The mass extinction visited upon us by capitalism involves many kinds of devastation. Here I clarify the grounds for assessing the most obvious of these harms, i.e., decimation of species diversity. The thesis that variety among species has intrinsic value motivates, and in turn follows from, the “variable value view” (VVV) of abundance within any given species. In contrast, standard axiologies have no place for the intrinsic value of species diversity. I show that the VVV provides a better justification than (...) the latter do, of the way in which a widely-used empirical indicator summarizes the overall state of life on Earth. These considerations favor ecocentric value theory – which ascribes intrinsic value to properties of ecological wholes, like species diversity, that do not supervene on the well-being of their constituent organisms – over its main competitors. I conclude by widening the focus from wild nature alone to the biosphere comprising both wilderness and the domesticated realm. This broadened perspective helps to link the science and ethics of biodiversity with the political struggle to extract ourselves from the moral abyss of mass extinction. (shrink)

Ecologists typically invoke "law-like" generalizations, ranging over "structural" and/or "functional" kinds, in order to explain generalizations about "historical" kinds (such as biological taxa)rather than vice versa. This practice is justified, since structural and functional kinds tend to correlate better with important ecological phenomena than do historical kinds. I support these contentions with three recent case studies. In one sense, therefore, ecology is, and should be, more nomothetic, or law-oriented, than idiographic, or historically oriented. This conclusion challenges several recent philosophical claims (...) about the nature of ecological science. (shrink)

Scientists must sometimes choose between competing definitions of key terms. The degree to which different definitions facilitate important discoveries should ultimately guide decisions about which terms to accept. In the short run, rules of thumb can help. One such rule is to regard with suspicion any definition that turns a seemingly important empirical matter into an a priori exercise. Several prominent definitions of ecological “stability” are suspect, according to this rule. After evaluating alternatives, I suggest that the faulty definitions resulted (...) from an overemphasis on population dynamics in community ecology. Machine metaphors of nature may have given rise to a related problem of experimental design. (shrink)

Richness theory offers an alternative to the paradigms that have dominated the short history of environmental ethics as a self-conscious field. This alternative theoretical paradigm defines intrinsic value as “richness”—a synonym for “organic unity” or “unity in diversity.” Richness theory can handily reconcile two kinds of ideas that seem to be in tension with each other:that (1) an individual human being has a greater worth than an individual organism of just about any other species; and (2) yet the world would (...) be a better place with substantially fewer humans and/or less consumption per capita, thus leaving more resources for other species.The mutual compatibility of such ideas within the framework of richness theory can be demonstrated both verbally and through a simplified mathematical model.

In this paper, I offer a new defense of scientific realism, tailored for the Akaikean paradigm of statistical hypothesis testing. After proposing definitions of verisimilitude and predictive success, I use computer simulations to show how the latter depends on the former, even in the kind of case featured in a recent argument for instrumentalism.

Richness theory offers a promising axiology. In this paper, I discuss how to translate it into a deontology. To do so, I recruit the concept of moral distance from a recently developed epistemology, and construe it in terms of causal power. Finally, I apply the resulting decision-theoretic framework to the question of how best to avert ecological disaster over the next 36 years and achieve ecological harmony over the next 986.

Lewis' argument against the Limit Assumption and Pollock's Generalized Consequence Principle together suggest that "minimal-change" theories of counterfactuals are wrong. The "small-change" theories presented by Nute do not say enough. While these theories rely on closeness between possible worlds, I base an alternative on the ceteris paribus concept. My theory solves a problem that the above cannot, and is more relevant to the philosophy of science. Ceteris paribus conditions should normally include the causes, but exclude the effects, of the negated (...) antecedent. An example from community ecology, the debate over null models in island-biogeographical studies of competition, supports these arguments. (shrink)

