It is generally agreed that one origin of machine bias is resulting from characteristics within the dataset on which the algorithms are trained, i.e., the data does not warrant a generalized inference. We, however, hypothesize that a different ‘mechanism’ may also be responsible for machine bias, namely that biases may originate from the programmers’ cultural background, including education or line of work, or the contextual programming environment, including software requirements or developer tools. Combining an experimental and comparative design, we study (...) the effects of cultural and contextual metaphors, and test whether each of these are ‘transferred’ from the programmer to the program, thus constituting a machine bias. Our results show that cultural metaphors influence the programmer’s choices and contextual metaphors induced through priming can be used to moderate or exacerbate the effects of the cultural metaphors. Our studies are purposely performed with users of varying educational backgrounds and programming skills stretching from novice to proficient. (shrink)

Thomas Kjeller Johansen presents a new account of Aristotle's major work on psychology, the De Anima.

Mathematicians’ use of external representations, such as symbols and diagrams, constitutes an important focal point in current philosophical attempts to understand mathematical practice. In this paper, we add to this understanding by presenting and analyzing how research mathematicians use and interact with external representations. The empirical basis of the article consists of a qualitative interview study we conducted with active research mathematicians. In our analysis of the empirical material, we primarily used the empirically based frameworks provided by distributed cognition and (...) cognitive semantics as well as the broader theory of cognitive integration as an analytical lens. We conclude that research mathematicians engage in generative feedback loops with material representations, that they use representations to facilitate the use of experiences of handling the physical world as a resource in mathematical work, and that their use of representations is socially sanctioned and enabled. These results verify the validity of the cognitive frameworks used as the basis for our analysis, but also show the need for augmentation and revision. Especially, we conclude that the social and cultural context cannot be excluded from cognitive analysis of mathematicians’ use of external representations. Rather, representations are socially sanctioned and enabled in an enculturation process. (shrink)

Plato's dialogue the Timaeus-Critias presents two connected accounts, that of the story of Atlantis and its defeat by ancient Athens and that of the creation of the cosmos by a divine craftsman. This book offers a unified reading of the dialogue. It tackles a wide range of interpretative and philosophical issues. Topics discussed include the function of the famous Atlantis story, the notion of cosmology as 'myth' and as 'likely', and the role of God in Platonic cosmology. Other areas commented (...) upon are Plato's concepts of 'necessity' and 'teleology', the nature of the 'receptacle', the relationship between the soul and the body, the use of perception in cosmology, and the work's peculiar monologue form. The unifying theme is teleology: Plato's attempt to show the cosmos to be organised for the good. A central lesson which emerges is that the Timaeus is closer to Aristotle's physics than previously thought. (shrink)

Judgementalism is an interpretation of normative decision theory according to which preferences are all-things-considered judgements of relative desirability, and the only attitudes that rationally constrain choice. The defence of judgementalism we find in Richard Bradley’s Decision Theory with a Human Face relies on a kind of internalism about the requirements of rationality, according to which they supervene on an agent’s mental states, and in particular those she can reason from. I argue that even if we grant such internalism, attitudes other (...) than preferences in the judgementalist sense rationally constrain choice. This ultimately supports a different interpretation of preference. (shrink)

This article analyses and discusses dilemmas, ambivalences and problematic issues related to research ethics. This is done firstly by making a distinction between procedural research ethics and particularistic research ethics. Such a distinction reflects a theoretical construction and generalization. In practice, there can be a very close correlation between the two types. In the following, the distinction will therefore be used as a starting point for the presentation of a pragmatic-dualist research ethics. The approach is dualist because it draws on (...) the presence of two independent, contrasting understandings, which are essentially different yet equal aspects of good research ethics; it is pragmatic because this dualism is structural and institutional by nature, and designed with an eye to what can realistically and expediently be done in practice. Thus the intention of the article is to both analyze and discuss two different understandings of research ethics and simultaneously qualify a research ethics that draws on both of these understandings. Furthermore, the intention is to visualize a different understanding of research ethics which others can address and elaborate on or qualify. Even at this point, this research ethic can be included in a catalogue of understandings of ethical research practice an can be exploited in ethical research practice. (shrink)

Aristotle thinks that an account, alogos, of some sort is characteristic of craft,technē. Some scholars think that thelogoselement oftechnēis tagged onto experience as a theoretical element not directly engaged in successful production: I argue instead that thelogosgrounds the productive ability of craft, and also that is practically orientated in a way that distinguishes it from thelogosof theoretical science. Understanding thelogosof craft thus helps us explain how the craftsman differs both from the merely experienced practitioner and from the theoretical scientist.

