Abstract
The problem of ascertaining whether there is a justification for the imposition of suffering and premature death on nonhuman animals is important in itself. Examination of the problem also promises to force philosophers to rethink widespread assumptions about what is proper treatment of less than normal human beings, the basis for attributing rights to humans, the value of life, the “intrinsic worth of all human beings,” and certain egalitarian principles. In what follows my primary concern will concern the justification of imposing suffering on animals. In particular I shall try to sort out and examine some arguments set forward by Tom Regan in a recent essay.
