A model (based on a proposal by Schick (1974), is developed for channels composed of four species; the channels allow conduction when all species are in the correct configuration. Allowance is also made for diffusion resulting from depletion of ions in the neighbourhood of the channel. The result is a series of pulses in which the current falls as –1/2 upon closing the channel. The resulting power spectrum is calculated according to the method given by Schick and earlier workers, and (...) is found to be, at least qualitatively, in agreement with many of the features of noise measured for certain types of nerve membranes. The calculations are not linearized, but are carried through numerically. (shrink)

Radical ecology typically brings to mind media images of ecological activists standing before loggers' saws, staging anti-nuclear marches, and confronting polluters on the high seas. Yet for more than twenty years, the activities of organizations such as the Greens and Earth First! have been influenced by a diverse, less-publicized group of radical ecological philosophers. It is their work—the philosophical underpinnings of the radical ecological movement—that is the subject of _Contesting Earth's Future_. The book offers a much-needed, balanced appraisal of radical (...) ecology's principles, goals, and limitations. Michael Zimmerman critically examines the movement's three major branches—deep ecology, social ecology, and ecofeminism. He also situates radical ecology within the complex cultural and political terrain of the late twentieth century, showing its relation to Martin Heidegger's anti-technological thought, 1960s counterculturalism, and contemporary theories of poststructuralism and postmodernity. An early and influential ecological thinker, Zimmerman is uniquely qualified to provide a broad overview of radical environmentalism and delineate its various schools of thought. He clearly describes their defining arguments and internecine disputes, among them the charge that deep ecology is an anti-modern, proto-fascist ideology. Reflecting both the movement's promise and its dangers, this book is essential reading for all those concerned with the worldwide ecological crisis. (shrink)

This paper places Julian Schwinger's development of the Euclidean Green's function formalism for quantum field theory in historical context. It traces the techniques employed in the formalism back to Schwinger's work on waveguides during World War II, and his subsequent formulation of the Minkowski space Green's function formalism for quantum field theory in 1951. Particular attention is dedicated to understanding Schwinger's physical motivation for pursuing the Euclidean extension of this formalism in 1958.

This volume is a collection of essays by various contributors in honor of the late Laurence Berns, Richard Hammond Elliot Tutor Emeritus at St. John's College, Annapolis.

Many biologists appeal to the so-called Krogh principle when justifying their choice of experimental organisms. The principle states that “for a large number of problems there will be some animal of choice, or a few such animals, on which it can be most conveniently studied”. Despite its popularity, the principle is often critiqued for implying unwarranted generalizations from optimal models. We argue that the Krogh principle should be interpreted in relation to the historical and scientific contexts in which it has (...) been developed and used. We interpret the Krogh Principle as a heuristic, i.e., as a recommendation to approach biological problems through organisms where a specific trait or physiological mechanism is expected to be most distinctively displayed or most experimentally accessible. We designate these organisms “Krogh organisms.” We clarify the differences between uses of model organisms and non-standard Krogh organisms. Among these is the use of Krogh organisms as “negative models” in biomedical research, where organisms are chosen for their dissimilarity to human physiology. Importantly, the representational scope of Krogh organisms and the generalizability of their characteristics are not fixed or assumed but explored through experimental studies. Research on Krogh organisms is steeped in the comparative method characteristic of zoology and comparative physiology, in which studies of biological variation produce insights into general physiological constraints. Accordingly, we conclude that the Krogh principle exemplifies the advantages of studying biological variation as a strategy to produce generalizable insights. (shrink)

