We are sympathic with LeDoux’s primary goal here ─ to get a solid scientific grip on what has been dubbed one of the most elusive, important questions in scientific discourse, to identify the underlying biomolecular processes that give rise to consciousness. However, we have issues with the way he goes about it and have tried to present them in a constructive manner. Our commentary is built around our theory of the origins of minds, dubbed the Cellular Basis of Consciousness (CBC), (...) and the empirical research that supports it. The CBC is based on the proposition that life and sentience are co-terminous, that life without subjectivity, feeling, without valenced perception, without the capacity to learn and lay down memories would have been an evolutionary dead-end. It could not have survived in the hostile, chaotic world in flux that dominated our planet four billion years ago. The biological sciences operate on the principle that all species, extant and extinct, evolved from the first prokaryotes. The CBC theory is founded on the principle that all expressions of emotion, perception, and cognition did as well. (shrink)

The commentaries by Ren, de Carvalho, Gabriel, Reber and Baluška raise interesting and timely questions about the views I expressed in The Deep History of Ourselves. I begin my response with an Overview of my perspective, and how it has changed in the three years since publication. This is important since some of the commentators’ concerns may be assuaged by some of these points. Other specific issues raised by each commentator are addressed separately. I greatly appreciate the time and (...) effort they put into their comments on The Deep History of Ourselves. (shrink)

Benardete paradoxes involve a beginningless set each member of which satisfies some predicate just in case no earlier member satisfies it. Such paradoxes have been wielded on behalf of arguments for the impossibility of an infinite past. These arguments often deploy patchwork principles in support of their key linking premise. Here I argue that patchwork principles fail to justify this key premise.

Jules Michelet: Vico and the origins of nationalism -- James Joyce: Vico and the origins of modernism -- Erich Auerbach: Vico and the origins of historism -- Isaiah Berlin: Vico and the origins of pluralism.

We examine two competing solutions to Benardete paradoxes: causal finitism, according to which nothing can have infinitely many causes, and the unsatisfiable pair diagnosis (UPD), according to which such paradoxes are logically impossible and no metaphysical thesis need be adopted to avoid them. We argue that the UPD enjoys notable theoretical advantages over causal finitism. Causal finitists, however, have levelled two main objections to the UPD. First, they urge that the UPD requires positing a ‘mysterious force’ that prevents paradoxes from (...) arising. Since such a force is implausible, the UPD is in trouble. Second, they employ recombination or patchwork principles to argue that paradoxical situations would be possible if causal finitism were false. Since such situations are not possible, causal finitism is true, and so a substantive metaphysical thesis is needed to avoid the paradoxes. We argue that the UPD proponent can successfully respond to these objections. (shrink)

The concept of an operator is used in a variety of practical and theoretical areas. Operators, as both conceptual and physical entities, are found throughout the world as subsystems in nature, the human mind, and the manmade world. Operators, and what they operate, i.e., their substrates, targets, or operands, have a wide variety of forms, functions, and properties. Operators have explicit philosophical significance. On the one hand, they represent important ontological issues of reality. On the other hand, epistemological operators form (...) the basic mechanism of cognition. At the same time, there is no unified theory of the nature and functions of operators. In this work, we elaborate a detailed analysis of operators, which range from the most abstract formal structures and symbols in mathematics and logic to real entities, human and machine, and are responsible for effecting changes at both the individual and collective human levels. Our goal is to find what is common in physical objects called operators and abstract mathematical structures, with the name operator providing foundations for building a unified but flexible theory of operators. The paper concludes with some reflections on functionalism and other philosophical aspects of the ‘operation’ of operators. (shrink)

In this book Joseph Heath brings Jürgen Habermas's theory of communicative action into dialogue with the most sophisticated articulation of the instrumental conception of practical rationality-modern rational choice theory. Heath begins with an overview of Habermas's action theory and his critique of decision and game theory. He then offers an alternative to Habermas's use of speech act theory to explain social order and outlines a multidimensional theory of rational action that includes norm-governed action as a specific type.In the second (...) part of the book Heath discusses the more philosophical dimension of Habermas's conception of practical rationality. He criticizes Habermas's attempt to introduce a universalization principle governing moral discourse, as well as his criteria for distinguishing between moral and ethical problems. Heath offers an alternative account of the level of convergence exhibited by moral argumentation, drawing on game-theoretic models to specify the burden of proof that the theory of communicative action and discourse must assume.

Growing concern has been expressed that we have entered a “post-truth” era in which each of us willfully believes whatever we choose, aided and abetted by alternative and social media that spin alternative realities for boutique consumption. A prime example of the belief in alternative realities is said to be acceptance of “conspiracy theories”—a term that is often used as a pejorative to indict claims of conspiracy that are so obviously absurd that only the unhinged could believe them. The epistemological (...) standard often involved in this indictment, however—the standard of “obvious” falsity—invites subjectivity in its application, because what is obviously false to one person can be common sense to another. This is not just a truism; considerable research suggests that people’s political beliefs, in general, and their acceptance or rejection of conspiracy theories in particular, tends in large part to be determined by partisan, ideological, and other priors.

