To aggravate the injury, add the circumstances of former friendship and obligation from the injured person; let the man who is supposed to have done these two different actions coolly reflect upon them afterwards, without regard to their consequences to himself: to assert that any common man would be affected in the same way towards these different actions, that he would make no distinction between them, but approve or disapprove them equally, is too glaring a falsity to need being confuted. There is therefore this principle of reflection or conscience in mankind. It is needless to compare the respect it has to private good with the respect it has to public; since it plainly tends as much to the latter as to the former, and is commonly thought to tend chiefly to the latter. This faculty is now mentioned merely as another part in the inward frame of man, pointing out to us in some degree what we are intended for, and as what will naturally and of course have some influence. The particular place assigned to it by nature, what authority it has, and how great influence it ought to have, shall be hereafter considered. From this comparison of benevolence and self-love, of our public and private affections, of the courses of life they lead to, and of the principle of reflection or conscience as respecting each of them, it is as manifest that _we were made for society_, _and to promote the happiness of it_, _as that we were intended to take care of our own life and health and private good_.
