In humans, conscious perception and cognition depends upon the thalamocortical complex, which supports perception, explicit cognition, memory, language, planning, and strategic control. When parts of the T-C system are damaged or stimulated, corresponding effects are found on conscious contents and state, as assessed by reliable reports. In contrast, large regions like cerebellum and basal ganglia can be damaged without affecting conscious cognition directly. Functional brain recordings also show robust activity differences in cortex between experimentally matched conscious and unconscious events. This (...) basic anatomy and physiology is highly conserved in mammals and perhaps ancestral reptiles. While language is absent in other species, homologies in perception, memory, and motor cortex suggest that consciousness of one kind or another may be biologically fundamental and phylogenetically ancient. In humans we infer subjective experiences from behavioral and brain evidence. This evidence is quite similar in other mammals and perhaps some non-mammalian species. On the weight of the biological evidence, therefore, subjectivity may be conserved in species with human-like brains and behavior. (shrink)

My claim that Skinner believed in psychological atoms is actually strengthened by Baars' remark that Skinner 's behaviorist atoms could take a variety of physical forms. Baars is correct that Pavlov, unlike Skinner, thought that psychological atoms were identical to certain physiological items. But Skinner, as a non-reductive atomist, thought he could permit his psychological atoms to have a variety of physical forms. He still believed that even though each S-R connection was not really physical, it could nevertheless (...) be understood as being independent of all other S-R connections,and without reference to the laws of physics. It doesn't really make sense to speak of something as being both ontologically determined by its function, and ontologically independent, but philosophical clarity was not Skinner 's strong point.

Baars’ Global Workspace theory suggests that consciousness functions as a gateway, facilitating focused access to any part of the brain. While this hypothesis does not address the ‘hard problems’, namely, the very nature of consciousness, it constrains any theory that attempts to do so and provides important insights into the relation between consciousness and cognition. Many questions have found new answers once they were turned upside down. In medicine, for example, important discoveries have been made when, instead of asking (...) ‘Why did this disease inflict this person now?’ someone rather asked ‘Why doesn't this disease always inflict all people?’ Bernard Baars tries to do something similar with the mind-body problem. Whereas most people often ask, ‘Why are there conscious experiences accompanying some brain processes?’, he asks, ‘Why aren't there conscious experiences accompanying all brain processes?’. (shrink)

T. A. Cavanaugh's Hippocrates' Oath and Asclepius' Snake: The Birth of the Medical Profession articulates the Oath as establishing the medical profession's unique internal medical ethic - in its most basic and least controvertible form, this ethic mandates that physicians help and not harm the sick. Relying on Greek myth, drama, and medical experience (e.g., homeopathy), the book shows how this medical ethic arose from reflection on the most vexing medical-ethical problem -- injury caused by a physician -- and argues (...) that deliberate iatrogenic harm, especially the harm of a doctor choosing to kill (physician assisted suicide, euthanasia, abortion, and involvement in capital punishment), amounts to an abandonment of medicine as an exclusively therapeutic profession. The book argues that medicine as a profession necessarily involves stating before others what one stands for: the good one seeks and the bad one seeks to avoid on behalf of the sick, and rejects the view that medicine is purely a technique lacking its own unique internal ethic. It concludes noting that medical promising (as found in the White Coat Ceremony through which U. S. medical students matriculate) implicates medical autonomy which in turn merits respect, including honoring professional conscientious objections. (shrink)

_Self-Reflection for the Opaque Mind_ attempts to solve a grave problem about critical self-reflection. Psychological studies indicate not just that we are bad at detecting our own "ego-threatening" thoughts; they also suggest that we are ignorant of even our ordinary thoughts. However, self-reflection presupposes an ability to know one’s own thoughts. So if ignorance is the norm, why attempt self-reflection? While admitting the psychological data, this book argues that we are infallible in a limited range of self-discerning judgments—that in some (...) cases, these judgments are self-fulfilling or self-verifying. Even so, infallibility does not imply indubitability, and the author does not wish to provide a "foundation" for empirical knowledge. The point is rather to explain how self-reflection as a rational activity is possible. The book will be of interest to scholars working on the issue of self-reflection across a wide range of disciplines, including philosophy, psychology, and cognitive science. (shrink)

