Animal Pain

The Montreal Declaration on Animal Exploitation, which has been endorsed by hundreds of influential academic ethicists, calls for establishing a vegan economy by banning what it refers to as all unnecessary animal suffering, including fishing. It does so by appeal to the moral principle of equal consideration of comparable interests. I argue that this principle is misapplied by discounting morally relevant cognitive capacities of self-conscious and volitional personhood as distinguished from merely sentient non-personhood. I describe it as a kind of (...) anthropomorphizing moralism which I call anthropomoralism, defined as the tendency to project morally relevant characteristics of personhood onto merely sentient non-persons by discounting their existing differences with actual persons. I show that this attitude can lend support to the resurgent attempt to treat fetal pain as equally morally considerable to that of childbearing persons they gestate within. I explain that the only sound way to apply the principle of equal consideration of comparable interests is to compare experiences of actual persons. Therefore, while supporting a vegan economy may be morally praiseworthy, it should not be deemed morally obligatory. (shrink)

Definitions of animal welfare often invoke consciousness or sentience. Marian Stamp Dawkins has argued that to define animal welfare this way is a mistake. In Dawkins’s alternative view, an animal with good welfare is one that is healthy and “has what it wants.” The dispute highlights a source of strain on the concept of animal welfare: consciousness-involving definitions are better able to capture the normative significance of welfare, whereas consciousness-free definitions facilitate the validation of welfare indicators. I reflect on how (...) the field should respond to this strain, ultimately recommending against splitting the concept and in favor of consciousness-involving definitions. (shrink)

We should be suspicious of the idea that experiencing pain could enable animals to trade off different motivations in a common currency. It is not even clear that humans have a common motivational currency reflected in evaluative experience. Instead, pain may capture attention, inhibiting attention to competing motivations and needs, thereby making genuine trade-offs harder. Our criteria for pain in invertebrates should be part of a more subtle theory of the relationship between pain and decision-making.

‘Sentience’ sometimes refers to the capacity for any type of subjective experience, and sometimes to the capacity to have subjective experiences with a positive or negative valence, such as pain or pleasure. We review recent controversies regarding sentience in fish and invertebrates and consider the deep methodological challenge posed by these cases. We then present two ways of responding to the challenge. In a policy-making context, precautionary thinking can help us treat animals appropriately despite continuing uncertainty about their sentience. In (...) a scientific context, we can draw inspiration from the science of human consciousness to disentangle conscious and unconscious perception (especially vision) in animals. Developing better ways to disentangle conscious and unconscious affect is a key priority for future research. (shrink)

I start by defining sentience and giving an analysis of the epistemological problems that plague its scientific study; this consists mainly in justifying that the attribution of sentience is underdetermined by the data. Second I show that as a result of this situation of underdetermination, most of the types of arguments used to infer sentience from the data are inconclusive and lead to a stalemate. Third, I argue that the stalemates arise from a foundationalist epistemology which needlessly leads to skeptical (...) conclusions; as an alternative, I propose to adopt a coherentist framework and defend a process of ‘epistemic iteration’ (Chang 2004) within that framework, which I argue gives us a way out of the underdetermination.

We have structured our response according to five questions arising from the commentaries: (i) What is sentience? (ii) Is sentience a necessary or sufficient condition for moral standing? (iii) What methods should guide comparative cognitive research in general, and specifically in studying invertebrates? (iv) How should we balance scientific uncertainty and moral risk? (v) What practical strategies can help reduce biases and morally dismissive attitudes toward invertebrates?

Affective experience in nonhuman animals is of great interest for both theoretical and practical reasons. This paper highlights research by the psychologists Anthony Dickinson and Bernard Balleine which provides particularly good evidence of conscious affective experience in rats. This evidence is compelling because it implicates a sophisticated system for goal-directed action selection, and demonstrates a contrast between apparently conscious and unconscious evaluative representations with similar content. Meanwhile, the evidence provided by some well-known studies on pain in nonhuman animals is much (...) less convincing. This comparison may offer lessons for the future study of animal consciousness.

