Dr. Darwin's theory of evolution and selection has changed our modern mode of studying the inorganic and organic phenomena of nature, and investigating the realities of truth. His theory is not altogether new, having been first proclaimed by Leibnitz, and followed up with regard to history by Giovanni Battista Vico. Oken and Goethe amplified it towards the end of the last, and at the beginning of the present century. Darwin, however, has systematized the theory of evolution, and now the branches of human knowledge can only be advantageously pursued if we trace in all phenomena, whether material or spiritual, a beginning and a gradual development. One fact has prominently been established, that there is order in the eternal change, that this order is engendered by law, and that law and order are the criterions of an all-wise ruling Spirit pervading the Universe. To this positive spirit of law a spirit of negation, an element of rebellion and mischief, of mockery and selfishness, commonly called the Devil, has been opposed from the beginning.

It appeared, till very lately, as though God had created the world only for the purpose of amusing the Devil, and giving him an abundance of work, all directed to destroying the happiness of God's finest creation—man. Treating the Devil from a Darwinian point of view, we may assert that he developed himself from the protoplasm of ignorance, and in the gloomy fog of fear and superstition grew by degrees into a formidable monster, being changed by the overheated imaginations of dogmatists into a reptile, an owl, a raven, a dog, a wolf, a lion, a centaur, a being half monkey, half man, till, finally, he became a polite and refined human being.

Man once having attained a certain state of consciousness, saw sickness, evil, and death around him, and as it was usual to assign to every effect some tangible cause, man developed the abstract notion of evil into a concrete form, which changed with the varying impressions of climate, food, and the state of intellectual progress. To the white man the Devil was black, and to the black man white. Originally, then, the Devil was merely a personification of the apparently destructive forces of nature. Fire was his element. The Indians had their Rakshas and Uragas, the Egyptians their Typhon, and the Persians their Devas. The Israelites may claim the honour of having brought the theory of evil into a coarse and sensual form, and the Christians took up this conception, and developed it with the help of the Gnostics, Plato, and the Fathers dogmatically into an entity.

I shall not enter on a minute inquiry into the origin of this formidable antagonist of common sense and real piety; I intend to take up the three principal phases of the Devil's development, at a period when he already appears to us as a good Christian Devil, and always bearing in mind Mr. Darwin's theory of evolution, I shall endeavour to trace spiritually the changes in the conceptions of evil from the Devil of Luther to that of Milton, and at last to that of Goethe.

The old Jewish Rabbis and theological doctors were undoubtedly the first to trace, genealogically, the pedigree of the Christian Devil in its since general form. If we take the trouble to compare chap. i. v. 27 of Genesis with chap. ii. v. 21, we will find that two distinct creations of man are given. The one is different from the other. In the first instance we have the clear, indisputable statement, "So God created man in his own image:" and to give greater force to this statement the text goes on, "in the image of God created he him; male and female created he them." Both man and woman were then created. Nothing could be plainer. But as though no creation of man had taken place at all, we find, chap. ii. v. 7: "And the Lord formed man of the dust of the ground, and breathed into his nostrils the breath of life." This was evidently a second man, differently created from the first, who is stated to have been made "in the image of God himself." This second creature was entrusted with the nomination and classification of all created things; that is, with the formation of language, and the laying down of the first principles of botany and zoology. After he had performed this arduous task it happened that "for Adam there was not found an help meet for him" (verse 20), and chap. ii. v. 21 tells us, "The Lord God caused a deep sleep to fall upon Adam, and he slept; and He took one of his ribs and closed up the flesh instead thereof;" and verse 22, "And of the rib which the Lord God had taken from man made He a woman, and brought her unto man." Adam then joyfully exclaims (verse 23), "This is now bone of my bones, and flesh of my flesh." This cannot but lead to the conclusion that this woman was an altogether different creature from the first. The contradiction was most ingeniously explained by the learned Jewish Rabbis, who considered the first woman the organic germ from which the special Hebrew-Christian devils were evolved. The Rabbis discovered that the name of the first woman was "Lilith"[1] (the nightly); they knew positively—and who can disprove their assertion?—that she was the most perfect beauty, more beautiful than Eve; she had long waving hair, bright eyes, red lips and cheeks, and a charmingly finished form and complexion; but having been created at the same moment as the first man, and like him, in the image of God, she refused to become man's wife; she objected to being subordinate to the male part of creation—she was, in fact, the first strong-minded woman, claiming the same rights as man, though a woman in body and form. Under these circumstances the existence of the human race was deemed to be an impossibility, and therefore the Lord had to make good his error, and He created Eve as the completing part of man. The first woman left her co-equally created male, and was changed into an enormous, most beautiful, and seducing "She Devil," and her very thoughts brought forth daily a legion of devils—incarnations of pride, vanity, conceit, and unnaturalness. Happily these devils were so constituted that they devoured one another. But in their rage they could take possession of others, and more especially entered little children—boys under three days old, girls under twenty days—and devoured them. This myth, by means of evolution and the law of action and re-action, engendered the further legend about the existence of three special angels who acted as powerful antidotes to these devils, and whose names, "Senoi, Sansenoi, and Sanmangeloph," if written on a piece of parchment suspended round the neck of children afforded certain protection against them.

