The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that (...) one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

The first part of this article makes the case that human cognition is an intergenerational project enabled by the inheritance and bequeathal of cognitive technology (Sects. 2–4). The final two sections of the article (Sects. 5 and 6) explore the normative significance of this claim. My case for the intergenerational claim draws results from multiple disciplines: philosophy (Sect. 2), cultural evolutionary approaches in cognitive science (Sect. 3), and developmental psychology and neuroscience (Sect. 4). In Sect. 5, I propose that cognitive (...) technology should be given to future generations in accordance with principles of pluralism and transparency. In the final main section of the article, Sect. 6, I apply these principles to topics such as the preservation of information, environmental offloading of cognition, and thinking itself. (shrink)

In the future, human destiny may depend on our ethics. In particular, biotechnology and expansion in space can transform life, raising profound questions. Guidance may be found in Life-centered ethics, as biotic ethics that value the basic patterns of organic gene/protein life, and as panbiotic ethics that always seek to expand life. These life-centered principles can be based on scientific insights into the unique place of life in nature, and the biological unity of all life. Belonging to life then implies (...) a human purpose: to safeguard and propagate life. Expansion in space will advance this purpose but will also raise basic questions. Should we expand all life or only intelligent life? Should we aim to create populations of trillions? Should we seed other solar systems? How far can we change but still preserve the human species, and life itself? The future of all life may be in our hands, and it can depend on our guiding ethics whether life will fulfil its full potentials. Given such profound powers, life-centered ethics can best secure future generations. Our descendants may then understand nature more deeply, and seek to extend life indefinitely. In that future, our human existence can find a cosmic purpose. (shrink)

A very influential idea in the epistemology of modality is that we acquire knowledge of metaphysical modality through knowledge of essence. As a consequence, the epistemology of essence becomes crucial in the attempt to answer the question of how we come to know modal propositions. In this paper I investigate Lowe’s and Hale’s approach to the epistemology of essence and argue that both of them remain in a crucial, structural sense incomplete. Systematizing this criticism against Lowe and Hale, I then (...) break down desiderata of what I call a structurally complete picture of the epistemology of essence. Finally, I discuss Husserl’s epistemology of essence and defend it against a notorious objection. However, Husserl’s approach also seems to remain incomplete, due to its appeal to imagination, which operates on the basis of background assumptions that are themselves in need of justification. I indicate, however, that a Husserlian theory of intuitive awareness of universals might supply us with (direct) justification of these background assumptions and, hence, that we might be able to paint a structurally complete picture of the epistemology of essence with Husserlian means.

nated discussion of the semantics of such verbs. I will call this view.

: The debate between proponents of ideal and non-ideal approaches to political philosophy has thus far been framed as a meta-level debate about normative theory. The argument of this essay will be that the ideal/non-ideal debate can be helpfully reframed as a ground-level debate within normative theory. Specifically, it can be understood as a debate within the applied normative field of professional ethics, with the profession being examined that of political philosophy itself. If the community of academic political theorists and (...) philosophers cannot help us navigate the problems we face in actual political life, they have not lived up to the moral demands of their vocation. A moderate form of what David Estlund decries as “utopophobia” is therefore an integral element of a proper professional ethic for political philosophers. The moderate utopophobe maintains that while devoting scarce time and resources to constructing utopias may sometimes be justifiable, it is never self-justifying. Utopianism is defensible only insofar as it can reasonably be expected to help inform or improve nonutopian political thinking. (shrink)

Solidarity is a widespread but under-explored phenomenon. In this paper, I give a philosophical account of solidarity, answering three salient questions: What motivates acts of solidarity? What unifies different acts into tokens of a single type of act, one of solidarity? And what values do acts of solidarity exhibit? The answer to all three, I argue, involves a certain way of relating to others: identifying with them on the basis of shared features, and identifying with the larger group that one (...) and the others both belong to.

A strong case can be made that the initial probability of the Resurrection is very low even if one accepts the existence of a theistic God. Even sophisticated theists who maintain that God performs miracles believe that these are rare initially improbable events. Consequently, strong evidence is needed to overcome this initial improbability. In the case of the Resurrection there is no plausible theory why this event should have occurred; moreover, even if there is, it is unlikely that it would (...) have happened at the particular time and place it did.

