What subjects for canonization and apotheosis! There is, however, a difference between us two-handed bipeds and other living creatures--what is it?
A student of philosophy would hasten to reply: "This difference lies in the fact that we are conscious of our social faculty, while the animals are unconscious of theirs--in the fact that while we reflect and reason upon the operation of our social instinct, the animals do nothing of the kind." I will go farther.

It is by our reflective and reasoning powers, with which we seem to be exclusively endowed, that we know that it is injurious, first to others and then to ourselves, to resist the social instinct which governs us, and which we call JUSTICE.

It is our reason which teaches us that the selfish man, the robber, the murderer--in a word, the traitor to society--sins against Nature, and is guilty with respect to others and himself, when he does wrong wilfully.

Finally, it is our social sentiment on the one hand, and our reason on the other, which cause us to think that beings such as we should take the responsibility of their acts.

Such is the principle of remorse, revenge, and penal justice.
But this proves only an intellectual diversity between the animals and man, not at all an affectional one; for, although we reason upon our relations with our fellows, we likewise reason upon our most trivial actions,--such as drinking, eating, choosing a wife, or selecting a dwelling-place.
