they are not a sudden creation; they are an evolution; they were potential in the earth before they arose out of it.  The earth ripened, her crust mellowed, and thickened, her airs softened and cleared, her waters were purified, and in due time her finer fruits were evolved, and, last of all, man arose.  It was all one process.  There was no miracle, no first day of creation; all were days of creation.  Brooded by the sun, the earth hatched her offspring; the promise and the potency of all terrestrial life was in the earth herself; her womb was fertile from the first.  All that we call the spiritual, the divine, the celestial, were hers, because man is hers.  Our religions and our philosophies and our literatures are hers; man is a part of the whole system of things; he is not an alien, nor an accident, nor an interloper; he is here as the rains, the dews, the flowers, the rocks, the soil, the trees, are here.  He appeared when the time was ripe, and he will disappear when the time is over-ripe.  He is of the same stuff as the ground he walks upon; there is no better stuff in the heavens above him, nor in the depths below him, than sticks to his own ribs.  The celestial and the terrestrial forces unite and work together in him, as in all other creatures.  We cannot magnify man without magnifying the universe of which he is a part; and we cannot belittle it without belittling him.

Now we can turn all this about and look upon it as mankind looked upon it in the prescientific ages, and as so many persons still look upon it, and think of it all as the work of external and higher powers.  We can think of the earth as the footstool of some god, or the sport of some demon; we can people the earth and the air with innumerable spirits, high and low; we can think of life as something apart from matter.  But science will not, cannot follow us; it cannot discredit the world it has disclosed—­I had almost said, the world it has created.  Science has made us at home in the universe.  It has visited the farthest stars with its telescope and spectroscope, and finds we are all akin.  It has sounded the depths of matter with its analysis, and it finds nothing alien to our own bodies.  It sees motion everywhere, motion within motion, transformation, metamorphosis everywhere, energy everywhere, currents and counter-currents everywhere, ceaseless change everywhere; it finds nothing in the heavens more spiritual, more mysterious, more celestial, more godlike, than it finds upon this earth.  This does not imply that evolution may not have progressed farther upon other worlds, and given rise to a higher order of intelligences than here; it only implies that creation is one, and that the same forces, the same elements and possibilities, exist everywhere.
