Quotation: The Rev. Dr. William Hamilton Drummond (1838)

"While we "eat the fat and drink the sweet," we never, for an instant reflect on the animal sufferings which precede the banquet;—the barbed hook, the lacerating shot, the shrieks, the groans, and the dying agony. Such reflections would embitter the taste; therefore they are excluded as enemies of our peace; and cruelties continue to be perpetrated not because we approve of them, but because we allow ourselves to become even unconscious of their existence."
