: This paper addresses the need to examine teaching practices from the observation that they are beyond what they should be. This task devolved to scientists of education is to learn about teaching practices in their relationship to student learning in order to build the database useful to teacher educators and reflexivity necessary for any teacher about their own practice. The concepts of competence, pattern and are useful instrument in this endeavor of explanation and understanding of the practices. The proposed (...) theoretical framework is illustrated by a perspective of teaching practices of teachers in schools and colleges. These differ in many aspects and this requires the testing of new hypotheses to explain -/- La présente contribution traite de la nécessité d’étudier les pratiques d’enseignement à partir du constat de ce qu’elles sont au delà de ce qu’elles devraient être. Cette tâche dévolue aux chercheurs en sciences de l’éducation vise à mieux connaître les pratiques d’enseignement dans leurs relations aux apprentissages des élèves afin de constituer la base de données utiles aux formateurs d’enseignants et nécessaire à toute réflexivité des enseignants à propos de leur propre pratique. Les notions de compétence, de schème et d’instrument sont utiles à cette entreprise d’explication et de compréhension des pratiques. La proposition de cadrage théorique est illustrée par une mise en perspective des pratiques d’enseignement de professeurs des écoles et de collèges. Celles-ci se distinguent sur bien des aspects ce qui réclame la mise à l’épreuve de nouvelles hypothèses explicatives. (shrink)

Grief is, and has always been, technologically supported. From memorials and shrines to photos and saved voicemail messages, we engage with the dead through the technologies available to us. As our technologies evolve, so does how we grieve. In this paper, we consider the role chatbots might play in our grieving practices. Influenced by recent phenomenological work, we begin by thinking about the character of grief. Next, we consider work on developing “continuing bonds” with the dead. We argue that for (...) some, chatbots may play an important role in establishing these continuing bonds by helping us develop what we term “habits of intimacy”. We then turn to the “ick factor” some may feel about this prospect, focusing especially on ethical concerns raised by Patrick Stokes and Adam Buben about the risk of replacing our dead with chatbots. We argue that replacement worries are not as pressing as Stokes and Buben suggest. We resist these replacement worries by appealing to the “thin reciprocity”, as we refer to it, that such bots offer, as well as the fictionalist stance that we think users of the bots adopt when engaging with them. We conclude by briefly raising some additional concerns and highlighting future research questions. (shrink)

Philosophical work exploring the relation between cognition and the Internet is now an active area of research. Some adopt an externalist framework, arguing that the Internet should be seen as environmental scaffolding that drives and shapes cognition. However, despite growing interest in this topic, little attention has been paid to how the Internet influences our affective life — our moods, emotions, and our ability to regulate these and other feeling states. We argue that the Internet scaffolds not only cognition but (...) also affect. Using various case studies, we consider some ways that we are increasingly dependent on our Internet-enabled “techno-social niches” to regulate the contours of our own affective life and participate in the affective lives of others. We argue further that, unlike many of the other environmental resources we use to regulate affect, the Internet has distinct properties that introduce new dimensions of complexity to these regulative processes. First, it is radically social in a way many of these other resources are not. Second, it is a radically distributed and decentralized resource; no one individual or agent is responsible for the Internet’s content or its affective impact on users. Accordingly, while the Internet can profoundly augment and enrich our affective life and deepen our connection with others, there is also a distinctive kind of affective precarity built into our online endeavors as well.

A family of recent externalist approaches in philosophy of mind argues that our psychological capacities are synchronically and diachronically “scaffolded” by external resources. I consider how these “scaffolded” approaches might inform debates in phenomenological psychopathology. I first introduce the idea of “affective scaffolding” and make some taxonomic distinctions. Next, I use schizophrenia as a case study to argue—along with others in phenomenological psychopathology—that schizophrenia is fundamentally a self-disturbance. However, I offer a subtle reconfiguration of these approaches. I argue that schizophrenia (...) is not simply a disruption of ipseity or minimal self-consciousness but rather a disruption of the scaffolded self, established and regulated via its ongoing engagement with the world and others. I conclude by considering how this scaffolded framework indicates the need to consider new forms of intervention and treatment. (shrink)

