This paper concerns biopsychism, the position that feeling is a vital activity of all organisms or living beings. It evaluates biopsychism specifically from the perspective of the enactive conception of life and life-mind continuity. Does the enactive conception of life as fundamentally a value-constituting and value-driven process imply a conception of life as sentient of value? Although a plausible case can be made, there remains a conceptual and inferential gap between differential responsiveness to value and hedonic value or affective valence. (...) Nevertheless, the case for zoopsychism—that animals are the only sentient living beings—over biopsychism is also inconclusive. (shrink)

This is a response to the nine commentaries on our target article “Unlimited Associative Learning: A primer and some predictions”. Our responses are organized by theme rather than by author. We present a minimal functional architecture for Unlimited Associative Learning that aims to tie to together the list of capacities presented in the target article. We explain why we discount higher-order thought theories of consciousness. We respond to the criticism that we have overplayed the importance of learning and underplayed the (...) importance of spatial modelling. We decline the invitation to add a negative marker to our proposed positive marker so as to rule out consciousness in plants, but we nonetheless maintain that there is no positive evidence of consciousness in plants. We close by discussing how UAL relates to development and to its material substrate. (shrink)

In this essay, we discuss Simona Ginsburg and Eva Jablonka’s The Evolution of the Sensitive Soul from an interdisciplinary perspective. Constituting perhaps the longest treatise on the evolution of consciousness, Ginsburg and Jablonka unite their expertise in neuroscience and biology to develop a beautifully Darwinian account of the dawning of subjective experience. Though it would be impossible to cover all its content in a short book review, here we provide a critical evaluation of their two key ideas—the role of Unlimited (...) Associative Learning in the evolution of, and detection of, consciousness and a metaphysical claim about consciousness as a mode of being—in a manner that will hopefully overcome some of the initial resistance of potential readers to tackle a book of this length.

Over the past two decades, Ginsburg and Jablonka have developed a novel approach to studying the evolutionary origins of consciousness: the Unlimited Associative Learning framework. The central idea is that there is a distinctive type of learning that can serve as a transition marker for the evolutionary transition from non-conscious to conscious life. The goal of this paper is to stimulate discussion of the framework by providing a primer on its key claims and a clear statement of its main empirical (...) predictions. (shrink)

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile for (...) that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

We welcome Mikhalevich & Powell’s (2020) (M&P) call for a more “‘inclusive”’ animal ethics, but we think their proposed shift toward a moral framework that privileges false positives over false negatives will require radically revising the paradigm assumption in animal research: that there is a clear line to be drawn between sentient beings that are part of our moral community and nonsentient beings that are not.

In this commentary, as philosophers of evolutionary biology, we will consider the evolutionary framework used in the Target Article by: (i) emphasising the fruitfulness of the interdisciplinary approach employed; (ii) highlighting some potentially controversial aspects of the proposal; and finally (iii) outlining some ideas for further integration within the UAL framework. The critical analysis will focus on the relationship between learning and consciousness, on the assumed need for a function for consciousness, and on the type of phylogenetic demarcation introduced by (...) UAL. (shrink)

This commentary on the argument by Jablonka & Ginsburg ( 2022 ) that unlimited associative learning (UAL) provides an evolutionary marker for the transition to consciousness raises the question, “Transition to what?” The proposal that a level of consciousness required for UAL would embody eight specific criteria is credible, but can a limited degree of sentience still exist in animals that lack some of the criteria? The article makes a compelling case that UAL could serve as a marker for the (...) transition to an evolutionarily sustainable level of consciousness, but this may be different from _minimal_ consciousness. Nonetheless, the insight of these authors provides an exemplary roadmap for research on the evolutionary emergence of subjective experience in early animal evolution. (shrink)

O presente artigo se ocupa do problema funcional da consciência referente às questões do porquê a consciência evoluiu e se é relevante para os organismos. A hipótese defendida é que a consciência tem a função comunicativa capaz de recrutar a memória de trabalho, especialmente, os seus subcomponentes especialistas em linguagem, e o sistema cognitivo-computacional, que tem, em seu núcleo, uma estrutura sintática para codificar simbolicamente a informação implícita no organismo. Aos organismos que possuem esses recursos, foi conferida uma vantagem adaptativa, (...) uma vez que tais organismos vivem numa organização socialmente interdependente e, assim, puderam comunicar aos outros organismos, com mais complexidade e precisão do que a comunicação comportamental não simbólica, os seus estados internos e implícitos, tais como o estado dos seus corpos, as suas intenções, os seus planos, e as características do ambiente. A metodologia possui duas fases: primeiro, uma abordagem teórico-conceitual, com base em variados modelos explicativos teórico-experimentais, na qual foram comparadas diferentes definições teórico-conceituais para a origem da consciência. Depois, modelos filogenéticos de estudos comparativos forneceram insights válidos sobre a consciência em animais humanos e não-humanos. Assim, o objetivo geral aqui consiste em postular uma definição conceitual de consciência. Os resultados sugeriram quais as condições necessárias para a emergência da consciência no tocante à memória de trabalho, atenção, representações de alta-ordem e linguagem. Concluiu-se que a pesquisa está em uma fase de brainstorming. Nessa fase, a hipótese é avaliada criticamente e submetida a testes de aproximação com diferentes modelos. Se for bem-sucedida, ela poderá ser aplicada experimentalmente no futuro. (shrink)
