Comparative political philosophy and theories.

On various philosophical theories and concepts.

Evidence-based medicine has been the subject of much controversy within and outside the field of medicine, with its detractors characterizing it as reductionist and authoritarian, and its proponents rejecting such characterization as a caricature of the actual practice. At the heart of this controversy is a complex linguistic and social process that cannot be illuminated by appealing to the semantics of the modifier evidence-based. The complexity lies in the nature of evidence as a basic concept that circulates in both expert (...) and non-expert spheres of communication, supports different interpretations in different contexts, and is inherently open to contestation. We outline a new methodology that combines a social epistemological perspective with advanced methods of corpus linguistics and elements of conceptual history to investigate this and other basic concepts that underpin the practice and ethos of modern medicine. The potential of this methodology to offer new insights into controversies such as those surrounding EBM is demonstrated through a case study of the various meanings supported by evidence and based, as attested in a large electronic corpus of online material written by non-experts as well as a variety of experts in different fields, including medicine.

Ethical challenges concerning climate change most often involve two issues that are tightly connected. The first is considerations about the just distribution of entitlements and burdens, and the second concerns the fair differentiation of responsibilities. The distribution of entitlements and burdens can be assessed by relying on one or combinations of principles of climate justice. Although the fairness of any differentiation of responsibilities must rely on these principles of justice, the applicability of these principles and the demands they make strongly (...) depend on the agents bearing the responsibility and what policy domains are at issue. Not all agents can be ascribed the same responsibilities, and not all measures for climate action can or should be realized by the same differentiation of responsibilities. This paper examines how the principle of common but differentiated responsibilities depends on the domain and level of climate policy. It is not only the subjects of responsibility that may change, depending on whether mitigation, adaptation, loss and damage, or geoengineering policy is at issue. The different policy domains also determine different objects of responsibility. Since the responsibility bearers are embedded in complex nets of responsibilities, the level of climate policy defines different institutions and principles of accountability. Common but differentiated responsibilities is not only the starting-point of climate justice but also shapes what combinations of principles of justice are most appropriate, depending on the domain and level of climate policy at scrutiny.

Berkeley’s likeness principle is the claim that “an idea can be like nothing but an idea”. The likeness principle is intended to undermine representationalism: the view (that Berkeley attributes to thinkers like Descartes and Locke) that all human knowledge is mediated by ideas in the mind which represent material objects. Yet, Berkeley appears to leave the likeness principle unargued for. This has led to several attempts to explain why Berkeley accepts it. In contrast to ‘metaphysical’ and ‘epistemological’ interpretations available in (...) the literature, in this paper I defend a ‘conceptual’ interpretation. I argue that Berkeley accepts the likeness principle on the basis of (i) his commitment to the transparency of ideas, and (ii) his account of resemblance which he sets out in his works on vision. Thus, I provide an explanation for Berkeley’s reasons for accepting the likeness principle which, appropriately, focuses on his views concerning ideas and likeness. (shrink)

We describe how the set of tools, practices, and social relations known as “precision agriculture” is defined, promoted, and debated. To do so, we perform a critical discourse analysis of popular and trade press websites. Promoters of precision agriculture champion how big data analytics, automated equipment, and decision-support software will optimize yields in the face of narrow margins and public concern about farming’s environmental impacts. At its core, however, the idea of farmers leveraging digital infrastructure in their operations is not (...) new, as agronomic research in this vein has existed for over 30 years. Contemporary discourse in precision ag tends to favour emerging digital technologies themselves over their embeddedness in longstanding precision management approaches. Following several strands of science and technology studies research, we explore what rhetorical emphasis on technical innovation achieves, and argue that this discourse of novelty is a reinvention of precision agriculture in the context of the growing “smart” agricultural economy. We overview six tensions that remain unresolved in this promotional rhetoric, concerning the definitions, history, goals, adoption, uses, and impacts of precision agriculture. We then synthesize these in a discussion of the extent to which digital tools are believed to displace farmer decision-making and whether digital agriculture addresses the biophysical heterogeneity of farm landscapes or land itself has become an “experimental technology”—a way to advance the general development of artificial intelligence. This discussion ultimately helps us name a larger dilemma: that the smart agricultural economy is perhaps less about supporting land and its stewards than promising future tech and profits. (shrink)

