The access problem for mathematics arises from the supposition that the referents of mathematical terms inhabit a realm separate from us. Quine’s approach in the philosophy of mathematics dissolves the access problem, though his solution sometimes goes unrecognized, even by those who rely on his framework. This paper highlights both Quine’s position and its neglect. I argue that Michael Resnik’s structuralist, for example, has no access problem for the so-called mathematical objects he posits, despite (...) recent criticism, since he relies on an indispensability argument. Still, Resnik’s structuralist does not provide an account of our access to traditional mathematical objects, and this may be seen as a problem. (shrink)

I argue that recent attempts to deflect Access Problems for realism about a priori domains such as mathematics, logic, morality, and modality using arguments from evolution result in two kinds of explanatory overkill: the Access Problem is eliminated for contentious domains, and realist belief becomes viciously immune to arguments from dispensability, and to non-rebutting counter-arguments more generally.

Epistemological disjunctivism, as defended by, for example, McDowell, Neta and Pritchard, is the view that epistemic justification can be – and in paradigmatic cases of perceptual knowledge actually is – both factive and reflectively accessible. One major problem for this view is the access problem: apparently, epistemological disjunctivism entails that ordinary external world propositions can be known by reflection alone. According to epistemological disjunctivism, seeing that the sun is shining is reflectively accessible and seeing that the sun (...) is shining entails that it is. Assuming closure of reflective knowledge under known entailment it is also reflectively knowable that the sun is shining. Drawing on joint work with Neta, Pritchard replies that disjunctivism is not committed to this absurdity, but only to the possibility of reflective access to empirical reasons. In this article I offer an interpretation of this reply, but also an objection to it: my interpretation is based on applying the source/content distinction to epistemic reasons. My objection is based on arguing that the access problem is a problem for any version of access internalism. Although Pritchard's reply solves the general access problem, it does not solve the access problem that is generated by the specific commitments of epistemological disjunctivism. Due to the transparency of self-knowledge of propositional perception, epistemological disjunctivism cannot meet a central requirement for applying the source/content distinction. (shrink)

A range of current truth-value realist philosophies of mathematics allow one to reduce the Benacerraf Problem to a problem concerning mathematicians' ability to recognize which conceptions of pure mathematical structures are coherent – in a sense which can be cashed out in terms of logical possibility. In this paper I will clarify what it takes to solve this `residual' access problem and then present a framework for solving it.

In this article, I discuss a trivialization worry for Hartry Field’s official formulation of the access problem for mathematical realists, which was pointed out by Øystein Linnebo (and has recently been made much of by Justin Clarke-Doane). I argue that various attempted reformulations of the Benacerraf problem fail to block trivialization, but that access worriers can better defend themselves by sticking closer to Hartry Field’s initial informal characterization of the access problem in terms of (...) (something like) general epistemic norms of coincidence avoidance. (shrink)

Ante rem structuralism is the doctnne that mathematics descubes a realm of abstract (structural) universab. According to its proponents, appeal to the exutence of these universab provides a source distinctive insight into the epistemology of mathematics, in particular insight into the so-called 'access problem' of explaining how mathematicians can reliably access truths about an abstract realm to which they cannot travel andfiom which they recave no signab. Stewart Shapiro offers the most developed version of this view to (...) date. Through an examination of Shapiro's proposed structuralist epistemology for mathematics I argue that ante rem structuralism faib to provide the ingredients for a satisfactory resolution of the access problem for infinite structures (whether small or large).

The Access principle places an epistemic restriction on our obligations. This principle falls prey to the ‘Shirker Problem’, namely that shirkers could evade their obligations by evading certain epistemic circumstances. To block this problem, it has been suggested that shirkers have the obligation to learn their obligations. This solution yields a regress, yet it is controversial what the moral of the regress actually is. The aim of this paper is two-fold. First, I spell out this intricate dispute. (...) Second, on the basis of my analyses I propose solutions to the Shirker Problem. (shrink)