I consider applications of “AI extenders” (Vold & Hernández-Orallo 2021) to dementia care. AI extenders are AI-powered technologies that extend minds in ways interestingly different from old-school tech like notebooks, sketch pads, models, and microscopes. I focus on AI extenders as ambiance: so thoroughly embedded into things and spaces that they fade from view and become part of a subject’s taken-for-granted background. Using dementia care as a case study, I argue that ambient AI extenders are promising because they afford richer (...) and more durable forms of multidimensional integration than do old-school extenders like Otto’s notebook. They can be tailored, in fine-grained ways along multiple timescales, to a user’s particular needs, values, and preferences — and crucially, they can do much of this self-optimizing on their own. I discuss why this is so, why it matters, and its potential impact on affect and agency. I conclude with some worries in need of further discussion. (shrink)

There is growing philosophical interest in “affective injustice”: injustice faced by individuals specifically in their capacity as affective beings. Current debates tend to focus on affective injustice at the psychological level. In this paper, I argue that the built environment can be a vehicle for affective injustice — specifically, what Wildman et al. (2022) term “affective powerlessness”. I use resources from ecological psychology to develop this claim. I consider two cases where certain kinds of bodies are, either intentionally or unintentionally, (...) deprived of access to goods affording the development and maintenance of their subjective well-being: hostile architecture and masking practices in autism. This deprivation, I argue further, leads to a significant weakening and diminishment of their spatial agency, hinders their well-being, and in so doing gives rise to a pervasive experience of affective powerlessness. By drawing attention to these themes, I show that an ecological approach helpfully supplements existing approaches. It highlights how affective injustice can emerge via the way bodies are positioned in space, and the central role that built environments play in determining this positioning. (shrink)

This book is concerned with the role of intuitions in the justification of philosophical theory. The author begins by demonstrating how contemporary philosophers, whether engaged in case-driven analysis or seeking reflective equilibrium, rely on intuitions as evidence for their theories. The author then provides an account of the nature of philosophical intuitions and distinguishes them from other psychological states. Finally, the author defends the use of intuitions as evidence by demonstrating that arguments for skepticism about their evidential value are either (...) self-defeating or guilty of arbitrary and unjustified partiality towards non-intuitive modes of knowledge.

The problem of other minds has a distinguished philosophical history stretching back more than two hundred years. Taken at face value, it is an epistemological question: it concerns how we can have knowledge of, or at least justified belief in, the existence of minds other than our own. In recent decades, philosophers, psychologists, neuroscientists, anthropologists and primatologists have debated a related question: how we actually go about attributing mental states to others (regardless of whether we ever achieve knowledge or rational (...) justification in this domain). Until the mid-nineties, the latter debate – which sometimes goes under the name of the “mindreading” debate – was characterized by a fairly clear-cut opposition between two theoretical outlooks: “theory-theory” (TT) and “simulation theory” (ST). Theory-theorists typically argued that we attribute mental states to others on the basis of a “theory of mind” that is either constructed in early infancy and subsequently revised and modified (Gopnik 1996), or else is the result of maturation of innate mindreading “modules” (Baron-Cohen 1995).

In “The Child’s Relations with Others,” Merleau-Ponty argues that certain early experiences are jointly owned in that they are numerically single experiences that are nevertheless given to more than one subject (e.g., the infant and caregiver). Call this the “joint ownership thesis” (JT). Drawing upon both Merleau-Ponty’s phenomenological analysis, as well as studies of exogenous attention and mutual affect regulation in developmental psychology, I motivate the plausibility of JT. I argue that the phenomenological structure of some early infant–caregiver dyadic exchanges (...) is best described as involving joint subjects. From birth, some experiences are constitutively social in that certain phenomenal states, such as the positive emotions that arise within these early exchanges, are jointly owned. Along the way, I consider a possible objection. I conclude by considering the explanatory significance of adopting JT. (shrink)

I present a perceptual account of other minds that combines a Husserlian insight about perceptual experience with a functionalist account of mental properties.

We provide self-contained proof of a theorem relating probabilistic coherence of forecasts to their non-domination by rival forecasts with respect to any proper scoring rule. The theorem recapitulates insights achieved by other investigators, and clarifi es the connection of coherence and proper scoring rules to Bregman divergence.