This paper investigates the notion of semiotic scaffolding in relation to mathematics by considering its influence on mathematical activities, and on the evolution of mathematics as a research field. We will do this by analyzing the role different representational forms play in mathematical cognition, and more broadly on mathematical activities. In the main part of the paper, we will present and analyze three different cases. For the first case, we investigate the semiotic scaffolding involved in pencil and paper multiplication. For (...) the second case, we investigate how the development of new representational forms influenced the development of the theory of exponentiation. For the third case, we analyze the connection between the development of commutative diagrams and the development of both algebraic topology and category theory. Our main conclusions are that semiotic scaffolding indeed plays a role in both mathematical cognition and in the development of mathematics itself, but mathematical cognition cannot itself be reduced to the use of semiotic scaffolding.

The article shows that Michel Foucault's account of the sexual body is not a naive return to a prediscursive body, nor does it amount to discourse reductionism and to the exclusion of experience, as some feminists have argued. Instead, Foucault's idea of bodies and pleasures as a possibility of the counterattack against normalizing power presupposes an experiential understanding of the body. The experiential body can become a locus of resistance because it is the possibility of an unpredictable event.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Globalizing Music Education. A Framework by Alexandra Kertz-WelzelGeir JohansenAlexandra Kertz-Welzel, Globalizing Music Education. A Framework (Bloomington: Indiana University Press, 2018)A recurring challenge for the scholarship of music education is that, in a time of information overflow, we still miss significant knowledge about each other’s work, disseminated across national and cultural borders. However, as such challenges are situated within larger, more general frames of cultural as well as political (...) forces and powers, we need systematic approaches to handling them, based on international and global perspectives.Alexandra Kertz-Welzel’s book Globalizing Music Education constitutes an excellent ground for such work. Her purpose is to provide a conceptual framework, entailing “a theoretical structure of categories and conceptual elements that can facilitate becoming a united and diverse global music education community”1 which is “culturally sensitive.”2 She constructs the framework by introducing its conceptual elements along with unfolding the argument within each chapter. For some readers, it might have been easier to achieve the framework structure if described explicitly, for example in a model. For others, it may be exciting to explore it gradually together with the author as she develops her narrative.Kertz-Welzel intends the book to be a guide “for people’s own scholarly journeys, as well as for the profession.”3 As her point of departure, she takes a [End Page 97] comprehensive perspective, drawing the readers’ attention to how “[g]lobalization and internationalization have shaped our lives in ways that we do not notice anymore.”4 Pointing to a variety of non-musical as well as musical examples and relating her overview to social anthropologist Thomas Hylland Eriksen’s5 eight dimensions of globalization, she demonstrates her comprehensive knowledge of relevant information within other fields along with the ability to utilize it in order to enrich her analyses. This attention to other fields represents a recurring trait within the book, significantly increasing its quality.Modestly and realistically, she states that the book “can only be a first attempt to start a professional discourse about the impact globalization and internationalization have on music education worldwide....”6 Here, one might be confused about whether ‘discourse’ points to ‘discussion’ or discourse theory,7 but the latter perspective is brought in more clearly as she moves along. Secondly, the attention towards ‘impact,’ occurring several times throughout the book, raises a question about the balance between a focus on coping with the consequences of globalization and emphasizing our agency in these matters. Bringing in the latter by statements such as “[w]e are actors, not victims”8 and increasing this balance when discussing policy in Chapter Three, Kertz-Welzel’s argument still reveals a potential for further discussion. Moreover, addressing the challenges of globalization, we need to “help [students] develop different kinds of musicianship connected to their personal music identities,”9 she holds. Again, a potential for further discussion emerges, this time about the weight on the personal and individual over the collective. This issue might be an interesting one to discuss further within a globalized music education community.What is globalizing music education about, then? A condensed version of Kertz-Welzel’s argument might include addressing the challenges we face today by uniting our efforts and using the multi-faceted strengths we have, across the globe, in order to arrive at a united yet diverse and culturally sensitive global music education community.The main body of the book contains three chapters. In Chapter One, Kertz-Welzel distinguishes between internationalization and globalization by connecting ‘international’ with relations between nations and national organizations, while globalization rests within a notion of a worldwide community, representing a new unity based on global visions and interests, constantly transformed and in search of its identity. “This notion of globalizing can concern areas such as music education,”10 she suggests. The chapter addresses the impact globalization and internationalization have on education, music, and language, making those concepts constitute cornerstones of the suggested framework.Addressing education, Kertz-Welzel holds that globalization and internationalization have changed education from being a clearly national endeavor [End Page 98] rooted in distinctive, national values and traditions to becoming a cultural project of the world society...

