Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of sensory experiences and their (...) capacity to provide access to reality, this article challenges the standard categories through which most arguments in this debate have been framed to date. Drawing on the underexplored case of olfaction, I first show how the details of the perception process determine the modalities of sensory experiences. I specifically examine the role of measurement and analyze its influence on the characterization of perceptions in olfaction. My aim is to argue for an understanding of perception through a process view, rather than one pertaining to objects and properties of objects. (shrink)

Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical measurements do: the problem of coordination and the problem of standardization. These problems are addressed through the process of “epistemic iteration,” for all measurements. We also argue for distinguishing the problem of standardization from the problem of coordination. To exemplify our claims, we (...) draw on olfactory performance tests, especially studies linking olfactory decline to neurodegenerative disorders. (shrink)

Is the sense of smell a source of aesthetic perception? Traditional philosophical aesthetics has centered on vision and audition but eliminated smell for its subjective and inherently affective character. This article dismantles the myth that olfaction is an unsophisticated sense. It makes a case for olfactory aesthetics by integrating recent insights in neuroscience with traditional expertise about flavor and fragrance assessment in perfumery and wine tasting. My analysis concerns the importance of observational refinement in aesthetic experience. I argue that the (...) active engagement with stimulus features in perceptual processing shapes the phenomenological content, so much so that the perceptual structure of trained smelling varies significantly from naive smelling. In a second step, I interpret the processes that determine such perceptual refinement in the context of neural decision-making processes, and I end with a positive outlook on how research in neuroscience can be used to benefit philosophical aesthetics.

How much does stimulus input shape perception? The common-sense view is that our perceptions are representations of objects and their features and that the stimulus structures the perceptual object. The problem for this view concerns perceptual biases as responsible for distortions and the subjectivity of perceptual experience. These biases are increasingly studied as constitutive factors of brain processes in recent neuroscience. In neural network models the brain is said to cope with the plethora of sensory information by predicting stimulus regularities (...) on the basis of previous experiences. Drawing on this development, this chapter analyses perceptions as processes. Looking at olfaction as a model system, it argues for the need to abandon a stimulus-centred perspective, where smells are thought of as stable percepts, computationally linked to external objects such as odorous molecules. Perception here is presented as a measure of changing signal ratios in an environment informed by expectancy effects from top-down processes. (shrink)

Scientific models share one central characteristic with fiction: their relation to the physical world is ambiguous. It is often unclear whether an element in a model represents something in the world or presents an artifact of model building. Fiction, too, can resemble our world to varying degrees. However, we assign a different epistemic function to scientific representations. As artifacts of human activity, how are scientific representations allowing us to make inferences about real phenomena? In reply to this concern, philosophers of (...) science have started analyzing scientific representations in terms of fictionalization strategies. Many arguments center on a dyadic relation between the model and its target system, focusing on structural resemblances and “as if” scenarios. This chapter provides a different approach. It looks more closely at model building to analyze the interpretative strategies dealing with the representational limits of models. How do we interpret ambiguous elements in models? Moreover, how do we determine the validity of model-based inferences to information that is not an explicit part of a representational structure? I argue that the problem of ambiguous inference emerges from two features of representations, namely their hybridity and incompleteness. To distinguish between fictional and non-fictional elements in scientific models my suggestion is to look at the integrative strategies that link a particular model to other methods in an ongoing research context. To exemplify this idea, I examine protein modeling through X-ray crystallography as a pivotal method in biochemistry. (shrink)

A recent and growing discussion in philosophy addresses the construction of models and their use in scientific reasoning by comparison with fiction. This comparison helps to explore the problem of mediated observation and, hence, the lack of an unambiguous reference of representations. Examining the usefulness of the concept of fiction for a comparison with non-denoting elements in science, the aim of this paper is to present reasonable grounds for drawing a distinction between these two kinds of representation. In particular, my (...) account will suggest a demarcation between fictional and non-fictional discourse as involving two different ways of interpreting representations. This demarcation, leading me to distinguish between fictional and non-fictional forms of enquiry, will provide a useful tool to explore to what extent the descriptions given by a model can be justified as making claims about the world and to what degree they are a consequence of the model’s particular construction.

