Biol Philos (2013) 28:1–30 DOI 10.1007/s10539-012-9351-1 Science, sentience, and animal welfare Robert C. Jones Received: 8 April 2012 / Accepted: 1 November 2012 / Published online: 20 November 2012 Ó Springer Science+Business Media Dordrecht 2012 Abstract I sketch briefly some of the more influential theories concerned with the moral status of nonhuman animals, highlighting their biological/physiological aspects. I then survey the most prominent empirical research on the physiological and cognitive capacities of nonhuman animals, focusing primarily on sentience, but looking also at a few other morally relevant capacities such as self-awareness, memory, and mindreading. Lastly, I discuss two examples of current animal welfare policy, namely, animals used in industrialized food production and in scientific research. I argue that even the most progressive current welfare policies lag behind, are ignorant of, or arbitrarily disregard the science on sentience and cognition. Keywords Animal Á Welfare Á Ethics Á Pain Á Sentience Á Cognition Á Agriculture Á Speciesism Á Biomedical research Introduction The contemporary connection between research on animal1 cognition and the moral status of animals goes back almost 40 years to the publication of two influential books: Donald Griffin’s The Question of Animal Awareness: Evolutionary Continuity of Mental Experience (1976) and Peter Singer’s groundbreaking Animal Liberation (1975). Since then, there has been a staggering amount of work exploring the scientific and ethical dimensions of animal physiology and cognition. Almost all 1 I will use the terms ‘animals’ and ‘nonhuman animals’ interchangeably throughout the paper to refer to nonhuman animals. R. C.