When data are limited, simple models of complex ecological systems tend to wind up closer to the truth than more complex models of the same systems. This greater proximity to the truth, or verisimilitude, leads to greater predictive success. When more data are available, the advantage of simplicity decreases, and more complex models may gain the upper hand. In ecology, holistic models are usually simpler than reductionistic models. Thus, when data are limited, holistic models have an advantage over reductionistic models, (...) with respect to verisimilitude and predictive success. I illustrate these points with models designed to explain and predict the numbers of species on islands. (shrink)

Virtually all historical treatments of just war recognize the importance of the account given by Thomas Aquinas in Summa theologiae II-II, q. 40, ?De bello?, where he outlines three conditions ? legitimate authority, just cause, and right intention ? for a justifiable use of armed force. It is, however, less well known that within the same section of the work (q. 50, a. 4) Aquinas extended his reflection on just war into a theory of military prudence. By placing generalship under (...) the category of ?prudence?, rather than ?art? or ?science?, he held that military command involves more than a morally neutral skill with victory as its sole aim. Building on the premise that service to the common good constitutes the overarching purpose of the military profession, Aquinas showed how the virtue of prudence provides an inner compass for decision-making amid the uncertainty and confusion of the battlefield.

Contrary to what has been alleged, the moral equivalence of combatants (MEC) is not a doctrine that was expressly developed by the traditional theorists of just war. Working from the axiom that just cause is unilateral, they did not embrace a conception of public war that included MEC. Indeed, MEC was introduced in the early fifteenth century as a challenge to the then reigning just war paradigm. It does not follow, however, that the distinction between private and public war had (...) no place in the traditional teaching. Thomas Aquinas and his successors did not analyse just war by extrapolation from the related idea of self-defense. Rather, they likened just war to a legal proceeding that could solely be undertaken by persons possessed of legitimate authority. For this reason, just war was first and foremost public war. Private war was deemed ?war? only in a secondary and reduced sense of the term. It was accordingly understood that public war should be waged and its morality judged by reference to a set of norms that are not directly reducible to those governing private self (and other)-defense.

Inquiring 'whether any war can be just', Thomas Aquinas famously responded that this may hold true, provided the war is conducted by a legitimate authority, for a just cause, and with an upright intention. Virtually all accounts of just war, from the Middle Ages to the current day, make reference to this threefold formula. But due in large measure to its very succinctness, Aquinas's theory has prompted contrasting interpretations. This book sets the record straight by surveying the wide range of (...) texts in his literary corpus that have bearing on peace and the ethics of war. Thereby emerges a coherent and nuanced picture of just war as set within his systematic moral theory. It is shown how Aquinas deftly combined elements from earlier authors, and how his teaching has fruitfully propelled inquiry on this important topic by his fellow scholastics, later legal theorists such as Grotius, and contemporary philosophers of just war.

As Jonathan Mann observed, the problem of AIDS-related stigma is inextricably bound to issues of health, human rights, and the law. Such stigma translates into feelings of fear and hostility directed at people with HIV. It finds expression in avoidance and ostracism of people with HIV, discrimination and violence against them, and public support for punitive policies and laws that restrict civil liberties while hindering AIDS prevention efforts. Being the target of stigma inflicts pain, isolation, and hardship on many people (...) with HIV, while the desire to avoid it deters some from being tested for HIV, seeking treatment, or practicing risk-reduction.

Some recent authors have argued that Aquinas deliberately integrated a pacifist outlook into his just war theory. Others, by contrast, have maintained that his rejection of pacifism was unequivocal. The present article attempts to set the historical record straight by an examination of Aquinas's writings on this topic. In addition to Q. 40, A. 1 of Summa theologiae II–II, the text usually cited in this connection, this article considers the biblical commentaries where Aquinas explains how the Gospel “precepts of patience,” (...) especially Matthew 5:39, “Do not resist evil,” should be interpreted in light of the doctrine of just war. The article concludes that Aquinas formulated a two-stage theory whereby pacifism was rejected as a suitable form of agency for the state (respublica), while it was affirmed as the appropriate response to evil for the agency of the church (ecclesia).