Scholars have often seen Parmenides as entirely opposed to earlier materialistic philosophy. In this paper I argue that what is more striking in Aristotle’s Metaphysics Book I is the degree of continuity that he sees between Parmenides and the material monists. I explore this coupling of Parmenides with the material monists to understand better what he takes to be distinctive and problematic with Parmenides’ monism.

This article takes stock of the regularity theory of causation. It considers three challenges to the theory: the problem of joint effects, the problems of redundant causation, and omission‐involving causation. The former is often cited as a special, and especially challenging, problem for regularity theories. But the force of this problem has been greatly overstated. The threat to regularity theories instead comes from the latter two.

This book discusses key philosophical concepts and ideologies, including ontology, epistemology, logic, semantics, moral and political philosophy, theology and aesthetics during classical antiquity. Karsten Friis Johansen charts the history of ancient philosophy from the mythological oral tradition, Homer and early tragedy, to the giants of Plato and Aristotle through to paganism and the genesis of Christianity. A History of Ancient Philosophy also presents detailed analysis of individual ancient philosophers and interpretations and commentary on key philosophical passages.

We show that every countable ideal of degrees that are low for isomorphism is contained in a principal ideal of degrees that are low for isomorphism by adapting an exact pair construction. We further show that within the hyperimmune free degrees, lowness for isomorphism is entirely independent of computable traceability.

This article examines a social accounting cycle in a Danish savings bank with specific focus on how employees interacted with the cycle. The case study is based on archival material and observations of employee engagement sessions that were a significant part of the cycle. The article exposes the ways in which the cycle can be understood as an initiative that prompts different forms of accountability. The cycle had the potential to bring different forms of accountability together, but the cycle also (...) faced challenges that threatened its relevance from an employee perspective. These challenges might have implications for the way we perceive social accounting and the role of employees. (shrink)

Background Moral courage means courage to act according to individual’s own ethical values and principles despite the risk of negative consequences for them. Research about the moral courage of whistle-blowers in health care is scarce, although whistleblowing involves a significant risk for the whistle-blower. Objective To analyse the moral courage of potential whistle-blowers and its association with their background variables in health care. Research design Was a descriptive-correlational study using a questionnaire, containing Nurses Moral Courage Scale©, a video vignette of (...) the wrongdoing situation with an open question about the vignette, and several background variables. Data were analysed statistically and inductive content analysis was used for the narratives. Participants and research context Nurses as healthcare professionals (including registered nurses, public health nurses, midwives, and nurse paramedics) were recruited from the membership register of the Nurses’ Association via email in 2019. A total of 454 nurses responded. The research context was simulated using a vignette. Ethical considerations Good scientific inquiry guidelines were followed. Permission to use the Nurses’ Moral Courage Scale© was obtained from the copyright holder. The ethical approval and permission to conduct the study were obtained from the participating university and the Nurses’ Association. Findings The mean value of potential whistle-blowers’ moral courage on a Visual Analogue Scale (0–10) was 8.55 and the mean score was 4.34 on a 5-point Likert scale. Potential whistle-blowers’ moral courage was associated with their socio-demographics, education, work, personality and social responsibility related background variables. Discussion and conclusion In health care, potential whistle-blowers seem to be quite morally courageous actors. The results offer opportunities for developing interventions, practices and education to support and encourage healthcare professionals in their whistleblowing. Research is needed for developing a theoretical construction to eventually increase whistleblowing and decrease and prevent wrongdoing. (shrink)