Here is an old philosophical puzzle. Take out a coin and look at it. It is a flat disk. Now tilt it so that you look at it on an angle. From an angle, there is some sense in which the tilted coin appears elliptical. But there is also a strong sense in which the tilted coin looks circular, like a flat disk. How can one object look both elliptical and circular at the same time? Thus, the puzzle of the (...) tilted coin. (shrink)

In my “Reply to Davis” (Philo vol. 2, no. 1) I defended two theses: First, even for Christians the initial probability of the Resurrection is very low. Second, the historical evidence for the Resurrection is not strong enough to overcome this initial improbability. Consequently, I maintained that belief in the Resurrection is not rational even for Christians. In his latest reply, “The Rationality of Resurrection for Christians: A Rejoinder” (present issue), Stephen T. Davis emphasizes that he is only defending the (...) rationality of belief in the Resurrection for Christians, not for non-Christian supernaturalists. Presumably this point is emphasized by Davis because he supposes that I have at best shown that belief in the Resurrection is not rational for non-Christian supernaturalists. However, this is not so. In this reply I will defend the two theses stated above. (shrink)

Our aim in this paper is to present the distinct ways in which Wolff, Baumgarten, and Kant understand the relationship between necessitation, constraint, and reluctant action in an effort to illustrate the subtle ways in which their conceptions of obligation differ from each another. Whereas Wolff conceives of natural or moral obligation as incompatible with constraint, Baumgarten holds that constraint and reluctant action are, in some instances, compatible with natural obligation. Kant departs from Baumgarten by conceiving of obligation as necessarily (...) involving constraint: as Kant’s reply to Schiller’s famous objection reveals, obligation must take on the character of constraint to reluctant action on account of the fact that human beings possess inclinations that always threaten to impel them in directions that oppose morality.

In my 1991 paper, AAnti-Individualism and Privileged Access,@ I argued that externalism in the philosophy of mind is incompatible with the thesis that we have privileged , nonempirical access to the contents of our own thoughts.¹ One of the most interesting responses to my argument has been that of Martin Davies (1998, 2000, and Chapter _ above) and Crispin Wright (2000 and Chapter _ above), who describe several types of cases to show that warrant for a premise does not always (...) transmit to a known deductive consequence of that premise, and who contend that this fact under-mines my argument for incompatibilism. I will try to show here that the Davies/Wright point about transmission of warrant does not adversely affect my argument. (shrink)

Whataboutism is een strategie waarbij op een beschuldiging wordt gereageerd met een wedervraag die eveneens een beschuldiging impliceert, waardoor de oorspronkelijke vraag eerder wordt ontweken dan beantwoord. Het is een effectieve methode om de aandacht te verplaatsen naar een andere situatie door een vergelijkbaar, dan wel onvergelijkbaar, contrast te bieden, waardoor de beschuldigde het eigen gedrag probeert te rechtvaardigen en verantwoordelijkheid probeert te ontlopen. Maar niet alle vormen van whataboutism impliceren echter een drogredenering, noch worden ze altijd verkeerd toegepast. Het (...) contrast dat voortkomt uit de vraag ‘what about’ kan dan een cruciale bijdrage leveren aan een situatie die een verdere kritische analyse vereist, en daarmee de geloofwaardigheid van de argumentatie versterken.

Could the concept of 'evil' apply to AI? Drawing on PF Strawson's framework of reactive attitudes, this paper argues that we can understand evil as involving agents who are neither fully inside nor fully outside our moral practices. It involves agents whose abilities and capacities are enough to make them morally responsible for their actions, but whose behaviour is far enough outside of the norms of our moral practices to be labelled 'evil'. Understood as such, the paper argues that, when (...) it comes to AI and evil, we have more to fear from semi-autonomous, hybrid agents: agents who have enough of a capacity to operate within a minimal form of human practices of participation and responsibility, yet remain partially outside of it, capable of acting from outside the parameters of ordinary interactions in certain circumstances, perhaps sometimes for reasons unknown.

In this article I argue that while an attachment to one's country is both natural and even partially justifiable, cultivating loyal patriotism in schools is untenable insofar as it conflicts with the legitimate aims of education. These aims include the epistemological competence necessary for ascertaining important truths germane to the various disciplines; the cultivation of critical thinking skills ; and developing the capacity for economic self‐reliance. I argue that loyal patriotism may result in a myopic understanding of history, an unhealthy (...) attitude of superiority relative to other cultures, and a coerced sense of attachment to one's homeland.