Short piece for The Philosophers' Magazine on why philosophers should pay attention to olfaction.

This article provides an overview of the contributions to philosophy of Nigerian philosopher Sophie Bọ´sẹ`dé Olúwọlé. The first woman to earn a philosophy PhD in Nigeria, Olúwọlé headed the Department of Philosophy at the University of Lagos before retiring to found and run the Centre for African Culture and Development. She devoted her career to studying Yoruba philosophy, translating the ancient Yoruba Ifá canon, which embodies the teachings of Orunmila, a philosopher revered as an Óríṣá in the Ifá pantheon. Seeing (...) his works as examples of secular reasoning and argument, she compared Orunmila's and Socrates' philosophies and methods and explored similarities and differences between African and European philosophies. A champion of African oral traditions, Olúwọlé argued that songs, proverbs, liturgies, and stories are important sources of African responses to perennial philosophical questions as well as to contemporary issues, including feminism. She argued that the complementarity that ran throughout Yoruba philosophy guaranteed women's rights and status, and preserved an important role for women, youths, and foreigners in politics.

The resercher Ann Talbot presents in this book one of the more complex and in-depth studies ever written about the influence of travel literature on the work of the British philospher John Locke (1632-1704). At the end of the 18th century the study of travel literature was an alternative to academic studies. The philosopher John Locke recommended with enthousiasm these books as a way to comprehend human understanding. Several members of the Royal Society like John Harris (1966-1719) affirmed that the (...) learning that could be obtained through these books was different from the one that provided the educative system of that time. Travel literature could make see the source of the ignorance of the ancients; it stressed the curiosities and extraordinary facts and led to a revision of beliefs and scientific theories of the ancient world. Besides the account of a broad diversity of sujects contributed to the creation of matters of fact, and this was important in order to put rational limits to the descriptions of the world that were commonly accepted.

The central argument of Ann Cahill’s Overcoming Objectification is that the concept of sexual objectification should be replaced by Cahill’s concept of derivatization in order to better capture the wrongness of degrading images and practices without depending on an objectionably narrow and disembodied conception of self. To derivatize someone is not to treat her as a non-person, but rather to treat her as a derivative person, reducing her to an aspect of another’s being. Although not perfect, Cahill’s approach advances the (...) conversation about what we should find objectionable in certain types of sexual representations and interactions by helping us to talk about sex in a way that does not start from the presupposition that physical expressions of sexuality are inherently debasing. I describe the thesis of the book, how I used it in my Philosophy and Women course, and some criticisms that I have and that arose from class discussion. (shrink)

In philosophical circles, Electress Sophie of Hanover (1630-1714) is known mainly as the friend, patron, and correspondent of Leibniz. While many scholars acknowledge Sophie's interest in philosophy, some also claim that Sophie dabbled in philosophy herself, but did not do so either seriously or competently. In this paper I show that such a view is incorrect, and that Sophie did make interesting philosophical contributions of her own, principally concerning the nature of mind and thought.

The presented study introduces a new theoretical model of collapse for social, cultural, or political systems. Based on the current form of quantum anthropology conceptualized by Heidi Ann Russell, further development of this field is provided. The new theoretical model is called the spiral model of collapses, and is suggested to provide an analytical framework for collapses in social, cultural, and political systems. The main conclusions of this study are: 1) The individual crises in the period before a collapse of (...) social, cultural, and political systems form the trajectory of a conical helix similar to a vortex. 2) The occurrences of crises in the period before a collapse have the shape of the trajectory on the surface of the circular cone with a convex wall narrowing up to its peak. The shape of this cone is based on the Fibonacci sequence coiled into the three-dimensional space. 3) The constant circular movement along the trajectory of crises can occur in exceptional situations in the development of social, cultural, and political systems; however, such a state is always temporary. In such cases, the trajectory of the crisis does not follow the Fibonacci sequence, but the shape of a regular helix. Remaining on the trajectory of a regular helix in the long-term is highly improbable for social, cultural, and political systems. 4) The creation of new potentialities after the final collapse of a system is explained by the conception of topological inversion, when the heretofore embodied part of the energy-information field returns to the global, wave-particle energy-information potential. 5) The global, wave-particle energy-information potential is a source of energy-information for future embodiments in the sense of the future collapses of wave functions.

