absolute security and without the smallest inconvenience. Though they are almost naked, Francis Corréal tells us, they expose themselves freely in the woods, armed only with bows and arrows; but no one has ever heard of one of them being devoured by wild beasts.
But man has other enemies more formidable, against which is is not provided with such means of defence: these are the natural infirmities of infancy, old age, and illness of every kind, melancholy proofs of our weakness, of which the two first are common to all animals, and the last belongs chiefly to man in a state of society. With regard to infancy, it is observable that the mother, carrying her child always with her, can nurse it with much greater ease than the females of many other animals, which are forced to be perpetually going and coming, with great fatigue, one way to find subsistence, and another to suckle or feed their young. It is true that if the woman happens to perish, the infant is in great danger of perishing with her; but this risk is common to many other species of animals, whose young take a long time before they are able to provide for themselves. And if our infancy is longer than theirs, our lives are longer in proportion; so that all things are in this respect fairly equal; though there are other rules to be considered regarding the duration of the first period of life, and the number of young, which do not affect the present subject. In old age, when men are less active and perspire little, the need for food diminishes with the ability to provide it. As the savage state also protects them from gout and rheumatism, and old age is, of all ills, that which human aid can least alleviate, they cease to be, without others perceiving that they are no more, and almost without perceiving it themselves.
With respect to sickness, I shall not repeat the vain and false declamations which most healthy people pronounce against medicine; but I shall ask if any solid observations have been made from which it may be justly concluded that, in the countries where the art of medicine is most neglected, the mean duration of man's life is less than in those where it is most cultivated. How indeed can this be the case, if we bring on ourselves more diseases than medicine can furnish remedies? The great inequality in manner of living, the extreme idleness of some, and the excessive labour of others, the easiness of exciting and gratifying our sensual