1. The primary evidence and motivation for externalism in the philosophy of mind is provided by the semantic facts that support direct reference theories of names, indexi- cal pronouns, and natural kind terms. But many externalists have forgotten their sem- antic roots, or so I shall contend here. I have become convinced of this by a common reaction among externalists to the main argument of my 1991 paper AAnti-Individual- ism and Privileged Access.@ In that argument, I concluded that externalism is (...) incompat- ible with the principle that we can have privileged, non-empirical knowledge of the contents of our own thoughts. The reaction in question amounts to a dismissive denial of one of my argument=s main premises. This premise, which I defended at length in the paper, is that an externalist thesis regarding a cognitive property should hold that possession of the property by a person _logically_, or _conceptually_, implies the existence of objects external to that person.

The connection between schools and society is often idealized to such an extentthat the educational system is thought to be the source of new and progressive ideas by which society makes its advances. The reality is quite different. It is the schools that reflect the ideas of society. This book seeks to investigate this issue via the work of Ivan Illich through a critical analysis of Illich’s writings.

Recently, there has been a renaissance of study on knowledge by acquaintance. One reason for this is that many writers believe acquaintance holds the key to understanding consciousness and our conscious experience of the world. For this reason, research on acquaintance has been primarily focused on perception and self-knowledge. While these questions are undoubtedly important, I believe being overly focused on these issues has prevented a defensible theory of knowledge by acquaintance from being developed. In particular, two questions have largely (...) been ignored in the literature. First, what kind of knowledge is knowledge by acquaintance? If knowledge by acquaintance is supposed to give us special epistemic access to its objects, what are the central epistemic features of it and how do they differ from other kinds of knowledge? Second, can we have knowledge by acquaintance beyond cases of perception and self-knowledge, and if so, how? In this dissertation, I answer both of these questions. In response to the first question, I argue that knowledge by acquaintance is a form of non-propositional discriminatory knowledge. Roughly, discriminatory knowledge is the exercise of a discriminatory capacity to single out a particular object from other objects of its kind. It is non-propositional because the object of the mental act of discriminating is not a proposition or truth. It is important that we understand knowledge by acquaintance in terms of discriminatory knowledge because it allows us to move beyond perceptual knowledge and self-knowledge. In this dissertation, I show how this is possible by showing that we can be acquainted with the natural numbers. This provides an answer to the second question. There is, in principle, no reason why acquaintance should only exist in sensory perception, provided we understand it in terms of discriminatory knowledge. The upshot of this is that my account of knowledge by acquaintance has a breadth and unity not often found in the acquaintance literature. (shrink)

In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the two forms of (...) dogmatism he distinguishes between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both operate on the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.

In this essay we argue for the Janus-faced nature of hope. We show that attempts to sanitise the concept of hope either by separating it conceptually from other phenomena such as wishful thinking, or, more generally, by seeking to minimise the negative aspects of hope, do not help us to understand the nature of hope and its functions as regards religion. Drawing on functional accounts of religion from Clifford Geertz and Tamas Pataki, who both—in their different ways—see the function of (...) religion in terms of its capacity to satisfy deep psychological needs, we demonstrate that religion uniquely positions itself with regard to hope’s two faces, simultaneously exploiting positive and negative aspects of hope.

The thesis that rationality consists in the straight-forward maximization of utility has not lacked critics. Typically, however, detractors reject the Humean picture of rationality upon which it seems based; they seek to emancipate reason from the tyranny of the passions. It is, then, noteworthy when an attack on this thesis comes from ‘within the ranks.’David Gauthier's paper ‘Reason and Maximization’ is just such an attack; and for this reason, among others, it is interesting. It is not successful, though. In defense (...) of this conclusion, we shall begin by relating the essentials of Gauthier's argument. Then we shall examine in some detail Gauthier's claim that the principle of straighforward max-imization fails to be self-supporting. We shall argue that Gauthier's defense of this claim is at best incomplete. Finally, we shall show that the fact that a normative principle is self-subverting or non-self-supporting does not entail that the principle is defective. (shrink)

