Note 15 — Chapter VIII

It is, then, quite certain that compassion is a natural feeling, which checking, as it does, the love of self in each individual, helps by a reciprocal process to preserve the whole race. This it is, which in the state of nature, takes the place of laws, customs, and virtues, with the added advantage that no one will be tempted to disobey its gentle voice; this it is, which will restrain every able-bodied savage, provided he hope to find his own livelihood elsewhere, from robbing a weak child, or depriving an infirm old man of the subsistence won by hard toil; this it is, which inspires all men, not indeed with that sublime maxim of reasoned justice: "Do to others as you would they should do unto you;" but with another rule of natural goodness, no doubt less perfect, but perhaps more useful, namely: "Do what is good for yourself with the least possible harm to others." In a word, it is in this natural feeling rather than in subtle arguments that we must look for the reason of the repugnance with which every one is accustomed to view bad conduct, quite independently of the principles laid down by education.
