not repeat the vain and false declamations made use of to discredit medicine by most men, while they enjoy their health; I shall only ask if there are any solid observations from which we may conclude that in those countries where the healing art is most neglected, the mean duration of man's life is shorter than in those where it is most cultivated? And how is it possible this should be the case, if we inflict more diseases upon ourselves than medicine can supply us with remedies! The extreme inequalities in the manner of living of the several classes of mankind, the excess of idleness in some, and of labour in others, the facility of irritating and satisfying our sensuality and our appetites, the too exquisite and out of the way aliments of the rich, which fill them with fiery juices, and bring on indigestions, the unwholesome food of the poor, of which even, bad as it is, they very often fall short, and the want of which tempts them, every opportunity that offers, to eat greedily and overload their stomachs; watchings, excesses of every kind, immoderate transports of all the passions, fatigues, waste of spirits, in a word, the numberless pains and anxieties annexed to every condition, and which the mind of man is constantly a prey to; these are the fatal proofs that most of our ills are of our own making, and that we might have avoided them all by adhering to the simple, uniform and solitary way of life prescribed to us by nature. Allowing that nature intended we should always enjoy good health, I dare almost affirm that a state of reflection is a state against nature, and that the man who meditates is a depraved animal. We need only call to mind the good constitution of savages, of those at least whom we have not destroyed by our strong liquors; we need only reflect, that they are strangers to almost every disease, except those occasioned by wounds and old age, to be in a manner convinced that the history of human diseases might be easily composed by pursuing that of civil societies. Such at least was the opinion of Plato, who concluded from certain remedies made use of or approved by Podalyrus and Macaon at the Siege of Troy, that several disorders, which these remedies were found to bring on in his days, were not known among men at that remote period.
Man therefore, in a state of nature where there are so few sources of sickness, can have no great occasion for physic, and still less for physicians; neither is the human species more to be pitied in this respect, than any other species of animals. Ask those who make hunting their recreation or business, if in their excursions they meet with many sick or feeble animals. They meet with many carrying the marks of considerable wounds, that have been perfectly well healed and closed up; with many, whose bones formerly broken, and whose limbs almost torn off, have completely knit and united, without any other surgeon but time, any other regimen but their usual way of living, and whose cures were not the less perfect for their not having been tortured with incisions, poisoned with drugs, or worn out by diet and abstinence. In a word, however useful medicine well administered may be to us who live in a state of society, it is still past doubt, that if, on the one hand, the sick savage, destitute of help, has nothing to hope from nature, on the other, he has nothing to fear but from his disease; a circumstance, which oftens renders his situation preferable to ours.
Let us therefore beware of confounding savage man with the men, whom we daily see and converse with. Nature behaves towards all animals left to her care with a predilection, that seems to prove how jealous she is of that prerogative. The horse, the cat, the bull, nay the ass itself, have generally a higher stature, and always a more robust constitution, more vigour, more strength and courage in their forests than in our houses; they lose half these advantages by becoming domestic animals; it looks as if all our attention to treat them kindly, and to feed them well, served only to bastardize them. It is thus with man himself. In proportion as he becomes sociable and a slave to others, he becomes weak, fearful, mean-spirited, and his soft and effeminate way of living at once completes the enervation of his strength and of his courage. We may add, that there must be still a wider difference between man and man in a savage and domestic condition, than between beast and beast; for as men and beasts have been treated alike by nature, all the conveniences with which men indulge themselves more than they do the beasts tamed by them, are so many particular causes which make them degenerate more sensibly.
Nakedness therefore, the want of houses, and of all these unnecessaries, which we consider as so very necessary, are not such mighty evils in respect to these primitive men, and much less still any obstacle to their preservation. Their skins, it is true, are destitute of hair; but then they have no occasion for any such covering in warm climates; and in cold climates they soon learn to apply to that use those of the animals they have conquered; they have but two feet to run with, but they have two hands to defend themselves with, and provide for all their wants; it costs them perhaps a great deal of time and trouble to make their children walk, but the mothers carry them with ease; an advantage not granted to other species of animals, with whom the mother, when pursued, is obliged to abandon her young ones, or regulate her steps by theirs. In short, unless we admit those singular and fortuitous concurrences of circumstances, which I shall speak of hereafter, and which, it is very possible, may never have existed, it is evident, in every state of the question, that the man, who first made himself clothes and built himself a cabin, supplied himself with things which he did not much want, since he had lived without them till then; and why should he not have been able to support in his riper years, the same kind of life, which he had supported from his infancy?
Alone, idle, and always surrounded with danger, savage man must be fond of sleep, and sleep lightly like other animals, who think but little, and may, in a manner, be said to sleep all the time they do not think: self-preservation being almost his only concern, he must exercise those faculties most, which are most serviceable in attacking and in defending, whether to subdue his prey, or to prevent his becoming that of other animals: those organs, on the contrary, which softness and sensuality can alone improve, must remain in a state of rudeness, utterly incompatible with all manner of delicacy; and as his senses are divided on this point, his touch and his taste must be extremely coarse and blunt; his sight, his hearing, and his smelling equally subtle: such is the animal state in general, and accordingly if we may believe travellers, it is that of most savage nations. We must not therefore be surprised, that the Hottentots of the Cape of Good Hope, distinguish with their naked eyes ships on the ocean, at as great a distance as the Dutch can discern them with their glasses; nor that the savages of America should have tracked the Spaniards with their noses, to as great a degree of exactness, as the best dogs could have done; nor that all these barbarous nations support nakedness without pain, use such large quantities of Piemento to give their food a relish, and drink like water the strongest liquors of Europe.
As yet I have considered man merely in his physical capacity; let us now endeavour to examine him in a metaphysical and moral light.
I can discover nothing in any mere animal but an ingenious machine, to which nature has given senses to wind itself up, and guard, to a certain degree, against everything that might destroy or disorder it. I perceive the very same things in the human machine, with this difference, that nature alone operates in all the operations of the beast, whereas man, as a free agent, has a share in his. One chooses by instinct; the other by an act of liberty; for which reason the beast cannot deviate from the rules that have been prescribed to it, even in cases where such deviation might be useful, and man often deviates from the rules laid down for him to his prejudice. Thus a pigeon would starve near a dish of the best flesh-meat, and a cat on a heap of fruit or corn, though both might very well support life with the food which they thus disdain, did they but bethink themselves to make a trial of it: it is in this manner dissolute men run into excesses, which bring on fevers and death itself; because the mind depraves the senses, and when nature ceases to speak, the will still continues to dictate.
All animals must be allowed to have ideas, since all animals have senses; they even combine their ideas to a certain degree, and, in this respect, it is only the difference of such degree, that constitutes the difference between man and beast: some philosophers have even advanced, that there is a greater difference between some men and some others, than between some men and some beasts; it is not therefore so much the understanding that constitutes, among animals, the specifical distinction of man, as his quality of a free agent. Nature speaks to all animals, and beasts obey her voice. Man feels the same impression, but he at the same time perceives that he is free to resist or to acquiesce; and it is in the consciousness of this liberty, that the spirituality of his soul chiefly appears: for natural philosophy explains, in some measure, the mechanism of the senses and the formation of ideas; but in the power of willing, or rather of choosing,
