Animal pain

Abstract

The attribution of conscious pain to nonhuman animals serves as a critical junction for animal welfare law and the philosophy of mind. Existing legal standards frequently employ anthropocentric benchmarks that ignore species-specific sensory variations, while philosophical inquiries often rely on simplistic analogies or speculative evolutionary accounts. Higher-order thought theories that deny phenomenal consciousness to non-human species based on a lack of “mind-reading” capabilities fail to account for the diverse functions of sensory integration across different taxa. Furthermore, evidence that isolated spinal cord mechanisms can support complex associative learning indicates that behavioral responses to noxious stimuli are not inherently indicative of conscious experience. Progress in determining the distribution of pain across the animal kingdom necessitates a move toward a more sophisticated biological functionalism. This approach must integrate neurobiological evidence of distributed processing with a nuanced understanding of how conscious pain facilitates specific forms of evaluative learning and behavioral plasticity. Only by developing case-sensitive, theoretically grounded criteria can a defensible framework for the ethical treatment and legal protection of diverse species be established. – AI-generated abstract.
