If the question be put, What the mind of man could perform, when left to itself, and without the aid of any foreign direction? we are to look for our answer in the history of mankind. Particular experiments which have been found so useful in establishing the principles of other sciences, could probably, on this subject, teach us nothing important, or new: we are to take the history of every active being from his conduct in the situation to which he is formed, not from his appearance in any forced or uncommon condition; a wild man therefore, caught in the woods, where he had always lived apart from his species, is a singular instance, not a specimen of any general character. As the anatomy of an eye which had never received the impressions of light, or that of an ear which had never felt the impulse of sounds, would probably exhibit defects in the very structure of the organs themselves, arising from their not being applied to their proper functions; so any particular case of this sort would only shew in what degree the powers of apprehension and sentiment could exist where they had not been employed, and what would be the defects and imbecilities of a heart in which the emotions that pertain to society had never been felt.
Mankind are to be taken in groupes, as they have always subsisted. The history of the individual is but a detail of the sentiments and thoughts he has entertained in the view of his species: and every experiment relative to this subject should be made with entire societies, not with single men. We have every reason, however, to believe, that in the case of such an experiment made, we shall suppose, with a colony of children transplanted from the nursery, and left to form a society apart, untaught, and undisciplined, we should only have the same things repeated, which, in so many different parts of the earth, have been transacted already. The members of our little society would feed and sleep, would herd together and play, would have a language of their own, would quarrel and divide, would be to one another the most important objects of the scene, and, in the ardour of their friendships and competitions, would overlook their personal danger, and suspend the care of their self-preservation. Has not the human race been planted like the colony in question? Who has directed their course? whose instruction have they heard? or whose example have they followed?
Nature, therefore, we shall presume, having given to every animal its mode of existence, its dispositions and manner of life, has dealt equally with those of the human race; and the natural historian who would collect the properties of this species, may fill up every article now, as well as he could have done in any former age. yet one property by which man is distinguished, has been sometimes overlooked in the account of his nature, or has only served to mislead our attention. In other classes of animals, the individual advances from infancy to age or maturity; and he attains, in the compass of a single life, to all the perfection his nature can reach: but, in the human kind, the species has a progress as well as the individual; they build in every subsequent age on foundations formerly laid; and, in a succession of years, tend to a perfection in the application of their faculties, to which the aid of long experience is required, and to which many generations must have combined their endeavours. We observe the progress they have made; we distinctly enumerate many of its steps; we can trace them back to a distant antiquity of which no record remains, nor any monument is preserved, to inform us what were the openings of this wonderful scene. The consequence is, that instead of attending to the character of our species, where the particulars are vouched by the surest authority, we endeavour to trace it through ages and scenes unknown; and, instead of supposing that the beginning of our story was nearly of a piece with the sequel, we think ourselves warranted to reject every circumstance of our present condition and frame, as adventitious, and foreign to our nature.
The progress of mankind from a supposed state of animal sensibility, to the attainment of reason, to the use of language, and to the habit of society, has been accordingly painted with a force of imagination, and its steps have been marked with a boldness of invention, that would tempt us to admit, among the materials of history, the suggestions of fancy, and to receive, perhaps, as the model of our nature in its original state, some of the animals whose shape has the greatest resemblance to ours.(1*)It would be ridiculous to affirm, as a discovery, that the species of the horse was probably never the same with that of the lion; yet, in opposition to what has dropped from the pens of eminent writers, we are obliged to observe, that men have always appeared among animals a distinct and a superior race; that neither the possession of similar organs, nor the approximation of shape, nor the use of the hand,(2*) nor the continued intercourse with this sovereign artist, has enabled any other species to blend their nature or their inventions with his; that in his rudest state, he is found to be above them; and in his greatest degeneracy, never descends to their level. He is, in short, a man in every condition; and we can learn nothing of his nature from the analogy of other animals. If we would know him, we must attend to himself, to the course of his life, and the tenor of his conduct. With him the society appears to be as old as the individual, and the use of the tongue as universal as that of the hand or the foot. If there was a time in which he had his acquaintance with his own species to make, and his faculties to acquire, it is a time of which we have no record, and in relation to which our opinions can serve no purpose, and are supported by no evidence.
