But, in order to form society, 'tis requisite not only that it be advantageous, but also that men be sensible of these advantages; and 'tis impossible, in their wild uncultivated state, that by study and reflection alone they should ever be able to attain this knowledge. Most fortunately, therefore, there is conjoined to those necessities, whose remedies are remote and obscure, another necessity, which, having a present and more obvious remedy, may justly be regarded as the first and original principle of human society. This necessity is no other than that natural appetite betwixt the sexes, which unites them together, and preserves their union, till a new tie takes place in their concern for their common offspring. This new concern becomes also a principle of union betwixt the parents and offspring, and forms a more numerous society, where the parents govern by the advantage of their superior strength and wisdom, and at the same time are restrained in the exercise of their authority by that natural affection which they bear their children. In a little time, custom and habit, operating on the tender minds of the children, makes them sensible of the advantages which they may reap from society, as well as fashions them by degrees for it, by rubbing off those rough comers and untoward affections which prevent their coalition. For it must be confest, that however the circumstances of human nature may render an union necessary, and however those passions of lust and natural affection may seem to render it unavoidable, yet there are other particulars in our _natural temper_, and in our _outward circumstances_, which are very incommodious, and are even contrary to the requisite conjunction. Among the former we may justly esteem our _selfishness_ to be the most considerable. I am sensible that, generally speaking, the representations of this quality have been carried much too far; and that the descriptions which certain philosophers delight so much to form of mankind in this particular, are as wide of nature as any accounts of monsters which we meet with in fables and romances. So far from thinking that men have no affect ion for any thing beyond themselves, I am of opinion that, though it be rare to meet with one who loves any single person better than himself, yet 'tis as rare to meet with one in whom all the kind affections, taken together, do not overbalance all the selfish. Consult common experience; do you not see, that though the whole expense of the family be generally under the direction of the master of it, yet there are few that do not bestow the largest part of their fortunes on the pleasures of their wives and the education of their children, reserving the smallest portion for their own proper use and entertainment? This is what we may observe concerning such as have those endearing ties; and may presume, that the case would be the same with others, were they placed in a like situation.