The problem of animal consciousness has profound implications on our concept of nature and of our place in the natural world. In philosophy of mind and cognitive neuroscience the problem of animal consciousness raises two main questions (Velmans, 2007): the distribution question (“are there conscious animals beside humans?”) and the phenomenological question (“what is it like to be a non-human animal?”). In order to answer these questions, many approaches take into account similarities and dissimilarities in animal and human behavior, e.g. (...) the use of language or tools and mirror self-recognition (Allen and Bekoff, 2007), however behavioral arguments don’t seem to be conclusive (Baars, 2005). Cognitive neuroscience is providing comparative data on structural and functional similarities, respectively called “homologies” and “analogies”. Many experimental results suggest that the thalamocortical system is essential for consciousness (Edelman and Tononi, 2000; Tononi, 2008). The argument from homology states that the general structure of thalamocortical system remained the same in the last 100-200 million years, for it is neuroanatomically similar in all the present and past mammals and it didn’t change much during phylogeny (Allen and Bekoff, 2007). The argument from analogy states that the key functional processes correlated with consciousness in humans are still present in all other mammals and many other animals (Baars, 2005). These processes are information integration through effective cortical connectivity (Massimini et al., 2005; Rosanova et al., 2012) and elaboration of information at a global level (Dehaene and Changeux, 2011). On this basis, the Cambridge Declaration on Consciousness states that all mammals, birds, and many other animals (such as octopuses) possess the neurological substrates of consciousness (Low et al., 2012). Conscious experience is private (Chalmers, 1995; Nagel, 1974) therefore the answer to the phenomenological question may be impossible. Nevertheless, cognitive neuroscience may provide an answer to the distribution question, showing that conscious experience is not limited to humans since it is a major biological adaptation going back millions of years.

J. Willard Gibbs derived the following equation to quantify the maximum work possible for a chemical reaction$${\text{Maximum work }} = \, - \Delta {\text{G}}_{{{\text{rxn}}}} = \, - \left( {\Delta {\text{H}}_{{{\text{rxn}}}} {-}{\text{ T}}\Delta {\text{S}}_{{{\text{rxn}}}} } \right) {\text{ constant T}},{\text{P}}$$ Maximum work = - Δ G rxn = - Δ H rxn - T Δ S rxn constant T, P ∆Hrxn is the enthalpy change of reaction as measured in a reaction calorimeter and ∆Grxn the change in Gibbs energy as measured, if (...) feasible, in an electrochemical cell by the voltage across the two half-cells. To Gibbs, reaction spontaneity corresponds to negative values of ∆Grxn. But what is T∆Srxn, absolute temperature times the change in entropy? Gibbs stated that this term quantifies the heating/cooling required to maintain constant temperature in an electrochemical cell. Seeking a deeper explanation than this, one involving the behaviors of atoms and molecules that cause these thermodynamic phenomena, I employed an “atoms first” approach to decipher the physical underpinning of T∆Srxn and, in so doing, developed the hypothesis that this term quantifies the change in “structural energy” of the system during a chemical reaction. This hypothesis now challenges me to similarly explain the physical underpinning of the Gibbs–Helmholtz equation$${\text{d}}\left( {\Delta {\text{G}}_{{{\text{rxn}}}} } \right)/{\text{dT}} = - \Delta {\text{S}}_{{{\text{rxn}}}} \left( {\text{constant P}} \right)$$ d Δ G rxn / dT = - Δ S rxn constant P While this equation illustrates a relationship between ∆Grxn and ∆Srxn, I don’t understand how this is so, especially since orbital electron energies that I hypothesize are responsible for ∆Grxn are not directly involved in the entropy determination of atoms and molecules that are responsible for ∆Srxn. I write this paper to both share my progress and also to seek help from any who can clarify this for me. (shrink)