In opposition to mainstream theory of mind approaches, some contemporary perceptual accounts of social cognition do not consider the central question of social cognition to be the problem of access to other minds. These perceptual accounts draw heavily on phenomenological philosophy and propose that others' mental states are “directly” given in the perception of the others' expressive behavior. Furthermore, these accounts contend that phenomenological insights into the nature of social perception lead to the dissolution of the access (...) problem. We argue, on the contrary, that the access problem is a genuine problem that must be addressed by any account of social cognition, perceptual or non-perceptual, because we cannot cast the access problem as a false problem without violating certain fundamental intuitions about other minds. We elaborate the fundamental intuitions as three constraints on any theory of social perception: the Immediacy constraint; the Transcendence constraint; and the Accessibility constraint. We conclude with an outline of an account of perceiving other minds that meets the three constraints. (shrink)

I argue that the two-dimensional hyperintensions of epistemic topic-sensitive two-dimensional truthmaker semantics provide a compelling solution to the access problem. -/- I countenance an abstraction principle for two-dimensional hyperintensions based on Voevodsky's Univalence Axiom and function type equivalence in Homotopy Type Theory. The truth of my first-order abstraction principle for two-dimensional hyperintensions is grounded in its being possibly recursively enumerable i.e. Turing computable and the Turing machine being physically implementable. I apply, further, modal rationalism in modal epistemology to (...) solve the access problem. Epistemic possibility and hyperintensionality, i.e. conceivability, can be a guide to metaphysical possibility and hyperintensionality, when (i) epistemic worlds or epistemic hyperintensional states are interpreted as being centered metaphysical worlds or hyperintensional states, i.e. indexed to an agent, when (ii) the epistemic (hyper-)intensions and metaphysical (hyper-)intensions for a sentence coincide, i.e. the hyperintension has the same value irrespective of whether the worlds in the argument of the functions are considered as epistemic or metaphysical, and when (iii) sentences are said to consist in super-rigid expressions, i.e. rigid expressions in all epistemic worlds or states and in all metaphysical worlds or states. I argue that (i) and (ii) obtain in the case of the access problem. (shrink)

This essay denaturalizes the taken-for-granted meaning of ‘access’ and interrogates its role and lived meaning in ableist social worlds, with a focus on spaces of higher education. I suggest that legalistic approaches to access need ‘cripping’ by a disability framework. Currently, these approaches (1) miss the intersubjective sociality of being-in-the-world; (2) they prioritize a narrow conception of access focused on ‘physical’ access and ‘physical’ space (a typology I contest); (3) they approach access as frozen in (...) time, rather than as a relational and temporally dynamic process (4); and, finally, they contribute to bureaucratizing and privatizing disability knowledge. I examine ‘access’ through the lens of belonging by asking how we orient ourselves in spaces shaped by oppressive social norms. I argue that ableist lifeworlds generate serious disorientations for disabled people that are lasting, structurally enforced, and harmful or debilitating. (shrink)

The purpose of the study is to develop proposals for the liberalization of the financial services sector of the economy of Turkmenistan in the context of the country's potential accession to the World Trade Organization. The article considers the problems and challenges that Turkmenistan may face in the process of negotiations on the terms of accession to the WTO. The scientific novelty lies in the theoretical justification of the expediency of maintaining the status quo in trade in financial services in (...) the short and medium term within the initial list of specific obligations of the country provided for by the GATS. As a result, in the conditions of macroeconomy and its transitional nature, taking into account the unpredictable volatility of hydrocarbon prices, it is recommended to leave the existing restrictions on access to the financial services market and on the national regime unchanged in the context of a gradual process of lifting restrictions on the movement of capital and its complete liberalization.

