There have long been calls from industry for guidance in implementing strategies for sustainable development. The Circular Economy represents the most recent attempt to conceptualize the integration of economic activity and environmental wellbeing in a sustainable way. This set of ideas has been adopted by China as the basis of their economic development, escalating the concept in minds of western policymakers and NGOs. This paper traces the conceptualisations and origins of the Circular Economy, tracing its meanings, and exploring its antecedents (...) in economics and ecology, and discusses how the Circular Economy has been operationalized in business and policy. The paper finds that while the Circular Economy places emphasis on the redesign of processes and cycling of materials, which may contribute to more sustainable business models, it also encapsulates tensions and limitations. These include an absence of the social dimension inherent in sustainable development that limits its ethical dimensions, and some unintended consequences. This leads us to propose a revised definition of the Circular Economy as “an economic model wherein planning, resourcing, procurement, production and reprocessing are designed and managed, as both process and output, to maximize ecosystem functioning and human well-being”.

From an embodied and enactive point of view, the mind–body problem has been reformulated as the relation between the lived or subject body on the one hand and the physiological or object body on the other (“body–body problem”). The aim of the paper is to explore the concept of circularity as a means of explaining the relation between the phenomenology of lived experience and the dynamics of organism–environment interactions. This concept of circularity also seems suitable for connecting enactive (...) accounts with ecological psychology. It will be developed in a threefold way: (1) As the circular structure of embodiment, which manifests itself (a) in the homeostatic cycles between the brain and body and (b) in the sensorimotor cycles between the brain, body, and environment. This includes the interdependence of an organism’s dispositions of sense-making and the affordances of the environment. (2) As the circular causality, which characterizes the relation between parts and whole within the living organism as well as within the organism–environment system. (3) As the circularity of process and structure in development and learning. Here, it will be argued that subjective experience constitutes a process of sense-making that implies (neuro-)physiological processes so as to form modified neuronal structures, which in turn enable altered future interactions. On this basis, embodied experience may ultimately be conceived as the integration of brain–body and body–environment interactions, which has a top-down, formative, or ordering effect on physiological processes. This will serve as an approach to a solution of the body–body problem. (shrink)

Research on epistemic circularity has focused more on the problem of whether circular arguments are able to justify their conclusions rather than on the nature of circularity itself, and has kept a sharp delimitation from other types of circularities (logical, linguistic, and of definition). In this paper, I aim to move the focus toward the general concept of circularity, which I relate to the concept of ‘epistemic worry’. Through a brief overview on the known types of circularities, (...) I show that circularity has multiple natures (not only that associated with its type), and the linguistic aspect is essential in qualifying a construct as circular, which in turn raises the problem of genuineness of a circularity. Within an extensional approach, I suggest generalizing the meaning of the key epistemological terms referred to in the classical definition of epistemic circularity to also cover additional associated concepts specific to other theoretical disciplines beyond epistemology. The proposed concepts and ideas are reflected in a structural unificatory account of circularity in terms of epistemic determination, which raises a challenge to the relational accounts of determination in regard to the transitivity of the determination relation.

Is perception cognitively penetrable, and what are the epistemological consequences if it is? I address the latter of these two questions, partly by reference to recent work by Athanassios Raftopoulos and Susanna Seigel. Against the usual, circularity, readings of cognitive penetrability, I argue that cognitive penetration can be epistemically virtuous, when---and only when---it increases the reliability of perception.

This paper criticizes the circularity reading of Frege's argument for the indefinability of truth. According to this reading, Frege is appealing to a sort of circularity in the argument. I argue that the circularity reading is interpretatively incorrect, or makes Frege's argument a non‐starter.

The aim of this paper is to provide a model that allows the representation and analysis of circularity in ethotic structures, i.e. in communication structures related to the speaker’s character and in particular, his credibility. The paper studies three types of cycles: in self-referential sentences, embedded testimony and ethotic begging the question. It is shown that standard models allow the reconstruction of the circularities only if those circular utterances are interpreted as ethotic arguments. Their alternative, assertive interpretation requires enriching (...) the existing models with a purely ethotic component related to the credibility of the performer of any (not necessarily argumentative) speech act.