This paper is an exploration of how we do things with music—that is, the way that we use music as an esthetic technology to enact micro-practices of emotion regulation, communicative expression, identity construction, and interpersonal coordination that drive core aspects of our emotional and social existence. The main thesis is: from birth, music is directly perceived as an affordance-laden structure. Music, I argue, affords a sonic world, an exploratory space or nested acoustic environment that further affords possibilities for, among other (...) things, (1) emotion regulation and (2) social coordination. When we do things with music, we are engaged in the work of creating and cultivating the self, as well as creating and cultivating a shared world that we inhabit with others. I develop this thesis by first introducing the notion of a musical affordance . Next, I look at how emotional affordances in music are exploited to construct and regulate emotions. I summon empirical research on neonate music therapy to argue that this is something we emerge from the womb knowing how to do. I then look at social affordances in music, arguing that joint attention to social affordances in music alters how music is both perceived and appropriated by joint attenders within social listening contexts. In support, I describe the experience of listening to and engaging with music in a live concert setting. Thinking of music as an affordance-laden structure thus reaffirms the crucial role that music plays in constructing and regulating emotional and social experiences in everyday life. (shrink)

Politicians, preachers, and ordinary people speak often of character; psychologists study `personality', used as a term of art with meanings close to `character'. Most ethical philosophers in the last two hundred years, on the other hand, have not had much to say about character. This book attempts to understand character and to refocus ethical philosophy so that character is central.

Isaac explores how influential thinkers in the mid-twentieth century understood the relations among science, knowledge, and the empirical study of human affairs. He places special emphasis on the practical, local manifestations of their complex theoretical ideas, particularly the institutional milieu of Harvard University.

I respond to the commentaries on 'Grace de Laguna's Analytic and Speculative Philosophy' offered by Peter Olen [2023], Trevor Pearce, Anthony Fisher, Marguerite La Caze and Frederique Janssen-Lauret. In doing so, I bring out some of the value of de Laguna’s perspectivism and of her treatment of modality. I also further clarify how she departs from pragmatism and from analytic philosophy, and how she relates to continental philosophy.

Though most of analytic philosophy is based upon intuitions, some philosophers are beginning to question whether intuitions are an appropriate basis for philosophical theory. This paper responds to the arguments of some contemporary philosophers who hold that intuitions should not be treated as evidence for anything other than our contingent psychological constitution. It begins with a demonstration that skeptical arguments by Gilbert Harman and Alvin Goldman are variations on an argument with the potential to undermine the use of intuitions in (...) much philosophical inquiry. After a demonstration that Nicholas Sturgeon’s response to Harman’s argument is inadequate, it argues that all of the instances of the skeptical argument are unsuccessful because they are epistemically self-defeating.

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to provide (...) a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

The aim of this essay is to situate the thought of Tetsurō Watsuji within contemporary approaches to social cognition. I argue for Watsuji’s current relevance, suggesting that his analysis of embodiment and social space puts him in step with some of the concerns driving ongoing treatments of social cognition in philosophy of mind and cognitive science. Yet, as I will show, Watsuji can potentially offer a fruitful contribution to this discussion by lending a phenomenologically informed critical perspective. This is because (...) Watsuji challenges the internalist and cognitivist presuppositions informing the currently dominant “Theory of Mind” paradigm that is driving much social cognition research. Additionally, I show that Watsuji’s alternative model is not merely confined to the realm of phenomenological description but that it also receives robust empirical support from a number of different sources. I thus hope to open up aspects of Watsuji’s thinking that have yet to be fully appreciated. (shrink)

Disability has been a topic in multiple areas of philosophical scholarship for decades. However, it is only in the last ten to fifteen years that philosophy of disability has increasingly become recognized as a distinct field. Engaging a range of canonical texts across the Western intellectual tradition, I argue that the foundational question of continental philosophy of disability is the question of the meaning of ability. I then explore three pathways toward this question: the verdict of bodies, the bind of (...) bodies and worth, and the dogma of individual ability. I contend that unlike the question of the meaning of being, the question of the meaning of ability is not simply a problem of forgetting but instead primarily a problem of dehumanization. (shrink)

