Emotional states of consciousness, or what are typically called emotional feelings, are traditionally viewed as being innately programed in subcortical areas of the brain, and are often treated as different from cognitive states of consciousness, such as those related to the perception of external stimuli. We argue that conscious experiences, regardless of their content, arise from one system in the brain. On this view, what differs in emotional and non-emotional states is the kind of inputs that are processed by a (...) general cortical network of cognition, a network essential for conscious experiences. Although subcortical circuits are not directly responsible for conscious feelings, they provide non-conscious inputs that coalesce with other kinds of neural signals in the cognitive assembly of conscious emotional experiences. In building the case for this proposal, we defend a modified version of what is known as the higher-order theory of consciousness. (shrink)

José Benardete developed a famous paradox involving a beginningless set of items each member of which satisfies some predicate just in case no earlier member satisfies it. The Grim Reaper version of this paradox has recently been employed in favour of various finitist metaphysical theses, ranging from temporal finitism to causal finitism to the discrete nature of time. Here, I examine a new challenge to these finitist arguments—namely, the challenge of implying that the future cannot be endless. In particular, I (...) develop future-oriented Benardete paradoxes and examine their epistemic symmetry with past-oriented paradoxes. (shrink)

Modal collapse arguments are all the rage in certain philosophical circles as of late. The arguments purport to show that classical theism entails the absurdly fatalistic conclusion that everything exists necessarily. My first aim in this paper is bold: to put an end to action-based modal collapse arguments against classical theism. To accomplish this, I first articulate the ‘Simple Modal Collapse Argument’ and then characterize and defend Tomaszewski’s criticism thereof. Second, I critically examine Mullins’ new modal collapse argument formulated in (...) response to the aforementioned criticism. I argue that Mullins’ new argument does not succeed. Third, I critically examine a powers-based modal collapse argument against classical theism that has received much less attention in the literature. Fourth, I show why God’s being purely actual, as well God’s being identical to each of God’s acts, simply cannot entail modal collapse given indeterministic causation. This, I take it, signals the death of modal collapse arguments. But not all hope is lost for proponents of modal collapse arguments—for the death is a fruitful one insofar as it paves the way for new inquiry into at least two new potential problems for classical theism. Showing this is my paper’s second aim. (shrink)

Misconceived Consent: Miguel has stage IV lung cancer. He has nearly exhausted his treatment options when his oncologist, Dr. Llewellyn, tells him about an experimental vaccine trial that may boost his immune response to kill cancer cells. Dr. Llewellyn provides Miguel with a consent form that explains why the study is being conducted, what procedures he will undergo, what the various risks and benefits are, alternative sources of treatment, and so forth. She even sits down with him, carefully talks through (...) the most important points, and gives him time to ask questions. Though it is a Phase 1 study and the chance that he will benefit is very low, Miguel happily agrees to take part. A week later, after the first experimental injection, she asks him if he is worried about the risks. “Risks?” he asks. “I’m sure this is safe—you’re a doctor, after all!”. (shrink)

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)

Various processes are often classified as both deterministic and random or chaotic. The main difficulty in analysing the randomness of such processes is the apparent tension between the notions of randomness and determinism: what type of randomness could exist in a deterministic process? Ergodic theory seems to offer a particularly promising theoretical tool for tackling this problem by positing a hierarchy, the so-called ‘ergodic hierarchy’, which is commonly assumed to provide a hierarchy of increasing degrees of randomness. However, that notion (...) of randomness requires clarification. The mathematical definition of EH does not make explicit appeal to randomness; nor does the usual way of presenting EH involve a specification of the notion of randomness that is supposed to underlie the hierarchy. In this paper we argue that EH is best understood as a hierarchy of random behaviour if randomness is explicated in terms of unpredictability. We then show that, contrary to common wisdom, EH is useful in characterising the behaviour of Hamiltonian dynamical systems. (shrink)

_ Source: _Page Count 28 Recent debates over climate change policy have made it clear that the choice of a social discount rate has enormous consequences for the amount of mitigation that will be recommended. The social discount rate determines how future costs are to be compared to present costs. Philosophers, however, have been almost unanimous in endorsing the view that the only acceptable social rate of time preference is zero, a view that, taken literally, has either absurd or extremely (...) radical implications. The first goal of this paper is to show that the standard arguments against temporal preference are much less persuasive than they are usually taken to be. The second goal is to explore two different avenues of argument that could be adopted, in order to show that temporal discounting of welfare may be permissible. The first involves simply an application of the method of reflective equilibrium, while the second involves consideration of the way that our abstract moral commitments are institutionalized.