Context: Referring to a recent proposition by Kauffman about the “fundamental nature of circularity in cybernetics and in scientific work in general,” I try to advance this insight with the help of system scientific concepts and a computational model. Problem: Often circularity seems to be taken as a metaphor that does not provide a firm epistemological base that fosters analysis. Method: The methodology builds on mathematics, computer-based modeling, and reasoning. Results: By building on conceptual suggestions for grasping the (...) micro-macro difference of complex systems in terms of computational power, circularity can be conceived of as an emerging macro-level phenomenon. Implications: I show that the seemingly irritating - and traditionally evaded - concept of circularity is a fundamental and ubiquitous phenomenon in complex systems that can be grasped on a firm physical basis open to computational analysis. The proposal could support constructivist reasoning and help to eventually bridge the disconcerting gap between the humanities and natural sciences. Constructivist content: Circularity is a fundamental principle in the conception of second-order cybernetics and in particular in the observation of observing systems, as suggested by von Foerster. Trying to set it up on a firm analytical basis could advance the constructivist approach and further support it in becoming the contemporary scientific epistemology it deserves to be. (shrink)

This paper discusses some of the ways in which circular definitions and circular explanations entail or fail to entail infinite regresses. And since not all infinite regresses are vicious, a few criteria of viciousness are examined in order to determine when the entailment of a regress refutes a circular definition or a circular explanation.

Sosa's work on epistemic circularity has significance beyond his own brand of virtue epistemology, with its characteristic distinction between animal and reflective knowledge. On the contrary, it demonstrates the necessity of embracing foundationalism and externalism in epistemology, while at the same time answering various charges (some perennial) against epistemology in general. This paper distinguishes six kinds of epistemic circularity that are discussed in Sosa's work: two virtuous, two vicious, and two benign. This framework is used to reconstruct Sosa's (...) responses to various problems involving charges of epistemic circularity. In particular, we look at Sosa's response to e Problem of the Criterion.

The Fourth Industrial Revolution based on digitalization, the development of AI, robotics, big data, and increasing automation is dredging up older debates on the end of human work. This article contributes to this debate arguing that these changing circumstances represent an opportunity to advance a renewed consideration of human work. By emphasizing its most distinctively human dimensions, including gratuitousness, relationality, and meaningfulness, we propose the articulation of a social model that recognizes relational goods as a specific contribution of human work (...) in an attempt to overcome the state and the market's monopoly of public life built around the dichotomy between the private and the public. Such a social model is based on the concept of circular subsidiarity, which represents a departure from traditional notions of subsidiarity by promoting a dynamic and reciprocal interplay between three essential societal spheres: the state, the market, and organized civil society, all of which have their role to fulfill by providing security, efficiency, and relational goods. Ultimately, this article suggests that circular subsidiarity can lead to a more inclusive and equitable social model by acknowledging how relational goods not only humanize civil society but also sustain the functioning of both the market and the state.

Epistemically circular arguments have been receiving quite a bit of attention in the literature for the past decade or so. Often the goal is to determine whether reliabilists (or other foundationalists) are committed to the legitimacy of epistemically circular arguments. It is often assumed that epistemic circularity is objectionable, though sometimes reliabilists accept that their position entails the legitimacy of some epistemically circular arguments, and then go on to affirm that such arguments really are good ones. My goal in (...) this paper is to argue against the legitimacy of epistemically circular arguments. My strategy is to give a direct argument against the legitimacy of epistemically circular arguments, which rests on a principle of basis-relative safety, and then to argue that reliabilists do not have the resources to resist the argument. I argue that even if the premises of an epistemically circular argument enjoy reliabilist justification, the argument does not transmit that justification to its conclusion. The main goal of my argument is to show that epistemic circularity is always a bad thing, but it also has the positive consequence that reliabilists are freed from an awkward commitment to the legitimacy of some intuitively bad arguments.