When firm misconduct comes to light, CEOs are often faced with difficult decisions regarding whether and how to respond to stakeholder demands as they attempt to restore their firms’ legitimacy. Prior research largely assumes that such decisions are motivated by CEOs’ calculated attempts to manage stakeholder impressions. Yet, there are likely other motives, particularly those of a morally-relevant nature, that might also be influencing CEOs’ decisions. To address this limitation, we advance moral cleansing as an alternative explanation for how and (...) why CEOs lead their firms to respond to stakeholder demands following the firm’s misconduct and, in turn, whether they can successfully restore their firm’s legitimacy. In the context of firm misconduct, moral cleansing motives reflect CEOs’ desire to restore their threatened moral self-image resulting from the misconduct. We theorize that a CEO’s moral cleansing motives increase the likelihood that their firm will engage in a series of reparative responses that can restore the firm’s legitimacy (i.e., discovery, explanation, penance, and rehabilitation). In addition, we explicate the unique implications of CEOs’ moral cleansing in a post-misconduct context by theorizing how such motives may simultaneously improve one form of their firms’ legitimacy while hindering another. Specifically, we theorize that CEOs’ moral cleansing motives increase (decreases) the authenticity (strategic cognition) of their firm responses, which strengthens (weakens) the effectiveness of those responses on the firms’ ability to restore its moral (pragmatic) legitimacy with stakeholders. We conclude with a discussion of the implications of this work. (shrink)

Should society intervene to prevent the risky behavior of precocious teenagers even if it would be impermissible to intervene with adults who engage in the same risky behavior? The problem is well illustrated by the legal case of the 13-year-old Dutch girl Laura Dekker, who set out in 2009 to become the youngest person ever to sail around the world alone, succeeding in January 2012. In this paper we use her case as a point of entry for discussing the fundamental (...) question of how to demarcate childhood from adulthood. After summarizing the case, we identify a ‘demarcation dilemma’ that frames much of the public and expert debate. On the one hand, it seems morally imperative ‘to treat like alike’, which means that both children and adults should be allowed to undertake all actions for which they have the relevant competences. On the other hand, requiring proportional treatment of children and adults seems to neglect the special nature of childhood as a distinct stage in life that ends at a specific age. We introduce the notion of a ‘regime of childhood’ to deal with this problem. This regime includes several dimensions, including the limited liability for children, the supervisory responsibilities of parents, the role of age-based thresholds, and the overarching purpose of childhood as a context for developing autonomy. We argue that, all things considered, there are good reasons not to shift to a regime that offers individual children the option of qualifying for adulthood on the basis of age-neutral criteria.

This chapter offers the beginning of an enactive account of auditory experience—particularly the experience of listening sensitively to music. It investigates how sensorimotor regularities grant perceptual access to music qua music. Two specific claims are defended: (1) music manifests experientially as having complex spatial content; (2) sensorimotor regularities constrain this content. Musical content is thus brought to phenomenal presence by bodily exploring structural features of music. We enact musical content.

Moderate rationalists maintain that our rational intuitions provide us with prima facie justification for believing various necessary propositions. Such a claim is often criticized on the grounds that our having reliable rational intuitions about domains in which the truths are necessary is inexplicable in some epistemically objectionable sense. In this paper, I defend moderate rationalism against such criticism. I argue that if the reliability of our rational intuitions is taken to be contingent, then there is no reason to think that (...) our reliability is inexplicable. I also suggest that our reliability is, in fact, necessary, and that such necessary reliability neither admits of, nor requires, any explanation of the envisaged sort. (shrink)

In this article, we describe a hitherto undocumented fallacy-in the sense of a mistake in reasoning-constituted by a negativity bias in the way that people attribute motives to others. We call this the "worst-motive fallacy," and we conducted two experiments to investigate it. In Experiment 1, participants expected protagonists in a variety of fictional vignettes to pursue courses of action that satisfy the protagonists' worst motive, and furthermore, participants significantly expected the protagonist to pursue a worse course of action than (...) they would prefer themselves. Experiment 2 was a preregistered attempted replication of Experiment 1, including a bigger range of vignettes; the first effect was not replicated for the new vignettes tested but was for the original set. Also, we once again found that participants expected protagonists to be more likely than they were themselves to pursue courses of action that they considered morally bad. We discuss the worst-motive fallacy's relation to other well-known biases as well as its possible evolutionary origins and its ethical consequences. (shrink)