The paper traces, historically and systematically, the influence of Carnap’s philosophical program on the writings of Nelson Goodman, focusing on the relationship between Carnap’s Aufbau and Goodman’s Structure of Appearance. In particular, drawing on unpublished material from the Carnap Research Archives, I show that Carnap had already anticipated Goodman’s criticism of the method of quasi-analysis and that Goodman misconstrued the status of this procedure on several counts. I also argue that Carnap’s anti-metaphysical stance left his approach with an explanatory deficit (...) which Goodman’s pragmatist pluralism is able to address. (shrink)

In 'How Should We Aggregate Competing Claims', Alex Voorhoeve suggests accommodating intuitions about duties in rescue cases by combining aggregative and non-aggregative elements into one theory. In this paper, I discuss two problems Voorhoeve’s theory faces as a result of requiring a cyclic pattern of choice, and argue that his attempt to solve them does not succeed.

In her book, Oksala shows that the arguments for the ineliminability of violence from the political are often based on excessively broad, ontological conceptions of violence distinct from its concrete and physical meaning and, on the other hand, on a restrictively narrow and empirical understanding of politics as the realm of conventional political institutions.

Some scientists are happy to follow in the footsteps of others; some like to explore novel approaches. It is tempting to think that herein lies an epistemic division of labor conducive to overall scientific progress: the latter point the way to fruitful areas of research, and the former more fully explore those areas. Weisberg and Muldoon’s model, however, suggests that it would be best if all scientists explored novel approaches. I argue that this is due to implausible modeling choices, and (...) I present an alternative ‘epistemic landscape’ model that demonstrates the alleged benefits from division of labor, with one restriction. (shrink)

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

Acknowledgments I wish to express my gratitude to Dr. Jakob Amstutz for his continual feedback during my writing of this work. ...

Regularity theories of causation are guided by the idea that causes are collectively sufficient for their effects. Following Mackie [1974], that idea is typically refined to distinguish collections that include redundant members from those that do not. Causes must be collectively sufficient for their effects without redundancy. While Mackie was surely right that the regularity theory must distinguish collections that are in some sense minimally sufficient for an effect from those that include unnecessary hangers-on, I believe that redundancy is the (...) wrong mark of that distinction. I propose a way to develop the regularity theory without it. Instead of distinguishing minimal from mere sufficiency in terms of redundancy, we should look to the influence that events have in the world. Causes, so construed, must have just enough collective influence to ensure that an effect occurs. I argue that such an account provides a uniform solution to the problem of epiphenomena and to a pair of related problems that aris.. (shrink)

This chapter engages with Roger Cotterrell's characterisation of the trust as 'ideological.' However, rather than agreeing with Cotterrell that the trust disguises the true ownership of the beneficiary, it shows that the family trust subverts this idea of a one-sided ownership relation altogether by effecting a reversal in the hierarchical distinction between persons and things. Under the appearance of wealth, beneficial owners are serving the very things they own by ensuring their protection and continuous reproduction.

Electronic computers form an integral part of modern mathematical practice. Several high-profile results have been proven with techniques where computer calculations form an essential part of the proof. In the traditional philosophical literature, such proofs have been taken to constitute a posteriori knowledge. However, this traditional stance has recently been challenged by Mark McEvoy, who claims that computer calculations can constitute a priori mathematical proofs, even in cases where the calculations made by the computer are too numerous to be surveyed (...) by human agents. In this article we point out the deficits of the traditional literature that has called for McEvoy’s correction. We also explain why McEvoy’s defence of mathematical apriorism fails and we discuss how the debate over the epistemological status of computer-assisted mathematics contains several unfortunate conceptual reductions.

This work investigates how ancient philosophers understood productive knowledge or technê and used it to explain ethics, rhetoric, politics and cosmology. In eleven chapters leading scholars set out the ancient debates about technê from the Presocratic and Hippocratic writers, through Plato and Aristotle and the Hellenistic age, ending in the Neoplatonism of Plotinus and Proclus. Amongst the many themes that come into focus are: the model status of ancient medicine in defining the political art, the similarities between the Platonic and (...) Aristotelian conceptions of technê, the use of technê as a paradigm for virtue and practical rationality, technê´s determining role in Platonic conceptions of cosmology, technê´s relationship to experience and theoretical knowledge, virtue as an 'art of living', the adaptability of the criteria of technê to suit different skills, including philosophy itself, the use in productive knowledge of models, deliberation, conjecture and imagination.

