This work examines a foundational epistemic problem underlying much of modern physics: the fact that nearly all empirical access to physical systems is mediated by electromagnetic radiation. From atomic spectroscopy to scanning probe microscopy and observational cosmology, what experiments directly register are structured electromagnetic signals detected by macroscopic instruments. The paper argues that this radiation-based observational regime defines an ill-posed inverse problem. Many distinct physical configurations can give rise to identical detected electromagnetic patterns. As a result, the ontological narratives commonly (...) built from such data — involving particles, fields, spacetime geometry, and cosmic expansion — are systematically underdetermined by the measurements themselves. Through a unified analysis of atomic spectroscopy, scanning tunneling microscopy, and cosmological redshift, the paper shows that what experiments constrain are not internal structures, but interaction channels between hidden physical systems and the electromagnetic field. Stable radiation patterns reflect stable coupling interfaces, not necessarily unique underlying entities. The analysis is situated within the framework of Coherent Observational Epistemology (COE), which treats observation as the formation of coherence between independent localities via finite information channels. Within this framework, the persistence and reproducibility of physical models are explained by the stability of these coupling channels rather than by direct access to the internal constitution of matter or spacetime. The paper does not dispute the empirical success of modern physics. Instead, it clarifies the epistemic limits of radiation-based observation and argues for a structural, constraint-based interpretation that separates what is measured from what is inferred. (shrink)

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in (...) the nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

Even if spectrum inversion of various sorts is possible, spectrum inversion without a difference in representation is not. So spectrum inversion does not pose a challenge for the intentionalist thesis that, necessarily, within a given sense modality, if two experiences are alike with respect to content, they are also alike with respect to their phenomenal character. On the contrary, reflection on variants of standard cases of spectrum inversion provides a strong argument for intentionalism. Depending on one’s (...) views about the possibility of spectrum inversion, the impossibility of spectrum inversion without a difference in representation can also be used as an argument against a variety of reductive theories of mental representation.

The phenomenon of inverse linking, where a noun phrase embedded within another behaves with respect to binding as though it were structurally independent, has proven challenging for theories of the syntax–semantics interface. In this paper I show that, using an LF-movement style approach to the syntax–semantics interface, we can derive all and only the appropriate meanings for such constructions using no semantic operations other than function application and composition. The solution relies neither on a proliferation of lexical ambiguity nor on (...) abandoning the idea that pronouns denote variables, but rather on a straightforward (and standard) reification of assignment functions, which allows us to define abstraction operators within our models.

This paper formulates a bilateral account of harmony that is an alternative to one proposed by Francez. It builds on an account of harmony for unilateral logic proposed by Kürbis and the observation that reading the rules for the connectives of bilateral logic bottom up gives the grounds and consequences of formulas with the opposite speech act. I formulate a process I call 'inversion' which allows the determination of assertive elimination rules from assertive introduction rules, and rejective elimination rules (...) from rejective introduction rules, and conversely. It corresponds to Francez's notion of vertical harmony. I also formulate a process I call 'conversion', which allows the determination of rejective introduction rules from assertive elimination rules and conversely, and the determination of assertive introduction rules from rejective elimination rules and conversely. It corresponds to Francez's notion of horizontal harmony. The account has a number of features that distinguish it from Francez's. (shrink)

This article examines the phenomenon of epistemic inversion in contem- porary psychiatry, wherein diagnostic classification increasingly precedes and constrains theoretical development. We argue that this reversal—exemplified by symptom-based systems such as the DSM, leads to a loss of epistemic normativity and undermines the interpretive dimension of clinical reason- ing. Through a critical engagement with historical and philosophical tradi- tions (Canguilhem, Hacking) and contemporary debates in the philosophy of medicine (Khalidi, Kendler, Brigandt), we analyze the implications of object- led nosology (...) on the ontology and intelligibility of mental disorders. To re- construct epistemic coherence, we introduce the concept of constraint regimes structural, empirical, and projective—as a framework for understanding how diagnostic stability emerges from the interplay of normative, contextual, and biological factors. We advocate for a situated model of rationality that restores the mediating role of clinical expertise, challenges classificatory reification, and reorients psychiatry toward an interpretive and normatively robust epistemol- ogy.