Oluwole zelf werd geboren in het dorp Igbara Oke in de naburige staat Ondo, waar zij ook haar lagere en middelbare school doorliep. In 1964 trouwde zij met een eveneens Nigeriaanse wetenschapper. Ze vertrok nog in hetzelfde jaar naar Moskou, waar haar man (...) een baan kreeg aangeboden bij de Verenigde Naties. Vanwege taalproblemen vertrokken beiden na een jaar naar Duitsland, waar zij Duits studeerden aan de Universiteit in Keulen. Kort nadat zij in 1966 verhuisde naar de Verenigde Staten, scheidde Oluwole van haar man omdat deze haar verdere studies dwarsboomde. Oluwole keerde terug naar Nigeria waar zij aan de Universiteit van Lagos een studie filosofie begon. In de periode 1968-1970 doceerde Oluwole op een middelbare school in haar thuisstaat Ondo. Daarna keerde zij terug naar de universiteit van Lagos, waar zij werkzaam was als studentassistente en ondertussen afstudeerde. Oluwole werd als promovenda toegelaten op de universiteit van Ibadan. In 1984 behaalde zij als eerste student in sub-Sahara Afrika een doctorstitel in de filosofie. Hoewel Oluwoles filosofische carrière een aanvang nam met de studie van westerse meta-ethiek, besloot zij zich na het behalen van haar doctorstitel verder te ontwikkelen in de richting van de Afrikaanse filosofie.

This is basically a paper about artistic evaluation and how multiple interpretations can give rise to inconsistent and conflicting meanings. Images like Joel-Peter Witkin’s First Casting for Milo (2004) challenge the viewer to look closely, understand the formal properties at work, and then extract a meaning that ultimately asks, Is the model exploited or empowered? Is Karen Duffy, pictured here, vulnerable and “enfreaked” or is she potentially subversive, transgressive, and perhaps self-empowered? I will offer an argument in agreement with artist/author/ (...) performer Ann Millett-Gallant that favors the latter interpretation, but will augment and complicate the issue by also introducing a pointed question or two taken from a recent analysis by Cynthia Freeland on objectification. I judge the works by photographer Joel-Peter Witkin to be representations of disabled persons who are empowered through agency and pride, but I also worry about the risk of multiple, conflicting interpretations on the part of viewers who do not, or cannot, entertain such enlightened readings. Like second wave feminist views about pornography that depicted women in demeaning ways, or feminist critiques of Judy Chicago’s The Dinner Party , Witkin’s photos can be judged as potentially offensive. But they are also objects of beauty—both in terms of aesthetic properties (they are magnificent studies in black and white, shadows, the human body, with many classical references) and because of the feeling of beauty and pride felt by the posers, who become performers of their own beauty and pride. I argue that beauty trumps offensiveness. Pride wins. But I’m not sure that everyone will agree. (shrink)

Sophie Roux confronte la critique du « sokalisme » qu’on trouve dans La Querelle des imposteurs d’Yves Jeanneret et la manière dont Impostures intellectuelles dessine le partage entre « littéraires » et « scientifiques ».

In this essay, I read Woolf’s To the Lighthouse together with philosopher Cora Diamond’s writing on literature and moral life, writing marked by her inheritance from Wittgenstein. I first attend to Woolf’s commitment (one she shares with Wittgenstein) to grappling with what I take to be signature issues of modernism: question, quest, and a longing for vision or revised understanding as a way of confronting the difficulty of reality. I then probe Woolf’s engagement with these issues by reading her novel (...) in light of Diamond’s essay “The Difficulty of Philosophy and the Difficulty of Reality.” Diamond’s insights about literature’s capacity for ethical instruction, and her discussion in that essay of the experience of an ordinary sublime so painful or astonishing that it resists our understanding and categories of thought, illuminate a new philosophical context in which to understand more clearly and profoundly the stakes and aims of Woolf’s novel. Reading Woolf alongside Diamond also prompts us to recognize important ways in which matters that lie at the heart of To the Lighthouseintersect with the Wittgensteinian preoccupations that inform Diamond’s own thinking—concerns about the ethics of difficulty; skepticism about what other people think and feel; the search for communicative and existential clarity; the capacity of literature and fairy tale to convey a sense of beauty or of the “terrible” in the world; the status of expressions of our ethical experience as necessarily nonsensical; a longing for the sense of wholeness, transformative understanding, wonder, safety, and peace to stave off illusion or despair. One important subsidiary effect of looking at Woolf and Diamond together is that doing so also allows us to make significant oblique connections between Woolf’s thinking and Wittgenstein’s, connections that continue to bring into focus the philosophical sympathies that attest to the mutual relevance of their peculiar brands of modernism.