Neste ensaio, argumento que qualquer um que adotasse um falsificacionismo do tipo que tenho atribuído a Nietzsche se sentiria atraído pela doutrina do eterno retorno. Para Nietzsche, pensar o 'vir a ser' revelado por meio dos sentidos significa falsificá-lo por meio do 'ser'. Mas o eterno retorno oferece a possibilidade de pensar o 'vir a ser' sem falsificação. Em seguida, argumento que qualquer um que mantenha o falsificacionismo de Nietzsche veria na ação humana um conflito entre o 'ser' e o (...) 'vir a ser', de modo semelhante ao que ocorre no juízo empírico. À luz desse conflito apenas o eterno retorno ofereceria a possibilidade de afirmar a vida de modo verdadeiro. Para concluir, discuto de que maneira tal leitura do eterno retorno resolve uma série de enigmas que têm atormentado os intérpretes. In this essay, I argue that someone who adopted a falsificationism of the sort that I have attributed to Nietzsche would be attracted to the doctrine of eternal recurrence. For Nietzsche, to think the becoming revealed through the senses means falsifying it through being. But the eternal recurrence offers the possibility of thinking becoming without falsification. I then argue that someone who held Nietzsche's falsificationism would see in human agency a conflict between being and becoming similar to that in empirical judgment. In the light of this conflict only the eternal recurrence would offer the possibility of truly affirming life. I end by discussing how this reading of the eternal recurrence solves a number of puzzles that have bedeviled interpreters. (shrink)

