The other argument, which is founded on a man’s knowledge of his own existence, stands thus. A man knows not only that he now is, but that once he was not; consequently there must have been a cause. But our idea of causation is alone derivable from the constant conjunction of objects and the consequent inference of one from the other; and, reasoning experimentally, we can only infer from effects, causes exactly adequate to those effects. But there certainly is a generative power which is effected by certain instruments: we cannot prove that it is inherent in these instruments; nor is the contrary hypothesis capable of demonstration: we admit that the generative power is incomprehensible; but to suppose that the same effect is produced by an eternal, omniscient, omnipotent being, leaves the cause in the same obscurity, but renders it more incomprehensible.

  3d. Testimony. It is required that testimony should not be contrary to reason. The testimony that the Deity convinces the senses of men of his existence can only be admitted by us, if our mind considers it less probable that these men should have been deceived, than that the Deity should have appeared to them. Our reason can never admit the testimony of men, who not only declare that they were eye-witnesses of miracles, but that the Deity was irrational; for he commanded that he should be believed, he proposed the highest rewards for faith, eternal punishments for disbelief. We can only command voluntary actions; belief is not an act of volition; the mind is even passive, or involuntarily active: from this it is evident that we have no sufficient testimony, or rather that testimony is insufficient to prove the being of a God. It has been before shewn that it cannot be deduced from reason. They alone, then, who have been convinced by the evidence of the senses, can believe it.

  Hence it is evident that, having no proofs from either of the three sources of conviction, the mind cannot believe the existence of a creative God: it is also evident, that, as belief is a passion of the mind, no degree of criminality is attachable to disbelief; and that they only are reprehensible who neglect to remove the false medium through which their mind views any subject of discussion. Every reflecting mind must acknowledge that there is no proof of the existence of a Deity.

  Him, still from hope to hope the bliss pursuing,

  Which from the exhaustless lore of human weal

  Draws on the virtuous mind, the thoughts that rise

  In time-destroying infiniteness, gift

  With self-enshrined eternity, &c.

  Time is our consciousness of the succession of ideas in our mind. Vivid sensation, of either pain or pleasure, makes the time seem long, as the common phrase is, because it renders us more acutely conscious of our ideas. If a mind be conscious of an hundred ideas during one minute, by the clock, and of two hundred during another, the latter of these spaces would actually occupy so much greater extent in the mind as two exceed one in quantity. If, therefore, the human mind, by any future improvement of its sensibility, should become conscious of an infinite number of ideas in a minute, that minute would be eternity. I do not hence infer that the actual space between the birth and death of a man will ever be prolonged; but that his sensibility is perfectible, and that the number of ideas which his mind is capable of receiving is indefinite. One man is stretched on the rack during twelve hours; another sleeps soundly in his bed: the difference of time perceived by these two persons is immense; one hardly will believe that half an hour has elapsed, the other could credit that centuries had flown during his agony. Thus, the life of a man of virtue and talent, who should die in his thirtieth year, is, with regard to his own feelings, longer than that of a miserable priest-ridden slave, who dreams out a century of dulness. The one has perpetually cultivated his mental faculties, has rendered himself master of his thoughts, can abstract and generalize amid the lethargy of every-day business;—the other can slumber over the brightest moments of his being, and is unable to remember the happiest hour of his life. Perhaps the perishing ephemeron enjoys a longer life than the tortoise.

  Dark flood of time!

  Roll as it listeth thee—I measure not

  By months or moments thy ambiguous course.

  Another may stand by me on the brink

  And watch the bubble whirled beyond his ken

  That pauses at my feet. The sense of love,

  The thirst for action, and the impassioned thought

  Prolong my being: if I wake no more,

  My life more actual living will contain

  Than some grey veteran’s of the world’s cold school,

  Whose listless hours unprofitably roll,

  By one enthusiast feeling unredeemed.

  No longer now

  He slays the lamb that looks him in the face.