Mon projet de “monstrer” Diderot consiste à examiner le monstre comme étant une figure privilégiée de son texte, mais aussi comme un moyen d’éclairer certains aspects de sa pensée philosophique et poétique. Pour Diderot, les monstres en tant qu’êtres hybrides appartenant à différents règnes, permettent de montrer la continuité de la matière nécessaire à son matérialisme. La monstruosité est aussi l’action normale de la nature ainsi que le pouvoir évolutif et le principe créatif d’une matière toujours en action nécessaires à (...) sa vision transformiste du monde. Comme les philosophes du siècle des lumières, Diderot démystifier le monstre en le montrant sous son aspect scientifique plutôt que produit du mythe ou de l’imagination maternelle. Mais même si les monstres du Rêve de d’Alembert se veulent scientifiques, ils sont cependant le plus souvent des constructions du texte, comme dans le cas des catachrèses du bipède déformé, le faux manchot, ou la mouvance des genres du chiasme de Mademoiselle de l’Espinasse. Diderot retourne en ce sens à une catégorie de l’imagination monstrueuse, sous la forme de fables scientifiques. Prenant forme dans le texte, les monstres sont enfin eux-mêmes opérateurs de texte, tels que la repousse prolifique du texte polypeux, ou la copulation textuelle sur le mode du chèvre-pied. (shrink)

Standard accuracy-based approaches to imprecise credences have the consequence that it is rational to move between precise and imprecise credences arbitrarily, without gaining any new evidence. Building on the Educated Guessing Framework of Horowitz (2019), we develop an alternative accuracy-based approach to imprecise credences that does not have this shortcoming. We argue that it is always irrational to move from a precise state to an imprecise state arbitrarily, however it can be rational to move from an imprecise state to a (...) precise state arbitrarily.

In her recent paper ‘The Epistemology of Propaganda’ Rachel McKinnon discusses what she refers to as ‘TERF propaganda’. We take issue with three points in her paper. The first is her rejection of the claim that ‘TERF’ is a misogynistic slur. The second is the examples she presents as commitments of so-called ‘TERFs’, in order to establish that radical (and gender critical) feminists rely on a flawed ideology. The third is her claim that standpoint epistemology can be used to establish (...) that such feminists are wrong to worry about a threat of male violence in relation to trans women. In Section 1 we argue that ‘TERF’ is not a merely descriptive term; that to the extent that McKinnon offers considerations in support of the claim that ‘TERF’ is not a slur, these considerations fail; and that ‘TERF’ is a slur according to several prominent accounts in the contemporary literature. In Section 2, we argue that McKinnon misrepresents the position of gender critical feminists, and in doing so fails to establish the claim that the ideology behind these positions is flawed. In Section 3 we argue that McKinnon’s criticism of Stanley fails, and one implication of this is that those she characterizes as ‘positively privileged’ cannot rely on the standpoint-relative knowledge of those she characterizes as ‘negatively privileged’. We also emphasize in this section McKinnon’s failure to understand and account for multiple axes of oppression, of which the cis/trans axis is only one. (shrink)

Suppose that Ann says, “Keith knows that the bank will be open tomorrow.” Her audience may well agree. Her knowledge ascription may seem true. But now suppose that Ben—in a different context—also says “Keith knows that the bank will be open tomorrow.” His audience may well disagree. His knowledge ascription may seem false. Indeed, a number of philosophers have claimed that people’s intuitions about knowledge ascriptions are context sensitive, in the sense that the very same knowledge ascription can seem true (...) in one conversational context but false in another. This purported fact about people’s intuitions serves as one of the main pieces of evidence for epistemic contextualism. (shrink)