ABSTRACT Many recent articles argue that participants who seroconvert during HIV prevention trials deserve treatment when they develop AIDS, and there is a general consensus that the participants in HIV/aids treatment trials should have continuing post‐trial access. As a result, the primary concern of many ethicists and activists has shifted from justifying an obligation to treat trial participants, to working out mechanisms through which treatment could be provided. In this paper I argue that this shift frequently conceals an important assumption: (...) that if there is an obligation to supply treatment, then any party who could provide it may be prevailed upon to discharge the obligation. This assumption is false. The reasons why trial participants should get ART affect who has the duty to provide it. We should not burden governments with the obligations of sponsors, nor researchers with the obligations of the international community. And we should not deprive a group of treatment because their need is less salient than that of research participants. Insisting otherwise may lead to people being wrongfully deprived of access to antiretrovirals. (shrink)

Irregular migrants are morally entitled to a wide range of legal rights, including basic human and civil rights. Therefore, states ought to create a firewall between those charged with protecting and enforcing these rights and those charged with enforcing immigration laws.

I propose to analyze the concept of basing beliefs on reasons. The concept is an important one in understanamg the so-called "inferential" or "indirect" knowledge. After briefly stating the causal analyses of this concept given by D.M. Armstrong and Marshall Swain I will present two cases which show these analyses to be too strong and too weak. Finally, I will propose an analysis which avoids these twin difficulties.

This article explores normative questions about what legal rights settled immigrants should have in liberal democratic states. It argues that liberal democratic justice, properly understood, greatly constrains the distinctions that can be made between citizens and residents. The longer people stay in a society, the stronger their moral claims become, and after a while they pass a threshold that entitles them to virtually the same legal status as citizens and eventually easy access to citizenship itself.

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)

This article considers two competing types of conceptions of the pre-autonomous child’s right to bodily integrity. The first, which I call encroachment conceptions, holds that any physically serious bodily encroachment infringes on the child’s right to bodily integrity. The second, which I call best-interests conceptions, holds that the child’s right to bodily integrity is infringed just in case the child is subjected to a bodily encroachment that substantially deviates from what is in the child’s best interests. I argue in this (...) article that best-interests conceptions are more plausible than encroachment conceptions. They have more attractive implications regarding the permissibility of interventions in children’s bodies that are beneficial for the child but are not medically necessary. They are better able to explain the moral distinction between cases in which an encroachment on a child’s body is needed to benefit that child and cases in which an encroachment on one child’s body is needed to benefit another. Finally, best-interests conceptions are more consonant than encroachment conceptions with our understanding of adults’ right to bodily integrity. (shrink)

Among anthropologists and sociologists, it is widely believed that moral rules are best understood as a type of social norm. Moral philosophers, however, have largely been hostile to this suggestion. In recent years, the impulse to distinguish moral rules from others types of social norm has received what many take to be empirical support from the work of Elliot Turiel and his collaborators, who have argued that there are two distinct “domains” of social cognition, the “moral” and the “conventional.” Many (...) philosophers have taken this as proof that moral rules are fundamentally different from “conventional” social norms. I argue that moral philosophers should not be relying upon Turiel’s view to defend the moral/conventional distinction. First, I show that Turiel is claiming much less than many have taken him to be claiming, because he puts a lot of what philosophers have traditionally thought of as “morality” on the side of convention, or else in the broad region between the two that he refers to as “multidimensional contexts.” Second, I argue that his concept of the “conventional” is so narrow that the overwhelming majority of social norms – such as the standard rules of etiquette – wind up falling into the “multidimensional” category. This stems from his failure to distinguish between genuine conventions and what I refer to as “norms with conventional elements.”. (shrink)

One of the most persistent legacies of Karl Marx and the Young Hegelians has been the centrality of the concept of “ideology” in contemporary social criticism. The concept was introduced in order to account for a very specific phenomenon, viz. the fact that individuals often participate in maintaining and reproducing institutions under which they are oppressed or exploited. In the extreme, these individuals may even actively resist the efforts of anyone who tries to change these institutions on their behalf. Clearly, (...) some explanation needs to be given of how individuals could systematically fail to see where their interests lie, or how they might fail to pursue these interests once these have been made clear to them. This need is often felt with some urgency, since failure to provide such an explanation usually counts as prima facie evidence against the claim that these individuals are genuinely oppressed or exploited in the first place.