Configural face processing precedes featural face processing under the face-attended condition, but their temporal sequence in the absence of attention is unclear. The present study investigated this issue by recording visual mismatch negativity, which indicates the automatic processing of visual information under unattended conditions. Participants performed a central cross size change detection task, in which random sequences of faces were presented peripherally, in an oddball paradigm. In Experiment 1, configural and featural faces were presented infrequently among original faces. In Experiment (...) 2, configural faces were presented infrequently among featural faces, or vice versa. The occipital-temporal vMMN emerged in the 200–360 ms latency range for configural, but not featural, face information. More specifically, configural face information elicited a substantial vMMN component in the 200–360 ms range in Experiment 1. This result was replicated in the 320–360 ms range in Experiment 2, especially in the right hemisphere. These results suggest that configural, but not featural, face information is associated with automatic processing and provides new electrophysiological evidence for the different mechanisms underlying configural and featural face processing under unattended conditions.

Lies and deception are often used in the care for demented elderly and often with the best intentions. However, there is a strong moral presumption against all forms of lying and deceiving. The goal of this article is to examine and evaluate concrete examples of deception and lies in dementia care, while addressing some fundamental issues in the process.It is argued that because dementia slowly diminishes the capacities one needs to distinguish between truths and falsehoods, the ability to be lied (...) to also disappears. When the moral reasons to reject lying are explored, it becomes clear that most of them also hold where demented patients are concerned, though this also depends on the capacities of the patient. Lying, though prima facie wrong, can sometimes be justified with an appeal to well-being. The relationship between well-being and the truth is further explored. Two examples of deceiving demented patients for reasons of beneficence are discussed, from which it can be concluded that although in some cases beneficent lies or deception will not enhance patients’ well-being, there are circumstances in which they do. In general, methods that enhance the well-being of the patient without deception or lies should be favored above options that use deceit, and methods of getting the truth across without hurting the patient should be favored above blunt honesty. Finally, it is important to note that not only the patient but also the nursing and medical staff can be affected by the use of lies and deception. (shrink)

Perceptual load plays a critical role in identification and awareness of stimuli. Given the differences in emotion–attention interactions, we investigated the perception of distractor emotional faces in two different load conditions under divided attention with a task based on the inattentional blindness paradigm. Participants performed a low- or high-load task with a string of letters presented against a happy, sad or neutral face (in a circular form) as the background. Participants were asked to identify the face that appeared in the (...) critical trial. Results indicate an interaction between emotion and load. First, identification of faces with happy expression was better than chance and unaffected by load. Second, performance was worse than chance for faces with sad expression in the high-load condition, indicating inhibition of unattended sad distractor faces in the critical trial. This indicates that inhibitory processes during a difficult attentional task under divided attention influence subsequent perception of distractor stimuli especially sad faces. The results have implications for the theories of selective attention as well as the role of emotions in conscious perception. (shrink)

There seems to be a strong sentiment in pre-philosophical moral thought that actions can be morally valuable without at the same time being morally required. Yet Kant, who takes great pride in developing an ethical system firmly grounded in common moral thought, makes no provision for any such extraordinary acts of virtue. Rather, he supports a classification of actions as either obligatory, permissible or prohibited, which in the eyes of his critics makes it totally inadequate to the facts of morality. (...) The related idea of uncommonly grand and noble deeds is frequently dismissed by Kant as high-.own emotional nonsense. Such considerations give rise to the fear that actions intuitively classed as morally commendable but not required must be re-classified as commands of duty by Kant, making his ethical theory as unbearably demanding as direct utilitarianism. The paper divides into three sections: (1) an examination of the nature of moral goodness from a meta-ethical angle that introduces some passages from Kant's writings presenting strong theoretical evidence against the case for supererogatory action; (2) a critique of Thomas Hill's suggestion that within the category of wide duty we can accommodate some of the main features of actions classified as supererogatory in other ethical systems; concluding that, contra Hill, there are no actions of wide duty that can be so characterized in any significant sense; and (3) a final discussion of the problem of how demanding the requirements of Kantian ethical theory really are.