Longlisted for the PEN/E.O. Wilson Literary Science Writing Award A leading neuroscientist offers a history of the evolution of the brain from unicellular organisms to the complexity of animals and human beings today Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in (...) animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single-cell organisms had to solve the same problems we and our cells have to solve each day. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enhanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

Climate models calibrated exclusively with observations from the 19th through 21st centuries are unsuitable for assessing many important hypotheses about the future. Many systems in the modern climate are expected to cross dynamic thresholds in the near future, requiring more than the instrumental record for adequate calibration. In this paper I argue that paleoclimate analogues from earth’s past can mitigate this threshold problem, even if the modern climate exhibits features that make it historically unique. While this requires that paleoclimatologists be (...) increasingly discriminate in the past systems they target for modern analogues, the upshot is a practice of climate model construction that improves the reliability of future projections. All of this is achieved by integrating features of past climate systems discovered by the study of earth deep in the past. My analysis synthesizes important empirical work done by climate modelers and paleoclimatologists with relevant philosophical work on analogical reasoning in science. (shrink)

In _Pharmaceutical Freedom_ Professor Flanigan argues we ought to grant people self-medication rights for the same reasons we respect people’s right to give (or refuse to give) informed consent to treatment. Despite being the most comprehensive argument in favour of self-medication written to date, Flanigan’s _Pharmaceutical Freedom_ leaves a number of questions unanswered, making it unclear how the safe-guards Flanigan incorporates to protect people from harming themselves would work in practice. In this paper, I extend Professor Flanigan’s account by discussing (...) a hypothetical case to illustrate how these safe-guards could work together to protect people from harms caused by their own ignorance or incompetence.

In this paper we argue that the difference between standard measurement and proxy measurement in paleoclimatology should not be understood in terms of ‘directness’. Measurements taken by climatologists to be paradigmatically non-proxy exhibit the kinds of indirectness that are thought to separate them proxy measurement. Rather, proxy measurements and standard measurements differ in how they account for confounding causal factors. Measurements are ‘proxy’ to the extent that the measurements require vicarious controls, while measurements are not proxy, but rather ‘standard’, to (...) the extent that the measurement apparatus provides sufficient physical control on its own. Guided by this account of proxy measurement, we then consider some of the challenges specific to historical proxy measurement and how it is that historical scientists address these challenges. Historical scientists rely on significant causal dependencies and naturally preserved signals to mitigate the influence of destructive processes over time. (shrink)

The connection between action, reason, and value is explored by examining the connection between reasons and intentions, and between reasons and what we take to be good. This is done in comparison to the classical view, which maintains that valuable aspects of the world constitute reasons for agents. In attempting to explain common features of what it is for people to be rational agents, Raz examines whether there are reasons, which are neutral in values, the explanatory and justificatory role of (...) reasons, the intelligibility of acting for reasons, and the ability to intentionally act in an expressive, yet unreasoned fashion.

John Stuart Mill is one of the hallowed figures of the liberal tradition, revered for his defense of liberal principles and expansive personal liberty. By examining Mill's arguments in On Liberty in light of his other writings, however, Joseph Hamburger reveals a Mill very different from the "saint of rationalism" so central to liberal thought. He shows that Mill, far from being an advocate of a maximum degree of liberty, was an advocate of liberty and control--indeed a degree of (...) control ultimately incompatible with liberal ideals.Hamburger offers this powerful challenge to conventional scholarship by presenting Mill's views on liberty in the context of his ideas about, in particular, religion and historical development. The book draws on the whole range of Mill's philosophical writings and on his correspondence with, among others, Harriet Taylor Mill, Auguste Comte, and Alexander Bain to show that Mill's underlying goal was to replace the traditional religious basis of society with a form of secular religion that would rest on moral authority, individual restraint, and social control. Hamburger argues that Mill was not self-contradictory in thus championing both control and liberty. Rather, liberty and control worked together in Mill's thought as part of a balanced, coherent program of social and moral reform that was neither liberal nor authoritarian.Based on a lifetime's study of nineteenth-century political thought, this clearly written and forcefully argued book is a major reinterpretation of Mill's ideas and intellectual legacy.

For decades the papal tradition has renounced the term ‘war’ as something around which to build an ethical approach. One can sympathize with this: resort to war seems the consequence of ethical failure and brings in its train a host of brutalities including rape, torture, and murder that harm both victims and perpetrators. But that view of ‘war’ is an incomplete representation of the possibilities of the uses of force to secure legitimate political goods. Thus the popes have struggled to (...) maintain a clear voice in the face of abject tragedies like the Russian invasion of Ukraine: on the one hand, Pope Francis condemns war in an almost absolute manner; on the other, he recognizes the legitimacy of Ukrainian defensive uses of force. In so doing, of course, he merely abides the so-called ‘just war theory’ he seems to have discarded. My contribution will focus on the current state of the just war in Catholic teaching. I will maintain the state remains where it has been since at least the middle of the twentieth century: skeptical about the capacity of states to judge in terms of international law, but cognizant of their right to defend themselves against ongoing aggression.

