This first volume contains discussions of the brain, methods for analyzing behavior, thought, consciousness, attention, association, time, and memory.

Many everyday actions have major but unforeseeable long-term consequences. Some argue that this fact poses a serious problem for consequentialist moral theories. We argue that the problem for non-consequentialists is greater still. Standard non-consequentialist constraints on doing harm combined with the long-run impacts of everyday actions entail, absurdly, that we should try to do as little as possible. We call this the Paralysis Argument. After laying out the argument, we consider and respond to a number of objections. We then suggest (...) what we believe is the most promising response: to accept, in practice, a highly demanding morality of beneficence with a long-term focus. (shrink)

Darwin's greatest accomplishment was to show how life might be explained as the result of natural selection. But does Darwin's theory mean that life was unintended? William A. Dembski argues that it does not. In this book Dembski extends his theory of intelligent design. Building on his earlier work in The Design Inference (Cambridge, 1998), he defends that life must be the product of intelligent design. Critics of Dembski's work have argued that evolutionary algorithms show that life can be (...) explained apart from intelligence. But by employing powerful recent results from the No Free Lunch Theory, Dembski addresses and decisively refutes such claims. As the leading proponent of intelligent design, Dembski reveals a designer capable of originating the complexity and specificity found throughout the cosmos. Scientists and theologians alike will find this book of interest as it brings the question of creation firmly into the realm of scientific debate. (shrink)

Récurrente sous différentes formes dans le domaine de la lexicométrie, l’analyse cooccurrentielle vise à dévoiler les attractions lexicales qui opèrent dans un texte en restituant un état intermédiaire entre la séquence textuelle et l’inventaire lexical, état qui doit combiner l’explicitation syntagmatique de l’une avec la hiérarchisation statistique de l’autre. Pour dépasser les résultats des méthodes de cooccurrence classiques et identifier des systèmes cooccurrentiels plus complexes à l’oeuvre dans le texte, il s’avère nécessaire de substituer à l’approche analytique des associations lexicales (...) une vue synthétique de ces attractions prééminentes en contexte.

The war against war is going to be no holiday excursion or camping party. The military feelings are too deeply grounded to abdicate their place among our ideals until better substitutes are offered than the glory and shame that come to nations as well as to individuals from the ups and downs of politics and the vicissitudes of trade. There is something highly paradoxical in the modern man's relation to war. Ask all our millions, north and south, whether they would (...) vote now (were such a thing possible) to have our war for the Union expunged from history, and the record of a peaceful transition to the present time substituted for that of its marches and battles, and probably hardly a handful of eccentrics would say yes. Those ancestors, those efforts, those memories and legends, are the most ideal part of what we now own together, a sacred spiritual possession worth more than all the blood poured out. Yet ask those same people whether they would be willing, in cold blood, to start another civil war now to gain another similar possession, and not one man or woman would vote for the proposition. In modern eyes, precious though wars may be they must not be waged solely for the sake of the ideal harvest. Only when forced upon one, is a war now thought permissible. -/- It was not thus in ancient times. The earlier men were hunting men, and to hunt a neighboring tribe, kill the males, loot the village and possess the females, was the most profitable, as well as the most exciting, way of living. Thus were the more martial tribes selected, and in chiefs and peoples a pure pugnacity and love of glory came to mingle with the more fundamental appetite for plunder. (shrink)

Discourse ethics represents an exciting new development in neo-Kantian moral theory. William Rehg offers an insightful introduction to its complex theorization by its major proponent, Jürgen Habermas, and demonstrates how discourse ethics allows one to overcome the principal criticisms that have been leveled against neo-Kantianism. Addressing both "commun-itarian" critics who argue that universalist conceptions of justice sever moral deliberation from community traditions, and feminist advocates of the "ethics of care" who stress the moral significance of caring for other individuals, (...) Rehg shows that discourse ethics combines impartiality with solidarity. He provides the first systematic reconstruction of Habermas's theory and explores its relationship to the work of such contemporary philosophers as Charles Taylor. His book articulates a bold alternative to the split between the "right" and the "good" in moral theory and will greatly interest philosophers, social and legal scholars, and political theorists.

William James gets very high on nitrous oxide and then writes about it.