A powerful objection to subject-sensitive invariantism concerns various ‘strange-but-true’ conditionals. One popular response to this objection is to argue that strange-but-true conditionals pose a problem for non-sceptical epistemological theories in general. In the present paper, it is argued that strange-but-true conditionals are not a problem for contextualism about ‘know’. This observation undercuts the proposed defence of SSI, and supplies a surprising new argument for contextualism.

In 2008, a group of researchers publicly released profile data collected from the Facebook accounts of an entire cohort of college students from a US university. While good-faith attempts were made to hide the identity of the institution and protect the privacy of the data subjects, the source of the data was quickly identified, placing the privacy of the students at risk. Using this incident as a case study, this paper articulates a set of ethical concerns that must be addressed (...) before embarking on future research in social networking sites, including the nature of consent, properly identifying and respecting expectations of privacy on social network sites, strategies for data anonymization prior to public release, and the relative expertise of institutional review boards when confronted with research projects based on data gleaned from social media.

Unlike first-person Moorean sentences, it’s not always awkward to assert, “p, but you don’t know that p.” This can seem puzzling: after all, one can never get one’s audience to know the asserted content by speaking thus. Nevertheless, such assertions can be conversationally useful, for instance, by helping speaker and addressee agree on where to disagree. I will argue that such assertions also make trouble for the growing family of views about the norm of assertion that what licenses proper assertion (...) is not the initiating epistemic position of the speaker but the resulting epistemic position of the audience.

This paper analyzes correspondence between Reichenbach and Einstein from the spring of 1926, concerning what it means to ‘geometrize’ a physical field. The content of a typewritten note that Reichenbach sent to Einstein on that occasion is reconstructed, showing that it was an early version of §49 of the untranslated Appendix to his Philosophie der Raum-Zeit-Lehre, on which Reichenbach was working at the time. This paper claims that the toy-geometrization of the electromagnetic field that Reichenbach presented in his note should (...) not be regarded as merely a virtuoso mathematical exercise, but as an additional argument supporting the core philosophical message of his 1928 monograph. This paper concludes by suggesting that Reichenbach’s infamous ‘relativization of geometry’ was only a stepping stone on the way to his main concern—the question of the ‘geometrization of gravitation’.

One of the persistent debates that has animated thinkers concerns the nature of consciousness. Is it merely an epiphenomenon that can be reduced to matter or does it belong to a different ontological domain? In recent times, this question has been reformulated as the hard problem of how material brain states can give rise to the mental states that we seem to experience. One of the answers to the hard problem has been to deflate the question and simply deny that (...) there is a problem. This chapter argues that this approach often associated with Dennett and embraced by Siderits is problematic within the framework of Buddhist philosophy given the latter’s strong insistence on observing how things appear to the mind. This essay further argues that Buddhism offers resources to deal with the hard problem through the Madhyamaka philosophy, which argues that it does not make sense to think how things are and that we should be content to deal with how things appear. In this perspective, the task of explaining consciousness is neither to eliminate appearances à la Dennett nor to discover what the mind really is in itself, but to learn how to correlate better the various appearances though which the mental is given (the first and third person perspectives). In this way, the hard problem ceases to be a mystery and becomes an object of scientific inquiry that relies on the ever tighter observation of the neuro-phenomenological correlation between first and third person perspectives.

