Barbey & Sloman (B&S) advocate a dual-process (two-system) approach by comparing it with an alternative perspective (ecological rationality), claiming that the latter is unwarranted. Rejecting this alternative approach cannot serve as sufficient evidence for the viability of the former.

Setting the two hypotheses of complete neglect and full use of base rates against each other is inappropriate. The proper question concerns the degree to which base rates are used (or neglected), and under what conditions. We outline alternative approaches and recommend regression analysis. Koehler's conclusion that we have been oversold on the base rate fallacy seems to be premature.

This study explored attention and interpretation biases in processing facial expressions as correlates of theoretically distinct self-reported anger experience, expression, and control. Non-selected undergraduate students completed cognitive tasks measuring attention bias, interpretation bias, and Spielberger’s State-Trait Anger Expression Inventory. Attention bias toward angry faces was associated with higher trait anger and anger expression and with lower anger control-in and anger control-out. The propensity to quickly interpret ambiguous faces as angry was associated with greater anger expression and its subcomponent of anger (...) expression-out and with lower anger control-out. Interactions between attention and interpretation biases did not contribute to the prediction of any anger component suggesting that attention and interpretation biases may function as distinct mechanisms. Theoretical and possible clinical implications are discussed. (shrink)

Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” illusion) (...) led to a greatly diminished illusory effect. Although these differences may arise from the different processes underlying these illusions (size contrast vs. size constancy), the dynamic variants we tested in our previous work also differed in the nature of the dynamic elements; specifically, whereas the Dynamic Ebbinghaus included a moving target and inducers that changed size and position, the Dynamic Corridor only included a moving target on a static background. Here, we explore further dynamic versions of the Ebbinghaus illusion and the Corridor and Ponzo illusions by separately manipulating three types of dynamic elements: target motion, context translation, and dynamic changes in context. Across five experiments examining 21 dynamic illusory configurations, adding target motion or a dynamically changing context separately resulted in little-to-no illusory effect. In contrast, the combination of target motion and a dynamically changing context led to a robust size illusion, consistent with an interactive effect. However, illusory effects that exceeded the matched classic, static illusory configuration were only observed for the dynamic versions of the Ebbinghaus illusion and the Revealed Ponzo illusions, in which the contextual elements changed size. We conclude that the combination of target motion and a dynamically changing context are necessary to produce dynamic size illusions, but that enhancement above and beyond static illusions may be largely specific to size contrast effects. Our results have important implications for the integration of motion signals, a ubiquitous environmental stimulus, in the perception of object size. (shrink)

Region R Question: How many objects — entities, things — are contained in R? Ignore the empty space. Our question might better be put, 'How many material objects does R contain?' Let's stipulate that A, B and C are metaphysical atoms: absolutely simple entities with no parts whatsoever besides themselves. So you don't have to worry about counting a particle's top half and bottom half as different objects. Perhaps they are 'point-particles', with no length, width or breadth. Perhaps they are (...) extended in space without possessing spatial parts (if that is possible). Never mind. We stipulate that A, B and C are perfectly simple. We also stipulate that they are connected as follows. A and B are stuck together in such a way that when a force is applied to one of them, they move together 'as a unit'. Moreover, the two of them together exhibit behavior that neither would exhibit on its own — Perhaps they emit a certain sound, or glow in the dark — whereas C is.. (shrink)

Traditionally, definitions of art have been concerned with the characteristics of the art object, the process of its creation or the reactions to it. in this paper i suggest to concentrate on the circumstances of the object's existence and the process by which it comes to exist. these circumstances, which differ in different periods and in different societies, are: (a) it's being declared, either by the artist, or by an exhibition catalogue, or by a collector, or by an art expert, (...) that x is art; (b) it's being understood that the said object in a museum, gallery, concert-hall, living room, is located or arranged or hung in such a way as to indicate that it is being exhibited as a work of art; (c) the said object's resembling objects previously recognized as being works of art; (d) the said declaration, referred to in (a), being made in the proper media--those recognized as having authority in the realm of art.