  I hold that the depravity of the physical and moral nature of man originated in his unnatural habits of life. The origin of man, like that of the universe of which he is a part, is enveloped in impenetrable mystery. His generations either had a beginning, or they had not. The weight of evidence in favour of each of these suppositions seems tolerably equal; and it is perfectly unimportant to the present argument which is assumed. The language spoken however by the mythology of nearly all religions seems to prove, that at some distant period man forsook the path of nature, and sacrificed the purity and happiness of his being to unnatural appetites. The date of this event seems to have also been that of some great change in the climates of the earth, with which it has an obvious correspondence. The allegory of Adam and Eve eating of the tree of evil, and entailing upon their posterity the wrath of God, and the loss of everlasting life, admits of no other explanation than the disease and crime that have flowed from unnatural diet. Milton was so well aware of this, that he makes Raphael thus exhibit to Adam the consequence of his disobedience.

  Immediately a place

  Before his eyes appeared: sad, noisome, dark:

  A lazar-house it seem’d; wherein were laid

  Numbers of all diseased: all maladies

  Of ghastly spasm, or racking torture, qualms

  Of heart-sick agony, all feverous kinds,

  Convulsions, epilepsies, fierce catarrhs,

  Intestine stone and ulcer, colic pangs,

  Daemoniac frenzy, moping melancholy,

  And moon-struck madness, pining atrophy,

  Marasmus, and wide-wasting pestilence,

  Dropsies, and asthmas, and joint-racking rheums.

  And how many thousands more might not be added to this frightful catalogue!

  The story of Prometheus is one likewise which, although universally admitted to be allegorical, has never been satisfactorily explained. Prometheus stole fire from heaven, and was chained for this crime to Mount
Caucasus, where a vulture continually devoured his liver, that grew to meet its hunger. Hesiod says, that, before the time of Prometheus, mankind were exempt from suffering; that they enjoyed a vigorous youth, and that death, when at length it came, approached like sleep, and gently closed their eyes. Again, so general was this opinion, that Horace, a poet of the Augustan age, writes—

  Audax omnia perpeti,

  Gens humana ruit per vetitum nefas;

  Audax Iapeti genus

  Ignem fraude malâ gentibus intulit:

  Post ignem aetheriâ domo

  Subductum, macies et nova febrium

  Terris incubuit cohors,

  Semotique prius tarda necessitas

  Lethi corripuit gradum.

  How plain a language is spoken by all this. Prometheus (who represents the human race) effected some great change in the condition of his nature, and applied fire to culinary purposes; thus inventing an expedient for screening from his disgust the horrors of the shambles. From this moment his vitals were devoured by the vulture of disease. It consumed his being in every shape of its loathsome and infinite variety, inducing the soul-quelling sinkings of premature and violent death. All vice arose from the ruin of healthful innocence. Tyranny, superstition, commerce, and inequality, were then first known, when reason vainly attempted to guide the wanderings of exacerbated passion. […]

  Man, and the animals whom he has infected with his society, or depraved by his dominion, are alone diseased. The wild hog, the mouflon, the bison, and the wolf, are perfectly exempt from malady, and invariably die either from external violence, or natural old age. But the domestic hog, the sheep, the cow, and the dog, are subject to an incredible variety of distempers; and, like the corrupters of their nature, have physicians who thrive upon their miseries. The supereminence of man is like Satan’s, a supereminence of pain; and the majority of his species, doomed to penury, disease and crime, have reason to curse the untoward event, that by enabling him to communicate his sensations, raised him above the level of his fellow animals. But the steps that have been taken are irrevocable. The whole of human science is comprised in one question:—How can the advantages of intellect and civilization be reconciled with the liberty and pure pleasures of natural life? How can we take the benefits, and reject the evils of the system, which is now interwoven with all the fibres of our being?—I believe that abstinence from animal food and spirituous liquors would in a great measure capacitate us for the solution of this important question.

  It is true, that mental and bodily derangement is attributable in part to other deviations from rectitude and nature than those which concern diet. The mistakes cherished by society respecting the connection of the sexes, whence the misery and diseases of unsatisfied celibacy, unenjoying prostitution, and the premature arrival of puberty necessarily spring; the putrid atmosphere of crowded cities; the exhalations of chemical processes; the muffling of our bodies in superfluous apparel; the absurd treatment of infants:—all these, and innumerable other causes, contribute their mite to the mass of human evil.