The origin of the Devil may thus be traced to the first vain contempt for the eternal laws of nature. The woman, refusing to be a woman, engenders devils; the man, trying to be a God, loses paradise and his innocence, for the element of the supernatural intruded upon him and abstracted his thoughts from this earth. These were the half idealistic and half realistic elements from which the three greatest spiritual incarnations of the Evil Spirit sprung up. Luther took the Evil Spirit as a bodily entity, with big horns, fiery eyes, a reddish, protruding tongue, a long tail, and the hoof of a horse. In this latter attribute we trace at once the Kentaur element of ancient times. Through nearly one thousand three hundred years from Tertullian and Thaumaturgus down to Luther, every one was accustomed to look upon life as one great battle with tens of thousands of devils, assaulting, harassing, annoying, and seducing humanity. All fought, quarrelled, talked, and wrestled with the Devil. He was more spoken of in the pulpits of the Christian Churches, written about in theological and scientific books, than God or Christ. All misfortunes were attributed to him. Thunder and lightning, hailstorms and the rinderpest, the hooping cough and epileptic fits were all the Devil's work. A man who suffered from madness was said to be possessed by a legion of Evil Spirits. The Devil settled himself in the gentle dimples of a pretty girl with the same ease and comfort as in the wrinkles of an old woman. Everything that was inexplicable was evil. Throughout the Middle Ages the masses and the majority of their learned theological teachers believed the Greek and Latin classics were inspired by Evil Spirits; that sculptures or paintings, if beautiful, were of evil; that all cleverness in Mathematics, Chemistry, or Medicine proved the presence of the corrupting Evil Spirit working in man. Any bridge over a chasm or a rapid river was the work of the Devil; even the most beautiful Gothic cathedrals, like those of Cologne and St. Stephen at Vienna were constructed by architects who served their apprenticeship in the infernal regions. The Devil sat grinning on the inkstands of poets and learned men, dictating to the poor deluded mortals, as the price for their souls, charming love-songs or deep theological and philosophical essays. It was extremely dangerous during this period of man's historical evolution to be better or wiser than the ignorant masses. Learning, talent, a superior power of reasoning, love for truth, a spirit of inquiry, the capacity of making money by clever trading, an artistic turn of mind, success in life, even in the Church, were only so many proofs that the soul had been sold to some dwarfish or giant messenger from Lucifer, who could appear in a thousand different forms. Man was, since his assumed Fall, the exclusive property of the coarse and vulgar conception of the Evil Spirit. Luther was full of these ideas, he was brought up in this belief, and though he unconsciously felt that the Devil ought to be expelled from our creed, he did not dare to attempt the reform of humanity by annihilating the mischief-maker: he could not rob man of his dearest spiritual possession; had he thought of consigning the Devil to the antediluvian period of our moral and social formation, he never could have succeeded in his reform. The Devil, in fact, was his strongest helpmate; he could describe the ritual of the Romish Church as the work of the Evil Spirit, produced to delude mankind. The Devil had his Romish prayers, his processions, his worship of relics, his remission of sins, his confessional, his infernal synods; he was to Luther an active, rough, and material incarnation of the roaring lion of the Scriptures in the shape of the Romish Church, walking about visibly, tangibly, bodily amongst men, devouring all who believed in the Pope, and who disbelieved in this stupid phantom of a dogmatically blinded imagination.