We present a rigorous way to evaluate the visual perception of correlation in scatterplots, based on classical psychophysical methods originally developed for simple properties such as brightness. Although scatterplots are graphically complex, the quantity they convey is relatively simple. As such, it may be possible to assess the perception of correlation in a similar way. Scatterplots were each of 5.0 extent, containing 100 points with a bivariate normal distribution. Means were 0.5 of the range of the points, and standard deviations (...) 0.2 of this range. Precision was determined via an adaptive algorithm to find the just noticeable differences (jnds) in correlation, i.e., the difference between two side-by-side scatterplots that could be discriminated 75% of the time. Accuracy was measured by direct estimation, using reference scatterplots with fixed upper and lower values, with a test scatterplot adjusted so that its correlation appeared to be halfway between these. This process was recursively applied to yield several further estimates. Results of the discrimination tests show jnd(r) = k (1/b – r), where r is the Pearson correlation, and parameters 0 < k, b < 1. Integration yields a subjective estimate of correlation g(r) = ln(1 – br) / ln(1– b). The values of b found via discrimination closely match those found via direct estimation. As such, it appears that the perception of correlation in a scatterplot is completely described by two related performance curves, specified by two easily-measured parameters. (shrink)

The literature on thought experiments has been mainly concernedwith thought experiments that are directed at a theory, be it in aconstructive or a destructive manner. This has led somephilosophers to argue that all thought experiments can beformulated as arguments. The aim of this paper is to drawattention to a type of thought experiment that is not directed ata theory, but fulfills a specific function within a theory. Suchthought experiments are referred to as functional thoughtexperiments, and they are routinely used in (...) applied statistics. An example is given from frequentist statistics, where a thoughtexperiment is required to establish the probability space. It isconcluded that (a) not all thought experiments can be formulated asarguments, and (b) the role of thought experiments is more generaland more important to scientific reasoning than has previouslybeen recognized.

Reid maintained that the perceptions that we obtain from the senses of smell, taste, hearing, and touch are ‘suggested’ by corresponding sensations. However, he made an exception for the sense of vision. According to Reid, our perceptions of the real figure, position, and magnitude of bodies are suggested by their visible appearances, which are not sensations but objects of perception in their own right. These visible appearances have figure, position, and magnitude, as well as ‘colour,’ and the standard view among (...) Reid scholars has been that Reid maintained that our perceptions of visible figure, position, and magnitude are also not suggested by any sensation. They are instead suggested by the material impression on the retina. Gideon Yaffe challenges the standard interpretation. According to Yaffe, Reid believed that our perceptions of visible figure are suggested by corresponding sensations, by sensations of colour. We defend the standard interpretation of Reid. According to Reid, there is no “local sign” in our sensations of colour. The same colour sensation can be associated with different positions on the visual field, and different colour sensations can be associated to the same position on the visual field. According to Reid, we only have evidence for a correlation between the image on the retina and the perception of visible figure. (shrink)

Manifest Activity presents and critically examines the model of human power, the will, our capacities for purposeful conduct, and the place of our agency in the natural world of one of the most important and traditionally under-appreciated philosophers of the 18th century: Thomas Reid. For Reid, contrary to the view of many of his predecessors, it is simply manifest that we are active with respect to our behaviours; it is manifest, he thinks, that our actions are not merely remote products (...) of forces that lie outside of our control. Reid holds, instead, that actions are all and only those events that spring from active power and he produces insightful and imaginative arguments for the claim that only a creature with a mind is capable of having active power. He believes that only human beings, and creatures 'above us', are capable of directing events towards ends, of endowing them with purpose or direction, the distinctive feature of action. However, he also holds that all events, and not merely human actions, are products of active power, power possessed either by human beings or by God. This collection of theses leads Reid to the view that human behaviour and the progress of nature are both essentially teleological. Patterns in nature are the products of laws of which God is the author; patterns in human conduct are the products of character and the laws that individuals set for themselves. Manifest Activity examines Reid's arguments for this view and the view's implications for the nature of character, motivation and the special kind of causation involved in the production of human behavior.

Our study considers the governance, ethics and operational challenges associated with the acquisition, manipulation and commodification of ‘big data’ in the financial services sector. To the best of our knowledge, there are no published studies describing empirical research undertaken within companies in this sector to understand how they are responding to such challenges: our field-based research is a significant initial contribution in this respect. We describe the results of a micro-ethnographic study undertaken in a small-to-medium-sized company developing disruptive, technology-related platforms (...) and services in the banking and retail sectors based on big data and associated analytics: these are used to derive commercially valuable insights from personal customer data in exchange for cash back and targeted rewards. The company was found to employ a multi-level innovation governance approach, underpinned by an ethical strategy based on a principle of mutual benefit. Opt-in and informed consent for using data for specific purposes was supported by principles of data minimisation and anonymisation, with unrestricted use of secondary, anonymised and aggregated data to develop insights. Governance, which included contextual data protection legislation, payment-card industry data usage standards and internal corporate controls, presented as bespoke organisational practices relating to data security and privacy. These in total set the governance and ethics frame for big data innovation at the company within which it has had to be both adaptive and responsive under conditions of normative and regulatory uncertainty.