  Comparative anatomy teaches us that man resembles frugivorous animals in everything, and carnivorous in nothing; he has neither claws wherewith to seize his prey, nor distinct and pointed teeth to tear the living fibre. A Mandarin of the first class, with nails two inches long, would probably find them alone inefficient to hold even a hare. After every subterfuge of gluttony, the bull must be degraded into the ox, and the ram into the wether, by an unnatural and inhuman operation, that the flaccid fibre may offer a fainter resistance to rebellious nature. It is only by softening and disguising dead flesh by culinary preparation, that it is rendered susceptible of mastication or digestion; and that the sight of its bloody juices and raw horror does not excite intolerable loathing and disgust. Let the advocate of animal food force himself to a decisive experiment on its fitness, and, as Plutarch recommends, tear a living lamb with his teeth, and plunging his head into its vitals, slake his thirst with the steaming blood; when fresh from the deed of horror, let him revert to the irresistible instincts of nature that would rise in judgment against it, and say, Nature formed me for such work as this. Then, and then only, would he be consistent. […]

  [The passage omitted details the resemblances between human anatomy and that of herbivorous animals and remarks on the use of animal food and alcoholic beverages as acquired habits; when these are overcome, bodily and mental well-being naturally follow.]

  What is the cause of morbid action in the animal system? Not the air we breathe, for our fellow denizens of nature breathe the same uninjured; not the water we drink, (if remote from the pollutions of man and his inventions),* for the animals drink it too; not the earth we tread upon; not the unobscured sight of glorious nature, in the wood, the field, or the expanse of sky and ocean; nothing that we are or do in common with the undiseased inhabitants of the forest. Something then wherein we differ from them: our habit of altering our food by fire, so that our appetite is no longer a just criterion for the fitness of its gratification. Except in children, there remain no traces of that instinct which determines, in all other animals, what aliment is natural or otherwise; and so perfectly obliterated are they in the reasoning adults of our species, that it has become necessary to urge considerations drawn from comparative anatomy to prove that we are naturally frugivorous.

  Crime is madness. Madness is disease. Whenever the cause of disease shall be discovered, the root, from which all vice and misery have so long overshadowed the globe, will lie bare to the axe. All the exertions of man, from that moment, may be considered as tending to the clear profit of his species. No sane mind in a sane body resolves upon a real crime. It is a man of violent passions, blood-shot eyes, and swollen veins, that alone can grasp the knife of murder. The system of a simple diet promises no Utopian advantages. It is no mere reform of legislation, whilst the furious passions and evil propensities of the human heart, in which it had its origin, are still unassuaged. It strikes at the root of all evil, and is an experiment which may be tried with success, not alone by nations, but by small societies, families, and even individuals. In no cases has a return to vegetable diet produced the slightest injury; in most it has been attended with changes undeniably beneficial. Should ever a physician be born with the genius of Locke, I am persuaded that he might trace all bodily and mental derangements to our unnatural habits, as clearly as that philosopher has traced all knowledge to sensation. What prolific sources of disease are not those mineral and vegetable poisons that have been introduced for its extirpation! How many thousands have become murderers and robbers, bigots and domestic tyrants, dissolute and abandoned adventurers, from the use of fermented liquors; who, had they slaked their thirst only with pure water, would have lived but to diffuse the happiness of their own unperverted feelings. How many groundless opinions and absurd institutions have not received a general sanction from the sottishness and intemperance of individuals! Who will assert that, had the populace of Paris satisfied their hunger at the ever-furnished table of vegetable nature, they would have lent their brutal suffrage to the proscription-list of Robespierre? Could a set of men, whose passions were not perverted by unnatural stimuli, look with coolness on an auto da fé? Is it to be believed that a being of gentle feelings, rising from his meal of roots, would take delight in sports of blood? Was Nero a man of temperate life? could you read calm health in his cheek, flushed with ungovernable propensities of hatred for the human race? Did Muley Ismael’s pulse beat evenly, was his skin transparent, did his eyes beam with healthfulness, and its invariable concomitants, cheerfulness and benignity? Though history has decided none of these questions, a child could not hesitate to answer in the negative. Surely the bile-suffused cheek of Buonaparte, his wrinkled brow, and yellow eye, the ceaseless inquietude of his nervous system, speak no less plainly the character of his unresting ambition than his murders and his victories. It is impossible, had Buonaparte descended from a race of vegetable feeders, that he could have had either the inclination
or the power to ascend the throne of the Bourbons. The desire of tyranny could scarcely be excited in the individual, the power to tyrannize would certainly not be delegated by a society neither frenzied by inebriation nor rendered impotent and irrational by disease. Pregnant indeed with inexhaustible calamity is the renunciation of instinct, as it concerns our physical nature; arithmetic cannot enumerate, nor reason perhaps suspect, the multitudinous sources of disease in civilized life. Even common water, that apparently innoxious pabulum, when corrupted by the filth of populous cities, is a deadly and insidious destroyer.* Who can wonder that all the inducements held out by God Himself in the Bible to virtue should have been vainer than a nurse’s tale; and that those dogmas, by which he has there excited and justified the most ferocious propensities, should have alone been deemed essential; whilst Christians are in the daily practice of all those habits, which have infected with disease and crime, not only the reprobate sons, but these favoured children of the common Father’s love? Omnipotence itself could not save them from the consequences of this original and universal sin. […]