A successful proposal to reform the existing system must address these challenges of access and innovation. This essay will survey the problems in the existing pharmaceutical patent system and offer (...) critical analysis of some reform proposals. I will argue that existing mechanisms that are intended to mitigate the harms of the current pharmaceutical patent system, such as bulk buying, differential pricing and compulsory licenses, are inadequate and perhaps even counter-productive over the long-term. Other incentive mechanisms based on push funding, such as government research grants, are inefficient and limited in scope. Pull mechanisms, which offer some reward for successful pharmaceutical innovations, offer a more promising incentive mechanism. I will evaluate three pull mechanisms -- Priority Review Vouchers, Advance Market Commitment (AMC) and the Health Impact Fund -- on the basis of their capacity to incentivize access and innovation, as well as their efficiency and political feasibility. Though the Health Impact Fund appears to be the most promising proposal, more work must be done to overcome challenges of its implementation. CiteULike Connotea Del.icio.us What's this? (shrink)

The problem of the right access and the formal indication. The phenomenological hermeneutics of facticity, Heidegger’s first philosophical program, cannot be understood from the usual idea that opposes hermeneutical ontology to the primacy of method; On the contrary, its fundamental problem is that of the “right access” to factical life. The importance of this problem contains a mutual implication between the subject (factical life) and the method. It is concerned with the determination of the original (...) Gegebenheit of factical life and with the modes of its apprehension. This paper aims at explaining the status and function of the specific phenomenological means required by this problem. (shrink)

This article argues that effective corporate social responsibility (CSR) of multinational pharmaceutical companies in developing countries should reflect context, opportunity, proximity, time and impact in accordance with the social integration and ethical approaches to CSR. It proposes a CSR model expressed as CSR=COPTI+SI+E, which acknowledges access-to-medicines as a matter in the global public domain, a public choice problem and a moral responsibility issue for multinational pharmaceutical companies. This model recognises the globalisation of the principle of humanity in communities (...) of place and communities of interest as highlighted by the Global Economic Ethic Manifesto 2009 as an integral part of the responsibilities of multinational pharmaceutical companies. The model reflects a global application of the concept of disadvantaged consumer already known to some national laws. The article suggests an access-to-medicines CSR framework for pharmaceutical companies which may include pricing, patents, testing and clinical trials, research and development, joint public private initiative and appropriate use of drugs.

In this paper, I consider the so-called Access Problem for Duncan Pritchard’s Epistemological Disjunctivism (2012). After reconstructing Pritchard’s own response to the Access Problem, I argue that in order to assess whether Pritchard’s response is a satisfying one, we first need an account of the notion of ‘Reflective Access’ that underpins Pritchard’s Epistemological Disjunctivism. I provide three interpretations of the notion of Reflective Access: a metaphysical interpretation, a folk interpretation, and an epistemic interpretation. I (...) argue that none of these three interpretations comes without problems. I conclude that, until we have a clear and unproblematic account of Reflective Access, the Access Problem remains a challenge for Pritchard’s Epistemological Disjunctivism. (shrink)

This article, which analyses relevant cases that have already been the subject of academic commentary, examines some of the most commonly recurring problems in the proper ascertainment of foreign law.

The easy problems of consciousness are those that seem directly susceptible to the standard methods of cognitive science, whereby a phenomenon is explained in terms of computational or neural mechanisms. The hard problems are those that seem to resist those methods. The easy problems are easy precisely because they concern the explanation of cognitive abilities and functions. Once we have specified the neural or computational mechanism that performs the function of verbal report, for example, the bulk of our work in (...) explaining reportability is over. Baars theory of cognitive accessibility addresses many aspects of human cognition and shows promise as a theory of awareness, the functional correlate of conscious experience, but an explanation of experience itself is not on offer. The key is the conceptual point that the explanation of functions does not suffice for the explanation of experience. (shrink)

How can we acquire a grasp of cardinal numbers, even the first very small positive cardinal numbers, given that they are abstract mathematical entities? That problem of cognitive access is the main focus of this paper. All the major rival views about the nature and existence of cardinal numbers face difficulties; and the view most consonant with our normal thought and talk about numbers, the view that cardinal numbers are sizes of sets, runs into the cognitive access (...) problem. The source of the problem is the plausible assumption that cognitive access to something requires causal contact with it. It is argued that this assumption is in fact wrong, and that in this and similar cases we should accept that a certain recognise-and-distinguish capacity is sufficient for cognitive access. We can then go on to solve the cognitive access problem, and thereby support the set-size view of cardinal numbers, by paying attention to empirical findings about basic number abilities. To this end some selected studies of infants, pre-school children and a trained chimpanzee are briefly discussed. (shrink)