By accepting that the formal structure of human language is the key to understanding the uniquity of human culture and consciousness and by further accepting the late appearance of such language amongst the Cro-Magnon, I am free to focus on the causes that led to such an unprecedented threshold crossing. In the complex of causes that led to human being, I look to scholarship in linguistics, mythology, anthropology, paleontology, and to creation myths themselves for an answer. I conclude that prehumans (...) underwent an existential crisis, i.e., the realization of certain mortality, that could be borne only by the discovery-creation of the larger realm of symbolic consciousness once experienced as the sacred (but today we know it as "the world" – as opposed to our immediate natural environment and that of other animals). Thus, although we, the human species, are but one species among innumerable others, we differ in kind, not degree. This quality is our symbolically enabled self-consciousness, the fortress of cultural identity that empowers but also imprisons awareness. (shrink)

The phenomenon of inverse linking, where a noun phrase embedded within another behaves with respect to binding as though it were structurally independent, has proven challenging for theories of the syntax–semantics interface. In this paper I show that, using an LF-movement style approach to the syntax–semantics interface, we can derive all and only the appropriate meanings for such constructions using no semantic operations other than function application and composition. The solution relies neither on a proliferation of lexical ambiguity nor on (...) abandoning the idea that pronouns denote variables, but rather on a straightforward (and standard) reification of assignment functions, which allows us to define abstraction operators within our models.

When so much is being written on conscious experience, it is past time to face the question whether experience happens that is not conscious of itself. The recognition that we and most other living things experience non-consciously has recently been firmly supported by experimental science, clinical studies, and theoretic investigations; the related if not identical philosophic notion of experience without a subject has a rich pedigree. Leaving aside the question of how experience could become conscious of itself, I aim here (...) to demonstrate that the terms experience and consciousness are not interchangeable. Experience is a notoriously difficult concept to pin down, but I see non-conscious experience as based mainly in momentary sensations, relational between bodies or systems, and probably common throughout the natural world. If this continuum of experience — from non-conscious, to conscious, to self-transcending awareness — can be understood and accepted, radical constructivism (the “outside” world as a construct of experience) will gain a firmer foundation, panexperientialism (a living universe) may gain credibility, and psi will find its medium.

Cooper storage is a widespread technique for associating sentences with their meanings, used in diverse linguistic and computational linguistic traditions. This paper encodes the data structures and operations of cooper storage in the simply typed linear \-calculus, revealing the rich categorical structure of a graded applicative functor. In the case of finite cooper storage, which corresponds to ideas in current transformational approaches to syntax, the semantic interpretation function can be given as a linear homomorphism acting on a regular set of (...) trees, and thus generation can be done in polynomial time.

The book covers a wide range of topics and raises issues rarely touched on in the ethics-of-war literature, such as environmental concerns and the responsibility of bystanders.

During the inter war period, European Catholic authors exhibited two different approaches to the question of just war. One approach was articulated at the “Fribourg Conventus,” a 1931 meeting of French, Swiss, and German theologians, whose subsequent declaration (Conventus de bello, published in 1932) called for a reformulation of Catholic teaching based on the premise that the traditional just‐war doctrine had been superseded by developments in international law. A competing approach was articulated by the Dutch Jesuit Robert Regout, who maintained (...) that the just‐war doctrine could contribute to the formation of international law by providing a much‐needed normative foundation for the use of armed force by individual states in redress of their violated rights. After presenting these two approaches and explaining how they differ, this essay shows how the outlook of the Conventus de bello is reflected in subsequent papal statements on armed force—to the detriment of the traditional terminology of just war.

EVER SINCE PLOTINUS SOUGHT CLARITY in the notion of privation to dispel our human perplexity about evil, philosophers have debated whether this concept is adequate to the task. The intensity and scope of evil in the twentieth century—which has seen the horrors of world war and genocide—have added fuel to the debate. Can the idea of a falling away from the good, however refined, come anywhere close to capturing the calculation, the commitment, the energy, and the drive that underlie the (...) most virulent projects in malfeasance? While the privation account might appear a reasonable strategy for explaining passive wrongdoing—indifference to people in grave need, or cooperation with injustice—the more active and dynamic forms of evil would nevertheless seem to elude its conceptual net.