In many domains of biology, explanation takes the form of characterizing the mechanism responsible for a particular phenomenon in a specific biological system. How are such explanations generalized? One important strategy assumes conservation of mechanisms through evolutionary descent. But conservation is seldom complete. In the case discussed, the central mechanism for circadian rhythms in animals was first identified in Drosophila and then extended to mammals. Scientists' working assumption that the clock mechanisms would be conserved both yielded important generalizations and served (...) as a heuristic for discovery, especially when significant differences between the insect and mammalian mechanism were identified. †To contact the author, please write to: Department of Philosophy and Interdisciplinary Programs in Science Studies and Cognitive Science, 0119, University of California, San Diego, La Jolla, CA 92093‐0119; e‐mail: [email protected].

It is worthwhile to search for forms of coding, processing, and learning common to various cortical regions and cognitive functions. Local cortical processors may coordinate their activity by maximizing the transmission of information coherently related to the context in which it occurs, thus forming synchronized population codes. This coordination involves contextual field (CF) connections that link processors within and between cortical regions. The effects of CF connections are distinguished from those mediating receptive field (RF) input; it is shown how CFs (...) can guide both learning and processing without becoming confused with the transmission of RF information. Simulations explore the capabilities of networks built from local processors with both RF and CF connections. Physiological evidence for synchronization, CFs, and plasticity of the RF and CF connections is described. Coordination via CFs is related to perceptual grouping, the effects of context on contrast sensitivity, amblyopia, implicit influences of color in achromotopsia, object and word perception, and the discovery of distal environmental variables and their interactions through self-organization. Cortical computation could thus involve the flexible evaluation of relations between input signals by locally specialized but adaptive processors whose activity is dynamically associated and coordinated within and between regions through specialized contextual connections. Key Words: cell assemblies; cerebral cortex; context; coordination; dynamic binding; epistemology; functional specialization; learning; neural coding; neural computation; neuropsychology; object recognition; perception; reading; self-organization; synaptic plasticity; synchronization.

Second, there is a form of ampliative inference that has come to be called ‘inference to the best explanation,’ or more briefly ‘explanatory inference.’ Roughly: From the fact that a certain hypothesis would explain the data at hand better than any other available hypothesis, we infer with some degree of confidence that that leading hypothesis is correct. There is no question but that this inference is often performed. Arguably, every human being performs it many times in a day, perhaps without (...) letup. (shrink)

In the opening to his late essay, Der Gedanke, Frege asserts without qualification that the word "true" points the way for logic. But in a short piece from his Nachlass entitled "My Basic Logical Insights", Frege writes that the word true makes an unsuccessful attempt to point to the essence of logic, asserting instead that "what really pertains to logic lies not in the word "true" but in the assertoric force with which the sentence is uttered". Properly understanding what Frege (...) takes to be at issue here is crucial for understanding his conception of logic and, in particular, what he takes to be its normative status vis-à-vis judgement, assertion, and inference. In this paper, I focus my attention on clarifying the latter claim and Frege's motivations for making it, exposing what I take to be a fundamental tension in Frege's conception of logic. Finally, I discuss whether Frege's deployment of the horizontal in his mature Begriffsschrift helps to resolve this tension. (shrink)

Intelligent design begins with a seemingly innocuous question: Can objects, even if nothing is known about how they arose, exhibit features that reliably signal the action of an intelligent cause? To see what’s at stake, consider Mount Rushmore. The evidence for Mount Rushmore’s design is direct—eyewitnesses saw the sculptor Gutzon Borglum spend the better part of his life designing and building this structure. But what if there were no direct evidence for Mount Rushmore’s design? What if humans went extinct and (...) aliens, visiting the earth, discovered Mount Rushmore in substantially the same condition as it is now? (shrink)

Godwin's Political Justice is the founding work of philosophical anarchism. Drawing on the principles of liberty and utility Godwin criticizes government and all forms of secular and religious authority, advocating the free exercise of individual judgement. He raises enduring questions about the nature of our duty to others.

Recent attempts to show that functional processing entails the presence of phenomenal consciousness have failed to deliver the kind of answers to the “problems of consciousness” that anti-materialists insist the functionalist must provide. I will illustrate this by focusing on the claims that there is a special “Hard Problem” of consciousness and an “explanatory gap” between functional and phenomenal facts. I then argue that if we supplement the functionalist stories with a relationalist conception of phenomenal properties, we can begin to (...) see the shape of a naturalistic theory of phenomenal consciousness that will provide intuitively compelling responses to these problems.