Circular sets are said to provide clear-cut cases of circular orders of ontological dependence. I argue that this claim is unwarranted given the epistemic parity of two principles of set-dependence.

Disagreement and debunking arguments threaten religious belief. In this paper, I draw attention to two types of propositions and show how they reveal new ways to respond to debunking arguments and disagreement. The first type of proposition is the epistemically self-promoting proposition, which, when justifiedly believed, gives one a reason to think that one reliably believes it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield an epistemically circular argument in response to (...) certain debunking arguments. The second type of proposition is the epistemically others-demoting proposition, which, when justifiedly believed, gives one a reason to think that others are unreliable with respect to it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield a question-begging argument to respond to certain types of disagreement. (shrink)

Sometimes we get what seem to be good reasons for believing that we’ve misevaluated our evidence for a proposition P. In those cases, can we use our evidence for P itself to show that we haven’t misevaluated our evidence for P? I show why doing so appears to employ viciously circular reasoning. However, I then argue that this appearance is illusory in certain cases and that we sometimes can legitimately reason in that way. This claim sheds new light on the (...) nature of epistemic undermining and epistemic circularity. In addition, it has implications for the current debate about the epistemic significance of disagreement. An important and influential position in that debate says that disagreement with others dramatically undermines our justification for a wide range of our opinions (e.g., political, religious, moral, economic, and philosophical opinions). My view on undermining and circularity implies that this position on disagreement rests on a mistake. (shrink)

The present article examines two important challenges raised by Steup for explanationist accounts of evidential fit. The first challenge targets the notion of available explanation which is key to any explanationist account of evidential fit. According to Steup, any plausible construal of the notion of available explanation already presupposes the notion of evidential fit. In response to that challenge, an alternative conception of what it takes for an explanation to be available to a subject is offered and shown to be (...) able to shed better light on the specific role played by that notion in explanationist accounts of evidential fit. The second challenge relies on the claim that the explanatory goodness of competing explanations is determined by their evidential fit, rather than the other way around. In response to that challenge, it is argued that explanationists can concede that the relative explanatory goodness of an explanation is in part dependent on that explanation’s likeliness on the overall evidence possessed by the subject without thereby conceding that Explanationism about justification is circular.

This study represents an empirical, comprehensive investigation of two different inter-organisational collaborative approaches, offering a novel perspective on collaborative circular business models in the modern economy. In this vein, we explore how open innovation strategies foster the implementation of circular economy practices within a circular supply chain and a circular ecosystem. In addition, we identify and characterise stakeholders' roles in facilitating the translation of circular principles into a viable business. An inductive theorising approach was employed, leveraging an explorative multiple case (...) study methodology. Data were collected from 13 organisations involved in two collaborative networks, designed to establish upcycling practices to recover waste from the food and beverage industry. A critical realist philosophical positioning underpinned researchers' data collection and analysis. As a result, we outline the nature of two different collaborative approaches to pursue a regenerative production system through open innovation strategies: a circular supply chain and a circular ecosystem architecture. The characterisation of the coordinator and orchestrator of collaborative circular business models is also highlighted in our findings. In sum, this study contributes to the literature on circular economy by unveiling the role of open innovation in fostering circular business development. From a practical standpoint, it offers insights for managers of sustainability-oriented companies willing to implement upcycling practices. (shrink)

Circular economy thinking has become the subject of academic enquiry across several disciplines recently. Yet whilst its technical and business angles are more widely discussed, its philosophical underpinnings and socio-economic implications are insufficiently investigated. In this article, we aim to contribute to their understanding by uncovering the circular economy role in shaping a new vision, highlighting the social and economic dimensions of future imaginaries and the mechanisms that can enable them to bring about change in the social context. We believe (...) that defining the vision that the circular economy is contributing to shape is key to explain its conceptual framework and activities. Drawing on the concept of fictional expectations, we uncover one of the plausible social dimensions inherent to the circular economy thinking thereby opening up a new perspective on the current debate in the circular economy literature wherein authors, by contrast, are emphasising the lack of an explicit social dimension. Fictional expectations are introduced to refer to those imaginaries of the future that can catalyse social action in the present and counteract societal addictions, in which modern society seems to be trapped. We show how a circular economy inspired vision can be instrumental to the emergence of a fictional expectation that can provide therapies to the current societal addiction of wasteful production and consumption systems. This philosophical background allows us to provide, in conclusion, a new conceptualisation of the circular economy as a cognitive framework instrumental to the emergence of a future imaginary.