Following Nancy Cartwright and others, I suggest that most (if not all) theories incorporate, or depend on, one or more idealizing assumptions. I then argue that such theories ought to be regimented as counterfactuals, the antecedents of which are simplifying assumptions. If this account of the logic form of theories is granted, then a serious problem arises for Bayesians concerning the prior probabilities of theories that have counterfactual form. If no such probabilities can be assigned, the the posterior probabilities will (...) be undefined, as the latter are defined in terms of the former. I argue here that the most plausible attempts to address the problem of probabilities of conditionals fail to help Bayesians, and, hence, that Bayesians are faced with a new problem. In so far as these proposed solutions fail, I argue that Bayesians must give up Bayesianism or accept the counterintuitive view that no theories that incorporate any idealizations have ever really been confirmed to any extent whatsoever. Moreover, as it appears that the latter horn of this dilemma is highly implausible, we are left with the conclusion that Bayesianism should be rejected, at least as it stands. (shrink)

The intentionality of virtually all thought that is distinctive of human beings is linguistically based and constitutively normative. As Robert Brandom claims in Making It Explicit, this normativity is best understood as having roots in social practice. But Brandom is wrong to insist that all intentionality is normative (thus denying intentionality to nonhuman, nonlinguistic animals). For even the simple social practices that ground the most primate norms presuppose robust nonnormative intentionality. Furthermore, Brandom’s appeal to perception to supplement his informal semantics (...) with a view to avoiding complete indeterminacy of linguistic meaning is either ineffective or arbitrary and unjustified unless perceptual states are recognized as having nonnormative intentional contents that go way beyond the mere differential responsiveness which he allows them.

This article is an explication and defense of Kant’s view that ‘imagination is a necessary ingredient of perception itself’ (Critique of Pure Reason, A120, fn.). Imagination comes into perception at a far more basic level than Strawson allows, and it is required for the constitution of intuitions (= sense experiences) out of sense impressions. It also plays an important part in explaining how it is possible for intuitions to have intentional contents. These functions do not involve the application of contents, (...) and I offer a schematic account of how they arise from preconceptual synthesis. (shrink)

Phenomenology offers a unique perspective on abortion that avoids the pitfalls associated with arguments from human rights, religious belief, or morality. Instead, and without negating the possibility that abortion may be justified for other reasons, it obtains reasons not to abort from the nature of agency and the commitments intrinsic to intentional action. Less formally, it says that abortion hurts because it involves killing something humans automatically identify with, and as humans we constitute ourselves just in terms of what we (...) identify with.

In this paper we argue that dissociative identity disorder (DID) is best interpreted as a causal model of a (possible) post-traumatic psychological process, as a mechanical model of an abnormal psychological condition. From this perspective we examine and criticize the evidential status of DID, and we demonstrate that there is really no good reason to believe that anyone has ever suffered from DID so understood. This is so because the proponents of DID violate basic methodological principles of good causal modeling. (...)

An education for cultural coherence tends to the child’s well-being through identity construction and maintenance. Critics charge that this sort of education will not bode well for the future autonomy of children. I will argue that culturally coherent education, provided there is no coercion, can lend itself to eventual autonomy and may assist minority children in countering the negative stereotypes and discrimination they face in the larger society. Further, I will argue that few individuals actually possess an entirely coherent identity; (...) rather, most of us possess hybrid identities that lend themselves to multiple, not necessarily conflicting allegiances.

Iemand die uiteindelijk voor de PhD-positie wordt gekozen, moet in staat zijn om alle vakjes aan te kruisen. Maar één ding is vrijwel zeker: van een promovendus die de functie aanvaardt, wordt zelden verwacht dat zij het basisidee voor het onderzoek, de opzet, de methodologie of iets anders heeft bedacht. Men hoeft alleen maar trainable te zijn. Tijdens de jaren "onder contract" zal de kandidaat immers waarschijnlijk niet worden aangemoedigd om een eigen intellectueel pad te ontwikkelen, of om een nieuwe (...) en interessante richting in het onderzoeksveld uit te stippelen. In plaats daarvan zal van de kandidaat naar alle waarschijnlijkheid worden verwacht dat zij de ideeën van de promotor napraat en vaak zelfs volledig overneemt. (shrink)