Current theories assume that perception and affect are separate realms of the mind. In contrast, we argue that affect is a genuine online-component of perception instantaneously mirroring the success of different perceptual stages. Consequently, we predicted that the success (failure) of even very early and cognitively encapsulated basic visual Processing steps would trigger immediate positive (negative) affective responses. To test this assumption, simple visual stimuli that either allowed or obstructed early visual processing stages without participants being aware of this were (...) presented briefly. Across 5 experiments, we found more positive affective responses to stimuli that allowed rather than obstructed Gestalt completion at certain early visual stages (Experiments 1–3; briefest presentation 100 ms with post-mask), and visual disambiguation in possible vs. impossible Necker cubes (Experiments 4 and 5; briefest presentation 100 ms with post-mask). This effect was observed both on verbal preference ratings (Experiments 1, 2, and 4) and as facial muscle responses occurring within 2–4 s after stimulus onset (zygomaticus activity; Experiments 3 and 7). For instance, in participants unaware of spatial possibility we found affective discrimination between possible and impossible Necker cubes (the famous Freemish Crate) for 100 ms presentation timings, although a conscious discrimination took more than 2000 ms (Experiment 4).

In this article, the author lists three problems that make any serious discussion about the ethics of leadership a very difficult undertaking. He then proposes a new, postindustrial paradigm of leadership. Using that understanding of leadership, two different sets of ethical analyses of leadership are possible: (I) those concerned with the process of leadership and (2) those concerned with the content of leadership (the changes proposed by the leaders and collaborators). In the end, the author suggests that the industrial paradigm (...) of ethics (the 18th century liberal philosophy) is inadequate to deal with the ethical decision making that leaders and collaborators must do in the 21 st century. Thus, a postindustrial paradigm of ethics must be developed to enable leaders and collaborators to make the tough ethical choices that will be demanded in the new millennium. (shrink)

This paper addresses three factors that have contributed to shifts in decision making in health care. First, the notion of patient autonomy, which has changed due to the rise of patient-centred approaches in contemporary health care and the re-conceptualization of the physician-patient relationship. Second, the understanding of patient autonomy has broadened to better engage patient participation. Third, the need to develop cross-cultural health care ethics. Our paper shows that the shift in the West from the individual to the relational self (...) indicates an important change in the understanding of autonomy through the lens of culture. Practices that recognize the notion of the relational self allow for a more balanced view of autonomy and a richer conception of moral agency. (shrink)

Explaining normativity requires, amongst other things, an examination of the relationship between rationality and reasons and the connection between reasons and principles of reasoning. Essentially, explaining normativity will consist in demonstrating what it is to be a reason and solving related puzzles about reasons. The capability to reason, to justify our reasons for acting, whether we require substantive principles of reason, and the standing of formal reason is considered. The claim that normativity should be defended and justified amounts to a (...) demand for the justification of reason. (shrink)

The relation between reason and the will is explored in reference to the nature of reasons and of normativity. Must we hold beliefs for decisive reasons? Can we be unreflectively motivated by reasons? It is maintained that one need not necessarily be motivated by all the reasons that apply to an agent. Reasons are argued to be optional to the extent that the fact that there are reasons for a certain response make it an eligible response, but not one that (...) is wrong not to adopt. The mediation of the will helps to explain how we are governed by our rationality. (shrink)

A great deal of research has demonstrated that learning is influenced by the learner’s prior background knowledge (e.g. Murphy, 2002; Keil, 1990), but little is known about the processes by which prior knowledge is deployed. We explore the role of explanation in deploying prior knowledge by examining the joint effects of eliciting explanations and providing prior knowledge in a task where each should aid learning. Three hypotheses are considered: that explanation and prior knowledge have independent and additive effects on learning, (...) that their joint effects on learning are subadditive, and that their effects are superadditive. A category learning experiment finds evidence for a superadditive effect: explaining drives the discovery of regularities, while prior knowledge constrains which regularities learners discover. This is consistent with an account of explanation’s effects on learning proposed in Williams & Lombrozo (in press). (shrink)

The question of what distinguishes moral problems from other problems is important to the study of the evolution and functioning of morality. Many researchers concerned with this topic have assumed, either implicitly or explicitly, that all moral problems are problems of cooperation. This assumption offers a response to the moral demarcation problem by identifying a necessary condition of moral problems. Characterizing moral problems as problems of cooperation is a popular response to this issue – especially among researchers empirically studying the (...) beginnings and limits of moral psychology. However, demarcating the moral in this way severely restricts the domain of moral problems. There are plenty of moral problems that aren’t simply problems of cooperation. In this paper I argue that understanding moral problems as problems of cooperation is too restrictive and offer an alternative way of demarcating moral from non-moral problems. Characterizing what makes a problem moral in terms of cooperation excludes a variety of problems that are ordinarily understood and responded to as moral. The alternative characterization that I propose is based on the American Indian/Native American concept of harmony. Using the concept of cooperation to demarcate the moral removes moral agents from their surroundings or contexts by assuming moral agency applies only to humans or other similarly evolved lifeforms. In contrast, using the concept of harmony allows for moral consideration to be granted to non-humans as well (e.g., non-human animals, plant life, ecosystems, etc.). (shrink)