Deep beneath the surface of Kant's theory of knowledge lies the metaphysical doctrine of noumena, things in themselves, intelligible entities . For lengthy periods these creatures are surprisingly unobtrusive and can be safely disregarded. But at certain points Kant hauls them to the surface and tries to put them to work in perplexing ways. My concern is not with these attempts, but with what can be learned, if not salvaged, from the metaphysical doctrine as it is expounded in the chapter (...) in the Critique of Pure Reason entitled ‘The Ground of the Distinction of all Objects in General into Phenomena and Noumena’. I shall start by giving, for the most part in Kant's own words, as blunt an account as possible of how he appears to reduce his own doctrine to nonsense. I shall then argue that such an account, while not straightforwardly wrong, ignores matters of very great interest. I shall do so in terms of two theories, which I distinguish, about the relationship between knowing, changing and conceptualizing. Finally, I shall draw some more and less general conclusions.

The Mass Density approach to GRW (GRWm for short) has been widely discussed in the quantum foundations literature. A crucial feature of GRWm is the introduction of a Criterion of Accessibility for mass, which allows to explain the determinacy of experimental outcomes thus also addressing the tails problem of GRW. However, the Criterion of Accessibility leaves the ontological meaning of the non-accessible portion of mass utterly unexplained. In this paper I discuss two viable approaches to non-accessible mass, which I (...) call anti-realist and realist, and will defend the latter. First, I show that the anti-realist approach suffers from various objections. Second, I develop an account of non-accessible mass density states as objectively indeterminate states of affairs.

The paper attempts to show that Predictive Processing (PP), despite recent attempts by its proponents to ward off accusations that lead to skepticism (Clark, A. (2016). _Surfing uncertainty: prediction, action and the embodied mind_. Oxford University Press, Clark, A. (2019). Replies to critics: In search of the embodied, extended, enactive predictive (EEE-P) mind. In M. Colombo, E. Irvine, & M. Stapleton (Eds.), _Andy Clark and his critics_ (pp. 266–302). Oxford University Press), is susceptible to undesirable skeptical consequences of a Kantian (...) (rather than Cartesian) character. Specifically, I shall argue that Clark’s version of PP is susceptible to a particularly Kantian version of skepticism in which the external world directly revealed by PP generative models is a _phenomenal_ one in the Kantian sense: A world perceived and conceived _as_ external, but at the same time essentially ‘internal’ in its categorial form, where this ‘internality’ only diverges from Kant in that it is a consequence of evolution. It will be suggested that these skeptical consequences can be avoided by articulating a more nuanced notion of the boundary between mind and world in PP, namely, one that differentiates an _ontological_ from an _epistemological_ understanding of the boundary between mind (generative model) and world. Moreover, it will be argued that in order to avoid Kantian skepticism, we must construe the very distinction between the phenomenal world and the world as it is in itself in non-metaphysical, pragmatic terms, as a framework condition for epistemically coordinating empirical inquiry within an ever-changing and unpredictable world. As a bonus, this view seems capable of accommodating the insights of autopoietic enactivism without buying into the latter’s controversial ‘transcendental idealist’ organism-relative ontology.

In this paper, I focus on the Armchair Access Problem for E=K as presented by Nicholas Silins (2005), and I argue, contra Silins, that it does not represent a real threat to E=K. More precisely, I put forward two lines of response, both of which put pressure on the main assumption of the argument, namely, the Armchair Access thesis. The first line of response focuses on its scope, while the second line of response focuses on its nature. (...) The second line of response is the most interesting one, for it represents the framework within which I develop a novel account of second-order knowledge, one that involves evaluation of counterfactual conditionals and the employment of our imaginative capacities, i.e., an imagination-based account of second-order knowledge. The two lines of response are shown to be jointly compatible and mutually supportive. I then conclude that the Armchair Access Problem is not a challenge for E=K, yet it relies on the ambiguity of the notion of armchair knowledge underpinning the Armchair Access thesis. (shrink)