In a series of influential articles, George Bealer argues for the autonomy of philosophical knowledge on the basis that philosophically known truths must be necessary truths. The main point of his argument is that the truths investigated by the sciences are contingent truths to be discovered a posteriori by observation, while the truths of philosophy are necessary truths to be discovered a priori by intuition. The project of assimilating philosophy to the sciences is supposed to be rendered illegitimate by the (...) more or less sharp distinction in these characteristic methods and its modal basis. In this article Bealer's particular way of drawing the distinction between philosophy and science is challenged in a novel manner, and thereby philosophical naturalism is further defended. (shrink)

Torricelli elaborated the theory of ballistics as part of Galileo's theory of motion. In 1647 he had an interesting exchange of letters with G. B. Renieri, from Genoa, who complained that some experiments he had made with guns contradicted Galileo's theory. The correspondence discloses some fundamental issues of the Seventeenth century Scientific Revolution, the main one being to what extent mathematics can be applied to physics. Torricelli's view on this issue is ambivalent. He defends Galileo's kinematics as the correct description (...) of reality yet says that mathematics does not describe reality. It is suggested that this ambivalence is an outcome of the climate of uncertainty which followed Galileo's trial. (shrink)

According to the propositional view of belief, a belief situation involves a believer’s standing in the relation of belief to a proposition. It is argued that the propositional view has unacceptable implications concerning the identity conditions of belief situations involving beliefs with indexical contents, especially where such beliefs are held over a period of time during which background circumstances change. After a critical discussion of Perry’s alternative to the propositional view, a version of the adverbial theory of belief, which accounts (...) satisfactorily for the identity conditions of belief situations, is advanced. This theory, which avoids the standard objections to adverbialism, is defended against the charge that it cannot provide an account of the semantics of sentences attributing the same belief to two or more believers. In the course of this defense it is argued that the standard propositional account of such sentences is insensitive to everyday language. (shrink)

If something could boast of the ancient Greek world for its contribution to this global culture should be the development of philosophical thought. The search for "laws", i.e. the rules governing the nature and binding together, shifted the centre of human thought from the man himself, in the world, in the universe. His search starts with the pre-Socratic philosophical schools and reaches its peak, with the two main proponents of ancient intellect, Plato first and Aristotle's pupil. The contribution of Aristotle (...) particularly could be focused on the attempt to answer the problem of truth. For Aristotle, the search for truth sits in this thing and the intellectual space and the subjective judgment based on reasoning and evidence. Even the metaphysical thought of Aristotle, about God's problem, recommends the apotheosis of reason. The existence of God is a rational truth, it is the reason, and the truth because it fits with the being, the thing. The thought of Aristotle about the existence of God is identified with the existence of God, therefore God exists and proving that it exists. The mind can match things and establish the truth of the existence of God. In this rational metaphysics Aristotelian awareness of the existence of God, in which God, according to Aristotle, moves all other beings, but he remains motionless because it is not material and therefore not have the need of movement, at rival of the Christian philosophy. The Christian philosophy puts the concept of the person, so selfishness and diversity as a means of approach to God through the process of experience. Which is the common point between Aristotle and Christian Philosophy. In their attempt to investigate the relationship of being concerning the ontological beings and the reflection on the Being.

Guest Editor's Introduction to a special issue of the Journal of Scottish Philosophy exploring 'New Perspectives on Hutcheson's Moral Philosophy'. The purpose of the special issue is to explore aspects of Hutcheson’s moral philosophy that have not received a great deal of attention in the past and to thereby illustrate that his contributions to the history of ethics are far richer than the current secondary literature suggests.

In this article, I make a philosophical case for the state to fund religious schools. Ultimately, I shall argue that the state has an obligation to fund and provide oversight of all schools irrespective of their religious or non-religious character. The education of children is in the public interest and therefore the state must assume its responsibility to its future citizens to ensure that they receive a quality education. Still, while both religious schools and the polity have much to be (...) gained from direct funding, I will show that parents and administrators of these schools may have reasons to be diffident toward the state and its hypothetical interference. While the focus of the paper is primarily on the American educational context, the philosophical questions related to state funding and oversight of religious schools transcend any one national context .

In this article, we reconsider the syntactical analysis as well as the categorial status of two Medieval French elements, et and ne. In this connection, we illustrate and compare various approaches which principally differ with regard to the assignment of a unique category or of various categories to these elements.
