The Value of Trees project, funded bythe International Development Research Council ofCanada (IDRC), supported the joint efforts of theUniversity of Alberta and the University of Zimbabweto investigate the economic costs and benefitsassociated with trees and forests in the small holderfarming sector in Zimbabwe. The Value of Trees project provided funding for graduate students andfaculty from the two participating universities tocarry out studies in the disciplines of forestry,agricultural economics, and sociology in order toprovide policy recommendations regarding the role ofwoodlands in sustainable (...) small holder farming in acontext where agricultural production appears to putincreasing stress on woodlands. The numerous projectsincluded such topics as the following: the use offuelwood under conditions of scarcity, tree tenure andlocal institutions in woodland use and sustainability,gender and wealth as related to tree planting andconservation, time preferences in natural resourceconsumption, ownership and economic impact ofeucalyptus woodlots, cultural and economic valuesassociated with woodlands, and uses and conflictsrelating to woodlands across different land categoriessuch as resettlement land and state forests. Manyother studies were not funded by, but were associatedwith Value of Trees. The findings fall withintwo broad categories. The first set includes thosedirectly related to generating values for differentaspects of the woodlands, particularly from theperspectives of rural households. The main finding isthat despite being highly valued by local people forboth economic and social reasons, woodlands are rankedlower in importance by local farmers than agriculturalland. The second set of findings relates to thecomplexities of the social system of the woodlands.Local institutions, history, resource conflicts, andtenure issues emerge as key to understanding the waythat people interact with the woodlands. Finally,local people have valuable knowledge and strategies tooffer in the design of sustainable management. Thepolicy implications of these findings for Zimbabwe arethat economic incentives could be important in asustainable woodlands strategy, but that anysuccessful program must incorporate an understandingof the profoundly complex and at times contradictoryhuman dynamics of woodland use and values.

Billy Dunaway develops and defends a framework for realism about morality. He defends the idea that moral properties are privileged parts of reality which are the referents for our moral terms. He suggests how it is that we can know about morality, and what the limits to moral disagreement are.

This new study provides a refreshing look at the issue of exceptions and shows that much of the problem stems from a failure to recognize at least two kinds of exception-ridden law: ceteris paribus laws and ideal laws. Billy Wheeler offers the first book-length discussion of ideal laws. The key difference between these two kinds of laws concerns the nature of the conditions that need to be satisfied and their epistemological role in the law’s formulation and discovery. He presents (...) a Humean-inspired approach that draws heavily on concepts from the information and computing sciences. Specifically, Wheeler argues that laws are best seen as algorithms for compressing empirical data and that ideal laws are needed as 'lossy compressors' for complex data. Major figures in the metaphysics of science receive special attention such as Ronald Giere, Bas van Fraassen, Nancy Cartwright, David Lewis and Marc Lange. This book is essential reading for philosophers of science and will interest metaphysicians, epistemologists and others interested in applying concepts from computing to traditional philosophical problems.

This paper is about avoiding commitment to an ontology of possible worlds with two primitives: a hyperintensional connective like ‘in virtue of’, and primitive quantification into predicate position. I argue that these tools (which some believe can be independently motivated) render dispensable the ontology of possible worlds needed by traditional anaylses of modality. They also shed new light on the notion of truth-at-a-world.

La originalidad de Blanchot en el ámbito de las críticas deconstructivas al tema de la propiedad/impropiedad de la muerte en la obra de Heidegger no ha recibido demasiada atención de los comentaristas. A tal fin, examino la noción de muerte en la obra de R. M. Rilke, para después recorrer el abordaje que de esta temática realizó Blanchot en El espacio literario . Luego, relevando las líneas de fuerza de la lectura blanchotiana, se pondrá de manifiesto hasta qué punto el (...) pensamiento de Rilke puede constituir una herramienta para deconstruir cierto resto de subjetividad moderna en la noción de muerte heideggeriana.

