The relation which the several parts or members of the natural body have to each other and to the whole body is here compared to the relation which each particular person in society has to other particular persons and to the whole society; and the latter is intended to be illustrated by the former. And if there be a likeness between these two relations, the consequence is obvious: that the latter shows us we were intended to do good to others, as the former shows us that the several members of the natural body were intended to be instruments of good to each other and to the whole body. But as there is scarce any ground for a comparison between society and the mere material body, this without the mind being a dead unactive thing, much less can the comparison be carried to any length. And since the apostle speaks of the several members as having distinct offices, which implies the mind, it cannot be thought an allowable liberty, instead of the _body_ and _its members_, to substitute the _whole nature_ of _man_, and _all the variety of internal principles which belong to it_. And then the comparison will be between the nature of man as respecting self, and tending to private good, his own preservation and happiness; and the nature of man as having respect to society, and tending to promote public good, the happiness of that society. These ends do indeed perfectly coincide; and to aim at public and private good are so far from being inconsistent that they mutually promote each other: yet in the following discourse they must be considered as entirely distinct; otherwise the nature of man as tending to one, or as tending to the other, cannot be compared. There can no comparison be made, without considering the things compared as distinct and different. From this review and comparison of the nature of man as respecting self and as respecting society, it will plainly appear that _there are as real and the same kind of indications in human nature_, _that we were made for society and to do good to our fellow-creatures_, _as that we were intended to take care of our own life and health and private good_: _and that the same objections lie against one of these assertions as against the other_.