The International System of Units tries to find or construct something that does not change with time and place, since such constancy is the best possible ground for definitions of fundamental measurement units. This problem of constancy has received scant attention within the philosophy of science, but is the topic of the paper. The paper first highlights inevitable kinds of circularities, semantic and epistemic, that belongs to the search for constancy, and then discusses contingent dependencies between unit definitions. The New (...) SI proposal is criticized for not paying due attention to the fact that it defines units for one kind of quantity by means of a constancy that belongs to another. This inattention flaws the kilogram definition. The New SI definitions of the mole and the second neglect the distinction between discrete and continuous quantities; which make the definitions refer to constancies that are not invariants of nature.

Tarski avoids the liar paradox by relativizing truth and falsehood to particular languages and forbidding the predication to sentences in a language of truth or falsehood by any sentences belonging to the same language. The Tarski truth-schemata stratify an object-language and indefinitely ascending hierarchy of meta-languages in which the truth or falsehood of sentences in a language can only be asserted or denied in a higher-order meta-language. However, Tarski’s statement of the truth-schemata themselves involve general truth functions, and in particular (...) the biconditional, defined in terms of truth conditions involving truth values standardly displayed in a truth table. Consistently with his semantic program, all such truth values should also be relativized to particular languages for Tarski. The objection thus points toward the more interesting problem of Tarski’s concept of the exact status of truth predications in a general logic of sentential connectives. Tarski’s three-part solution to the circularity objection which he anticipates is discussed and refuted in detail. (shrink)

Epistemic circularity occurs when a subject forms the belief that a faculty F is reliable through the use of F. Although this is often thought to be vicious, externalist theories generally don't rule it out. For some philosophers, this is a reason to reject externalism. However, Michael Bergmann defends externalism by drawing on the tradition of common sense in two ways. First, he concedes that epistemically circular beliefs cannot answer a subject's doubts about her cognitive faculties. But, he argues, (...) subjects don't have such doubts, so epistemically circular beliefs are rarely called upon to play this role. Second, following Thomas Reid, Bergmann argues that we have noninferential, though epistemically circular, knowledge that our faculties are reliable. I argue, however, that Bergmann's view is undermined by doubts a subject should have and that there is no plausible explanation for how we can have noninferential knowledge that our faculties are reliable.

In this article, we address why our management of the economy, community and business has led to global warming and we discuss the importance of worldviews, ontology, epistemology and axiology in the search for alternative paths of development. We do this by focusing on the concept of Circular Economy. Circular Economy is often presented as a solution to the problems of a globalized economy in the form of over-exploitation of resources, climate change and pollution of the environment. Within the mainstream (...) economics paradigm, the aim is how to increase the effectiveness of resource extraction and utilization in order to maintain growth. We contrast this with the paradigm of Ecological Economics where the goal of the economy is to achieve and secure a higher quality of life. Circular Economy often side steps the deep ontological and epistemological questions we need to answer if we are to address the complex and interrelated environmental, economic and social problems we face today. This can be a limiting factor in the search for creative and long-term solutions. However, within the Circular Economy discourse, we find strands that critically engage with the foundations of mainstream Economics and so, innovative solutions for the society of the future are a possibility. We argue that to bring about a lasting solution to the interconnected social, economic and environmental problems, Circular Economy must engage with the ontological, epistemological and axiological foundations of mainstream economics. To further this argument, we apply Imre Lakatos’ ‘research program’ model to philosophy of science as our framework of analysis and draw lessons for business and communities. (shrink)