An agent is one who regulates his/her own actions through positive and negative feedback. It is painful for a rational being to set himself a task and then find himself unable to complete it entirely as he/she conceives it. To escape this pain, a person may use self-deception to avoid such negative feedback. When this denial becomes universalized, an agent can no longer function as a self-regulating, cybernetic system, i.e., as an agent who directs his/her own actions. Ten types of (...) moral self-deception are distinguished, and the duty of moral self-knowledge is clarified. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:141 HUME AND CAUSAL INFERENCE Hume held that any time we reach by inference a belief about the existence or qualities of some object or event that we have not actually perceived, the inference is grounded in beliefs about causal relations holding between the object of belief and some other object or objects that have actually been experienced. I will examine here Hume's account of such causal inferences. There (...) are many places in the Treatise of Human Nature at which Hume seems to claim that causal inferences take place when and only when the percipient has had an extensive previous experience of objects of the respective types as regularly conjoined in relations of contiguity and temporal priority. It seems to me that reliance on these passages alone gives a distorted view of Hume's theory of causal inference. Contrary to appearances, Hume did not hold that extensive previous experiences of objects of the same types as properly conjoined is either necessary or sufficient for causal inference. Hume's view is more subtle and complicated, and there are important considerations of coherence and holism present in it. Getting Hume's view on this matter clear is important because it shows how he can escape some of the objections that have been laid against his theory, and it makes possible a reading of Hume as a causal realist. Hume's theory of inference provides the resources for drawing a distinction between accidental and genuine causal regularities and it is compatible with the view that causal relations (and not mere de facto regularities) hold among events in the world independently of their being perceived. The examination begins by looking at a different, but related, issue. Why does Hume think 142 that of the three types of association, only cause and effect association is capable of producing belief? Hume puts the question in the form of a possible objection to his account. For it may be said, that if all the parts of that hypothesis be true, viz. that these three species of relation are deriv'd from the same principles; that their effects in inforcing and inlivening our ideas are the same; and that belief is nothing but a more forcible and vivid conception of an idea; it shou'd follow, that that action of the mind may not only be deriv'd from the relation of cause and effect, but also from those of contiguity and resemblance. But as we find by experience, that belief arises only from causation, and that we can draw no inference from one object to another, except they be connected by this relation, we may conclude, that there is some error in that reasoning, which leads us into such difficulties. (T 107) It is important to note that Hume is talking here only about beliefs about the existence or situations of objects that have not been intuited or experienced. Beliefs about relations of ideas (e.g., that 2 + 2 = 4) are intuitions (or perhaps memories 2 of intuitions). Beliefs in the existence of things as experienced or in the previous existence of things as previously experienced automatically have the 3 vivacity of impressions or memory ideas. What Hume takes himself to need to explain is why cause and effect association allows for a transfer of this vivacity to an idea of an object or situation that has not itself been intuited or experienced and why 4 resemblance and contiguity association do not. If I see a green ball next to a red sweater, then I will normally subsequently believe that the green ball existed next to the red sweater at that time (at 143 least until my memories begin to lose vivacity). This is purely a matter of sense experience and memory. Now if I subsequently see a different red sweater (or the same sweater in a different location), I may be led to think of a green ball existing next to it purely through contiguity and resemblance association. But presumably I would not believe that a green ball existed next to the currently perceived red sweater unless I currently perceived a green ball or my belief was based on some 5 form of causal inference...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Intention and Wrongdoing: A Defense of the Principle of Double Effect by Joshua StuchlikMichael J. DegnanSTUCHLIK, Joshua. Intention and Wrongdoing: A Defense of the Principle of Double Effect. Cambridge: Cambridge University Press, 2021. xvi + 220 pp. Cloth, $99.99In this book Joshua Stuchlik vigorously defends the principle of double effect (PDE), which states, "There is a strict moral constraint against bringing about serious evil (harm) to an innocent (...) person intentionally, but it is permissible in a wider range of circumstances to act in a way that brings about serious evil incidentally, as a foreseen but non-intended side effect." After defining the terms of the principle and considering an intuitive case-based defense, he supports its truth based on a standard of solidarity. Since the PDE requires the distinction between intended consequences and nonintended side effects, he explains Elizabeth Anscombe's theory of intention, which supports the distinction's moral significance. He uses her theory to treat the closeness problem, the irrelevance of intention critique, and a challenge from Joshua Greene's empirical moral psychology that purports to undermine deontological constraints on causing harm.I present Stuchlik's grounding for the PDE followed by an uncontroversial example of its application. After this I consider two important objections to the PDE that Stuchlik critiques: the closeness problem and James Rachels's argument that intentions are irrelevant to judging the moral permissibility of actions. I conclude by examining Stuchlik's treatment of these challenges.Stuchlik interprets the PDE's very strict constraint against intentional killing or seriously harming the innocent as a near absolute prohibition, for he believes innocent persons are not suitable recipients of intentional harm. He grounds this constraint on the principle of solidarity. Being in solidarity with another is possessing concern for that other's sake. The ground for this concern is a shared human nature that enables members to think of themselves as making a "we." Human nature consists in the structured potentialities for knowing and freely choosing. Evidence of these rational potentialities is the human orientation toward the transcendent values of truth and goodness. Such embodied potentialities have inviolable worth.The scenarios of the precision bomber and the terror bomber illustrate the moral significance of the intended harm versus the nonintended but foreseen harm that Stuchlik adopts from Elizabeth Anscombe's action theory. Each bombers' goal is to help his country win a just war. The precision bomber pursues that goal by targeting a munitions factory. Though he foresees that many noncombatants will be killed or seriously [End Page 367] injured from the bomb, he does not necessarily intend these harms. By contrast, the terror bomber targets a civilian center necessarily intending harm for noncombatants. The PDE rules out his conduct.Anscombe's account of intention can lead to the problem of closeness in which the content of an intention is sufficiently fine-grained that an agent need not intend harm in almost any situation. Stuchlik illustrates the problem with Alexander Pruss's zookeeper scenario.An eccentric literalistic but always truthful magnate tells Sam he will donate to famine relief saving a hundred lives if and only if Sam follows his directions to the iota. Sam is to purchase a gun, sneak at night into a zoo owned by the magnate and kill the first mammal he sees. Sam sneaks into the zoo, sees a mammal in the distance, and forms the intention to shoot it. Then he notices that the mammal is human but shoots nonetheless on utilitarian grounds.In this case applying the PDE shows that Sam is simply intending that a mammal be killed. The fact that the mammal is a human is irrelevant, according to Anscombe's action theory.Stuchlik's response clarifies the scope of intention in the PDE. As stated above, the intention's content includes seriously harming an innocent human. However, if the intention ranges only over an intention to bring about an effect, E, and it turns out that E is a serious harm for an innocent human being, then applying the principle shows that Sam's action is wrong. The intended effect of killing the mammal is, as a matter of fact, an... (shrink)