This paper argues that the much discussed issue between "scientific realism" and "instrumentalism" has not been clearly drawn. Particular attention is paid to the claim that only realism can "explain" the success of scientific theories and---more especially---the progressively increasing success of such theories in a coherent line of inquiry. This claim is used to attempt to reach a clearer conception of the content of the realist thesis that underlies it; but, it is here contended, that attempt fails, and the claim (...) itself hangs in the air. A series of increasingly sophisticated versions of the "instrumentalist" thesis is considered, and both these and the contentions of realism are placed in relation both to particular examples of scientific development and positions historically maintained by philosophers and by scientists. The author’s conclusion is that, when the positions are assessed against the background of the actual history of science, each of the contrary doctrines, interpreted with excessive simplicity, is inadequate as a theory of the dialectic of scientific development; each, so interpreted, has contributed in important instances to actual damage to investigations by great scientists ; whereas in both the theoretical statements and the actual practice of the most sophisticated philosophers/scientists, important aspects of realism and instrumentalism are present together in such a way that the alleged contradiction between them vanishes.

In his 1916 review paper on general relativity, Einstein made the often-quoted oracular remark that all physical measurements amount to a determination of coincidences, like the coincidence of a pointer with a mark on a scale. This argument, which was meant to express the requirement of general covariance, immediately gained great resonance. Philosophers such as Schlick found that it expressed the novelty of general relativity, but the mathematician Kretschmann deemed it as trivial and valid in all spacetime theories. With the (...) relevant exception of the physicists of Leiden (Ehrenfest, Lorentz, de Sitter, and Nordström), who were in epistolary contact with Einstein, the motivations behind the point-coincidence remark were not fully understood. Only at the turn of the 1960s did Bergmann (Einstein’s former assistant in Princeton) start to use the term ‘coincidence’ in a way that was much closer to Einstein’s intentions. In the 1980s, Stachel, projecting Bergmann’s analysis onto his historical work on Einstein’s correspondence, was able to show that what he started to call ‘the point-coincidence argument’ was nothing but Einstein’s answer to the infamous ‘hole argument’. The latter has enjoyed enormous popularity in the following decades, reshaping the philosophical debate on spacetime theories. The point-coincidence argument did not receive comparable attention. By reconstructing the history of the argument and its reception, this paper argues that this disparity of treatment is not justified. This paper will also show that the notion that only coincidences are observable in physics marks every critical step of Einstein’s struggle with the meaning of coordinates in physics. (shrink)

While artificial intelligence (AI) is increasingly applied for decision-making processes, ethical decisions pose challenges for AI applications. Given that humans cannot always agree on the right thing to do, how would ethical decision-making by AI systems be perceived and how would responsibility be ascribed in human-AI collaboration? In this study, we investigate how the expert type (human vs. AI) and level of expert autonomy (adviser vs. decider) influence trust, perceived responsibility, and reliance. We find that participants consider humans to be (...) more morally trustworthy but less capable than their AI equivalent. This shows in participants’ reliance on AI: AI recommendations and decisions are accepted more often than the human expert’s. However, AI team experts are perceived to be less responsible than humans, while programmers and sellers of AI systems are deemed partially responsible instead. (shrink)

As is clear in the 2008 report of the President's Council on Bioethics, the brain death debate is plagued by ambiguity in the use of such key terms as ‘integration’ and ‘wholeness’. Addressing this problem, I offer a plausible ontological account of organismal unity drawing on the work of Hoffman and Rosenkrantz, and then apply that account to the case of brain death, concluding that a brain dead body lacks the unity proper to a human organism, and has therefore undergone (...) a substantial change. I also show how my view can explain hard cases better than one in which biological integration is taken to imply ontological wholeness or unity. (shrink)

Famously Ryle imagined a visitor who has seen the colleges, departments, and libraries of a university but still wonders where the university is. The visitor fails to realize that the university consists of these organizational units. In this paper I ask what exactly the relation is between institutional entities such as universities and the entities they are composed of. I argue that the relation is constitution, and that it can be illuminated in terms of constitutive rules. The understanding of the (...) ontology of institutions that constitutive rules provide, however, is incomplete. In order to capture the practical significance of institutions, I introduce the notion of a status rule. Status rules concern the normative powers of institutions. The status account of institutions defended here is used to solve the problem of freestanding status terms: it turns out to be rather difficult to identify the entities of which statuses such as corporations and electronic money are composed. Unable to solve this problem, Searle concludes that they are created out of thin air. I criticize this claim and argue that these statuses are imposed on persons. (shrink)

The essay critically engages Woltertorff’s account of justice by challenging the political status of its archaeological defence of rights language, its prioritizing of ‘primary’ and therefore ‘procedural’ justice, its suggestion to think of rights as ‘social bonds’ and the validity of subjecting God and world under one and the same concept of ‘worth’.

