blind, destroy the ganglia in his brain, and he becomes mindless. Gold is as much matter as the dust, but it is very much more precious; so is mind infinitely more precious than the matter which can only feel, see, taste or hear. "If the anthropoid ape does not possess reason as we possess it, it cannot be said that on our rational side we are his progeny," says Dr. Adler: But, suppose we were to say that if our remote African or Australian savage ancestors did not possess reason as we possess it, "it cannot be said that on our rational side we are their progeny," The child in the cradle does not possess reason "as we do," any more than does the anthropoid ape, but the beginnings of reason are in both. Let the worm climb and he will overtake man. This is a most hopeful, a most beautiful gospel. Its spirit is not one of isolation and exclusiveness from the rest of nature, but one of fellowship and sympathy. We are all--plants, trees, birds, bugs, animals--all members of one family, children at various ages and stages of growth of the same great mother,--Nature. We quote again: "When I ask him (Metchnikoff) whence do I come, he points to the simian stage which we have left behind; but I would look beyond that stage to some ultimate fount of being, to which all that is highest in me and in the world around me can be traced, a source of things equal to the best that I can conceive."
