We discuss the evolutionary transition from animals with limited experiencing to animals with unlimited experiencing and basic consciousness. This transition was, we suggest, intimately linked with the evolution of associative learning and with flexible reward systems based on, and modifiable by, learning. During associative learning, new pathways relating stimuli and effects are formed within a highly integrated and continuously active nervous system. We argue that the memory traces left by such new stimulus-effect relations form dynamic, flexible, and varied global sensory (...) states, which we call categorizing sensory states . These CSSs acquired a function: they came to act as internal “evaluators” and led to positive and negative reinforcement of new behavior. They are therefore the simplest, distinct, first-person motivational states that an animal can have. They constitute what we call basic consciousness, and are the hallmark of animals that can experience. Since associative learning has been found in many invertebrate taxa that first appeared during the Cambrian era, we propose that the processes underlying basic consciousness are phylogenetically ancient, and that their emergence may have fueled the Cambrian explosion.

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)

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)

This editorial introduces the Journal of Consciousness Studies special issue on "Animal Consciousness". The 15 contributors and co-editors answer the question "How should we study animal consciousness scientifically?" in 500 words or fewer.

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.

Simona Ginsburg & Eva Jablonka (G&J), in _The Evolution of the Sensitive Soul (2019)_, explore the nature and status of the mind and subjective experiences from an evolutionary perspective. They raise a fundamental question about ‘the origin of animal consciousness during evolution’ (pg.1). The book begins by tracing the roots of consciousness studies from the Aristotelian perspective on the sensitive soul, referring to the dynamics of the living organization, percepts, and feelings. They use “subjective experiencing” to refer to both (...) sentience and consciousness. They argue that to have an evolutionary account of subjective experiences, we need to develop an understanding of minimal consciousness or a marker like unlimited associative learning (UAL) indicating subjective experiences. In the book, the origin of life is marked by the evolution of goal-directed systems where the system can manifest unlimited heredity. They state that all the questions about the origin of minimal consciousness deal with ‘the emergence of new types of goal-directed systems’ (p.1). (shrink)

The Evolution of the Sensitive Soul is a landmark attempt to make progress on the problem of animal consciousness. Ginsburg and Jablonka propose a general cognitive marker of the presence of consciousness: Unlimited Associative Learning. They use this marker to defend a generous view about the distribution of consciousness in the natural world, on which a capacity for conscious experience is common to all vertebrates, many arthropods and some cephalopod molluscs. They use this inferred distribution to defend a view (...) about the evolution of consciousness, on which it has evolved at least three times, first evolved at around the time of the Cambrian explosion, and was in fact the driving force behind that explosion. In this essay review, I reflect critically on the book’s central idea: the proposal that Unlimited Associative Learning provides a general marker of consciousness. (shrink)

In its January 20th, 2010 decision in Citizens United vs. Federal Election Commission, the United States Supreme Court ruled that certain restrictions on independent expenditures by corporations for political advocacy violate the First Amendment of the Constitution, which provides that “Congress shall make no law […] abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.” Justice Kennedy, writing for the 5-4 majority, (...) held that “[b]y suppressing the speech of manifold corporations, both for-profit and non-profit, the Government prevents their voices and view-points from reaching the public and advising voters on which person or entities are hostile to their interests” (Citizens United vs. Federal Election Commission 558 U.S. 38-9 (2010); emphasis added). Much of the language of the opinion, and some of its reasoning, as this passage illustrates, presupposes that corporations are agents capable of speech, and that it is (at least in part) in the light of this that limitations on political advocacy by corporations are prohibited by the Constitution. -/- While there are other strands in the argument, they are interwoven with the conception of the corporation as agent and speaker, with its voice and its viewpoints. The dissenters on the court objected on precisely this point (among others). Justice Stevens wrote sarcastically in his dissent, joined by Justices Ginsburg, Breyer, and Sotomayor, that “[u]nder the majority’s view, I suppose it may be a First Amendment problem that corporations are not permitted to vote, given that voting is, among other things, a form of speech” (558 U.S. 33 (2010)). Justice Sotomayor suggested in oral argument that the Court’s century-old practice of treating corporations as persons rests on a conceptual mistake. -/- My concern in this essay is not with the question whether the restrictions violate the Constitution. There are many issues that bear on this which will be outside the scope of my discussion. My concern is with the proper conceptual framework for understanding the agency of corporations and corporate speech, and the role that conceptions of these play in the background of the majority’s reasoning. The issue is legal, but it also has philosophical, conceptual and semantic aspects. It will be the latter aspects, and their potential to shed light on legal reasoning, that are my main focus. An adequate framework requires saying what properly speaking the corporation is, how agency is expressed through the corporation, whose agency it is, centrally whether the corporation is an agent or person in its own right, and in what sense it can be said to be capable of speech. I draw on recent work in collective action theory, particularly with respect to the semantics of collective action sentences (Ludwig 2007) and the analysis of the proxy agency in collective action (Ludwig 2014), to show (i) that corporations are neither genuine agents nor (therefore) capable of engaging in genuine speech, (ii) that consequently the First Amendment does not apply to corporations per se, and (iii) that a better understanding of the mechanisms of corporate agency casts doubt on more indirect arguments for extending the First Amendment to “corporate speech” as well.

The only part of the Patient Protection and Affordable Care Act (hereafter, ‘the ACA’) struck down in National Federation of Independent Business (NFIB) et al. v. Sebelius, Secretary of Health and Human Services, et al. was a provision expanding Medicaid. We will argue that this was a mistake; the provision should not have been struck down. We’ll do this by identifying a test that C.J. Roberts used to justify his view that this provision was unconstitutional. We’ll defend that test against (...) some objections raised by J. Ginsburg. We’ll then go on to argue that, properly applied, that test establishes the constitutionality of the Medicaid provision. (shrink)