The concept of locally specialized functions dominates research on higher brain function and its disorders. Locally specialized functions must be complemented by processes that coordinate those functions, however, and impairment of coordinating processes may be central to some psychotic conditions. Evidence for processes that coordinate activity is provided by neurobiological and psychological studies of contextual disambiguation and dynamic grouping. Mechanisms by which this important class of cognitive functions could be achieved include those long-range connections within and between cortical regions that (...) activate synaptic channels via NMDA-receptors, and which control gain through their voltage-dependent mode of operation. An impairment of these mechanisms is central to PCP-psychosis, and the cognitive capabilities that they could provide are impaired in some forms of schizophrenia. We conclude that impaired cognitive coordination due to reduced ion flow through NMDA-channels is involved in schizophrenia, and we suggest that it may also be involved in other disorders. This perspective suggests several ways in which further research could enhance our understanding of cognitive coordination, its neural basis, and its relevance to psychopathology. Key Words: attention; cerebral cortex; cognitive coordination; cognitive neuropsychiatry; cognitive neuropsychology; context disorganization; Gamma rhythms; Gestalt theory; glutamate; grouping; memory; NMDA-receptors; PCP-psychosis; perceptual organization; schizophrenia.

In his book, Can God Be Free?, William Rowe has argued that if God is unsurpassably good He cannot be free; if He is free, He cannot be unsurpassably good. After following the discussion of this topic through a number of historical figures, Rowe focuses on the recent and contemporary debate. A key claim of Rowe's is that, if there exists an endless series of better and better creatable worlds, then the existence of a morally perfect creator is impossible. (...) I show that this argument is unsound, since a key premise can be proved false from propositions Rowe himself accepts. (shrink)

This narrative scoping review examines ethical practice in educational and school psychology from a bioecological systems’ perspective. A search of four databases yielded 34 articles in the final narrative synthesis. Informed by Bronfenbrenner and Morris’ bioecological systems theory, the ethical experiences of educational and school psychologists were analyzed using the concepts of Process, Person, Context and Time. The complexity, intensity and frequency of ethical dilemmas are reviewed in Process. The demand, resource, and force characteristics impacting on psychologists as Person are (...) reviewed. Within Context, studies identified dilemmas that arose for psychologists across systems. In Time, issues including implications of the Fourth Industrial Revolution on psychologists’ ethical practice with the emergence of Artificial Intelligence are examined. This paper demonstrates the synergies and the interrelated influences on psychologists’ ethical practices arising from a systematic review of their experiences and their professional training needs.

Under the general heading of what we might loosely call emotional states, a familiar distinction can be drawn between emotions (strictly so-called) and moods. In order to judge under which of these headings a subject’s emotional episode falls, we advance a question of the form: What is the subject’s emotion of or about? In some cases (for example fear, sadness, and anger) the provision of an answer is straightforward: the subject is afraid of the loose tiger, or sad about England’s (...) poor performance in the World Cup, or angry with her errant child. Although the ways we find natural to talk in such situations can alter (afraid of, sad about, angry with, and so on), in each case the emotion has what Ronald de Sousa, following Wittgenstein, calls a target—“an actual particular to which that emotion relates.” (de Sousa, 1987, p.116).

A major problem for interpersonal aggregation is how to compare utility across individuals; a major problem for decision-making under normative uncertainty is the formally analogous problem of how to compare choice-worthiness across theories. We introduce and study a class of methods, which we call statistical normalization methods, for making interpersonal comparisons of utility and intertheoretic comparisons of choice-worthiness. We argue against the statistical normalization methods that have been proposed in the literature. We argue, instead, in favor of normalization of variance: (...) we claim that this is the account that most plausibly gives all individuals or theories ‘equal say’. To this end, we provide two proofs that variance normalization has desirable properties that all other normalization methods lack, though we also show how different assumptions could lead one to axiomatize alternative statistical normalization methods.

