Plutarch De esu carnium I 4

[4] But we are nothing put out of countenance, either by the beauteous gayety of the colors, or by the charmingness of the musical voices, or by the rare sagacity of the intellects, or by the cleanliness and neatness of diet, or by the rare discretion and prudence of these poor unfortunate animals; but for the sake of some little mouthful of flesh, we deprive a soul of the sun and light, and of that proportion of life and time it had been born into the world to enjoy. And then we fancy that the voices it utters and screams forth to us are nothing else but certain inarticulate sounds and noises, and not the several deprecations, entreaties, and pleadings of each of them, as it were saying thus to us: I deprecate not thy necessity (if such there be), but thy wantonness. Kill me for thy feeding, but do not take me off for thy better feeding. O horrible cruelty! It is truly an affecting sight to see the very table of rich people laid before them, who keep them cooks and caterers to furnish them with dead corpses for their daily fare; but it is yet more affecting to see it taken away, for the mammocks left are more than that which was eaten. These therefore were slain to no purpose. Others there are, who are so sparing of what is set before them that they will not suffer it to be cut or sliced; thus abstaining from them when dead, -while they would not spare them when alive.