ABSTRACTRational agents have consistent beliefs. Bayesianism is a theory of consistency for partial belief states. Rational agents also respond appropriately to experience. Dogmatism is a theory of how to respond appropriately to experience. Hence, Dogmatism and Bayesianism are theories of two very different aspects of rationality. It's surprising, then, that in recent years it has become common to claim that Dogmatism and Bayesianism are jointly inconsistent: how can two independently consistent theories with distinct subject matter be jointly inconsistent? In this (...) essay I argue that Bayesianism and Dogmatism are inconsistent only with the addition of a specific hypothesis about how the appropriate responses to perceptual experience are to be incorporated into the formal models of the Bayesian. That hypothesis isn't essential either to Bayesianism or to Dogmatism, and so Bayesianism and Dogmatism are jointly consistent. That leaves the matter of how experiences and credences are related, a... (shrink)

How do we judge whether an action is morally right or wrong? If an action is wrong, what reason does that give us not to do it? Why should we give such reasons priority over our other concerns and values? In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other. According to his contractualist view, thinking about right and wrong is thinking (...) about what we do in terms that could be justified to others and that they could not reasonably reject. He shows how the special authority of conclusions about right and wrong arises from the value of being related to others in this way, and he shows how familiar moral ideas such as fairness and responsibility can be understood through their role in this process of mutual justification and criticism. Scanlon bases his contractualism on a broader account of reasons, value, and individual well-being that challenges standard views about these crucial notions. He argues that desires do not provide us with reasons, that states of affairs are not the primary bearers of value, and that well-being is not as important for rational decision-making as it is commonly held to be. Scanlon is a pluralist about both moral and non-moral values. He argues that, taking this plurality of values into account, contractualism allows for most of the variability in moral requirements that relativists have claimed, while still accounting for the full force of our judgments of right and wrong.

This is a condensed description of the contents and overarching argument found in Hippocrates’ Oath and Asclepius’ Snake: The Birth of the Medical Profession. In that work, I maintain that the basic medical ethical problem concerns iatrogenic harm. I focus particularly on what I refer to as ‘role-conflation’. This most egregious form of iatrogenic harm occurs when a physician deliberately adopts the role of wounder. A contemporary practice such as physician-assisted suicide exemplifies a doctor’s deliberate wounding. I argue that the (...) author of the Hippocratic Oath – aware of the chronic risk of role-conflation – responds to this threat by having the oath-taker specifically forswear signal acts that wound the sick, such as giving a deadly drug even if asked, giving an abortifacient, sexual predation, and gossiping. I argue that by means of the Oath, Hippocrates founds medicine as a profession, a practice intimately involving promising. (shrink)

The most pressing issues of the twenty-first century—climate change and persistent hunger in a world of food surpluses, to name only two—are not problems that can be solved from within individual disciplines, nation-states, or cultural perspectives. They are predicaments that can only be resolved by generating sustained and globally robust coordination across value systems. The scale of the problems and necessity for coordinated global solutions signal a world historical transit as momentous as the Industrial Revolution: a transition from the predominance (...) of technical knowledge to that of ethical deliberation. This volume brings together leading thinkers from around the world to deliberate on how best to correlate worth (value) with what is worthwhile (values), pairing human prosperity with personal, environmental, and spiritual flourishing in a world of differing visions of what constitutes a moral life. Especially in the aftermath of what is now being called the Great Recession, awareness has mounted of the imperative to question the modern divorce of economics from ethics. While the domains of economics and ethics were from antiquity through at least the eighteenth century understood in many cultures to be coterminous and mutually entailing, the modern assumption has been that the goal of maximizing human prosperity and the aim of justly enhancing our lives as persons and as communities were functionally and practically distinct. Working from a wide array of perspectives, the contributors to this volume offer a set of challenges to the assumed independence of the quantitative and qualitative dimensions of human and planetary well-being. Reflecting on the complex interrelationship among economics, justice, and equity, the book resists "one size fits all" approaches and struggles to revitalize the marriage of economics and ethics by activating cultural differences as the basis of mutual contribution to shared human flourishing. The publication of this important collection will stimulate or extend critical debates among scholars and students working in a number of disciplines in the social sciences and humanities, including philosophy, history, environmental studies, economics, and law.