Bradley's critique of abstract, atomic individualism in social and political theory addresses persistent shortcomings of liberalism. At the same time, his account of the growth of moral order in the individual offers a counterweight to excessively organicist theories of the moral self, which dissolve it into social context and undercut the possibility of non-social, non-trivial moral norms. This thesis argues that Bradley avoids this by complementing the contextual determination of individual ends with a developmental moral psychology that provides a conception (...) of human nature and specific ends which are not socially formed, and develops more fully his conception of the community as the embodiment of moral order. ;In the introduction I describe the development of atomic individualism in social theory and nineteenth century opposition to it. In chapters two and three I examine Bradley's critique of Mill's atomism and Michael Sandel's criticisms of Rawls's social theory and compare these criticisms. The comparison indicates significant agreement between communitarian criticisms of deontological liberalism and Bradley's critique of Mill. ;In chapters four through six I give an account of Bradley's moral psychology which explains his philosophical motivation for espousing social organicism. I examine the notion of self-realization as a psychological principle and make tangible the central importance Bradley gives to realization of the self as a whole. I consider: Bradley's basic psychological "law," its bearing on the early stages of moral development, the development of 'objective interests' which become constitutive of our mature moral identity, Bradley's formula for self-realization, and the nature of some concrete ends which give it substantial content. I incorporate these into a consideration of Bradley's conception of the community or 'moral organism,' and defend this from the objection that it requires strong metaphysical claims. ;In chapter seven I develop the conception further through a comparison of Bradley's ethics to A. E. Murphy's account of the language of moral reasons in The Theory of Practical Reason. My conclusion indicates its present importance by relating it to a recent study of ethical culture in America--Habits of the Heart--and by suggesting its potentially salutary effects. (shrink)

We are purposive agents; but we—adult humans in a broadly modern world—are more than that. We are reflective about our motivation. We form prior plans and policies that organize our activity over time. And we see ourselves as agents who persist over time and who begin, develop, and then complete temporally extended activities and projects. Any reasonably complete theory of human action will need in some way to advert to this trio of features—to our reflectiveness, our planfulness, and our conception (...) of our agency as temporally extended. These are, further, features that have great significance for the kinds of lives we can live. For these two reasons I will say that these are among the core features of human agency. A theory of human action needs to say what these core features consist in and how they are related to each other. And such a theory needs also to clarify the relation between these core features of our agency and the possibility that we are fully embedded in an event causal order. (shrink)

Thus far, we know much more about the significant outcomes of perceived ethical leadership than we do about its antecedents. In this study, we focus on multiple types of ethical role models as antecedents of perceived ethical leadership. According to social learning theory, role models facilitate the acquisition of moral and other types of behavior. Yet, we do not know whether having had ethical role models influences follower perceptions of one’s ethical leadership and, if so, what kinds of role models (...) are important. We conducted a field study, surveying supervisors and their subordinates to examine the relationship between three types of ethical role models and ethical leadership: the leader’s childhood role models, career mentors, and top managers. We found that having had an ethical role model during the leader’s career was positively related to subordinate-rated ethical leadership. As expected, this effect was moderated by leader age, such that the relationship between career mentoring and ethical leadership was stronger for older leaders. Leader age also moderated the relationship between childhood models and ethical leadership ratings, such that having had childhood ethical role models was more strongly and positively related to ethical leadership for younger leaders. We found no effect for top management ethical role models. Implications for research and practice are discussed. (shrink)

Although computation and the science of physical systems would appear to be unrelated, there are a number of ways in which computational and physical concepts can be brought together in ways that illuminate both. This volume examines fundamental questions which connect scholars from both disciplines: is the universe a computer? Can a universal computing machine simulate every physical process? What is the source of the computational power of quantum computers? Are computational approaches to solving physical problems and paradoxes always fruitful? (...) Contributors from multiple perspectives reflecting the diversity of thought regarding these interconnections address many of the most important developments and debates within this exciting area of research. Both a reference to the state of the art and a valuable and accessible entry to interdisciplinary work, the volume will interest researchers and students working in physics, computer science, and philosophy of science and mathematics.

There is a deeply entrenched view in philosophy and physics, the closed systems view, according to which isolated systems are conceived of as fundamental. On this view, when a system is under the influence of its environment this is described in terms of a coupling between it and a separate system which taken together are isolated. We argue against this view, and in favor of the alternative open systems view, for which systems interacting with their environment are conceived of as (...) fundamental, and the environment's influence is represented via the dynamical equations that govern the system's evolution. Taking quantum theories of closed and open systems as our case study, and considering three alternative notions of fundamentality: (i) ontic fundamentality, (ii) epistemic fundamentality, and (iii) explanatory fundamentality, we argue that the open systems view is fundamental, and that this has important implications for the philosophy of physics, the philosophy of science, and for metaphysics.

The doctrine of double effect has a firm, respected position within Roman Catholic medical ethics. Neil M.

