II.  Science detached from theology.

Change of the point of view in the science of man. — It is detached from theology and is united with the natural sciences.

Let us suppose a mind thoroughly imbued with these new truths, to be placed on the orbit of Saturn, and let him observe[10].  Amidst this vast and overwhelming space and in these boundless solar archipelagoes, how small is our own sphere, and the earth, what a grain of sand!  What multitudes of worlds beyond our own, and, if life exists in them, what combinations are possible other than those of which we are the result!  What is life, what is organic substance in the monstrous universe but an indifferent mass, a passing accident, the corruption of a few epidermic particles?  And if this be life, what is that humanity which is so small a fragment of it? — Such is Man in nature, an atom, and an ephemeral particle; let this not be lost sight of in our theories concerning his origin, his importance, and his destiny.

“A mite that would consider itself as the center of all things would be grotesque, and therefore it is essential that an insect almost infinitely small should not show conceit almost infinitely great."[11] —

How slow has been the evolution of the globe itself!  What myriads of ages between the first cooling of its mass and the beginnings of life![12] Of what consequence is the turmoil of our ant-hill compared to the geological tragedy in which we have born no part, the strife between fire and water, the thickening of the earth’s crust, formation of the universal sea, the construction and separation of continents!  Previous to our historical record what a long history of vegetable and animal existence!  What a succession of flora and fauna!  What generations of marine organisms in forming the strata of sediment!  What generations of plans in forming the deposits of coal!  What transformations of climate to drive the pachydermata away from the pole! — And now comes Man, the latest of all, he is like the uppermost bud on the top of a tall ancient tree, flourishing there for a while, but, like the tree, destined to perish after a few seasons, when the increasing and foretold congelation allowing the tree to live shall force the tree to die.  He is not alone on the branch; beneath him, around him, on a level with him, other buds shoot forth, born of the same sap; but he must not forget, if he would comprehend his own being, that, along with himself, other lives exist in his vicinity, graduated up to him and issuing from the same trunk.  If he is unique he is not isolated, being an animal among other animals;[13] in him and with them, substance, organization and birth, the formation and renewal of the functions, senses and appetites, are similar, while his superior intelligence, like their rudimentary intelligence, has for an indispensable organ a nervous matter whose structure is the same with him as with
