"In law we draw a line between the killing of human animals and non-human ones, setting the latter apart as brutes. This was founded on a general belief that humans have immortal souls and brutes none. Nowadays more and more people are refusing to make this distinction. They may believe in The Life Everlasting and The Life to Come; but they make no distinction between Man and Brute, because some of them believe that brutes have souls, whilst others refuse to believe that the physical materializations and personifications of The Life Everlasting are themselves everlasting. In either case the mystic distinction between Man and Brute vanishes; and the murderer pleading that though a rabbit should be killed for being mischievous he himself should be spared because he has an immortal soul and a rabbit has none is as hopelessly out of date as a gentleman duellist pleading his clergy. When the necessity for killing a dangerous human being arises, as it still does daily, the only distinction we make between a man and a snared rabbit is that we very quaintly provide the man with a minister of religion to explain to him that we are not killing him at all, but only expediting his transfer to an eternity of bliss."
