It is however worth while to remark, that this contrariety of passions would be attended with but small danger, did it not concur with a peculiarity in our outward circumstances, which affords it an opportunity of exerting itself.  There are different species of goods, which we are possessed of; the internal satisfaction of our minds, the external advantages of our body, and the enjoyment of such possessions as we have acquired by our industry and good fortune.  We are perfectly secure in the enjoyment of the first.  The second may be ravished from us, but can be of no advantage to him who deprives us of them.  The last only are both exposed to the violence of others, and may be transferred without suffering any loss or alteration; while at the same time, there is not a sufficient quantity of them to supply every one’s desires and necessities.  As the improvement, therefore, of these goods is the chief advantage of society, so the instability of their possession, along with their scarcity, is the chief impediment.

In vain should we expect to find, in uncultivated nature, a remedy to this inconvenience; or hope for any inartificial principle of the human mind, which might controul those 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 tye 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 corners 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