In a context of growing environmental challenges, circular economy (CE) business models appear necessary for business to contribute positively to the ecological transition. While platform business models have been identified as a new and promising model in CE, we still lack a fine-grained understanding of the critical capabilities involved in developing and scaling them. To fill this gap, we build on a single case study of Phenix, a French-based fast-growing start-up in the food industry, tackling the issue of food waste. (...) We identify three core managerial capabilities involved in the successful scaling of Phenix's business model. In addition to ecosystem orchestration capabilities, we identify two types of ambidextrous capabilities – forms of ambidexterity operating both at the organizational and at the institutional level. Our analysis highlights the importance of considering these capabilities in a bundle as they collectively contribute to the performance and scaling potential of the business model. We also call for an increased consideration of the role of institutional factors in shaping opportunities to design and scale profitable business models. (shrink)

Business orientation toward sustainable development goals and the circular economy are relevant research topics today in business theory and practice. The waste recycling sector is a key industry in the circular economy framework for promoting clean production and environmental sustainability. This study analyzes business performance in the recycling sector, focusing on efficiency indicators. The associations between firm efficiency and risk variables were also evaluated. The study goes through several methodological stages, including a Data Envelopment Analysis (DEA) multistage method and multivariate (...) modeling: tobit regression, bootstrap models, and generalized method of moments (GMM). The main results indicate that the average efficiency of waste recycling firms is at a medium level. Large-sized firms achieve higher levels of efficiency than medium-sized and small firms, supporting the economies of scale hypothesis. The evidence also suggests that risk variables (rating score and Zscore) and capital structure are key determinants of firm efficiency in the waste recycling industry. (shrink)

In his recent book, Reasons and Persons, Derek Parfit propounds a version of the psychological criterion of personal identity.1 According to the variant he adopts, the numerical identity through time of persons consists in non-branching psychological continuity no matter how it is caused. One traditional objection to a view of this sort is that it is circular, since psychological continuity presupposes personal identity. Although Parfit frequently denies the importance of personal identity, he considers his own psychological account of identity important (...) enough to attempt to defend it against the charge of circularity. The aim of this paper is to argue that Parfit's attempted defence is unsuccessful because it ultimately rests on an analysis of the unity of consciousness that is itself either circular or otherwise inadequate.

According to a common claim, a necessary condition for a collective action (as opposed to a mere set of intertwined or parallel actions) to take place is that the notion of collective action figures in the content of each participant’s attitudes. Insofar as this claim is part of a conceptual analysis, it gives rise to a circularity challenge that has been explicitly addressed by Michael Bratman and Christopher Kutz.1 I will briefly show how the problem arises within Bratman’s and (...) Kutz’s analyses, and then proceed to criticize some possible responses, including the ones proposed by Bratman and Kutz. My conclusion is that in order to avoid circularity and retain the features that are supposed to make this sort of account attractive, we need a notion of collectivity that does not presuppose intention. I suggest that we should make a distinction between collective and noncollective activity merely in terms of dispositions and causal agency. There are independent reasons to think that we actually possess such a distinct causal conception of collectivity. It is not necessary for the participants in a jointly intentional collective action to possess a stronger notion of their intended collective activity than this. In particular, they do not need to possess the concept of a jointly intentional collective action. (shrink)

Good informal arguments offer justification for their conclusions. They go wrong if the justifications double back, rendering the arguments circular. Circularity, however, is not necessarily a single property of an argument, but may depend on (a) whether the argument repeats an earlier claim, (b) whether the repetition occurs within the same line of justification, and (c) whether the claim is properly grounded in agreed‐upon information. The experiments reported here examine whether people take these factors into account in their judgments (...) of whether arguments are circular and whether they are reasonable. The results suggest that direct judgments of circularity depend heavily on repetition and structural role of claims, but only minimally on grounding. Judgments of reasonableness take repetition and grounding into account, but are relatively insensitive to structural role. (shrink)