This is the introduction to the Routledge Companion to Thought Experiments.

It is clearly impermissible to kill one person because his organs can be used to save five others who are in need of transplants. It has seemed to many that the explanation for this lies in the fact that in such cases we would be intending the death of the person whom we killed, or failed to save. What makes these actions impermissible, however, is not the agent's intention but rather the fact that the benefit envisaged does not justify an (...) exception to the prohibition against killing or the requirement to give aid. The difference between this explanation and one appealing to intention is easily overlooked if one fails to distinguish between the prospective use of a moral principle to guide action and its retrospective use to appraise the way an agent governed him or herself. Even if this explanation is accepted, however, it remains an open question whether and how an agent's intention may be relevant to the permissibility of actions in other cases. \\\ [Jonathan Dancy] My first four sections concentrate on the second section of Professor Scanlon's contribution, where he lays out his conception of moral principles and of the role they play in theory and practice. I will raise questions on the following issues: 1. Scanlon's initial introduction of the notion of a principle. 2. His rejection of the standard view that principles are concerned with the forbidding, permitting and requiring of actions. 3. His rejection of pro tanto conceptions of principles in favour of a conception of them as conclusive. 4. The resulting account of what it is for a principle to face and survive exceptions. Scanlon's discussion of these matters here both appeals to and is in some respects more detailed than the relevant section of his recent What We Owe to Each Other. The topic is interesting both for the role played by principles in Scanlon's present discussion of intention and permissibility, and more generally because of his account of wrongness: an act is wrong iff it is ruled out by principles that nobody could reasonably reject. The remainder of my contribution is concerned with the ostensible focus of IP, namely the relevance of agent-intentions to the permissibility of what is done. (shrink)

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

Kit Fine (2000) breaks with tradition, arguing that, pace Russell (e.g., 1903: 228), relations have neither directions nor converses. He considers two ways to conceive of these new "neutral" relations, positionalism and anti-positionalism, and argues that the latter should be preferred to the former. Cody Gilmore (2013) argues for a generalization of positionalism, slot theory, the view that a property or relation is n-adic if and only if there are exactly n slots in it, and (very roughly) that each slot (...) may be occupied by at most one entity. Slot theory (and with it, positionalism) bears the full brunt of Fine's (2000) symmetric completions and conflicting adicities problems. I fully develop an alternative, plural slot theory (or pocket theory), which avoids these problems, key elements of which are first considered by Yi (1999: 168 ff.). Like the slot theorist, the pocket theorist posits entities (pockets) in properties and relations that can be occupied. But unlike the slot theorist, the pocket theorist denies that at most one entity can occupy any one of them. As a result, she must also deny that the adicity of a property or relation is equal to the number of occupiable entities in it. By abandoning these theses, however, the pocket theorist is able to avoid Fine's problems, resulting in a stronger theory about the internal structure of properties and relations. Pocket theory also avoids a serious drawback of anti-positionalism. (shrink)

What is the highest good actually good for in Kant’s third Critique? While there are well-worked out answers to this question in the literature that focus on the highest good’s practical importance, this paper argues that there is an important function for the highest good that has to do exclusively with contemplation. This important function becomes clear once one notices that coherent [konsequent] thinking, for Kant, was synonymous with "bündiges" thinking, and that both are connected with the highest good in (...) the third Critique’s moral proof for God’s existence. I show that the original meaning of "bündig," which is from the carpentry trade and has been forgotten, illuminates the stakes of the highest good in Kant’s system. For us, as proverbial carpenters of reason, coherence is essential for the intellectual activity of constructing a philosophical worldview in his transcendental idealism. I motivate the reading further by showing how this function can neatly reconstruct Kant’s proof for God’s existence in the third Critique. I conclude by sketching Kant’s reasons for why the project of creating a coherent worldview grounded in the highest good is worth the labor costs. (shrink)