Recent research put forward the hypothesis that eye movements are integrated in memory representations and are reactivated when later recalled. However, “looking back to nothing” during recall might be a consequence of spatial memory retrieval. Here, we aimed at distinguishing between the effect of spatial and oculomotor information on perceptual memory. Participants’ task was to judge whether a morph looked rather like the first or second previously presented face. Crucially, faces and morphs were presented in a way that the morph (...) reactivated oculomotor and/or spatial information associated with one of the previously encoded faces. Perceptual face memory was largely influenced by these manipulations. We considered a simple computational model with an excellent match that expresses these biases as a linear combination of recency, saccade, and location. Surprisingly, saccades did not play a role. The results suggest that spatial and temporal rather than oculomotor information biases perceptual face memory. (shrink)

That truth provides the standard for believing appears to be a platitude, one which dovetails with the idea that in some sense belief aims only at the truth. In recent years, however, an increasing number of prominent philosophers have suggested that knowledge provides the standard for believing, and so that belief aims only at knowledge. In this paper, I examine the considerations which have been put forward in support of this suggestion, considerations relating to lottery beliefs, Moorean beliefs, the criticism (...) and defence of belief, and the value of knowledge. I argue that those considerations do not give us reason to give up the truth view in favour of the knowledge view and, moreover, that reflection on those considerations gives us some reason to reject the knowledge view. Thus, I conclude, we can continue to the take the apparent platitude at face value. (shrink)

Scholars have long debated whether welfare policymaking in industrialized democracies is responsive to citizen preferences and whether such policymaking is more responsive to rich than to poor citizens. Debate has been hampered, however, by difficulties in matching data on attitudes toward particular policies to data on changes in the generosity of actual policies. This article uses better, more targeted measures of policy change that allow more valid exploration of responsiveness for a significant range of democracies. It does so by linking (...) multicountry and multiwave survey data on attitudes toward health, pension, and unemployment policies and data on actual policy generosity, not just spending, in these domains. The analysis reveals that attitudes correlate strongly with subsequent changes in welfare generosity in the three policy areas and that such responsiveness is much stronger for richer than for poorer citizens. Representation is likely real but also vastly unequal in the welfare politics of industrialized democracies. (shrink)

This paper is concerned with some aspects of Kant’s transcendental idealism, in particular the claim that objects of experience are nothing but representations in us, and its connection to the distinction of things in themselves and appearances. This claim has prompted phenomenalist readings which have rightly been rejected almost unanimously. Instead it has been suggested to account for Kant’s distinction in terms of mind-dependent or subject-relativized properties and properties which are not mind-dependent or subject-relativized. Along this line, the “nothing but (...) representation”-claim is then sometimes understood in terms of the secondary-quality analogy, which Kant endorses in the Prolegomena, but rejects in the first Critique. As an alternative, I attempt to interpret Kant along the lines of Suárez’s formal/objective distinction and Scotus’s modal explication of being. (shrink)