Suppose you resolve now to resist an expected temptation later while knowing that once the temptation arrives your preference or evaluative assessment will shift in favor of that temptation. Are there defensible norms of rational planning agency that support sticking with your prior intention in the face of such a shift at the time of temptation and in the absence of relevant new information? This article defends the idea that it might be rational to stick with your prior intention in (...) part because of your anticipation of regret in the further future if you were to give in to the temptation. It does this by appeal to the significance of anticipated future regret to the agent ’s present standpoint, and to the role of the agent ’s standpoint in her self-governance. (shrink)

You can sometimes have and be moved by desires which you in some sense disown. The problem is whether we can make sense of these ideas of---as I will say---ownership and rejection of a desire, without appeal to a little person in the head who is looking on at the workings of her desires and giving the nod to some but not to others. Frankfurt's proposed solution to this problem, sketched in his 1971 article, has come to be called the (...) hierarchical model. Indeed, it seems that, normally, if an agent's relevant higher-order attitudes are not to some extent shaped by her evaluative reflections and judgments her agency will be flawed. But this suggests a Platonic challenge to the hierarchical account of ownership. The challenge is to explain why we should not see such evaluative judgments---rather than broadly Frankfurtian higher-order attitudes---as the fundamental basis of ownership or rejection of desire. I do think that a systematic absence of connection between higher-order Frankfurtian attitude and evaluative judgment would be a breakdown in proper functioning. But I want to explain how we can grant this point and still block the Platonic challenge. (shrink)

In autonomous action the agent herself directs and governs the action. But what is it for the agent herself to direct and to govern? One theme in a series of articles by Harry G. Frankfurt is that we can make progress in answering this question by appeal to higher-order conative attitudes. Frankfurt's original version of this idea is that in acting of one's own free will, one is not acting simply because one desires so to act. Rather, it is also (...) true that this desire motivates one's action because one desires that this desire motivate one's action. This latter desire about the motivational role of one's desire is a second-order desire. It is, in particular, what Frankfurt calls a second-order “volition.” And, according to Frankfurt's original proposal, acting of one's own free will involves in this way such second-order, and sometimes yet higher order, volitions.

I consider two inter-related problems in the philosophy of action. One concerns the role of the agent in the determination of action, and I call it the problem of agential authority. The other concerns the relation between motivating desire and the agent's normative deliberation, and I call it the problem of subjective normative authority. In part by way of discussion of work of Harry Frankfurt and Christine Korsgaard, I argue that we make progress with these problems by appeal to certain (...) kinds of higher-order policies and to their role in the cross-temporal organization of the deliberation and action of temporally persisting agents like us.

I argue that our judgements regarding the locally causal models that are compatible with a given constraint implicitly depend, in part, on the context of inquiry. It follows from this that certain quantum no-go theorems, which are particularly striking in the traditional foundational context, have no force when the context switches to a discussion of the physical systems we are capable of building with the aim of classically reproducing quantum statistics.

ABSTRACT:Despite sustained attention to ethical leadership in organizations, scholarship remains largely descriptive. This study employs an empirical approach to examine the consequences of ethical leadership on leader promotability. From a sample of ninety-six managers from two independent organizations, we found that ethical leaders were increasingly likely to be rated by their superior as exhibiting potential to reach senior leadership positions. However, leaders who displayed increased ethical leadership were no more likely to be viewed as promotable in the near-term compared to (...) those who displayed less ethical leadership. Our findings also show ethical culture and pressure to achieve results are important contextual factors that moderate the relationships between ethical leadership and leader promotability to senior leadership roles.

Cases of modest sociality are cases of small scale shared intentional agency in the absence of asymmetric authority relations. I seek a conceptual framework that adequately supports our theorizing about such modest sociality. I want to understand what in the world constitutes such modest sociality. I seek an understanding of the kinds of normativity that are central to modest sociality. And throughout we need to keep track of the relations—conceptual, metaphysical, normative—between individual agency and modest sociality. In pursuit of these (...) theoretical aims, I propose that a central phenomenon is shared intention. I argue that an adequate understanding of the distinctiveness of the intentions of individuals allows us to provide a construction of attitudes of the participants, and of relevant inter-relations and contexts that constitutes shared intention. I explain how shared intention, so understood, differs from a simple equilibrium within common knowledge. And I briefly contrast my views with aspects of views of John Searle and Margaret Gilbert.

