You think it is all a dream, all a fancy! But to say that, you must be making the preposterous claim that evolution is over, and that you are the highest products which Nature is able to bring to birth. We are far higher than the savages: should there not be races higher than we are? Surely Nature’s power is not exhausted; surely she, who has gradually builded up the exquisite mechanism of the human retina from the pigment spot in the nervous ring of the medusa, surely she can evolve these eyes further and further, to greater power of sight. It all grows out of the Spirit, and of the Spirit there is no ending. If you see to-day with your eye it is because the Spirit in you willed to see, and by that will built up the organ which made the will effective in the material world; and that same Spirit that evolved you in the past is living in you now, and is your innermost Self; its powers are not exhausted, its inspiration is not over, it is still the architect of the human body, as the divine Spirit is the architect of the universe. Ever to higher and higher forms of matter, ever to loftier and loftier stages of consciousness, everlastingness stretches in front of us, as everlastingness stretches behind us. As we have climbed, so we shall climb; as we have come upwards from the dust, so shall we ascend to the stars; for the Spirit of God within us knows no limitation either in time or space, and the evolution of the future should be a millionfold more splendid than the evolution which has made us what we are.