The purpose of this paper is to advance understanding of intellectually virtuous honesty, by examining the relationship between a recent account of intellectual honesty and a recent account of intellectual transparency. The account of intellectual honesty comes from Nathan King, who adapts the work of Christian Miller on moral honesty, while the account of intellectual transparency comes from T. Ryan Byerly. After introducing the respective accounts, I identify four potential differences between intellectual honesty and intellectual transparency as understood by these (...) accounts. I then turn to the question of how to think about the relationship between these traits in light of these potential differences. I make the case that intellectual transparency can either be regarded as an exceptionally strong or ideal variety of intellectual honesty, or it can be regarded as a distinct virtue from intellectual honesty which is a more cardinal virtue than the latter. Along the way, I also note some places where a case can be made that Miller's and King's accounts of honesty and intellectual honesty are in need of refinement or clarification. (shrink)

Fine and Antonelli introduce two generalizations of permutation invariance — internal invariance and simple/double invariance respectively. After sketching reasons why a solution to the Bad Company problem might require that abstraction principles be invariant in one or both senses, I identify the most fine-grained abstraction principle that is invariant in each sense. Hume’s Principle is the most fine-grained abstraction principle invariant in both senses. I conclude by suggesting that this partially explains the success of Hume’s Principle, and the comparative lack (...) of success in reconstructing areas of mathematics other than arithmetic based on non-invariant abstraction principles.

The variety DMM of De Morgan monoids has just four minimal subvarieties. The join-irreducible covers of these atoms in the subvariety lattice of DMM are investigated. One of the two atoms consisting of idempotent algebras has no such cover; the other has just one. The remaining two atoms lack nontrivial idempotent members. They are generated, respectively, by 4-element De Morgan monoids C4 and D4, where C4 is the only nontrivial 0-generated algebra onto which finitely subdirectly irreducible De Morgan monoids may (...) be mapped by noninjective homomorphisms. The homomorphic preimages of C4 within DMM constitute a proper quasivariety, which is shown to have a largest subvariety U. The covers of the variety within U are revealed here. There are just ten of them. In exactly six of these ten varieties, all nontrivial members have C4 as a retract. In the varietal join of those six classes, every subquasivariety is a variety—in fact, every finite subdirectly irreducible algebra is projective. Beyond U, all covers of [or of ] within DMM are discriminator varieties. Of these, we identify infinitely many that are finitely generated, and some that are not. We also prove that there are just 68 minimal quasivarieties of De Morgan monoids. (shrink)

The study of conscious experience has seen remarkable strides in the last ten years, reflecting important technological breakthroughs and the enormous efforts of researchers in disciplines as varied as neuroscience, cognitive science, and philosophy. Although still embroiled in debate, scientists are now beginning to find common ground in their understanding of consciousness, which may pave the way for a unified explanation of how and why we experience and understand the world around us. Written by eminent psychologist Bernard J. Baars, (...) In the Theater of Consciousness: The Workspace of the Mind brings us to the frontlines of this exciting discipline, offering the general reader a fascinating overview of how top scientists currently understand the processes underlying conscious experience. Combining psychology with brain science, Baars brilliantly brings his subject to life with a metaphor that has been used to understand consciousness since the time of Aristotle--the mind as theater. Here consciousness is seen as a "stage" on which our sensations, perceptions, thoughts, and feelings play to a vast, silent audience. Behind the scenes, silent context operators shape conscious experience; they include implicit expectations, self systems, and scene setters. Using this framework, Baars presents compelling evidence that human consciousness rides on top of biologically ancient mechanisms. In humans it manifests itself in inner speech, imagery, perception, and voluntary control of thought and action. Topics like hypnosis, absorbed states of mind, adaptation to trauma, and the human propensity to project expectations on uncertainty, all fit into the expanded theater metaphor. As Baars explores our present understanding of the mind, he takes us to the top laboratories around the world, where we witness some of the field's most exciting breakthroughs and discoveries. And throughout the book, Baars has sprinkled numerous and often highly amusing on-the-spot demonstrations that illuminate the ideas under discussion. Understanding consciousness is perhaps the most difficult puzzle facing the sciences today. In the Theater of Consciousness offers an invaluable introduction to the field, brilliantly weaving together the various theories that have emerged as scientists continue their quest to uncover the profound mysteries of the mind--and of human nature itself.