It is often said that the best system account of laws needs supplementing with a theory of perfectly natural properties. The ‘strength’ and ‘simplicity’ of a system is language-relative and without a fixed vocabulary it is impossible to compare rival systems. Recently a number of philosophers have attempted to reformulate the BSA in an effort to avoid commitment to natural properties. I assess these proposals and argue that they are problematic as they stand. Nonetheless, I agree with their aim, and (...) show that if simplicity is interpreted as ‘compression’, algorithmic information theory provides a framework for system comparison without the need for natural properties.

We are becoming increasingly dependent on robots and other forms of artificial intelligence for our beliefs. But how should the knowledge gained from the “say-so” of a robot be classified? Should it be understood as testimonial knowledge, similar to knowledge gained in conversation with another person? Or should it be understood as a form of instrument-based knowledge, such as that gained from a calculator or a sundial? There is more at stake here than terminology, for how we treat objects as (...) sources of knowledge often has important social and legal consequences. In this paper, I argue that at least some robots are capable of testimony. I make my argument by exploring the differences between instruments and testifiers on a well-known account of knowledge: reliabilism. On this approach, I claim that the difference between instruments and testifiers as sources of knowledge is that only the latter are capable of deception. As some robots can be designed to deceive, so they too should be recognized as testimonial sources of knowledge. (shrink)

This essay examines whether or not absurdity is intrinsic to human life. It takes Camus’ interpretation of ‘The Absurd’ as its conceptual starting point. It traces such thought back to Schopenhauer, whose work is then critically analysed. This analysis focuses primarily on happiness and meaning. This essay accepts some of Schopenhauer’s premises, but rejects his conclusions. Instead, it considers Nietzsche’s alternatives and the role of suffering in life. It posits that suffering may help people acquire meaning and escape absurdity. It (...) then analyses the role of compassion in absurdity, in reference to Nietzsche’s work and Buddhist teachings. Lastly, it examines absurdity in relation to death, rejecting the notion that death exacerbates absurdity. This paper understands absurdity to be a natural part of the human condition, as characterised by suffering, death and an absence of meaning. It concludes that although human life is absurd by nature, it need not remain so. (shrink)

This book gives an account of a full spectrum of property rights and their relationship to individual liberty. It shows that a purely deontological approach to justice can deal with the most complex questions regarding the property system. Moreover, the author considers the economic, ecological, and technological complexities of our real-world property systems. The result is a more conceptually sound account of natural rights and the property system they demand. If we think that liberty should be at the centre of (...) justice, what does that mean for the property system? Economists and lawyers widely agree that a property system must be composed of many different types of property: the kind of private ownership one has over one's person and immediate possessions, as well as the kinds of common ownership we each have in our local streets, as well as many more. However, theories of property and justice have not given anything approaching an adequate account of the relationship between liberty and any other form of property other than private ownership. It is often thought that a basic commitment to liberty cannot really tell us how to arrange the major complexities of the property system, which diverge from simple private ownership. Property and Justice demonstrates how philosophical rigour coupled with interdisciplinary engagement enables us to think clearly about how to deal with real-world problems. It will be of interest to political philosophers, political theorists, and legal theorists working on property rights and justice. (shrink)

Providing an antidote to our culture's never-ending quest for more, mindfulness teacher Billy Wynne shows how embracing the Buddhist concept of emptiness can declutter the mind and distill our experience of daily life to its essential beauty, clarity, and joy.

The scope of libertarian law is normally limited to the application of the non-aggression principle (NAP), nothing more and nothing less. However, judging when the NAP has been violated requires not only a conception of praxeological notions such as aggression, but also interpretive understanding of what synthetic events count as the relevant praxeological types. Interpretive understanding—or verstehen—can be extremely heterogeneous between agents. The particular verständnis taken by a judge has considerable moral and political implications. Since selecting a verständnis is pre-requisite (...) to applying the NAP, the NAP itself cannot tell us which one we ought morally to choose. Therefore the application of the NAP calls on moral and political considerations outside of the NAP itself. Since some of these are more consistent with an endorsement of the NAP than others, libertarianism is not a “thin” commitment to the NAP alone, but a “thick” commitment to the NAP and other supporting moral and political considerations.

