That which has not happened, could not. The present is the necessary product of all the past, the necessary cause of all the future.
In the infinite chain there is, and there can be, no broken, no missing link. The form and motion of every star, the climate of every world, all forms of vegetable and animal life, all instinct, intelligence and conscience, all assertions and denials, all vices and virtues, all thoughts and dreams, all hopes and fears, are necessities. Not one of the countless things and relations in the universe could have been different.
VII.
IF matter and force are from eternity, then we can say that man had no intelligent creator—that man was not a special creation.
We now know, if we know anything, that Jehovah, the divine potter, did not mix and mould clay into the forms of men and women, and then breathe the breath of life into these forms.
We now know that our first parents were not foreigners. We know that they were natives of this world, produced here, and that their life did not come from the breath of any god. We now know, if we know anything, that the universe is natural, and that men and women have been naturally produced. We now know our ancestors, our pedigree. We have the family tree.
We have all the links of the chain, twenty-six links inclusive from moner to man.
We did not get our information from inspired books. We have fossil facts and living forms.
From the simplest creatures, from blind sensation, from organism from one vague want, to a single cell with a nucleus, to a hollow ball filled with fluid, to a cup with double walls, to a flat worm, to a something that begins to breathe, to an organism that has a spinal chord, to a link between the invertebrate to the vertebrate, to one that has a cranium—a house for a brain—to one with fins, still onward to one with fore and hinder fins, to the reptile mammalia, to the marsupials, to the lemures, dwellers in trees, to the simiæ, to the pithecanthropi, and lastly, to man.
We know the paths that life has traveled. We know the footsteps of advance. They have been traced. The last link has been found. For this we are indebted, more than to all others, to the greatest of biologists, Ernst Haeckel.
