„Among the reforms necessary for the triumph of true refinement and true morality, which ought to be our earnest aim, is the Dietetic one, which, if not the weightiest of all (allerwichtigste), yet, undoubtedly, is one of the weightiest. Still is the ‘civilised’ world stained and defiled by the remains of a horrible barbarity; while the old-world revolting practice of slaughter of animals and feeding on their corpses still is in so universal vogue, that men have not the faculty even of recognising it as such, as otherwise they would recognise it; and aversion from this horror provokes censure of such eccentricity, and amazement at any manifestation of tendency to reform, as at something absurd and ridiculous — nay, arouses even bitterness and hate. To extirpate this barbarism is a task, the accomplishment of which lies in the closest relationship with the most important principles of humaneness, morality, æsthetics, and physiology. A foundation for real culture — a thorough civilising and refining of humanity — is clearly impossible so long as an organised system of murder and of corpse-eating (organiserten Mord-und-Leichenfratz System) prevails by recognised custom.“
— Georg Friedrich Daumer