To what extent are the answers to theological questions knowable? And if the relevant answers are knowable, which sorts of inquirers are in a position to know them? In this chapter we shall not answer these questions directly but instead supply a range of tools that may help us make progress here. The tools consist of plausible structural constraints on knowledge. After articulating them, we shall go on to indicate some ways in which they interact with theological scepticism. In some (...) cases the structural constraints bear directly on whether one can know answers to theological questions. But the structural considerations are related to theological scepticism in other interesting ways as well; for instance we will also be using them to explore the significance of scepticism, by addressing questions such as ‘To what extent does it matter whether or not we can know the answer to theological questions?’.

Humans are becoming increasingly dependent on the ‘say-so' of machines, such as computers, smartphones, and robots. In epistemology, knowledge based on what you have been told is called ‘testimony' and being able to give and receive testimony is a prerequisite for engaging in many social roles. Should robots and other autonomous intelligent machines be considered epistemic testifiers akin to those of humans? This chapter attempts to answer this question as well as explore the implications of robot testimony for the criminal (...) justice system. Few are in agreement as to the ‘types' of agents that can provide testimony. The chapter surveys three well-known approaches and shows that on two of these approaches being able to provide testimony is bound up with the possession of intentional mental states. Through a discussion of computational and folk-psychological approaches to intentionality, it is argued that a good case can be made for robots fulfilling all three definitions. (shrink)

Lockean approaches to property take it that persons can unilaterally acquire private ownership over hitherto unowned resources. Such natural law accounts of property rights are often thought to be of limited use when dealing with the complexities of natural resource use outside of the paradigm of private ownership of land for agricultural or residential development. The tragedy of the commons has been shown to be anything but an inevitability, and yet Lockeanism seems to demand that even the most robust common (...) property arrangements be converted to privatized units. This often motivates a move away from natural law in the moral analysis of property rights. I argue however that it is not the deontological nature of Lockean principles that are at fault, but rather the manner of their application. Lockean theory often exhibits a bias in favour of private property: assuming that only private property can protect one’s interest in autonomy, and therefore asserting that each individual has a power of private acquisition. Starting with a claim against interference however enables us to mould the appropriate property rights to each individual’s particular interest in autonomy. This sometimes leads to private ownership, but often leads to various forms of commons. (shrink)

Over the centuries the term “talent” has changed semantically and slowly transformed itself into a floating signifier or become an accidental designator. The term “talent” no longer has one single meaning and a “referent” in real life, but instead a multiplicity of meaning and references to something beyond real life, something indefinite and indefinable. In other words, today we do not know specifically what the term “talent” in talent management really means or refers to. Indeed, this is problematical, because in (...) late modernity the term “talent” has become a popular and frequently used key term among business consultants and, within the science of human resource management, a cornerstone in the discipline of “talent management”, and not knowing what the term really means will turn any talent discussion, talent identification and talent recruitment into a question of subjectivity and belief in talent rather than objectivity and knowledge of talent.

Adriaan Peperzak’s knowledge of the history of philosophy and his Continental philosophical nexus gives his Before Ethics a unique and welcome flavor. In eight essays on contemporary ethics written between 1969 and 1997, Peperzak analyzes our utilitarian, Kantian-deontological, and virtue-oriented ethical convictions in a thorough and enlightening manner.

This paper looks at the phenomenon of ethical vagueness by asking the question, how ought one to reason about what to do when confronted with a case of ethical vagueness? I begin by arguing that we must confront this question, since ethical vagueness is inescapable. I then outline one attractive answer to the question: we ought to maximize expected moral value when confronted with ethical vagueness. This idea yields determinate results for what one rationally ought to do in cases of (...) ethical vagueness. But what it recommends is dependent on which substantive theory of vagueness is true; one can't draw conclusions about how to reason about vagueness in ethics in the absence of concrete assumptions about the nature of vagueness.