Criminal defendants cannot be punished unless found guilty “beyond a reasonable doubt”. Under probabilistic accounts, this means that the probability of guilt given the evidence is above a certain numerical threshold, such as 0.9. Under psychological accounts, by contrast, what is essential is that a factfinder reaches a certain psychological attitude toward guilt, such as certainty or unwavering belief, when contemplating the evidence. An adequate account should provide a normative explanation for why guilt BARD warrants punishment. Psychological accounts are more (...) likely to meet this challenge than probabilistic, it is argued. The permissibility of punishment is likely to be relative to the cognitive attitudes of the punisher, but not to the conditional probability of guilt in light of the evidence. (shrink)

Transplantation programs commonly rely on clinicians’ judgments about patients’ social support (care from friends or family) when deciding whether to list them for organ transplantation. We examine whether using social support to make listing decisions for adults seeking transplantation is morally legitimate, drawing on recent data about the evidence-base, implementation, and potential impacts of the criterion on underserved and diverse populations. We demonstrate that the rationale for the social support criterion, based in the principle of utility, is undermined by its (...) reliance on tenuous evidence. Moreover, social support requirements may reinforce transplant inequities, interfere in patients’ personal relationships, and contribute to biased and inconsistent listing procedures. As such, accommodating the needs of patients with limited social support would better balance ethical commitments to equity, utility, and respect for persons in transplantation. We suggest steps for researchers, transplantation programs, and policymakers to improve fair use of social support in transplantation. (shrink)

Using anthropological theory, this paper examines human–android interactions (HAI) as an emerging aspect of android science. These interactions are described in terms of adaptive learning (which is largely subconscious). This article is based on the observations reported and supplementary data from two studies that took place in Japan with a teleoperated android robot called Telenoid in the socialization of school children and older adults. We argue that interacting with androids brings about a special context, an interval, and a space/time for (...) reflection and imagination that was not there before. During the interaction something happens. There is adaptive learning and as a result, both children and older adults accepted Telenoid, and the children and older adults accepted each other. Using frames of play and ritual, we make sense and ‘capture’ moments of adaptive learning, and the feedback that elicits a social response from all study participants that results in self-efficacy and socialization. While “ritual” refers to the application of what has been learned and “play” means that there are no obvious consequences of what has been learned. This analysis illuminates new understanding about the uncanny valley, cultural robotics and the therapeutic potential of HAI. This has implications for the acceptance of androids in ‘socialized roles’ and gives us insight into the subconscious adaptive learning processes that must take place within humans to accept androids into our society. This approach aims to provides a clearer conceptual basis and vocabulary for further research of android and humanoid development. (shrink)

BackgroundNational guidelines require programmes use subjective assessments of social support when determining transplant suitability, despite limited evidence linking it to outcomes. We examined how transplant providers weigh the importance of social support for kidney transplantation compared with other factors, and variation by clinical role and personal beliefs.MethodsThe National survey of the American Society of Transplant Surgeons and the Society of Transplant Social Work in 2016. Using a discrete choice approach, respondents compared two hypothetical patient profiles and selected one for transplantation. (...) Conditional logistic regression estimated the relative importance of each factor; results were stratified by clinical role and beliefs.ResultsFive hundred and eighy-four transplant providers completed the survey. Social support was the second most influential factor among transplant providers. Providers were most likely to choose a candidate who had social support, always adhered to a medical regimen, and had a 15 years life expectancy with transplant. Psychosocial providers were more influenced by adherence and quality of life compared with medical/surgical providers, who were more influenced by candidates' life expectancy with transplant. For providers concerned with avoiding organ waste, social support was the most influential factor, while it was the least influential for clinicians concerned with fairness.ConclusionsSocial support is highly influential in listing decisions and may exacerbate transplant disparities. Providers’ beliefs and reliance on social support in determining suitability vary considerably, raising concerns about transparency and justice. (shrink)

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, as (...) proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

We argue that the aesthetic domain falls inside the scope of rationality, but does so in its own way. Aesthetic judgment is a stance neither on whether a proposition is to be believed nor on whether an action is to be done, but on whether an object is to be appreciated. Aesthetic judgment is simply appreciation. Correlatively, reasons supporting theoretical, practical and aesthetic judgments operate in fundamentally different ways. The irreducibility of the aesthetic domain is due to the fact that (...) aesthetic judgment is a sensory-affective disclosure of, and responsiveness to, merit: it is a feeling that presents an object, and is responsive to it, as worthy of being liked. Aesthetic judgment is thus shown to be, on the hand, first personal and non-transferable; and, on the other hand, a presentation of reality. We thereby capture what is right in both subjectivist and objectivist conceptions of aesthetic judgment. (shrink)