What does it mean to be a good thinker? Which virtues work together in someone who possesses good intellectual character? Although recent research on virtues has highlighted the benefits of individual intellectual virtues, being an excellent thinker is likely a function of possessing multiple intellectual virtues. Specifically, a good thinker would both recognize one’s intellectual shortcomings and possess an eagerness to learn driven by virtues such as love of knowledge, curiosity, and open-mindedness. Good intellectual character may only successfully manifest when (...) individuals possess not just one or a few intellectual virtues, but a larger set of such virtues to different degrees. However, little is currently known about what combination of virtues are necessary for good thinking. We argue that it is important to identify and clarify the nature of the good thinker and outline a profile methodology for achieving this goal. This approach characterizes the good thinker in terms of a profile of multiple intellectual virtues. Understanding this profile can allow greater insight into the extent to which people possess such a profile, and the potential for societal benefits of educating for these qualities. (shrink)

It is commonly supposed that citizens of a reasonably just state have a prima facie duty to obey its laws. In recent years, however, a number of influential political philosophers have concluded that there is no such duty. But how can the state be a legitimate authority if there is no general duty to obey its laws? This article is an attempt to explain how we can make sense of the idea of legitimate political authority without positing the existence of (...) a general duty to obey the law. The explanation makes use of a distinction between laws of general application, on one hand, and on the other the particularized, directed efforts by state officials to channel and resolve disputes (including those arising from violations of the law). A state's legitimate authority entails a general duty to cooperate in the latter type of effort, rather than upon a dubious general duty to obey the law. (shrink)

Scientific models may be more useful for false assumptions they make than true ones when one is interested not in the fit of the model, but in the form of the residuals. Modeling Darwin’s “blending” theory of inheritance shows how it illuminates features of Mendelian theory. Insufficient understanding of it leads to incorrect moves in modeling population structure. But it may prove even more useful for organizing a theory of cultural evolution. Analysis of “blending” inheritance gives new tools for recognizing (...) population structure for culture and for understanding differences between biological and cultural inheritance. (shrink)

This paper explores how to deliberate about food choices from a Stoic perspective informed by the value of environmental sustainability. This perspective is reconstructed from both ancient and contemporary sources of Stoic philosophy. An account of what the Stoic goal of “living in agreement with Nature” would amount to in dietary practice is presented. Given ecological facts about food production, an argument is made that Stoic virtue made manifest as wisdom, justice, courage, and temperance compel Stoic practitioners to select locally (...) sourced, low resource input, plant-based foods whenever circumstances allow.

By taking ‘existence in reality’ to be a great-making property and ‘God’ to be the greatest possible being, Plantinga skillfully presents Anselm’s ontological argument. However, since he proves God’s existence by virtue of a premise, “God (a maximally great being) is a possible being”, that is true only if God actually exists; his argument begs the question of the existence of God.

This paper is concerned with the normative content of Kant's formula of humanity (FH). More specifically, does FH, as some seem to think, imply the specific and rigid prescriptions in 'standard' deontological theories? To this latter question, I argue, the answer is 'no'. I propose reading FH largely through the formula of autonomy and the formula of the kingdom of ends, where I understand FA to describe the nature of the capacity of humanity-a capacity for self-governance. The latter, I suggest, (...) is akin to the capacity for planning and intentional action described in Michael Bratman's work. A significant part of what FH requires, I then propose, is that we exercise these capacities for planning in such a way that we accommodate and coordinate with the (permissible) plans and intentions of others. Kant himself, as do many commentators, emphasizes the idea that our human capacities give us a distinctive kind of value. On my interpretation, by contrast, what is fundamentally important is not the value of the capacities but rather what they make possible: distinctive ways of mistreating (using) persons, but also a distinctive kind of morally desirable relationship.

According to religious pluralism, the profound differences among the chief objects of adoration in the great religious traditions are largely due to the different ways in which a single transcendent reality is experienced and conceived in human life. The most prominent developer and defender of religious pluralism in the twentieth century is John Hick. Hick uses the expression ‘the Real’ to designate the transcendent reality ‘authentically experienced’ as the different gods and impersonal absolutes worshipped in the major religious traditions. A (...) central claim Hick makes is that, apart from some purely formal characteristics, the Real is ineffable in that the intrinsic properties making up its nature are beyond the scope of any human concepts. I explore this central claim and argue that it implies the dubious, if not incoherent, view that the Real in itself has neither one of many pairs of contradictory properties. (shrink)