In recent years, researchers and practitioners have increasingly paid attention to food waste, which is seen as highly unethical given its negative environmental and societal implications. Waste recovery is dependent on the creation of connections along the supply chain, so that actors with goods at risk of becoming waste can transfer them to those who may be able to use them as inputs or for their own consumption. Such waste recovery is, however, often hampered by what we call ‘circularity (...) holes’, i.e., missing linkages between waste generators and potential receivers. A new type of actor, the digital platform organization, has recently taken on a brokerage function to bridge circularity holes, particularly in the food supply chain. Yet, extant literature has overlooked this novel type of brokerage that exploits digital technology for the transfer and recovery of discarded resources between supply chain actors. Our study investigates this actor, conceptualized as a ‘circularity broker’, and thus unites network research and circular supply chain research. Focusing on the food supply chain, we adopt an interpretive inductive theory-building approach to uncover how platform organizations foster the recovery of waste by bridging circularity holes. We identify and explicate six brokerage roles, i.e., connecting, informing, protecting, mobilizing, integrating and measuring, and discuss them in relation to extant literature, highlighting novelties compared to earlier studies. The final section reflects on contributions, implications, limitations and areas for further research. (shrink)

The direct use of a physical law for the purpose of measurement creates a problem of circularity: the law needs to be empirically tested in order to ensure the reliability of measurement, but the testing requires that we already know the value of the quantity to be measured. This problem is discussed through some detailed examples of energy measurements in quantum physics; three major methods are analyzed in their interrelation, with a focus on the method of “material retardation.” It (...) seems that the only reasonable solution is to establish the law needed for the measurement by relying on an alternate method of measurement. This solution is also circular, since it amounts to letting different measurement methods justify each other. However, this circularity can be fruitful for the process of concept building; meaning can be created in a web of interconnected measurement methods. (shrink)

We consider domains with a natural property called top-circularity. We show that if such a domain satisfies either the maximal conflict property or the weak conflict property, then it is dictatorial. We obtain the result in Sato :331–342, 2010) as a corollary. Furthermore, it follows from our results that the union of a single-peaked domain and a single-dipped domain is dictatorial.

One of the gravest charges that has been brought against Hume’s essay “Of the Standard of Taste” is that of circularity. Hume is accused of defining good art in terms of “true judges,” and of defining true judges in terms of their ability to judge good art. First, I argue that Hume avoids circularity since he offers a way of identifying good art that is logically independent of the verdict of true judges. Second, I argue that this clarifies (...) an enduring puzzle in the scholarship on Hume’s essay: why he appears to offer not one but two standards of taste. Hume’s standard does not consist of general rules; however, Hume needs general rules to establish that some individuals’ tastes are more “delicate” than others’. (shrink)

I defend the view that circular definitions can be useful and illuminating by focusing on the fitting-attitudes analysis of value. This definition states that an item has value if and only if it is a fitting target of attitudes. Good items are the fitting targets of positive attitudes, and bad items are the fitting targets of negative ones. I shall argue that a circular version of this definition, defended by Rabinowicz and Rønnow-Rasmussen (2006), is preferable to its non-circular counterpart and (...) upholds reasonable standards of acceptability. The standards I will be discussing come from Humberstone (1997), who claims that definitions cannot be informative as long as they are inferentially circular. (shrink)

In this paper, we strengthen Hardy’s [1995] and Ketland’s [2005] arguments on the issues surrounding the self-referential nature of Yablo’s paradox [1993]. We first begin by observing that Priest’s [1997] construction of the binary satisfaction relation in revealing a fixed point relies on impredicative definitions. We then show that Yablo’s paradox is ‘ω-circular’, based on ω-inconsistent theories, by arguing that the paradox is not self-referential in the classical sense but rather admits circularity at the least transfinite countable ordinal. Hence, (...) we both strengthen arguments for the ω-inconsistency of Yablo’s paradox and present a compromise solution of the problem emerged from Yablo’s and Priest’s conflicting theses. (shrink)

