The structure of the human frame then is that of one fitted to a pure vegetable diet, in every essential particular. It is true that the reluctance to abstain from animal food, in those who have been long accustomed to its stimulus, is so great in some persons of weak minds, as to be scarcely overcome; but this is far from bringing any argument in its favour. A lamb which was fed for some time on flesh by a ship's crew, refused its natural diet at the end of the voyage. There are numerous instances of horses, sheep, oxen, and even wood-pigeons, having been taught to live upon flesh, until they have loathed their natural aliment. Young children evidently prefer pastry, oranges, apples, and other fruit, to the flesh of animals, until, by the gradual depravation of the digestive organs, the free use of vegetables has, for a time, produced serious inconveniences; for a time, I say, since there never was an instance wherein a change from spirituous liquors and animal food to vegetables and pure water, has failed ultimately to invigorate the body, by rendering its juices bland and consentaneous, and to restore to the mind that cheerfulness and elasticity, which not one in fifty possesses on the present system. A love of strong liquors is also with difficulty taught to infants. Almost every one remembers the wry faces the first glass of port produced. Unsophisticated instinct is invariably unerring; but to decide on the fitness of animal food, from the perverted appetites which its constrained adoption produce, is to make the criminal a judge in his own cause; it is even worse, it is appealing to the infatuated drunkard in a question of the salubrity of brandy.
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 remains 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, bloodshot 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 at the mountain stream, 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 drank at the pure source of the Seine, and satisfied their hunger at the ever-furnished table of vegetable nature that 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 fè? 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 Bonaparte descended from a race of vegetable feeders, that he could have 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 tyrannise would certainly not be delegated by a society neither frenzied by inebriation, nor rendered impotent or 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 civilised life. Even common water, that apparently innoxious pabulum, when corrupted by the filth of populous cities, is a deadly and insidious destroyer.[5] 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, apparently favourable to the intolerant and angry passions, 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.
There is no disease, bodily or mental, which adoption of vegetable diet and pure water has not infallibly mitigated, wherever the experiment has been fairly tried. Debility is gradually converted into strength, disease into healthfulness: madness, in all its hideous variety, from the ravings of the fettered maniac, to the unaccountable irrationalities of ill-temper, that make a hell of domestic life, into a calm and considerable evenness of temper, that alone might offer a certain pledge of the future moral reformation of society. On a natural system of diet, old age would be our last and our only malady: the term of our existence would be protracted; we should enjoy life, and no longer preclude others from the enjoyment of it; all sensational delights would be infinitely more exquisite and perfect; the very sense of being would then be a continued pleasure, such as we now feel it in some few and favoured moments of our youth. By all that is sacred in our hopes for the human race, I conjure those who love happiness and truth, to give a fair trial to the vegetable system. Reasoning is surely superfluous on a subject whose merits an experience of six months would set for ever at rest. But it is only among the enlightened and benevolent that so great a sacrifice of appetite and prejudice can be expected, even though its ultimate excellence should not admit of dispute.
It is found easier, by the short-sighted victims of disease, to palliate their torments by medicine, than to prevent them by regimen. The vulgar of all ranks are invariably sensual and indocile; yet I cannot but feel myself persuaded, that when the benefits of vegetable diet are mathematically proved; when it is as clear, that those who live naturally are exempt from premature death, as that nine is not one, the most sottish of mankind will feel a preference towards a long and tranquil, contrasted with a short and painful life. On the average, out of sixty persons, four die in three years. In April, 1814, a statement will be given that sixty persons, all having lived more than three years on vegetables and pure water, are then in perfect health. More than two years have now elapsed; not one of them has died; no such example will be found in any sixty persons taken at random. Seventeen persons of all ages (the families of Dr. Lambe and Mr. Newton) have lived for seven years on this diet without a death, and almost without the slightest illness. Surely, when we consider that some of these were infants, and one a martyr to asthma, now nearly subdued, we may challenge any seventeen persons taken at random in this city to exhibit a parallel case. Those who may have been excited to question the rectitude of established habits of diet, by these loose remarks, should consult Mr. Newton's luminous and eloquent essay.[6] It is from that book, and from the conversation of its excellent and enlightened author, that I have derived the materials which I here present to the public.