This thesis promotes a therapeutic revision of fundamental assumptions in contemporary ontological thought. I show that none of the extant standard theories of objects provides a viable account of the numerical, qualitative, and trans-temporal identity of objects, and that this is due to certain substance-ontological premises. I argue that in order to state the identity conditions of objects we must abandon these premises, together with the idea that objects enjoy ontological primacy. ;I follow a methodological program of formally criticizing an (...) ontological framework by demonstrating that each of the theories developed within this framework is incoherent, i.e., either inconsistent or subject to vicious regress. I proceed in three steps. First, I show that the substance-ontological paradigm cannot be characterized in terms of its basic entities, since there is no extensional, intensional, or functional definition of the notion of substance common to all extant substance ontologies; consequently, I propose to describe the substance-ontological paradigm in terms of its basic assumptions. ;Second, I analyze the contemporary discussion of the problem of individuality, the problem of universals, and the problem of persistence, and uncover 22 characteristic implicit assumptions of substance ontology. I show on the basis of representative examples that, due to their commitment to substance-ontological presuppositions, all extant types of solutions to the three mentioned problems are incoherent. In particular, I take issue with the bare particular view, the qualified particular view, and the bundle view of individuality; different varieties of platonist and nominalist theories of universals and of relational and functional theories of predication; and the endurance and perdurance approaches to persistence. ;Third, while historical process-ontological schemes have dropped some of the revealed substance-ontological presuppositions, I finally explore the result of rejecting all of them and sketch a scheme based on dynamic masses which promises to yield coherent explanations of the ontological features of those complex processes which we commonly consider to be objects.

The robotics industry is growing rapidly, and to a large extent the development of this market sector is due to the area of social robotics – the production of robots that are designed to enter the space of human social interaction, both physically and semantically. Since social robots present a new type of social agent, they have been aptly classified as a disruptive technology, i.e. the sort of technology which affects the core of our current social practices and might lead (...) to profound cultural and social change. -/- Due to its disruptive and innovative potential, social robotics raises not only questions about utility, ethics, and legal aspects, but calls for “robo-philosophy” – the comprehensive philosophical reflection from the perspectives of all philosophical disciplines. This book presents the proceedings of the first conference in this new area, “Robo-Philosophy 2014 – Sociable Robots and the Future of Social Relations", held in Aarhus, Denmark, in August 2014. The short papers and abstracts collected here address questions of social robotics from the perspectives of philosophy of mind, social ontology, ethics, meta-ethics, political philosophy, aesthetics, intercultural philosophy, and metaphilosophy. -/- Social robotics is still in its early stages, but it is precisely now that we need to reflect its possible cultural repercussions. This book is accessible to a wide readership and will be of interest to everyone involved in the development and use of social robotics applications, from social roboticists to policy makers.

The jurists of classical Islamic Law defined the interior forum as a limit to the religious validity of the sentences of Muslim judges , because these have neither access to God's knowledge nor to the individual believer’s conscience and motivations. They can base their decisions solely on exterior appearances and can, therefore, neither be sure that their judgments correspond to the facts nor to the intentions and memories of the individuals concerned. This holds especially true for questions of belief and (...) unbelief. From the eighth to the nineteenth century, the norms of Islamic law were the result of learned debates among independent jurists and their schools of law. In the nineteenth and twentieth centuries, it was integrated into the codes enacted by the competent institutions of the national states and lost its normative authority in most spheres of the modern state law. It remained dominant only in personal statute law, i.e. the rules concerning marriage and divorce, family and succession. From the early seventies of the twentieth century, opposition against the neglect of religious norms in modern state law was centered on the demand for the “codification of Islamic law” . Its leaders were jurists trained in modern law faculties, who wanted to insert the norms of classical Islamic Law into the codes of the national state with which they are familiar. The ethical debates of classical Islamic law, obviously, did not lend themselves easily to such an approach.The jurists movement for the codification of Islamic law gained in momentum during the eighties when, in a number of states, it succeeded in assuring for the classical apostasy rules a place in the modern criminal codes. In other states, such as Egypt, the highest courts opened the way for apostasy trials. The analysis of one apostasy judgment of the highest Egyptian court shows that the court understands belief and apostasy as objective facts that can be separated from the person who professes or denies them. It is on this question that my lecture focuses. The court effectively claims the role of the highest instance in questions of belief and unbelief. Belief and apostasy thus become depersonalized objective facts without any relation to the intentions of the individuals concerned. The court’s sentence does not refer to the believer’s own interior forum : the concept seems to be irrelevant to the judges. Their definition of apostasy serves to control the ideas that can legitimately be discussed in the public sphere. It denies bold reinterpretations of Islam, but also a number of political persuasions and theories, the right of access to the public space and assigns them the private sphere as their legitimate abode. A new concept of private and public is thus developed in the detailed reasoning by which the court justifies its judgment.There is, to my understanding, nothing in the religion of Islam that renders such a stance necessary. Other courts, in Egypt, develop other ideas of the principles of Islamic normativity and in other Arab states go so far as to develop a concept of privacy that would forbid the debates discussed in this lecture. It seems important to underline that the use of classical elements in the court’s judgment does not conceal the fact that the ethical criteria of classical Muslim law find little place in this jurisdiction that represents a special version of modern legal positivism.