The aim of the paper is to reassess the prospects of a widely neglected affective conception of the aesthetic evaluation and appreciation of art. On the proposed picture, the aesthetic evaluation and appreciation of art are non-contingently constituted by a particular kind of pleasure. Artworks that are valuable qua artworks merit, deserve, and call for a certain pleasure, the same pleasure that reveals (or at least purports to reveal) them to be valuable in the way that they are, and constitutes (...) their aesthetic evaluation and appreciation. This is why and how art is non-contingently related to pleasure. Call this, the Affective View. While I don’t advance conclusive arguments for the Affective View in this paper, I aim to reassess its prospects by (1) undermining central objections against it, (2) dissociating it from hedonism about the value of artworks (the view that this value is grounded in, and explained by, its possessors’ power to please), and (3) introducing some observations on the practice of art in support of it. Given that the objections I discuss miss their target, and given the observations in support of it, I conclude that the Affective View is worth serious reconsideration. (shrink)

According to tradition, aesthetic value is non-contingently connected to a certain feeling of liking or pleasure. Is that true? Two answers are on offer in the field of aesthetics today: 1. The Hedonist answers: Yes, aesthetic value is non-contingently connected to pleasure insofar as this value is constituted and explained by the power of its possessors to please (under standard conditions). 2. The Non-Affectivist answers: No. At best, pleasure is contingently related to aesthetic value. The aim of this paper is (...) to point to a blind spot in the dialectic between these two standard positions by defending a third neglected answer to the question above, the answer of the Value-Meriting-Pleasure [VMP] advocate. According to this answer, a certain kind of (cognitive and responsive) pleasure is connected to aesthetic value non-contingently, but also non-hedonically. VMP is the view that objects of aesthetic value are non-contingently related to pleasure insofar as they merit a certain kind of pleasure. But, pace the hedonist, those objects are valuable (those that are to be engaged with etc.) neither on account of their capacity to give pleasure nor on account of the hedonic value of the attitude they merit.

This paper challenges the traditional Buddhist positioning of the four jhànas under the category of `concentration meditation' and the premise regarding their secondary and superfluous role in the path of liberation. It seeks to show that the common interpretation of the jhànas as absorption-concentration, attainments that have no liberative value, is incompatible with the teachings of the Pàli Nikàyas. The paper argues few things: First, that one attains the jhànas, not by fixating the mind or being absorbed into a meditation (...) object, but by releasing and letting go of the foothold of the unwholesome mind. Second and related, that the entrance into the first jhàna is the actualization and embodiment of insight practice. Third, that jhànic joy and pleasure has significant liberative importance in the path of liberation; they allow the mind to let go of a rooted and basic tendency that causes suffering: the tendency to desire sensual pleasures.

The study distinguishes between three normative approaches that view diversity in the judiciary as a desirable ideal, outlines their expected empirical implications for judicial decision-making, and tests the implications against data from the Israeli Supreme Court. The “reflecting” approach suggests that diversifying the courts is important mainly as a means of strengthening the public’s confidence in them and does not impact judicial decisions. The “representing” approach asserts that judges serve as representatives of their social sectors. Thus, they tend to rule (...) in favor of their group’s interest only in cases that are relevant to their in-group. The “social background theory” is based on the premise that people of different backgrounds develop distinct worldviews. Hence, social attributes are expected to influence judicial decisions across a wide range of socio-legal issues. The empirical investigation centers on the role of gender and religiosity in judging on five carefully selected socio-legal issues: petitions against the Great Rabbinical Court’s rulings, constitutional disputes in all legal procedures, social welfare cases, and criminal appeals in sex offenses and in drug offenses. The results lend support to social background theory with regard to gender and are consistent with the representing approach with respect to religiosity. I further discuss the limitations and policy implications of the findings. (shrink)

What is the source of aesthetic knowledge? Empirical knowledge, it is generally held, bottoms out in perception. Such knowledge can be transmitted to others through testimony, preserved by memory, and amplified via inference. But perception is where the rubber hits the road. What about aesthetic knowledge? Does it too bottom out in perception? Most say “yes”. But this is wrong. When it comes to aesthetic knowledge, it is appreciation, not perception, where the rubber hits the road. The ultimate source of (...) aesthetic knowledge is feeling. In this essay, we articulate and defend the very idea of affective knowledge and reveal aesthetic knowledge to be a species of the genus. We then show how the view resolves a thorny problem that has bedeviled aesthetic epistemologists: how to reconcile the seemingly direct character of aesthetic knowledge with the possibility of acquiring such knowledge from criticism. One learns from criticism, we argue, when it guides one’s engagement with an object so that one can appreciate it in virtue of those of its features that render it worthy of appreciation. (shrink)

There is a debate about whether particular properties are for Aristotle non-recurrent and trope-like individuals or recurrent universals. I argue that Physics I.7 provides evidence that he took non-substantial particulars to be neither; they are instead non-recurrent modes. Physics I.7 also helps show why this matters. Particular properties must be individual modes in order for Aristotle to preserve three key philosophical commitments: that objects of ordinary experience are primary substances, that primary substances undergo genuine change, and that primary substances are (...) ontologically fundamental.

