Alexander Bain,
Moral Science; a Compendium of Ethics
“ If we read History, and cast our glance over the world, we shall scarcely find any rule of Morality (excepting such as are necessary to hold society together, and these too with great limitations) but what is somewhere or other set aside, and an opposite established, by whole societies of men. Men may break a law without disowning it; but it is inconceivable that a whole nation should publicly reject and renounce what every one of them, certainly and infallibly, knows to be a law. Whatever practical principle is innate, must be known to every one to be just and good. ”