From the philosopher’s perspective, the interest in quantum computation stems primarily from the way that it combines fundamental concepts from two distinct sciences: Physics, in particular Quantum Mechanics, and Computer Science, each long a subject of philosophical speculation and analysis in its own right. Quantum computing combines both of these more traditional areas of inquiry into one wholly new, if not quite independent, science. Over the course of this chapter we will be discussing some of the most important philosophical questions (...) that arise from this merger and philosophical lessons to be learned. (shrink)

A primary goal of quantum computer science is to find an explanation for the fact that quantum computers are more powerful than classical computers. In this paper I argue that to answer this question is to compare algorithmic processes of various kinds and to describe the possibility spaces associated with these processes. By doing this, we explain how it is possible for one process to outperform its rival. Further, in this and similar examples little is gained in subsequently asking a (...) how-actually question. Once one has explained how-possibly, there is little left to do. (shrink)

A considerable body of research has documented the emergence of what appears to be instrumental helping behavior in early childhood. The current study tested the hypothesis that one basic psychological mechanism motivating this behavior is a preference for completing unfinished actions. To test this, a paradigm was implemented in which 2-year-olds (n = 34, 16 female/18 male, mostly White middle-class children) could continue an adult’s action when the adult no longer wanted to complete the action. The results showed that children (...) continued the adult’s actions more often when the goal had been abandoned than when it had been reached (OR = 2.37). This supports the hypothesis that apparent helping behavior in 2-year-olds is motivated by a preference for completing unfinished actions. (shrink)

I flesh out the sense in which the informational approach to interpreting quantum mechanics, as defended by Pitowsky and Bub and lately by a number of other authors, is (neo-)Bohrian. I argue that on this approach, quantum mechanics represents what Bohr called a “natural generalisation of the ordinary causal description” in the sense that the idea (which philosophers of science like Stein have argued for on the grounds of practical and epistemic necessity) that understanding a theory as a theory of (...) physics requires that one be able to “schematise the observer” within it is elevated in quantum mechanics to the level of a postulate in the sense that interpreting the outcome of a measurement interaction, as providing us with information about the world, requires as a matter of principle, the specification of a schematic representation of an observer in the form of a ‘Boolean frame’—the Boolean algebra representing the yes-or-no questions associated with a given observable representative of a given experimental context. I argue that the approach’s central concern is with the methodological question of how to assign physical properties to what one takes to be a system in a given experimental context, rather than the metaphysical question of what a given state vector represents independently of any context, and I show how the quantum generalisation of the concept of an open system may be used to assuage Einstein’s complaint that the orthodox approach to quantum mechanics runs afoul of the supposedly fundamental methodological requirement to the effect that one must always be able, according to Einstein, to treat spatially separated systems as isolated from one another.

We are purposive agents; but we—adult humans in a broadly modern world—are more than that. We are reflective about our motivation. We form prior plans and policies that organize our activity over time. And we see ourselves as agents who persist over time and who begin, develop, and then complete temporally extended activities and projects. Any reasonably complete theory of human action will need in some way to advert to this trio of features—to our reflectiveness, our planfulness, and our conception (...) of our agency as temporally extended. These are, further, features that have great significance for the kinds of lives we can live. For these two reasons I will say that these are among the core features of human agency. A theory of human action needs to say what these core features consist in and how they are related to each other. And such a theory needs also to clarify the relation between these core features of our agency and the possibility that we are fully embedded in an event causal order. (shrink)

I [try] to understand identification by appeal to phenomena of deciding to treat, and of treating, a desire of one's as reason-giving in one's practical reasoning, planning, and action. Is identification, so understood, "fundamental," as Frankfurt says, "to any philosophy of mind and of action"? Well, we have seen reason to include in our model of intentional agency such phenomena of deciding to treat, and of treating, certain of one's desires as reason-giving. Identification, at bottom, consists in such phenomena — (...) or so I have proposed. Given that such phenomena are important in our practical lives, we may agree with Frankfurt that identification is, in this sense, "fundamental.". (shrink)