Epistemological disjunctivists such as Duncan Pritchard claim that in paradigmatic cases of knowledge the rational support for the known propositions is both factive and reflectively accessible. This position faces some problems, including the basis problem – how can our knowledge be based on such strong reasons that seem to leave no room for non-knowledge and therefore presuppose knowledge? – and the access problem – can disjunctivists avoid the implausible claim that we can achieve knowledge through inference from (...) our introspective awareness of those reasons? I argue that disjunctivists cannot solve both of these problems at the same time by posing the dilemma question whether we can have factive and reflectively accessible reasons without knowledge. While I focus on Pritchard throughout most of the paper, I argue in the last section that other anti-skeptical versions of disjunctivism face the same dilemma. (shrink)

Jay Rosenberg introduces Immanuel Kant's masterwork, the Critique of Pure Reason, from a "relaxed" problem-oriented perspective which treats Kant as an especially insightful practicing philosopher, from whom we still have much to learn, intelligently and creatively responding to significant questions that transcend his work's historical setting. Rosenberg's main project is to command a clear view of how Kant understands various perennial problems, how he attempts to resolve them, and to what extent he succeeds. At the same time the book (...) is an introduction to the challenges of reading the text of Kant's work and, to that end, selectively adopts a more rigorous historical and exegetical stance. Accessing Kant will be an invaluable resource for advanced students and for any scholar seeking Rosenberg's own distinctive insights into Kant's work. (shrink)

Analyzing the problems of decision making in the preceding chapter, the question posed here is “why would someone challenge grounds on which someone else makes political decisions?” Various answers are provided: intrinsic inadequacy, unfairness and danger to social harmony, stability, or progress. On the other hand, the chapter asks: what are the grounds that may be appropriately relied upon for political decisions? The chapter proposes realist, shared social and authority grounds. Realism asserts that moral claims are subject to predicates of (...) truth and falsity, that they are objectively correct or incorrect. The chapter also argues that making political judgments on grounds that are commonly shared is often appropriate, even if these grounds extend beyond what can be justified directly on accessible realist bases. Finally, the ground of authority is discussed based on three scenarios: straightforward application, discretion, and interpretation. (shrink)

Internet based process control usage has grown in the past years. Industry field demands were behind this, and it ranges from factory, office and home automation to tasks simplifications and cost reduction. In this book a hardware interface circuit and a software system used to control the temperature and level of a liquid tank is described. The advantage of the designed interface circuit is its simplicity and low cost. The same can be true for the software system in which we (...) used C and Java programs to accomplish the communication. Both C and Java can be obtained freely and the development cost could be small. C language has been used to communicate with the designed interface circuit due to its strength in low level operations and communication with ports and hardware. In Java we have used mainly the Servlet for communication between the Client and the Server, which is a new approach and more reliable approach than the CGI based method that has common problems of speed and data persistence. This book is useful for people and researchers working in the field of control, remote access and computer based control. (shrink)

The development of access rights as, perhaps, a replacement for copyright in digital rights management (DRM) systems, draws our attention to the importance of ‚the balance problem’ between information industries and the individual user. The nature of just what this ‚balance’ is, is often mentioned in copyright writings and judgments, but is rarely discussed. In this paper I focus upon elucidating the idea of balance in intellectual property and propose that the balance concept is not only the most (...) feasible way to examine whether past solutions to copyright problems are fair, but it also provides the ability to predict what will be the better solution for all affected parties. Based upon an envy-free contribution towards predicting the efficient balance, game theory is applied in a novel manner to the DRM problem to infer where and what might be the optimal balance in the debate over the nature of access right.

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to (...) doubt their authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

The access-to-justice movement broadly concerns the extent to which people have the ability to resolve legally actionable problems. To the extent that individuals seek resolution through civil litigation, they can be disadvantaged by their unmet need for legal services, particularly in high-stakes cases and complicated areas of law. I propose an innovative legal intervention to this problem called “compensatory preliminary damages,” which builds from the work of Gideon Parchomovsky and Alex Stein. I argue that preliminary damages should function (...) as compensatory awards for harm to a plaintiff’s ability to access justice, rather than a contingency loan that might make indigent plaintiffs worse off than before if they lose. By awarding such damages, courts make plaintiffs whole for harm to their access to justice that is not conditional on a decision after the merits or their final recovery for the injuries alleged. As such, the award would not need to be repaid. -/- . (shrink)