Informational structural realism (ISR) offers a new way to understand the nature of the “structure” that structural realists claim our best scientific theories get right about the world. According to Luciano Floridi, who has given the most detailed formulation of ISR so far, this structure is composed of information representing binary differences. In this paper I assess whether ISR offers a good way to resolve the tension between the no miracle argument (often taken to support scientific realism) and the pessimistic (...) meta-induction (often taken to support antirealism). With regards to this important motivation for structural realism, I shall argue that ISR faces insurmountable difficulties. However, I agree that interpreting “structure” in terms of information can be profitable for the realist. Instead, I offer a new version of ISR that borrows from algorithmic information theory. As a result, a more realist version of ISR is provided. (shrink)

Objects appear to causally interact with one another in virtual worlds, such as video games, virtual reality, and training simulations. Is this causation real or is it illusory? In this paper I argue that virtual causation is as real as physical causation. I achieve this in two steps: firstly, I show how virtual causation has all the important hallmarks of relations that are causal, as opposed to merely accidental, and secondly, I show how virtual causation is genuine according to one (...) influential metaphysical theory of causation: the mechanistic approach.

It has been argued that the fundamental laws of physics do not face a ‘problem of provisos’ equivalent to that found in other scientific disciplines (Earman, Roberts and Smith 2002) and there is only the appearance of exceptions to physical laws if they are confused with differential equations of evolution type (Smith 2002). In this paper I argue that even if this is true, fundamental laws in physics still pose a major challenge to standard Humean approaches to lawhood, as they (...) are not in any obvious sense about regularities in behaviour. A Humean approach to physical laws with exceptions is possible, however, if we adopt a view of laws that takes them to be the algorithms in the algorithmic compressions of empirical data. When this is supplemented with a distinction between lossy and lossless compression, we can explain exceptions in terms of compression artefacts present in the application of the lossy laws.

This article intervenes into contemporary scholarship on affect by bringing different affect theories into the same analytical frame. Analysing commercial surrogacy in India through three different conceptualizations of affect found in the work of Michael Hardt, Sara Ahmed and Brian Massumi reveals how affect emerges as a malleable state in the practice of, as a circulatory force in the debates around, and as an ephemeral intensity in the spontaneous resistance to surrogacy. Based on this analysis, I suggest that integrating different (...) theories of affect enables more holistic examinations of corporeal regulation by opening our understanding to the multiple lives of affect that operate on the level of political economy, cultural signification and material intensity simultaneously.

Hillel Steiner argues that a necessary and sufficient condition for the compossibility of a set of rights is that those rights be extensionally differentiable. However, given that two or more actions can extensionally overlap without thereby being mutually unperformable, if such actions are specified in the relevant rights, then those rights will not be incompossible, notwithstanding their extensional overlap. The set of compossible sets of rights then is greater than the subset of extensionally differentiable rights, and extensional differentiability is a (...) sufficient but unnecessary condition of compossibility.

Computer models and simulations have provided enormous benefits to researchers in the natural and social sciences, as well as many areas of philosophy. However, to date, there has been little attempt to use computer models in the development and evaluation of metaphysical theories. This is a shame, as there are good reasons for believing that metaphysics could benefit just as much from this practice as other disciplines. In this paper I assess the possibilities and limitations of using computer models in (...) metaphysics. I outline the way in which different kinds of model could be useful for different areas of metaphysics, and I illustrate in more detail how agent-based models specifically could be used to model two well-known theories of laws: David Lewis’s "Best System Account" and David Armstrong's "Nomic Necessitation" view. Some logically possible processes cannot be simulated on a standard computing device. I finish by assessing how much of a threat this is to the prospect of metaphysical modeling in general. (shrink)

Across career development and academic advising literature, scholars describe a common and unsettling tension between when to challenge and support students’ goals. Many programs of study include selective admission or gateway prerequisite courses. Students may also need to modify their goals while pursuing competitive employment or graduate school programs. As career professionals and academic advisors begin to perceive that students may not be able to achieve their aspirations, they may discuss different pathways and alternative careers. Some academic advisors use predictive (...) analytics to identify students who may not progress within their chosen degree program, which further compounds the ethical dilemma. If practitioners do not engage in ethical inquiry and deliver feedback carefully, some students could experience distress or pivot away from their goals unnecessarily. As they discuss career alternatives, practitioners can consider the integrated literature review included in this article. Practitioners can use scholars’ different frameworks and thematic recommendations to bring equity and ethical integrity to their career conversations. (shrink)

