Secondly, had not men a natural sentiment of approbation and blame, it cou'd never be excited by politicians; nor wou'd the words laudable and praise-worthy, blameable and odious, be any more intelligible, than if they were a language perfectly unknown to us, as we have already observ'd. But tho' this system be erroneous, it may teach us, that moral distinctions arise, in a great measure, from the tendency of qualities and characters to the interests of society, and that 'tis our concem for that interest, which makes us approve or disapprove of them. Now we have no such extensive concern for society but from sympathy; and consequently 'tis that principle, which takes us so far out of ourselves, as to give us the same pleasure or uneasiness in the characters of others, as if they had a tendency to our own advantage or loss.

The only difference betwixt the natural virtues and justice lies in this, that the good, which results from the former, arises from every single act, and is the object of some natural passion: Whereas a single act of justice, consider'd in itself, may often be contrary to the public good; and 'tis only the concurrence of mankind, in a general scheme or system of action, which is advantageous. When I relieve persons in distress, my natural humanity is my motive; and so far as my succour extends, so far have I promoted the happiness of my fellow-creatures. But if we examine all the questions, that come before any tribunal of justice, we shall find, that, considering each case apart, it wou'd as often be an instance of humanity to decide contrary to the laws of justice as conformable to them. Judges take from a poor man to give to a rich; they bestow on the dissolute the labour of the industrious; and put into the hands of the vicious the means of harming both themselves and others. The whole scheme, however, of law and justice is advantageous to the society; and 'twas with a view to this advantage, that men, by their voluntary conventions, establish'd it. After it is once establish'd by these conventions, it is naturally attended with a