This essay examines lines of connection between disgust, the effect of disciplines upon such intensive appraisals, political action, and the shape of ethical responsiveness. Philosophies that espouse purity in moral ity or politics mask these lines of connection; they thereby disparage the sig nificance of techniques of the self to ethical and political life. Immanuel Kant and Hannah Arendt provide the two main figures through whom these themes are explored. Arendt and Kant are brought into relation with each other through (...) the way each comes to terms with disgust and common sense. Kant's attempt to purify morality draws upon the spontaneity of common sense even more than it does upon a set of transcendental arguments. The Kantian metaphysic of the supersensible and the sensible then authorizes a concept of morality that almost removes the will beyond the reach of disci plines. But aporias he confronts within the will may bring these tactics back in. Arendt, while rising above the command conception of morality pro jected by Kant through her invocation of gratitude for being and appre ciation of new beginnings, reinstates purity in the concept of 'the political'. Arendt's drive to bracket the body - often treated as an assemblage of com pulsive moods and interests - from the realm of ethical and political life also disparages tactics by the self on the self. To challenge the metaphysic of the supersensible and the sensible with a metaphysic of the infrasensible and the sensible is to confirm the nobility of such tactics. The presentation of this alternative perspective calls into question the pretension of many contemporaries to be 'post-metaphysical'; it also helps to show why meta physical pluralism sets a condition for a politics of plurality attuned to the velocity and scope of late-modern life.

“The great field for new discoveries,” said a scientific friend to me the other day, “is always the Unclassified Residuum.” Round about the accredited and orderly facts of every science there ever floats a sort of dust-cloud of exceptional observations, of occurrences minute and irregular, and seldom met with, which it always proves less easy to attend to than to ignore. The ideal of every science is that of a closed and completed system of truth. The charm of most sciences (...) to their more passive disciples consists in their appearing, in fact, to wear just this ideal form. Each one of our various ologies seems to offer a definite head of classification for every possible phenomenon of the sort which it professes to cover; and, so far from free is most men’s fancy, that when a consistent and organized scheme of this sort has once been comprehended and assimilated, a different scheme is unimaginable. No alternative, whether to whole or parts, can any longer be conceived as possible. Phenomena unclassifiable within the system are therefore paradoxical absurdities, and must be held untrue. When, moreover, as so often happens, the reports of them are vague and indirect, when they come as mere marvels and oddities rather than as things of serious moment, one neglects or denies them with the best of scientific consciences. Only the born geniuses let themselves be worried and fascinated by these outstanding exceptions, and get no peace till they are brought within the fold. Your Galileos, Galvanis, Fresnels, Purkinjes, and Darwins are always getting confounded and troubled by insignificant things. Anyone will renovate his science who will steadily look after the irregular phenomena. And when the science is renewed, its new formulas often have more of the voice of the exceptions in them than of what were supposed to be the rules. (shrink)

Now under what circumstances is a conditional true? Even to raise this question is to depart from everyday attitudes. An affirmation of the form ‘if p then q’ is commonly felt less as an affirmation of a conditional than as a conditional affirmation of the consequent…. If, after we have made such an affirmation, the antecedent turns out true, then we consider ourselves committed to the consequent, and are ready to acknowledge error if it proves false. If on the other (...) hand the antecedent turns out to have been false, our conditional affirmation is as if it had never been made. (shrink)

New discoveries about materials and solar energy raise the possibility of a long-tenn shift of mining, refining, and manufacturing from Earth’s surface to locations outside Earth’s ecosphere, allowing Earth to begin to relax back toward its natural state. A little-discussed ambivalence toward the potential of space exploration exists among environmentalists. One camp sees it as a human adventure that may allow a bold initiative to improve Earth; another camp shies away from “heavy technology” and thus distrusts efforts as massive as (...) space exploration or utilization. Due to impending resource depletion on Earth, we may have only until the mid-twenty-first century to pursue the promising potential of space exploration to alleviate environmental problems of Earth. Subsequently, there may be too litde industlial base to support vigorous exploration and exploitation of resources in space. (shrink)

This essay discusses engineering ethics in Puerto Rico by examining the impact of the Colegio de Ingenieros y Agrimensores de Puerto Rico (CIAPR) and by outlining the constellation of problems and issues identified in workshops and retreats held with Puerto Rican engineers. Three cases developed and discussed in these workshops will help outline movements in engineering ethics beyond the compliance perspective of the CIAPR. These include the Town Z case, Copper Mining in Puerto Rico, and a hypothetical case researched by (...) UPRM students on laptop disposal. The last section outlines four future challenges in engineering ethics pertinent to the Puerto Rican situation. (shrink)