The Evolution-theory may be clearly traced in the two next conceptions: Milton's Satan and Goethe's Mephistopheles. They differ as strongly as the periods and the poems in which they appear. Milton's Satan loses the vulgar flesh and bone, horn and hoof nature—he is an epic character; whilst Goethe's Devil is an active dramatic entity of modern times. Milton's representative of evil is a very powerful conception—it is evil in abstracto; whilst Mephistopheles is evil in concreto—the intelligible, tangible Devil, evolved by the power of selection from an antediluvian monster, and transformed through a civilizing process of at least six thousand years into its present form. Milton's Satan is a debased intellect who in his boundless ambition is still a supernatural being. Mephistopheles is the incarnation of our complicated modern social evils, full of petty tricks and learned quotations; he piously turns up his eyes, he lies, doubts, calumniates, seduces, philosophizes, sneers, but all in a polite and highly educated way; he is a scholar, a divine, a politician, a diplomatist. Satan is capable of wild enthusiasm, he sometimes remembers his bright sinless past; "from the lowest deep," he yearns, "once more to lift himself up, in spite of fate, nearer to his ancient seat;"—he hopes to re-enter heaven, "to purge off his gloom;" some remnant of heavenly innocence still clings to him, for, though fallen, he is still an angel! Mephistopheles in his real nature is without any higher aspirations, he argues with a sarcastic smile on his lips, he is ironical with sophisticated sharpness. Satan has unconsciously gigantic ideas, he is ready to wrestle with God for the dominion of heaven. Mephistopheles is perfectly conscious of his littleness as opposed to our better intellectual nature, and does evil for evil's sake. Satan is sublime through the grandeur of his primitive elements, pride and ambition. Mephistopheles is only grave in his pettiness; he does not refuse an orgie with drunken students, indulges in jokes with monkeys, works miracles in the witch's kitchen, delights in the witch's "one-time-one;" distributes little tracts "to stir up the witch's heart with special fire." Satan has nothing vulgar in him: he is capable of melancholy feelings, he can be pathetic and eloquent. Mephistopheles laughs at the stupidity of the world, and at his own. Satan believes in God and in himself, whilst Mephistopheles is the "Spirit that denies;" he believes neither in God nor in heaven nor in hell; he does not believe in his own entity—he is no supernatural, fantastic being, but man incarnate: he is the evil part of a good whole, which loses its entity when once seen and recognised in its real nature; for Mephistopheles in reality is our own ignorant, besotted, animal nature, cultivated and developed at the expense of our intellectual part.

Luther's devil is the outgrowth of humanity in long-clothes. Man, ignorant of the forces of the Cosmos, blinded by theological dialectics and metaphysical subtleties, incapable of understanding the real essence of our moral and intellectual nature, philosophically untrained to observe that evil is but a sequence of the disturbed balance between our double nature—spirit and matter—attributed all mischief in the intellectual as well as in our social spheres to an absolute powerful being who continually tormented him.

Milton's Satan is the poetical conception of man developed from an infant in long-clothes into a boisterous but dreamy youth, ascribing to every incomprehensible effect an arbitrary, poetical cause. Goethe's Mephistopheles, lastly is the truthful conception of evil as it really exists in a thousand forms, evolved from our own misunderstood and artificially and dogmatically distorted nature.