RESUMEN En el marco de las concepciones compensatorias de la naturaleza humana, la negatividad asignada a lo humano se «dialectiza». A partir de dicha constatación, señalaremos las dificultades que ello implica en el abordaje de las cuestiones actuales en torno al hombre. Evidenciaremos la importancia de renovar la noción de «ausencia de naturaleza» que circula en cierta línea alemana de problematización de lo humano, de la cual la noción de «pobreza» postulada por Heidegger constituirá el exemplum. Valiéndome de la interpretación (...) de la «pobreza» realizada por M. Blanchot, indicaré la posibilidad de leer la ausencia de naturaleza no en tanto pura negatividad sino como pasividad no dialectizable que afecta al hombre.PALABRAS CLAVE POBREZA, PASIVIDAD, BLANCHOT, HEIDEGGER, ESPOSITOABSTRACT Human negativity is “dialectized” within the framework of the compensatory conceptions of Human Nature. After analysing this point, we will call attention to the difficulties it implies when approaching the contemporary questions around the Human Being. We will demonstrate the importance of renewing the notion of ‘absence of nature’ that circulates in a certain German line of research on the human, of which the notion of ‘poverty’ postulated by Heidegger will constitute the exemplum. Making use of the interpretation of “poverty” made by M.

Quasi-realist Expressivists offer accounts of normative truth, normative facts, and normative properties which make their view apparently indistinguishable from Realist views on these subjects. This chapter explores the idea that there is still a substantial metaphysical difference between Realism and Quasi-realism, since they differ over the extent to which normative properties are metaphysically elite in David Lewis’s sense. Eliteness is an explanatory notion, and Realists need the explanatory features of eliteness to explain how different communities refer to the same property (...) with their word “ought.” While Quasi-realists can agree with Realists about which property “ought” refers to, the same resources they use to explain normative truth, reference, and facthood also explain why the referential facts are this way. Thus eliteness does not enter the explanatory picture for the Quasi-realist, and the metaphysics of obligation looks very different on the Realist and Quasi-realist views. (shrink)

Is it possible to gain knowledge about the real world based solely on experiences in virtual reality? According to one influential theory of knowledge, you cannot. Robert Nozick's truth-tracking theory requires that, in addition to a belief being true, it must also be sensitive to the truth. Yet beliefs formed in virtual reality are not sensitive: in the nearest possible world where P is false, you would have continued to believe that P. This is problematic because there is increasing awareness (...) from philosophers and technologists that virtual reality is an important way in which we can arrive at beliefs and knowledge about the world. Here I argue that a suitably modified version of Nozick's sensitivity condition is able to account for knowledge from virtual reality. (shrink)

It is not an exaggeration to say that Allan Gibbard is one of the most significant contributors to philosophy over the last five decades. Gibbard's work covers an impressive number of subfields within philosophy, including ethics, philosophy of language, decision theory, epistemology, and metaphysics. It also engages with, and makes significant contributions to, work from the natural and social sciences. This volume is not a collection of artifacts from past decades of philosophy. Instead, it is a collection of essays that (...) each make a significant contribution to contemporary work in philosophy. This reflects the fact that Gibbard's work has not only had a massive influence on past discussion in philosophy but also continues to influence new directions of philosophical research.

Many libertarians ground their theory of justice in a non-aggression principle. The NAP is often the basis for the libertarian condemnation of state action – that it is necessarily aggressive and therefore unjust. This approach is often criticised insofar as it defines aggression, in part, as the violation of legitimate property rights, and is therefore parasitical upon a prior – and unjustified – theory of property. While it is true that libertarians who defend the NAP sometimes fail to give a (...) satisfactory account of its relationship to libertarian property rights, such an account is in fact available. A commitment to property rights and to non-aggression can both be grounded in a commitment to non-interference. Such a principle, then, brings together the NAP and the theory of property it is parasitical upon, thus saving the unity and austerity of the overall approach. (shrink)