  The quantity of nutritious vegetable matter, consumed in fattening the carcase of an ox, would afford ten times the sustenance, undepraving indeed, and incapable of generating disease, if gathered immediately from the bosom of the earth. The most fertile districts of the habitable globe are now actually cultivated by men for animals, at a delay and waste of aliment absolutely incapable of calculation. It is only the wealthy that can, to any great degree, even now, indulge the unnatural craving for dead flesh, and they pay for the greater license of the privilege by subjection to supernumerary diseases. Again, the spirit of the nation that should take the lead in this great reform, would insensibly become agricultural; commerce, with all its vice, selfishness and corruption, would gradually decline; more natural habits would produce gentler manners, and the excessive complication of political relations would be so far simplified, that every individual might feel and understand why he loved his country, and took a personal interest in its welfare. How would England, for example, depend on the caprices of foreign rulers, if she contained within herself all the necessaries, and despised whatever they possessed of the luxuries of life? How could they starve her into compliance with their views? Of what consequence would it be that they refused to take her woollen manufactures, when large and fertile tracts of the island ceased to be allotted to the waste of pasturage? On a natural system of diet, we should require no spices from India; no wines from Portugal, Spain, France, or Madeira; none of those multitudinous articles of luxury, for which every corner of the globe is rifled, and which are the causes of so much individual rivalship, such calamitous and sanguinary national disputes. In the history of modern times, the avarice of commercial monopoly, no less than the ambition of weak and wicked chiefs, seems to have fomented the universal discord, to have added stubbornness to the mistakes of cabinets, and indocility to the infatuation of the people. Let it ever be remembered, that it is the direct influence of commerce to make the interval between the richest and the poorest man wider and more unconquerable. Let it be remembered, that it is a foe to every thing of real worth and excellence in the human character. The odious and disgusting aristocracy of wealth is built upon the ruins of all that is good in chivalry or republicanism; and luxury is the forerunner of a barbarism scarce capable of cure. Is it impossible to realize a state of society, where all the energies of man shall be directed to the production of his solid happiness? Certainly, if this advantage (the object of all political speculation) be in any degree attainable, it is attainable only by a community, which holds out no factitious incentives to the avarice and ambition of the few, and which is internally organized for the liberty, security and comfort of the many. None must be entrusted with power (and money is the completest species of power) who do not stand pledged to use it exclusively for the general benefit. But the use of animal flesh and fermented liquors, directly militates with this equality of the rights of man. The peasant cannot gratify these fashionable cravings without leaving his family to starve. Without disease and war, those sweeping curtailers of population, pasturage would include a waste too great to be afforded. The labour requisite to support a family is far lighter* than is usually supposed. The peasantry work, not only for themselves, but for the aristocracy, the army, and the manufacturers. […]