Processes constitute the world of human experience - from nature to cognition to social reality. Yet our philosophical and scientific theories of nature and experience have traditionally prioritized concepts for static objects and structures. The essays collected here call for a review of the role of dynamic categories in the language of theories. They present old and new descriptive tools for the modelling of dynamic domains, and argue for the merits of process-based explanations in ontology, cognitive science, semiotics, linguistics, philosophy (...) of mind, robotics, theoretical biology, music theory, and philosophy of chemistry and physics. The collection is of interest to professional researchers in any of these fields; it establishes - for the very first time - crossdisciplinary contact among recent process-based research movements and might witness a conceptual paradigm shift in the making.

In Risk and Rationality, Lara Buchak advertised REU theory as able to recover the modal preferences in the Allais paradox. But we pointed out that REU theory only applies in the “grand world” setting, where it actually struggles with the modal Allais preferences. Buchak offers two replies. Here we enumerate technical and philosophical problems they face.

Causation is extrinsic. What an event causes depends not just on its own nature and the laws, but on the environment in which it occurs. Had an event occurred under different conditions, it may have had different effects. Yet we often want to say that causation, in at least some respect, is not extrinsic. Events exert an influence on the world themselves, independently of what other events do or do not occur in their surroundings. This paper develops an account of (...) such influence and argues that it provides a solution to the causal exclusion problem. By locating that solution largely within the metaphysics of causation, we can solve the exclusion problem without taking on a commitment to a theory of mind. (shrink)

Ontic structural realists hold that structure is all there is, or at least all there is fundamentally. This thesis has proved to be puzzling: What exactly does it say about the relationship between objects and structures? In this article, I look at different ways of articulating ontic structural realism in terms of the relation between structures and objects. I show that objects cannot be reduced to structure, and argue that ontological dependence cannot be used to establish strong forms of structural (...) realism. At the end, I show how a weaker, but controversial, form of structural realism can be articulated on the basis of ontological dependence. (shrink)

The view that the soul can exist separately from the body is commonly associated with dualism. Since Plato’s Phaedo (Phd.) argues that the soul is immortal and survives the death of the body, there seems to be reason to call Plato, in that dialogue at least, a ‘dualist’. Yet, as we know, there are many kinds of dualism, so we have thereby not said very much. Let me therefore start with some distinctions. First of all, we can distinguish between two (...) kinds of dualism which say that the soul is a different kind of substance from the body. On one version, call it ‘strong’ substance dualism, no properties of mind can also be properties of body. Mind is defined as a kind of thing that uniquely has a certain property or set of properties, say consciousness, just as body is defined by its unique properties, say spatial extension. This would seem to be Descartes’ view. On another version, call it ‘weak’ substance dualism, no essential or defining properties of mind are also properties of body. This leaves it open whether the mind and body may share some accidental or non-defining properties. Finally, there is an even weaker kind of dualism which we may call property dualism. According to this view, there are mental properties which are distinct from and irreducible to bodily properties.4 However, these mental properties may or not be properties of an underlying substance that also has bodily properties. In other words, the same thing may have both mental and bodily properties, so having mental properties is not enough to make something a different kind of substance. (shrink)
