II. Let us now consider in what sense we are commanded to love our neighbour as ourselves.

This precept, in its first delivery by our Saviour, is thus introduced:—Thou shalt love the Lord thy God with all thine heart, with all thy soul, and with all thy strength; and thy neighbour as thyself. These very different manners of expression do not lead our thoughts to the same measure or degree of love, common to both objects, but to one peculiar to each. Supposing, then, which is to be supposed, a distinct meaning and propriety in the words, as thyself; the precept we are considering will admit of any of these senses: that we bear the same kind of affection to our neighbour as we do to ourselves, or, that the love we bear to our neighbour should have some certain proportion or other to self-love: or, lastly, that it should bear the particular proportion of equality, that it be in the same degree.

First, The precept may be understood as requiring only that we have the same kind of affection to our fellow-creatures as to ourselves; that, as every man has the principle of self-love, which disposes him to avoid misery, and consult his own happiness, so we should cultivate the affection of goodwill to our neighbour, and that it should influence us to have the same kind of regard to him. This at least must be commanded, and this will not only prevent our being injurious to him, but will also put us upon promoting his good. There are blessings in life, which we share in common with others, peace, plenty, freedom, healthful seasons. But real benevolence to our fellow-creatures would give us the notion of a common interest in a stricter sense, for in the degree we love another, his interest, his joys and sorrows, are our own. It is from self-love that we form the notion of private good, and consider it is our own: love of our neighbour would teach us thus to appropriate to ourselves his good and welfare; to consider ourselves as having a real share in his happiness. Thus the principle of benevolence would be an advocate within our own breasts, to take care of the interests of our fellow-creatures in all the interfering and competitions which cannot but be, from the imperfection of our nature, and the state we are in. It would likewise, in some measure, lessen that interfering, and hinder men from forming so strong a notion of private good, exclusive of the good of others, as we commonly do. Thus, as the private affection makes us in a peculiar manner sensible of humanity, justice or injustice, when exercised towards ourselves, love of our neighbour would give us the same kind of sensibility in his behalf. This would be the greatest security of our uniform obedience to that most equitable rule. Whatsoever ye would that men should do unto you, do ye even so unto them.

All this is indeed no more than that we should have a real love to our neighbour; but then, which is to be observed, the words as thyself express this in the most distinct manner, and determine the precept to relate to the affection itself. The advantage which this principle of benevolence has over other remote considerations is, that it is itself the temper of virtue, and likewise that it is the chief, nay, the only effectual security of our performing the several offices of kindness we owe to our fellow-creatures. When from distant considerations men resolve upon any thing to which they have no liking, or perhaps an averseness, they are perpetually finding out evasions and excuses, which need never be wanting, if people look for them: and they equivocate with themselves in the plainest cases in the world. This may be in respect to single determinate acts of virtue, but it comes in much more, where the obligation is to a general course of behaviour, and most of all, if it be such as cannot be reduced to fixed determinate rules. This observation may account for the diversity of the expression in that known passage of the prophet Micah, to do justly, and to love mercy. A man’s heart must be formed to humanity and benevolence, he must love mercy, otherwise he will not act mercifully in any settled course of behaviour. As consideration of the future sanctions of religion is our only security of preserving in our duty, in cases of great temptation: so to get our heart and temper formed to a love and liking of what is good is absolutely necessary in order to our behaving rightly in the familiar and daily intercourses amongst mankind.

Secondly, The precept before us may be understood to require that we love our neighbour in some certain proportion or other, according as we love ourselves. And indeed a man’s character cannot be determined by the love he bears to his neighbour, considered absolutely, but the proportion which this bears to self-love, whether it be attended to or not, is the chief thing which forms the character and influences the actions. For, as the form of the body is a composition of various parts, so likewise our inward structure is not simple or uniform, but a composition of various passions, appetites, affections, together with rationality, including in this last both the discernment of what is right, and a disposition to regulate ourselves by it. There is greater variety of parts in what we call a character than there are features in a face, and the morality of that is no more determined by one part than the beauty or deformity of this is by one single feature: each is to be judged of by all the parts or features, not taken singly, but together. In the inward frame the various passions, appetites, affections, stand in different respects to each other. The principles in our mind may be contradictory, or checks and allays only, or incentives and assistants to each other. And principles, which in their nature have no kind of contrariety or affinity, may yet accidentally be each other’s allays or incentives.