In the Preface to his impressive and engaging new commentary on the Critique of Pure Reason, Jay Rosenberg informs us that the book is both a product of his own lectures and a “direct descendent of Wilfrid Sellars’ legendary introduction to Kant” . Its origins in the classroom give Accessing Kant a refreshingly pedagogical tone. Throughout, Rosen-berg—who was a student of Sellars’ at the University of Pittsburgh—makes felicitous use of clear examples, familiar problems and authors, and visual aids to clarify (...) “the Big Picture” operating in the first Critique. Mercifully, however, his style owes little to Sellars’ own brutally opaque prose.Rosenberg also shares his teacher’s enthusiasm for the history of philosophy. The reader will not find Rosenberg sloughing off Kant’s “lesser predecessors” in the manner of P. F. Strawson. However, the history on display in Accessing Kant has more to do with the curricular demands of English-speaking philosophy departments than with Kant’s own intellectual and cultural context. This means that his Kant argues across the ages with giants rather than with his peers in Halle and Berlin. Nor, despite the occasional reference to Kant’s handwritten marginalia, does Rosenberg devote any effort to. (shrink)

Basically agreeing with Block regarding the need for a distinction between P- and A-consciousness, I characterize the problem somewhat diflerently, relating it more directly to the explanatory gap. I also speculate on the relation between the two forms of consciousness, arguing that some notion of access is essentially involved in phenomenal experience.

Scientists engaged in global health research are increasingly faced with barriers to access and use of human tissues from the developing world communities where much of their research is targeted. In part, the problem can be traced to distrust of researchers from affluent countries, given the history of 'scientific-imperialism' and 'biocolonialism' reflected in past well publicized cases of exploitation of research participants from low to middle income countries. To a considerable extent, the failure to adequately engage host communities, (...) the opacity of informed consent, and the lack of fair benefit-sharing have played a significant role in eroding trust. These ethical considerations are central to biomedical research in low to middle income countries and failure to attend to them can inadvertently contribute to exploitation and erode trust. A 'tissue trust' may be a plausible means for enabling access to human tissues for research in a manner that is responsive to the ethical challenges considered. Preventing exploitation and restoring trust while simultaneously promoting global health research calls for innovative approaches to human tissues research. A tissue trust can reduce the risk of exploitation and promote host capacity as a key benefit. (shrink)

Sense-perception—the awareness or apprehension of things by sight, hearing, touch, smell and taste—has long been a preoccupation of philosophers. One pervasive and traditional problem, sometimes called “the problem of perception”, is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? The present entry is about how these possibilities of error challenge the intelligibility of (...) the phenomenon of perception, and how the major theories of perception in the last century are best understood as responses to this challenge.

Since the adoption of the WTO-TRIPS Agreement in 1994, there has been significant controversy over the impact of pharmaceutical patent protection on the access to medicines in the developing world. In addition to the market exclusivity provided by patents, the pharmaceutical industry has also sought to further extend their monopolies by advocating the need for additional ‘regulatory’ protection for new medicines, known as data exclusivity. Data exclusivity limits the use of clinical trial data that need to be submitted to (...) the regulatory authorities before a new drug can enter the market. For a specified period, generic competitors cannot apply for regulatory approval for equivalent drugs relying on the originator's data. As a consequence, data exclusivity lengthens the monopoly for the original drug, impairing the availability of generic drugs. This article illustrates how the pharmaceutical industry has convinced the US and the EU to impose data exclusivity on their trade partners, many of them developing countries. The key arguments formulated by the pharmaceutical industry in favor of adopting data exclusivity and their underlying ethical assumptions are described in this article, analyzed, and found to be unconvincing. Contrary to industry's arguments, it is unlikely that data exclusivity will promote innovation, especially in developing countries. Moreover, the industry's appeal to a property rights claim over clinical test data and the idea that data exclusivity can prevent the generic competitors from ‘free-riding’ encounters some important problems: Neither legitimize excluding all others.