In conclusion, then, the notion of temporal necessity is certainly queer and perhaps a misnomer. It really has little to do with temporality per se and everything to do with counterfactual openness or closedness. We have seen that the future is as unalterable as the past, but that this purely logical truth is not antithetical to freedom or contingency. Moreover, we have found certain past facts are counterfactually open in that were future events or actualities to be other than they (...) will be, these past facts would have been different as a consequence. God's beliefs about the future are such past facts. Moreover, the effects of actions which God would have taken had He believed differently are also such past facts. Oddly enough, then, virtually any past fact is potentially counterfactually open, and the only necessity that remains is purely de facto. We, of course, do not in general know which events of the past depend counterfactually on present actions, and those cases we do know about seem rather trivial. Our intuitions of the necessity, unalterability, and unpreventability of the past as opposed to the future stem from the impossibility of backward causation, which is precluded by the dynamic nature of time and becoming. But the counterfactual dependence of God's beliefs on future events or actualities is not a case of backward causation: rather future-tense propositions are true in virtue of what will happen, given a view of truth as correspondence, and God simply has the essential property of knowing all and only true propositions. With regard to the future, virtually all facts are counterfactually open, and therefore future-tense propositions are not temporally necessary. Propositions thus move from being temporally contingent to being temporally necessary when all the opportunities to affect things counterfactually have slipped by. Hence, the mere fact that an event is past is no indication that it is counterfactually closed. This is especially evident in the case of God's foreknowledge. If we say that God foreknows that I shall do x and therefore I cannot refrain from doing x, lest I change God's past foreknowledge, we are being deceived by a modality which has nothing to do with my power or freedom. All that is impossible is the conjunction of God's foreknowledge that p and of ~ p; but this modality in sensu composito has no bearing on my ability to act such that ~ p would be true and God would have foreknown differently. Temporal necessity, then, turns out to be only obliquely temporal and modally weak, certainly no threat to freedom or divine foreknowledge. (shrink)

In the past two decades, reinforcement learning has become a popular framework for understanding brain function. A key component of RL models, prediction error, has been associated with neural signals throughout the brain, including subcortical nuclei, primary sensory cortices, and prefrontal cortex. Depending on the location in which activity is observed, the functional interpretation of prediction error may change: Prediction errors may reflect a discrepancy in the anticipated and actual value of reward, a signal indicating the salience or novelty of (...) a stimulus, and many other interpretations. Anterior cingulate cortex has long been recognized as a region involved in processing behavioral error, and recent computational models of the region have expanded this interpretation to include a more general role for the region in predicting likely events, broadly construed, and signaling deviations between expected and observed events. Ongoing modeling work investigating the interaction between ACC and additional regions involved in cognitive control suggests an even broader role for cingulate in computing a hierarchically structured surprise signal critical for learning models of the environment. The result is a predictive coding model of the frontal lobes, suggesting that predictive coding may be a unifying computational principle across the neocortex. (shrink)

In this book William G. Lycan offers an epistemology of philosophy itself, a partial method for philosophical inquiry. The epistemology features three ultimate sources of justified philosophical belief. First, common sense, in a carefully restricted sense of the term-the sorts of contingentpropositions Moore defended against idealists and skeptics. Second, the deliverances of well confirmed science. Third and more fundamentally, intuitions about cases in a carefully specified sense of that term. The first half of On Evidence in Philosophy expounds a (...) version of Moore's method and applies it to each of several issues. This version is shown to resist all the standard objections to Moore; most of them do not even apply. It is argued, in Chapters 5 and 6, that philosophical method is far lesspowerful than most have taken it to be. In particular, deductive argument can accomplish very little, and hardly ever is an opposing position refuted except by common sense or by science. The final two chapters defend the evidential status of intuitions and the Goodmanian method of reflectiveequilibrium; it is argued that philosophy always and everywhere depends on them. The method is then set within a more general explanatory-coherentist epistemology, which is shown to resist standard forms of skepticism.In sum, William G. Lycan advocates a picture of philosophy as a very wide explanatory reflective equilibrium incorporating common sense, science, and our firmest intuitions on any topic-and nothing more, not ever.

Arne Naess and Paul Taylor are two of the most forceful proponents of the principle of species equality. Problematically, both, when adjudicating conflict of interest cases, resort to employing explicit or implicit species-ranking arguments. I examine how Lawrence Johnson’s critical, species-ranking approach helpfully avoids the normative inconsistencies of “biospherical egalitarianism.” Many assume species-ranking schemes are rooted in arrogant, ontological claims about human, primate, or mammalian superiority. Species-ranking, I believe, is best viewed as a justified articulation of moral priorities in response (...) to individuals’ or entities’ relative ranges of vulnerability and need, rooted in their relative ranges of capacities and interests.