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the thesis. Our argument (...) is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

Several theorists have observed that attitude reports have what we call “revisionist” uses. For example, even if Pete has never met Ann and has no idea that she exists, Jane can still say to Jim ‘Pete believes Ann can learn to play tennis in ten lessons’ if Pete believes all 6-year-olds can learn to play tennis in ten lessons and it is part of Jane and Jim’s background knowledge that Ann is a 6-year-old. Jane’s assertion seems acceptable because the claim (...) she reports Pete as believing is entailed by Pete’s beliefs if they are revised in light of Jane and Jim’s background knowledge. We provide a semantic theory of revisionist reports based on this idea. We observe that the admissible “revisions” are limited in a striking way. Jane cannot say ‘Pete thinks Ann is a 6-year-old and can play tennis in ten lessons’ in the same context that she can say ‘Pete believes Ann can learn to play tennis ten lessons’, even though this too follows from Jane and Jim’s background knowledge together with what Pete believes. Our theory predicts the infelicity of these latter reports. It also has the resources to predict the truth of “exported” attitude reports and casts the relationship between these reports and “singular thought” in a new light. We conclude by discussing how revisionist reports make trouble for a simplistic view of the connection between the relations expressed by attitude verbs in natural language and the relations of most interest to philosophers of mind and cognitive science.

We advocate and develop a states-based semantics for both nominal and adjectival confidence reports, as in "Ann is confident/has confidence that it's raining", and their comparatives "Ann is more confident/has more confidence that it's raining than that it's snowing". Other examples of adjectives that can report confidence include "sure" and "certain". Our account adapts Wellwood's account of adjectival comparatives in which the adjectives denote properties of states, and measure functions are introduced compositionally. We further explore the prospects of applying these (...) tools to the semantics of probability operators. We emphasize three desirable and novel features of our semantics: (i) probability claims only exploit qualitative resources unless there is explicit compositional pressure for quantitative resources; (ii) the semantics applies to both probabilistic adjectives (e.g., "likely") and probabilistic nouns (e.g., "probability"); (iii) the semantics can be combined with an account of belief reports that allows thinkers to have incoherent probabilistic beliefs (e.g. thinking that A & B is more likely than A) even while validating the relevant purely probabilistic claims (e.g. validating the claim that A & B is never more likely than A). Finally, we explore the interaction between confidence-reporting discourse (e.g., "I am confident that...") and belief-reports about probabilistic discourse (e.g.,"I think it's likely that..").

In an influential paper, L. A. Paul argues that one cannot rationally decide whether to have children. In particular, she argues that such a decision is intractable for standard decision theory. Paul's central argument in this paper rests on the claim that becoming a parent is ``epistemically transformative''---prior to becoming a parent, it is impossible to know what being a parent is like. Paul argues that because parenting is epistemically transformative, one cannot estimate the values of the various outcomes of (...) a decision whether to become a parent. In response, we argue that it is possible to estimate the value of epistemically transformative experiences. Therefore, there is no special difficulty involved in deciding whether to undergo epistemically transformative experiences. Insofar as major life decisions do pose a challenge to decision theory, we suggest that this is because they often involve separate, familiar problems. (shrink)

William James famously tells us that there are two main goals for rational believers: believing truth and avoiding error. I argues that epistemic consequentialism—in particular its embodiment in epistemic utility theory—seems to be well positioned to explain how epistemic agents might permissibly weight these goals differently and adopt different credences as a result. After all, practical versions of consequentialism render it permissible for agents with different goals to act differently in the same situation. -/- Nevertheless, I argue that epistemic consequentialism (...) doesn’t allow for this kind of permissivism and goes on to argue that this reveals a deep disanalogy between decision theory and the formally similar epistemic utility theory. This raises the question whether epistemic utility theory is a genuinely consequentialist theory at all. (shrink)