Phenomenology is the general study of the structure of experience, from thought and perception, to self-consciousness, bodily-awareness, and emotion. It is both a fundamental area of philosophy and a major methodological approach within the human sciences. Experiencing Phenomenology is an outstanding introduction to phenomenology. Approaching fundamental phenomenological questions from a critical, systematic perspective whilst paying careful attention to classic phenomenological texts, the book possesses a clarity and breadth that will be welcomed by students coming to the subject for the first (...) time. Accessibly written, each chapter relates classic phenomenological discussions to contemporary issues and debates in philosophy. The following key topics are introduced and explained: the methodological foundations of phenomenology intentionality as the ‘mark of the mental’ and the problem of non-existent objects perceptual experience, including our awareness of things, properties, and events the experience of body, self, and others imaginative and emotional experience detailed discussions of classical phenomenological texts, including: Brentano's _Psychology from an Empirical Standpoint _ Husserl's _Logical Investigations_, _Cartesian Meditations, _and On_ the Phenomenology of the Consciousness of Internal Time _ Heidegger’s _History of The Concept of Time,_ and _Being and Time _ Stein's _On the Problem of Empathy _ Sartre's _Transcendence of the Ego_, _Sketch for a Theory of the Emotions,_ and _The Imaginary _ Merleau-Ponty's Phenomenology of Perception. Also included is a glossary of key terms and suggestions for further reading, making this book an ideal starting point for anyone new to the study of phenomenology, not only in Philosophy but related disciplines such as Psychology and Sociology.

This paper pursues two main aims. First, it distinguishes two kinds of improvisation: expert and inexpert. Expert improvisation is a (usually artistic) practice that the agent consciously sets as their goal and is evaluated according to (usually artistic) standards of improvisation. Inexpert improvisation, by contrast, supports and structures the agent’s action as it moves them towards their (usually everyday life) goals and is evaluated on its success leading the agent to the achievement of those goals. The second aim is to (...) describe inexpert improvisation as a robustly distributed affair, one that involves the ongoing integration of embodied practices with social and material resources within our surrounding environments. On the wide approach to improvisation fostered in this paper, inexpert improvisation is claimed to be our default way of inhabiting our world. (shrink)

Does natural selection explain why individual organisms have the traits that they do? According to "the Negative View," natural selection does not explain why any individual organism has the traits that it does. According to "the Positive View," natural selection at least sometimes does explain why an individual organism has the traits that it does. In this paper, I argue that recent arguments for the Positive View fail in virtue of running afoul of the doctrine of origin essentialism and I (...) demonstrate that other recent defenses of the Negative View depend upon my own for their plausibility.

In this paper, we take moral agency to be that context in which a particular agent can, appropriately, be held responsible for her actions and their consequences. In order to understand moral agency, we will discuss what it would take for an artifact to be a moral agent. For reasons that will become clear over the course of the paper, we take the artifactual question to be a useful way into discussion but ultimately misleading. We set out a number of (...) conceptual pre-conditions for being a moral agent and then outline how one should — and should not — go about attributing moral agency. In place of a litmus test for such an agency — such as Allen et al.'s Moral Turing Test — we suggest some tools from the conceptual spaces theory and the unified conceptual space theory for mapping out the nature and extent of that agency.

One argument for the thirder position on the Sleeping Beauty problem rests on direct inference from objective probabilities. In this paper, I consider a particularly clear version of this argument by John Pollock and his colleagues (The Oscar Seminar 2008). I argue that such a direct inference is defeated by the fact that Beauty has an equally good reason to conclude on the basis of direct inference that the probability of heads is 1/2. Hence, neither thirders nor halfers can find (...) direct support in an appeal to objective probabilities. (shrink)

Virtue ethicists argue that modern ethical theories aim to give direct guidance about particular situations at the cost of offering artificial or narrow accounts of ethics. In contrast, virtue ethical theories guide action indirectly by helping one understand the virtues—but the theory will not provide answers as to what to do in particular instances. Recently, this had led many to think that virtue ethical theories are self-effacing the way some claim consequentialist and deontological theories are. In this paper I defend (...) virtue ethics against the charge of self-effacement. I distinguish between modestly self-effacing theories, immodestly self-effacing theories and theories that recommend indirect guidance. Though all self-effacing theories are indirect, not all indirect theories are self-effacing. I argue that virtue ethics is not self-effacing, but rather indirectly action-guiding. The response I articulate draws on the distinctive virtue ethical mode of action-guidance: namely, that thinking hard about virtue and what kind of person one aims to be offers the kind of guidance we want (or should want) as we face practical moral problems.