The problem of animal suffering is the atheistic argument that an all-knowing, all-powerful, and all-good God would not use millions of years of animal suffering, disease, and death to form a planet for human beings. This argument has not received as much attention in the philosophical literature as other forms of the problem of evil, yet it has been increasingly touted by atheists since the time of Charles Darwin. While several theists have attempted to provide answers to the problem, they (...) disagree with each other as to which answer is correct. Also, some of these theists have given in to the problem and believe it entails that God is limited in certain ways. B. Kyle Keltz seeks to provide a classical answer to the problem of animal suffering inspired by the medieval philosopher/theologian Thomas Aquinas. In doing so, Keltz not only utilizes the wisdom of Aquinas, but also contemporary insights into non-human animal minds from contemporary philosophy and science. Keltz provides a compelling neo-Thomistic answer to the problem of animal suffering and explains why the classical God of theism would create a world that includes animal death. (shrink)

*Please email me for a copy of the paper if you are interested! -/- Liberal theories of animal consciousness maintain that we should attribute consciousness widely across various species. Conservative theories of animal consciousness maintain that we should not attribute consciousness widely. This paper makes a case for a conservative theory of animal consciousness. The case depends on two defensive moves and one offensive move. The defensive moves indicate that the indistinguishable causal profiles of conscious and non-conscious mental states are (...) not a problem for conservative theories and that intuitions about animal consciousness should not play a role in theory selection. Offensively, I argue that liberal theories of animal consciousness are less parsimonious than conservative theories. The upshot is that liberal theories of animal consciousness are not obviously rationally preferable to conservative theories. (shrink)

Animal welfare scientists face an acute version of the problem of inductive risk, since they must choose whether to affirm attributions of mental states to animals in advisory contexts, knowing their decisions hold consequences for animal welfare. In such contexts, the burden of proof should be sensitive to the consequences of error, but a framework for setting appropriate burdens of proof is lacking. Through reflection on two cases—pain and cognitive enrichment—I arrive at a tentative framework based on the principle of (...) expected welfare maximization. I then discuss the limitations of this framework and the questions it leaves open. (shrink)

While philosophers have been interested in animals since ancient times, in the last few decades the subject of animal minds has emerged as a major topic in philosophy. _The Routledge Handbook of Philosophy of Animal Minds_ is an outstanding reference source to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising nearly fifty chapters by a team of international contributors, the _Handbook_ is divided into eight parts: Mental representation Reasoning and (...) metacognition Consciousness Mindreading Communication Social cognition and culture Association, simplicity, and modeling Ethics. Within these sections central issues, debates and problems are examined, including: whether and how animals represent and reason about the world; how animal cognition differs from human cognition; whether animals are conscious; whether animals represent their own mental states or those of others; how animals communicate; the extent to which animals have cultures; how to choose among competing models and explanations of animal behavior; and whether animals are moral agents and/or moral patients; The Routledge Handbook of Philosophy of Animal Minds is essential reading for students and researchers in philosophy of mind, philosophy of psychology, ethics and related disciplines such as ethology, biology, psychology, linguistics and anthropology.

Review of Michael Tye: Tense bees and shell-shocked crabs: Are animals conscious? New York: Oxford University Press, 2016, 256pp, $29.95 HB.

Barbara King presents grief as the result of the capacity of human and non-human animals for social and affectionate bonds. This is a novel approach that provides a context for interpreting behavioral evidence of grief. The book also offers thought-provoking insights into the relationship between emotion and the expression of emotion. The most surprising element of King’s approach is that, throughout the book, her account of non-human animal grief forces us to reassess the way we treat them.

Phenomenal consciousness or the subjective experience of feeling sensory stimuli is fundamental to human existence. Because of the ubiquity of their subjective experiences, humans seem to readily accept the anthropomorphic extension of these mental states to other animals. Humans will typically extrapolate feelings of pain to animals if they respond physiologically and behaviourally to noxious stimuli. The alternative view that fish instead respond to noxious stimuli reflexly and with a limited behavioural repertoire is defended within the context of our current (...) understanding of the neuroanatomy and neurophysiology of mental states. Consequently, a set of fundamental properties of neural tissue necessary for feeling pain or experiencing affective states in vertebrates is proposed. While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain. (shrink)

Sentience is the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy, comfort and excitement. It is not simply the capacity to feel pain, but feelings of pain, distress or harm, broadly understood, have a special significance for animal welfare law. Drawing on over 300 scientific studies, we evaluate the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid and cuttlefish) and the decapod crustaceans or, (...) for short, decapods (including crabs, lobsters and crayfish). We also evaluate the potential welfare implications of current commercial practices involving these animals. (shrink)