Johnston famously argued that the colors are, more or less inclusively speaking, dispositions to cause color experiences by arguing that this view best accommodates his five proposed core beliefs about color. Since then, Campbell, Kalderon, Gert, Benbaji, and others, have all engaged with at least some of Johnston’s proposed core beliefs in one way or another. Which propositions are core beliefs is ultimately an empirical matter. We investigate whether Johnston’s proposed core beliefs are, in fact, believed by assessing the agreement/disagreement (...) of non-philosophers with them. Two experiments are run each with large sample sizes, the second designed to address criticisms of the first. We find that non-philosophers mostly agree with the proposed core beliefs, but that they agree with some more than others. (shrink)

According to Russellianism (or Millianism), the two sentences ‘Ralph believes George Eliot is a novelist’ and ‘Ralph believes Mary Ann Evans is a novelist’ cannot diverge in truth-value, since they express the same proposition. The problem for the Russellian (or Millian) is that a puzzle of Kaplan’s seems to show that they can diverge in truth-value and that therefore, since the Russellian holds that they express the same proposition, the Russellian view is contradictory. I argue that the standard Russellian appeal (...) to “ways of thinking” or “propositional guises” is not necessary to solve the puzzle. Rather than this retrograde concession to Fregeanism, appeal should be made to second-order belief. The puzzle is solved, and the contradiction avoided, by maintaining that both sentences are indeed true in addition to the sentence ‘Ralph (mistakenly) believes that he does not believe Mary Ann Evans/George Eliot is a novelist’.

The feminist charge that Michel Foucault's work in general and his history of sexuality in particular are masculinist, sexist, and reflect male biases vexes feminist philosophers of disability who believe his claims about (for instance) the constitution of subjects, genealogy, governmentality, discipline, and regimes of truths imbue their feminist analyses of disability and ableism with complexity and richness, as well as inspire theoretical sophistication and intellectual rigor in the fields of philosophy of disability and disability studies more generally. No aspect (...) of Foucault's corpus has been more consistently subjected to the charges of masculinism and male bias than his example of the nineteenth-century farmhand Charles Jouy who, at about forty years of age, engaged in sexual activity with a girl, Sophie Adam, was reported to authorities, and subsequently was incarcerated in Maréville for the rest of his days. My central aim in this paper is to interrupt the momentum of the accepted feminist interpretation of the Jouy case by advancing a feminist perspective on Jouy's identity and the incidents involving Jouy and Adam that takes seriously insights derived from philosophy of disability and critical disability theory and history.

The use of writing or journaling as a tool toward healing is becoming increasingly accepted in the vernacular of healing litanies. Reference books, personal narratives, and research on the effects of writing on healing psychological discomfort are abundant. Heal Yourself with Writing, written by screenwriter Catherine Ann Jones, and published in 2013, won a Nautilus Book Award for 2014. The following review reflects a book that is a well-thought journey through the steps of intentional or focused writing for the express (...) purpose of moving from living from beliefs and thoughts that do not serve healthy wholeness or fullness of life, into living more freely and more authentically.

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Color relationalism holds that the colors are constituted by relations to subjects. The introspective rejoinder against this view claims that it is opposed to our phenomenally-informed, pre-theoretic intuitions. The rejoinder seems to be correct about how colors appear when looking at how participants respond to an item about the metaphysical nature of color but not when looking at an item about the ascription of colors. The present article expands the properties investigated to sound and taste and inspects the mentioned asymmetry, (...) with a particular focus on the principle of charity. Using a metaphysical item, we find that color and sound are no different from shape, our control for a clearly anti-relational property. Taste, on the other hand, is no different from likability, our control for a clearly relational property. Importantly, we find that the disparity between metaphysical and ascription items is due to participants using a principle of charity to interpret disagreement cases such that both parties can be correct.

Inclusive design prescribes addressing the needs of the widest possible audience in order to consider human differences. Taking differences seriously, however, may imply severely restricting “the widest possible audience”. In confronting this paradox, we investigate to what extent Rawls’ theory of justice as fairness applies to design. By converting the paradox into the question of how design can be fair, we show that the demand for equitability shifts from the design output to the design process. We conclude that the two (...) main questions about justice find application in design: the question about the standards of justice and the question about its metrics. We endorse a Rawlsian approach to the former, while some revision may be due regarding the latter. (shrink)