We present several generalizations of the well-known Kunen inconsistency that there is no nontrivial elementary embedding from the set-theoretic universe V to itself. For example, there is no elementary embedding from the universe V to a set-forcing extension V[G], or conversely from V[G] to V, or more generally from one set-forcing ground model of the universe to another, or between any two models that are eventually stationary correct, or from V to HOD, or conversely from HOD to V, or indeed (...) from any definable class to V, among many other possibilities we consider, including generic embeddings, definable embeddings and results not requiring the axiom of choice. We have aimed in this article for a unified presentation that weaves together some previously known unpublished or folklore results, several due to Woodin and others, along with our new contributions.

Biologists and philosophers have long recognized the importance of species, yet species concepts serve two masters, evolutionary theory on the one hand and taxonomy on the other. Much of present-day evolutionary and systematic biology has confounded these two roles primarily through use of the biological species concept. Theories require entities that are real, discrete, irreducible, and comparable. Within the neo-Darwinian synthesis, however, biological species have been treated as real or subjectively delimited entities, discrete or nondiscrete, and they are often capable (...) of being decomposed into other, smaller units. Because of this, biological species are generally not comparable across different groups of organisms, which implies that the ontological structure of evolutionary theory requires modification. Some biologists, including proponents of the biological species concept, have argued that no species concept is universally applicable across all organisms. Such a view means, however, that the history of life cannot be embraced by a common theory of ancestry and descent if that theory uses species as its entities.These ontological and biological difficulties can be alleviated if species are defined in terms of evolutionary units. The latter are irreducible clusters of reproductively cohesive organisms that are diagnosably distinct from other such clusters. Unlike biological species, which can include two or more evolutionary units, these phylogenetic species are discrete entities in space and time and capable of being compared from one group to the next.

The idea that there are ‘laws of nature’ is a widespread scientific opinion. On the one hand, I argue that this idea has the crucial function to explain the obvious similarities of physical processes. On the other hand, I show that this idea can be replaced by the hypothesis supporting that a minimal consciousness immanent to matter governs its processes. This latter hypothesis may seem surprising, but compared to that of laws, it is more empirical in the sense that it (...) is inspired by our conscious experience, in particular our experience of automatic actions. And it is deflationist, because it allows us to reject the existence of laws, which must be considered as Platonistic forms. This hypothesis has been supported by Peirce and Bergson. In this paper, I try to clarify and complete their views, and to draw the consequences for the study of consciousness. (shrink)

A major reason that Confucius should matter to Western ethical philosophers is that some of his concerns are markedly different from those most common in the West. A Western emphasis has been on major choices that are treated in a decontextualized way. Confucius’ emphasis is on paths of life, so that context matters. Further, the nuances of personal relations get more attention than is common (with the exception of feminist ethics) in Western philosophy. What Confucius provides is a valuable aid (...) in arriving at a more balanced sense of what ethics is concerned with. It also allows us to realize the importance of sensitivity to particulars. Finally, it highlights the importance of style (as well as the content of what is chosen) in behavior, and the ways in which relations with family and friends can connect with choices in a wider “public” sphere.

The thesis that numbers are ratios of quantities has recently been advanced by a number of philosophers. While adequate as a definition of the natural numbers, it is not clear that this view suffices for our understanding of the reals. These require continuous quantity and relative to any such quantity an infinite number of additive relations exist. Hence, for any two magnitudes of a continuous quantity there exists no unique ratio. This problem is overcome by defining ratios, and hence real (...) numbers, as binary relations between infinite standard sequences. This definition leads smoothly into a new definition of measurement consonant with the traditional view of measurement as the discovery or estimation of numerical relations. The traditional view is further strengthened by allowing that the additive relations internal to a quantity are distinct from relations observed in the behaviour of objects manifesting quantities. In this way the traditional theory can accommodate the theory of conjoint measurement. This is worth doing because the traditional theory has one great strength lacked by its rivals: measurement statements and quantitative laws are able to be understood literally. 1 This paper was completed in 1990-1. while the author was a visiting scholar at the Irvine Research Unit in Mathematical Behavioral Sciences.