Proponents of the predicate view of names explain the reference of an occurrence of a name N by invoking the property of bearing N. They avoid the charge that this view involves a vicious circularity by claiming that bearing N is not itself to be understood in terms of the reference of actual or possible occurrences of N. I argue that this approach is fundamentally mistaken. The phenomenon of ‘reference transfer’ shows that an individual can come to bear a (...) name in virtue of the referential practices of a group of speakers. I develop a picture of name-bearing which captures this fact by treating the extension of name as a function of the way that extension is represented in the presuppositions of groups of speakers. I show that though there is a form of circularity inherent in this approach, it is not vicious circularity. (shrink)

In this paper I defend epistemic circularity by arguing that the “No Self-Support” principle (NSS) is false. This principle, ultimately due to Fumerton ( 1995 ), states that one cannot acquire a justified belief in the reliability of a source of belief by trusting that very source. I argue that NSS has the skeptical consequence that the trustworthiness of all of our sources ultimately depends upon the trustworthiness of certain fundamental sources – sources that we cannot justifiably believe to (...) be reliable. This is a problem, I claim, because if the trustworthiness of all of our sources depends upon sources that we should not believe to be reliable, then a reflective individual should not trust any of his sources at all. The hidden cost of rejecting epistemic circularity is thus the unacceptable skeptical thesis that reflective individuals like you and I have no justified beliefs whatsoever. (shrink)

I develop a syntactic concept of circularity, which I call propositional circularity. With respect to a given use of an argument advanced as a statement of inference for the benefit of a reasoner R, if the direct and indirect premises R would have to accept in order to accept the conclusion includes the conclusion, then the collection of premises is propositionally circular. The argument fails to display a type of inference that R can perform. Appealing to propositional (...) class='Hi'>circularity, I articulate a sufficient condition for a use of an argument to beg the question, highlighting why question-begging is a defect. (shrink)

Considering the impact of COVID-19 outbreak on the foundation of our socio-economic and environmental systems, it is imperative to apply multi-faceted sustainability approaches for the current and post-pandemic era.

Proposing new concepts for the post-pandemic era that combine the built environment and sustainability techniques may provide an opportunity for better integration into the essence of sustainability.

This paper explores what happens if we construe evidentialism as a thesis about the metaphysical grounds of justification. According to grounding evidentialism, facts about what a subject is justified in believing are grounded in facts about that subject’s evidence. At first blush, grounding evidentialism appears to enjoy advantages over a more traditional construal of evidentialism as a piece of conceptual analysis. However, appearances are deceiving. I argue that grounding evidentialists are unable to provide a satisfactory story about what grounds the (...) evidential facts, and that this provides good reason to reject grounding evidentialism.

Mainstream epistemology has typically taken for granted a traditional picture of the metaphysics of mind, according to which cognitive processes (e.g. memory storage and retrieval) play out entirely within the bounds of the skull and skin. But this simple ‘intracranial’ picture is falling in- creasingly out of step with contemporary thinking in the philosophy of mind and cognitive science. Likewise, though, proponents of active exter- nalist approaches to the mind—e.g. the hypothesis of extended cognitition (HEC)—have proceeded by and large without (...) asking what epistemological ramifications should arise once cognition is understood as criss-crossing the bounds of brain and world. This paper aims to motivate a puzzle that arises only once these two strands of thinking are brought in contact with one another. In particular, we want to first highlight a kind of con- dition of epistemological adequacy that should be accepted by proponents of extended cognition; once this condition is motivated, the remainder of the paper demonstrates how attempts to satisfy this condition seem to inevitably devolve into a novel kind of epistemic circularity. At the end of the day, proponents of extended cognition have a novel epistemological puzzle on their hands. (shrink)

Can we show that our senses are reliable sources of information about the world? To show this, we need to establish that most of our perceptual judgments have been true. But we cannot determine these inductive instances without relying upon sense perception. Thus, it seems, we cannot establish the reliability of sense perception by means of an argument without falling into epistemic circularity. In this paper, I argue that this consequence is not an epistemological disaster. For this purpose, I (...) defend a normative claim that it is reasonable to accept the general reliability of our perceptual judgments, instead of a factual claim that our perceptual judgments are generally reliable. More specifically, I offer a normative practical argument which explains why it is reasonable to accept the general reliability of our perceptual judgments, even though we cannot establish the general reliability of our perceptual judgments by means of theoretical reasoning.