This paper examines the need for static dispositions within the basic ontology of the powers view of properties. To lend some focus, Neil Williams’s well developed case for static dispositions is considered. While his arguments are not necessarily intended to address fundamental ontology, they still provide a useful starting point, a springboard for diving into the deeper metaphysical waters of the dispositionalist approach. Within that ontological context, this paper contends that Williams’s arguments fail to establish the need to posit static (...) dispositions, or at least any sort not already well appreciated by advocates of the powers view. The paper then proceeds to suggest an alternative motivation for positing static dispositions, the success of which depends greatly on which ontological approach to objects is paired with the powers view.

Neuron diagrams are heavily employed in academic discussions of causation. Stephen Mumford and Rani Lill Anjum, however, offer an alternative approach employing vector diagrams, which this paper attempts to develop further. I identify three ways in which dispositionalists have taken the activities of powers to be related: stimulation, mutual manifestation, and contribution combination. While Mumford and Anjum do provide resources for representing contribution combination, which might be sufficient for their particular brand of dispositionalism, I argue that those resources are not (...) flexible enough to further accommodate either stimulation or mutual manifestation. Representational tools are provided to address these limitations, improving the general value of the vector model for dispositionalist approaches to causation. (shrink)

In this paper I argue that color is a relational feature of the distal objects of perception, a way of appearing. I begin by outlining three constraints any theory of color should satisfy: (i) physicalism about the non-mental world, (ii) consistency with what is known from color science, and (iii) transparency about color experience. Traditional positions on the ontological status of color, such as physicalist reduction of color to spectral reflectance, subjectivism, dispositionalism, and primitivism, fail, I claim, to meet all (...) three constraints. By treating color as a relational property, a way of appearing, the three constraints can be met. However, serious problems for this view emerge when considering the relation between illusory color experiences (particularly hallucinations) and veridical color experiences. I do not propose a solution to these problems. (shrink)

The primary aim of a theory of consciousness is to articulate existence conditions for conscious states, i.e. the conditions under which a mental state is conscious rather than unconscious. There are two main broad approaches: The Higher-Order approach and the First-Order approach. Higher-Order theories claim that a mental state is conscious only if it is the object of a suitable state of higher-order awareness. First-Order theories reject this necessary condition. However, both sides make the following claim: for any mental state (...) M of a subject S, M is conscious if there is something it is like for S to be in M. This is the Nagelian Conception of consciousness. Taking the Nagelian Conception as a starting point, I contend that the best rationalizing explanation for the ways in which Higher-Order and First-Order theorists contribute to their dispute is to see those contributions as consistent responses to two distinct questions.

In his recent paper ‘Knowing What Things Look Like’, Matthew McGrath offers a challenge to the idea that knowing an object by seeing it, ‘visual objectual knowledge’ is an instance of immediate knowledge. I offer supporters of the notion of immediate visual objectual knowledge two potential strategies for blocking McGrath’s argument: either by questioning McGrath’s claim about the role that knowing what an object looks like plays in visual objectual knowledge or by denying that any explanation of how knowing what (...) an object looks like plays that role must proceed through an appeal to factual knowledge involving that object’s looks.

LetCbe an axiom system formalized within the first order functional calculus, and letC′ be related toCas the Bernays-Gödel set theory is related to the Zermelo-Fraenkel set theory.

Mostowski has also proved the stronger result that any theorem ofC′ which can be formalized inCis a theorem ofC.The proofs of Novak and Mostowski do not provide a direct method for obtaining a contradiction inCfrom a contradiction inC′. We could, (...) of course, obtain such a contradiction by proving the theorems ofCone by one; the above result assures us that we must eventually obtain a contradiction. A similar process is necessary to obtain the proof of a theorem inCfrom its proof inC′. The purpose of this paper is to give a new proof of these theorems which provides a direct method of obtaining the desired contradiction or proof.The advantage of the proof may be stated more specifically by arithmetizing the syntax ofCandC′.