Jacques Maritain is widely recognized as one of the foremost Catholic philosophers of modern times. He wrote groundbreaking works in all branches of philosophy. For a period of about 10 years, beginning in 1933, he discussed matters relating to war and ethics. Writing initially about Gandhi, whose strategy of non-violence he sought to incorporate within a Christian conception of political action, Maritain proceeded to comment more specifically on the religious aspects of armed force in “On Holy War,” an essay about (...) the civil war then ongoing in Spain. After the outbreak of World War II in September 1939, Maritain penned a series of essays that sought to explain why the Anglo–French declarations of war were warranted on Christian just war principles. While the secondary literature on Maritain’s thought is extensive, thus far there has been little systematic exploration of his writings on war. In what follows I seek to remedy this lacuna, by examining how he conceptualized just war in the three phases outlined above. (shrink)

This essay is divided into two parts, deeply intermingled. Part I examines not only the origin of conscious experience but also how it is possible to ask of our own consciousness how it came to be. Part II examines the origin of experience itself, which soon reveals itself as the ontological question of Being. The chief premise of Part I is that symbolic communion and the categorizations of language have enabled human organisms to distinguish between themselves as actually existing entities (...) and their own immediate experience of themselves and their world. This enables them to reflect upon abstract concepts, including “self,” “experience,” and “world.” Symbolic communication and conceptualization grow out of identification, the act of first observing conscious experiencing and intimating what it is like, mimesis, a gestural protolanguage learned through imitation, and reflection, seeing oneself through the eyes of others. The step into actual intentional speech is made through self-assertion, narrative, and intersubjectivity. These three become the spiral of human cultural development that includes not only the adaptive satisfaction of our biological needs, but also the creativity of thought. With the mental-conceptual separation of subject and object – of self and world – the human ability to witness the universe (and each other) is the ground of our genuinely human quality. Consciousness gives human life its distinctively human reality. It is, therefore, one and the same ability that enables us to shape planet Earth by means of conceptual representations (rather than by means of our hands alone) while also awakening us to the significance of being. -/- Looking beyond human self-consciousness to investigate the origin and nature of awareness itself in Part 2, reductive objective materialism is found to be of little use. Direct experience also falls short in that, in order to be transformed into objective knowledge about itself, it must always be interpreted through and limited by the symbolic contexts of culture and the idiosyncratic conceptualizations of the individual. Awareness-in-itself must thus be considered ultimately unexplainable, but this may more indicate its inexpressible transcendence of all symbolic qualifiers than its nonexistence. It is suggested that awareness is not “self-aware” (as in deity) but is instead unknowing yet identical with the only true universal: the impetus of creative unfolding. Our human knowledge, as an expression of this unfolding, is seen to emerge from our conscious experiencing and, in turn, to have the power – and enormous responsibility – of directing that experience. Our underlying symbolic worldviews are found to be autopoietic: They limit or open our conscious experience, which, in turn, confirms those worldview expectations. As we explore a future of unforeseeable technological breakthroughs on an ailing planet who patiently copes with our “success,” truly vital decisions about the nature, meaning, extent, and future of conscious experience will have to be made.

Role models can be highly influential in conveying ethical standards. This study investigates the influence various categories of role models have had on a population of over 1,600 undergraduate students in Texas, Oregon and Michigan. Those identifying clergy, boy scout leaders, friends and college advisors as role models exhibited less willingness to adopt questionable ethical behavior in negotation situations. Journalist and spouse role models tended to cause students to be more accepting of questionable behavior. Individuals with strong end-result and social (...) contract ethical philosophies, as well as males and those who served in the military exhibited strong tendencies toward less than ethical behavior. Individuals with strong rule ethical philosophy, high levels of religiousity, and those with a cooperative attitude in negotiations tended to adopt higher ethical standards in negotiations. (shrink)