From hence it comes to pass, that though we were able to look into the inward contexture of the heart, and see with the greatest exactness in what degree any one principle is in a particular man, we could not from thence determine how far that principle would go towards forming the character, or what influence it would have upon the actions, unless we could likewise discern what other principles prevailed in him, and see the proportion which that one bears to the others. Thus, though two men should have the affection of compassion in the same degree exactly, yet one may have the principle of resentment or of ambition so strong in him as to prevail over that of compassion, and prevent its having any influence upon his actions, so that he may deserve the character of a hard or cruel man, whereas the other having compassion in just the same degree only, yet having resentment or ambition in a lower degree, his compassion may prevail over them, so as to influence his actions, and to denominate his temper compassionate. So that, how strange soever it may appear to people who do not attend to the thing, yet it is quite manifest that, when we say one man is more resenting or compassionate than another, this does not necessarily imply that one has the principle of resentment or of compassion stronger than the other. For if the proportion which resentment or compassion bears to other inward principles is greater in one than in the other, this is itself sufficient to denominate one more resenting or compassionate than the other.

Further, the whole system, as I may speak, of affections (including rationality), which constitute the heart, as this word is used in Scripture and on moral subjects, are each and all of them stronger in some than in others. Now the proportion which the two general affections, benevolence and self-love, bear to each other, according to this interpretation of the text, demonstrates men’s character as to virtue. Suppose, then, one man to have the principle of benevolence in a higher degree than another; it will not follow from hence that his general temper or character or actions will be more benevolent than the other’s. For he may have self-love in such a degree as quite to prevail over benevolence, so that it may have no influence at all upon his action, whereas benevolence in the other person, though in a lower degree, may yet be the strongest principle in his heart, and strong enough to be the guide of his actions, so as to denominate him a good and virtuous man. The case is here as in scales: it is not one weight considered in itself, which determines whether the scale shall ascend or descend, but this depends upon the proportion which that one weight hath to the other.

It being thus manifest that the influence which benevolence has upon our actions, and how far it goes towards forming our character, is not determined by the degree itself of this principle in our mind, but by the proportion it has to self-love and other principles: a comparison also being made in the text between self-love and the love of our neighbour; these joint considerations afforded sufficient occasion for treating here of that proportion. It plainly is implied in the precept, though it should be questioned, whether it be the exact meaning of the words, as thyself.

Love of our neighbour, then, must bear some proportion to self-love, and virtue, to be sure, consists in the due proportion. What this due proportion is, whether as a principle in the mind, or as exerted in actions, can be judged of only from our nature and condition in this world. Of the degree in which affections and the principles of action, considered in themselves, prevail, we have no measure: let us, then, proceed to the course of behaviour, the actions they produce.

Both our nature and condition require that each particular man should make particular provision for himself: and the inquiry, what proportion benevolence should have to self-love, when brought down to practice, will be, what is a competent care and provision for ourselves? And how certain soever it be that each man must determine this for himself, and how ridiculous soever it would be for any to attempt to determine it for another, yet it is to be observed that the proportion is real, and that a competent provision has a bound, and that it cannot be all which we can possibly get and keep within our grasp, without legal injustice. Mankind almost universally bring in vanity, supplies for what is called a life of pleasure, covetousness, or imaginary notions of superiority over others, to determine this question: but every one who desires to act a proper part in society would do well to consider how far any of them come in to determine it, in the way of moral consideration. All that can be said is, supposing what, as the world goes, is so much to be supposed that it is scarce to be mentioned, that persons do not neglect what they really owe to themselves; the more of their care and thought and of their fortune they employ in doing good to their fellow-creatures the nearer they come up to the law of perfection, Thou shalt love thy neighbour as thyself.