Memory blunting is a pharmacological intervention that decreases the emotional salience of memories. The technique promises a brighter future for those suffering from memory-related disorders such as PTSD, but it also raises normative questions about the limits of its permissibility. So far, neuroethicists have staked out two primary camps in response to these questions. In this paper, I argue both are problematic. I then argue for an alternative approach to memory blunting, one that can accommodate the considerations that motivate rival (...) approaches even while avoiding the problems these rivals face. In addition to arguing for this primary thesis, the paper also aims to suggest something about neuroethics generally: despite what some neuroethicists claim, new discoveries in neuroscience may not typically upend traditional views of morality. Rather, discoveries in neuroscience often provide us with new occasions to reflect on enduring questions about what it means to be human. (shrink)

We call A weakly low for K if there is a c such that $K^A(\sigma)\geq K(\sigma)-c$ for infinitely many σ; in other words, there are infinitely many strings that A does not help compress. We prove that A is weakly low for K if and only if Chaitin's Ω is A-random. This has consequences in the K-degrees and the low for K (i.e., low for random) degrees. Furthermore, we prove that the initial segment prefix-free complexity of 2-random reals is infinitely (...) often maximal. This had previously been proved for plain Kolmogorov complexity. (shrink)

This article introduces an intuitive conservation dilemma called the Canyon Dilemma: Is it possible to condemn the mining of the Grand Canyon, even by a poor generation, while also permitting this generation’s mining of an unremarkable small canyon? It then argues that not one of several prominent theories of environmental justice, including various forms of egalitarianism, welfarism, deep-ecological theories, communitarianism and free-market environmentalism, can navigate this dilemma. The article concludes by highlighting the dilemma-navigating potential of the equal-claims idea – the (...) idea that the natural world is something to which every human being, present and future, has an equal, substantive claim.

Intra-molecular connectivity (that is, chemical structure) does not emerge from computations based on fundamental quantum-mechanical principles. In order to compute molecular electronic energies (of C 3 H 4 hydrocarbons, for instance) quantum chemists must insert intra-molecular connectivity “by hand.” Some take this as an indication that chemistry cannot be reduced to physics: others consider it as evidence that quantum chemistry needs new logical foundations. Such discussions are generally synchronic rather than diachronic —that is, they neglect ‘historical’ aspects. However, systems of (...) interest to chemists generally are metastable . In many cases chemical systems of a given elemental composition may exist in any one of several different metastable states depending on the history of the system. Molecular structure generally depends on contingent historical circumstances of synthesis and separation, rather than solely or mainly on relative energies of alternative stable states, those energies in turn determined by relationships among components. Chemical structure is usually ‘kinetically-determined’ rather than ‘thermodynamically-determined.’ For instance, cyclical hydrocarbon ring-systems (as in cyclopropene) are produced only in special circumstances. Adequate theoretical treatments must take account of the persistent effects of such contingent historical events whenever they are relevant—as they generally are in chemistry. (shrink)

THE word “ Organicism,” although it may seem unfamiliar to the younger generation of biologists, is not a new one, and has been heard of already in that shadowy limbo where philosophical and biological conceptions meet on common ground. The genius of its original minting is not known, but it figured largely in the great work of Yves Delage, the French zoologist, in which he attempted to survey and criticize every important biological theory which had ever been seriously produced. Hisl'Hérédité (...) et les grands Problèmes de la Biologie appeared in 1903, and in it he classified all biological theories, past, present, and future, under the four heads of. (shrink)

This article considers whether any interpretation of the idea of equal claims to the natural world can resolve the Canyon Dilemma (i.e. can justify protecting the Grand Canyon but not a small canyon from mining by a poor generation).

It then demonstrates that a pluralist theory of environmental justice committed to both respect for the separateness of persons and to the collective good (...) can justify a type of intergenerational non-absolute equal division of natural resource rights that can navigate the Canyon Dilemma.

I explore the implications of recognizing two forms of access that might be constitutively related to phenomenal consciousness.

In recent years, there has been growing awareness among evolutionary ethicists that systems of cooperation based upon “weak” reciprocity mechanisms lack scalability, and are therefore inadequate to explain human ultrasociality. This has produced a shift toward models that strengthen the cooperative mechanism, by adding various forms of commitment or punishment. Unfortunately, the most prominent versions of this hypothesis wind up positing a discredited mechanism as the basis of human ultrasociality, viz. a “greenbeard.” This paper begins by explaining what a greenbeard (...) is, and why evolutionary theorists are doubtful that such a mechanism could play a significant role in explaining human prosociality. It goes on to analyze several recent philosophical works in evolutionary ethics, in order to show how the suggestion that morality acts as a commitment device tacitly relies upon a greenbeard mechanism to explain human cooperation. It concludes by showing how some early scientific models in the “evolution of cooperation” literature, which introduced punishment as a device to enhance cooperation, also tacitly relied upon a greenbeard mechanism.