Equine-Facilitated Psychotherapy is widely used, and the uses to which it can be put are still being developed. However, existing knowledge about this field is insufficient, and most of the research suffers from methodological problems that compromise its rigor. This review will explore research into the linked fields of Animal-Assisted Therapy and Equine-Assisted Activities/Therapies related to physical health. Existing knowledge of mental, emotional, and social applications of EAA/T is presented. Evaluation studies in the subfield suggest that people benefit from interventions (...) with horses. However, these studies suffer from fundamental problems, such as small sample size and lack of control groups. Naturalistic inquiry about theoretical aspects highlights the fundamental role that human-horse relations play in EAA/T, but these studies exhibit deficiencies in theory development. A multimethod approach could promote knowledge development for EFP. Suggestions for future research concern methodological solutions to improve evaluation studies, use of grounded theory method to develop theory, as well as applying attachment theory to the human-horse context, which may offer insight about the underlying processes for change.

The booming popularity of the Internet, and particularly increasing use of personal Web sites, social networking sites, and blogging, raises questions regarding the ethical use of psychology graduate students' personal online information for academic purposes.

Finally, I make several recommendations for graduate training faculty and graduate students as they consider placing and using information on and from the Internet. (shrink)

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other (...) populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

Until very recently, there has been no discussion of aesthetic agency. This is likely because aesthetics has traditionally focused not on action, but on appreciation, while the standard approach identifies ‘agency’ with the will, and, more specifically, with the capacity for intentional action. In this paper, I argue, first, that this identification is unfortunate since it fails to do justice to the fact that we standardly attribute beliefs, emotions, desires, and other conative and affective attitudes that aren’t formed ‘at will,’ (...) including aesthetic appreciation, to people’s agency. Fortunately, we need not abide by this Practical Approach, but can develop an alternative: the Authority Approach to rational agency, which does justice to the widespread practice of rationally assessing, reactively responding to, and holding people responsible for non-voluntary attitudes. This is very good news for aesthetics since, I argue additionally, any account of aesthetic agency that accepts the Practical Approach, and focuses on aesthetic actions fails to provide a genuine notion of aesthetic agency. For we have no handle on what counts as aesthetic actions independently of these actions’ relation to appreciation: actions are “aesthetic” only derivatively insofar as they center around those that merit (dis)appreciation. For this reason, we have genuine aesthetic agency only if we can exercise agency in acts of the rational-affective capacity for appreciation, which differs from the will. The Authority Approach allows us to explain how we exercise agency in aesthetic appreciations, thus equipping us with a genuine conception of aesthetic agency. (shrink)

In this paper I argue that Aristotle's understanding of mathematical continuity constrains the mathematical ontology he can consistently hold. On my reading, Aristotle can only be a mathematical abstractionist of a certain sort. To show this, I first present an analysis of Aristotle's notion of continuity by bringing together texts from his Metaphysica and Physica, to show that continuity is, for Aristotle, a certain kind of per se unity, and that upon this rests his distinction between continuity and contiguity. Next (...) I argue briefly that Aristotle intends for his discussion of continuity to apply to pure mathematical objects such as lines and figures, as well as to extended bodies. I show that this leads him to a difficulty, for it does not at first appear that the distinction between continuity and contiguity can be preserved for abstract mathematicals. Finally, I present a solution according to which Aristotle's understanding of continuity can only be saved if he holds a certain kind of mathematical ontology. (shrink)

Aristotle’s concept of subject, or hypokeimenon, has been understudied in scholarship, in part because, since Aristotle associates it with his concept of ousia or substance, discussion of hypokeimenon is often eclipsed by that of substance. It is often thought that Aristotle introduces hypokeimenon as the criterion for being a substance in his Categories. In this essay I argue that he does not, thus calling into question some entrenched views about Aristotelian substance. Divorcing hypokeimenon from substance in this way emphasizes the (...) need for an account of hypokeimenon in its own right. In this essay I also begin this work by using an often overlooked pointer in Categories towards a discussion in An. Po., in whose context Aristotle's logical notion of hypokeimenon begins to become more clear. (shrink)
