A dead cow or sheep lying in a pasture is recognized as carrion. The same sort of a carcass dressed and hung up in a butcher's stall passes as food.
— John Harvey Kellogg

A government, for protecting business only, is but a carcass, and soon falls by its own corruption and decay.
Amos Bronson Alcott carcass quote

The consciousness of being deemed dead, is next to the presumable unpleasantness of being so in reality. One feels like his own ghost unlawfully tenanting a defunct carcass.
— Herman Melville

We should not say that one man's hour is worth another man's hour, but rather that one man during an hour is worth just as much as another man during an hour. Time is everything, man is nothing: he is at the most time's carcass.
— Karl Marx

[Vultures are] our natural garbage collectors. They clean up carcasses right to the bone.
