Justifying The Precautionary Principle With Expected Net-Welfare Maximization, Yew-Kwang Ng Jan 2017

Justifying The Precautionary Principle With Expected Net-Welfare Maximization, Yew-Kwang Ng

Animal Sentience

The precautionary principle may be best justified on the principle of expected net-welfare/benefit maximization; there is no conflict between the two principles. We should want to be more cautious for cases with high benefit-to-cost ratios; there should thus be different degrees of precaution. For measures to reduce extinction-threatening environmental disruption or to reduce animal suffering that cost us little or nothing, we should adopt them even for species having only a small likelihood of being sentient, i.e., we should be more cautious. This argument is based on welfarism, which I strongly defend elsewhere (Ng 1990 & forthcoming).


Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala Jan 2017

Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala

Animal Sentience

It is not possible to demonstrate that dogs (Canis familiaris) feel emotions, but the same is true for all other species, including our own. The issue must therefore be approached indirectly, using premises similar to those used with humans. Recent methodological advances in canine research reveal what dogs experience and what they derive from the emotions perceptible in others. Dogs attend to social cues, they respond appropriately to the valence of human and dog facial expressions and vocalizations of emotion, and their limbic reward regions respond to the odor of their caretakers. They behave differently according to the …