To what level are invisible stimuli processed by the brain in the absence of conscious awareness? It is widely accepted that simple visual properties of invisible stimuli are processed; however, the existence of higher-level unconscious processing (e.g., involving semantic or executive functions) remains a matter of debate. Several methodological factors may underlie the discrepancies found in the literature, such as different levels of conservativeness in the definition of "unconscious" or different dependent measures of unconscious processing. In this research topic, we (...) are particularly interested in yet another factor: inherent differences in the amount of information let through by different suppression techniques. In the same conditions of well-controlled, conservatively established invisibility, can we show that some of the techniques in the "psychophysical magic" arsenal (e.g., masking, but also visual crowding, attentional blink, etc.) reliably lead to higher-level unconscious processing than others (e.g., interocular suppression)? Some authors have started investigating this question, using multiple techniques in similar settings. We argue that this approach should be extended and refined. Indeed, in order to delineate the frontiers of the unconscious mind using a contrastive method, one has to disentangle the limits attributable to unawareness itself, and those attributable to the technique inducing unawareness. The scope of this research topic is to provide a platform for scientists to contribute insights and further experiments addressing this fundamental question. (shrink)

Owned objects are typically viewed as non-fungible-they cannot be freely interchanged. We report three experiments (total N=312) demonstrating this intuition in preschool-aged children. In Experiment 1, children considered an agent who takes one of two identical objects and leaves the other for a peer. Children viewed this as acceptable when the agent took his own item, but not when he took his peer's item. In Experiment 2, children considered scenarios where one agent took property from another. Children said the victim (...) could take back her own property from the perpetrator, but that she could not take an identical object belonging to the perpetrator. Finally, in Experiment 3A and 3B, children considered scenarios where a teacher could give a child either of two objects to play with-an object that the child had recently played with, or another object that looked the same. Children were more likely to say that the teacher should give the object recently played with when it belonged to the child, compared with when it belonged to the teacher. These findings are informative about the basis of judgments that property is non-fungible, and about young children's representation of ownership rights. They show that children's representation of ownership rights is not limited to principles protecting owners from being deprived. Our findings instead suggest that ownership rights are viewed as pertaining to individual objects. (shrink)

Attention makes things look brighter and more colorful. In light of these effects, representationalist philosophers propose that attentive experiences represent more determinate color properties than inattentive experiences. Although this claim is appealing, we argue that it does not hold for one of our best conceptualizations of content determinacy, according to which an experience has more determinate contents if it represents a narrower range of values within the relevant dimension. We argue that our current empirical evidence fails to show that attention (...) has this kind of effect on color perception. We then offer an alternative, representationalist-friendly account of the attentional effects, as changes in vividness. (shrink)

The paper offers a historical overview of Einstein's oscillating attitude towards a "phenomenological" and "dynamical" treatment of rods and clocks in relativity theory. Contrary to what it has been usually claimed in recent literature, it is argued that this distinction should not be understood in the framework of opposition between principle and constructive theories. In particular Einstein does not seem to have plead for a "dynamical" explanation for the phenomenon rods contraction and clock dilation which was initially described only "kinematically". (...) On the contrary textual evidence shows that, according to Einstein, a realistic microscopic model of rods and clocks was needed to account for the very existence of measuring devices of "identical construction" which always measure the same unit of time and the same unit of length. In fact, it will be shown that the empirical meaningfulness of both relativity theories depends on what, following Max Born, one might call the "principle of the physical identity of the units of measure". In the attempt to justify the validity of such principle, Einstein was forced by different interlocutors, in particular Hermann Weyl and Wolfgang Pauli, to deal with the genuine epistemological, rather then physical question whether a theory should be able or not to described the material devices that serve to its own verification.

This paper answers two questions. First, on the assumption that risk of harm is of moral significance, does risk’s moral significance lay in its being harmful? Second, is risk of harm itself harmful? I argue that either risk is not harmful or that risk is harmful only in a small range of cases. If risk is not harmful, and yet risk is of moral significance, risk’s moral significance cannot lie in its being harmful. And if risk is harmful only in (...) a small range of the cases in which risk is of moral significance, risk’s moral significance cannot lie in its being harmful. (shrink)

A curious feature of Belnap’s “useful four-valued logic”, also known as first-degree entailment (FDE), is that the overdetermined value B (both true and false) is treated as a designated value. Although there are good theoretical reasons for this, it seems prima facie more plausible to have only one of the four values designated, namely T (exactly true). This paper follows this route and investigates the resulting logic, which we call Exactly True Logic.
