scarce knew how to distinguish the different orders of beings, by looking upon his species as of the highest order, he prepared the way for assuming pre-eminence as an individual.
Other men, it is true, were not then to him what they now are to us, and he had no greater intercourse with them than with other animals; yet they were not neglected in his observations. The conformities, which he would in time discover between them, and between himself and his female, led him to judge of others which were not then perceptible; and finding that they all behaved as he himself would have done in like circumstances, he naturally inferred that their manner of thinking and acting was altogether in conformity with his own. This important truth, once deeply impressed on his mind, must have induced him, from an intuitive feeling more certain and much more rapid than any kind of reasoning, to pursue the rules of conduct, which he had best observe towards them, for his own security and advantage.
Taught by experience that the love of well-being is the sole motive of human actions, he found himself in a position to distinguish the few cases, in which mutual interest might justify him in relying upon the assistance of his fellows; and also the still fewer cases in which a conflict of interests might give cause to suspect them. In the former case, he joined in the same herd with them, or at most in some kind of loose association, that laid no restraint on its members, and lasted no longer than the transitory occasion that formed it. In the latter case, every one sought his own private advantage, either by open force, if he thought himself strong enough, or by address and cunning, if he felt himself the weaker.
In this manner, men may have insensibly acquired some gross ideas of mutual undertakings, and of the advantages of fulfilling them: that is, just so far as their present and apparent interest was concerned: for they were perfect strangers to foresight, and were so far from troubling themselves about the distant future, that they hardly thought of the morrow. If a deer was to be taken, every one saw that, in order to succeed, he must abide faithfully by his post: but if a hare happened to come within the reach of any one of them, it is not to be doubted that he pursued it without scruple, and, having seized his prey, cared very little, if by so doing he caused his companions to miss theirs.