The thesis of this paper is that philosophers are often too hasty in rejecting justifications because the argument that yields the justification is circular. Circularity is distinguished from vicious circularity and several examples are examined in which a proposed justification is circular in a precise sense, but not viciously circular.

In this paper we investigate two purely syntactical notions ofcircularity, which we call ``self-application'''' and ``self-inclusion.'''' Alanguage containing self-application allows linguistic items to beapplied to themselves. In a language allowing for self-inclusion thereare expressions which include themselves as a proper part. We introduceaxiomatic systems of syntax which include identity criteria andexistence axioms for such expressions. The consistency of these axiomsystems will be shown by providing a variety of different models –these models being our circular languages. Finally we will show what (...) apossible semantics for these circular languages could look like. (shrink)

The validity of psychological measurement is crucially connected to a peculiar form of epistemic circularity. This circularity can be a threat when there are no independent ways to assess whether a certain procedure is actually measuring the intended target of measurement. This paper focuses on how Gustav Theodor Fechner addressed the measurement circularity that emerged in his psychophysical research. First, I show that Fechner's approach to the problem of circular measurement involved a core idealizing assumption of a (...) shared human physiology. Second, I assess Fechner's approach to this issue against the backdrop of his own epistemology of measurement and the measurement context of his time. Third, I claim that, from a coherentist and historicallysituated perspective, Fechner's quantification can be regarded as a first successful step of a longer-term quantification process. To conclude, I draw from these insights some general epistemological reflections that are relevant to current quantitative psychology. (shrink)

Reliabilism is an intuitive and attractive view about epistemic justification. However, it has many well-known problems. I offer a novel condition on reliabilist theories of justification. This method coherence condition requires that a method be appropriately tested by appeal to a subject’s other belief-forming methods. Adding this condition to reliabilism provides a solution to epistemic circularity worries, including the bootstrapping problem.

Recently, Kieran Setiya suggested that we might respond to evolutionary debunking arguments by arguing that, even if we cannot explain our reliability in ethics, we might justify believing ourselves reliable using a track record argument. Not surprisingly, several critics have claimed that this response is circular. I consider two senses in which they might be right, concluding that, though Setiya’s argument does not beg the question, it is epistemically circular. Perhaps surprisingly, its epistemic circularity need not prevent Setiya’s argument (...) from justifying its conclusion; nevertheless, I argue, reflection on this issue helps to bring out why realists would do well to eschew the strategy Setiya explores, focusing instead on showing that there is a suitable explanatory connection between our ethical beliefs and the facts.

There are possible worlds in which time is circular and finite in duration, forming a loop of, say, 12,000 years. There are also possible worlds in which time is linear and infinite in both directions and in which history is repetitive, consisting of infinitely many 12,000-year epochs, each two of which are exactly alike with respect to all intrinsic, purely qualitative properties. Could one ever have empirical evidence that one inhabits a world of the first kind rather than a world (...) of the second kind? We argue for the affirmative answer, contra Quine, Newton-Smith, and Bergström. Our argument for that conclusion differs from an argument for the same conclusion due to Weir. Weir’s argument is probabilistic and explicitly requires having evidence against determinism. Our argument is a direct appeal to the simplicity of laws, and it involves no probabilistic component. It is modeled on Shoemaker’s argument that one could have evidence of time without change. (shrink)

In this paper, I argue that Amie Thomasson’s Easy Ontology rests on a vicious circularity that is highly damaging. Easy Ontology invokes the idea of application conditions that give rise to analytic entailments. Such entailments can be used to answer ontological questions easily. I argue that the application conditions for basic terms are only circularly specifiable showing that Thomasson misses her self-set goal of preventing such a circularity. Using this circularity, I go on to show that Easy (...) Ontology as a whole collapses. (shrink)