This paper proposes a unified dependent type analysis of three puzzling phenomena: inversely linked interpretations, weak definite readings in possessives and Haddock-type readings. We argue that the three problematic readings have the same underlying surface structure, and that the surface structure postulated can be interpreted properly and compositionally using dependent types. The dependent type account proposed is the first, to the best of our knowledge, to formally connect the three phenomena. A further advantage of our proposal over previous analyses is (...) that it offers a principled solution to the puzzle of why both inversely linked interpretations and weak definite readings are blocked with certain prepositions.

The idea of an ?inversion principle?, and the name itself, originated in the work of Paul Lorenzen in the 1950s, as a method to generate new admissible rules within a certain syntactic context. Some fifteen years later, the idea was taken up by Dag Prawitz to devise a strategy of normalization for natural deduction calculi (this being an analogue of Gentzen's cut-elimination theorem for sequent calculi). Later, Prawitz used the inversion principle again, attributing it with a semantic role. (...) Still working in natural deduction calculi, he formulated a general type of schematic introduction rules to be matched ? thanks to the idea supporting the inversion principle ? by a corresponding general schematic Elimination rule. This was an attempt to provide a solution to the problem suggested by the often quoted note of Gentzen. According to Gentzen ?it should be possible to display the elimination rules as unique functions of the corresponding introduction rules on the basis of certain requirements?. Many people have since worked on this topic, which can be appropriately seen as the birthplace of what are now referred to as ?general elimination rules?, recently studied thoroughly by Sara Negri and Jan von Plato. In this study, we retrace the main threads of this chapter of proof-theoretical investigation, using Lorenzen's original framework as a general guide. (shrink)

This essay examines Nietzsche’s inversion of Terence’s formula “I am the closest to myself” into “Everyone is furthest from himself [Jeder ist sich selbst der Fernste]” (GM, Preface 1). In a contextual reading, I am going to ask how Nietzsche relates this formula to the difficulty of acquiring self-knowledge, as emphasized at the beginning ofOn theGenealogy of Morality. First, I argue that Nietzsche does not prohibit self-knowledge, but instead invites us to think about it differently; and second, I will (...) show that the formula according to which “everyone is furthest from himself” can also be understood as an injunction to keep the self always at a distance. I will link these two aspects by arguing that Nietzsche replaces self-knowledge in the classical sense by an interpretation of the self, and that this interpretation must never be thought of as an undertaking that seeks to reify their self. Nietzsche urges us to make ourselves into creative projects, even this will entail fiction and illusion. (shrink)

If people believe that some property is true of all members of a class such as sofas, then they should also believe that the same property is true of all members of a conjunctively defined subset of that class such as uncomfortable handmade sofas. A series of experiments demonstrated a failure to observe this constraint, leading to what is termed the inverse conjunction fallacy. Not only did people often express a belief in the more general statement but not in the (...) more specific, but also when they accepted both beliefs, they were inclined to give greater confidence to the more general. It is argued that this effect underlies a number of other demonstrations of fallacious reasoning, particularly in category-based induction. Alternative accounts of the phenomenon are evaluated, and it is concluded that the effect is best interpreted in terms of intensional reasoning [Tversky, A., & Kahneman, D.. Extensional versus intuitive reasoning: the conjunction fallacy in probability judgment. Psychological Review, 90, 293-315.]. (shrink)

The inversion principle for logical rules expresses a relationship between introduction and elimination rules for logical constants. Hallnäs & Schroeder-Heister (1990, 1991) proposed the principle of definitional reflection, which embodies basic ideas of inversion in the more general context of clausal definitions. For the context of admissibility statements, this has been further elaborated by Schroeder-Heister (2007). Using the framework of definitional reflection and its admissibility interpretation, we show that, in the sequent calculus of minimal propositional logic, the left (...) introduction rules are admissible when the right introduction rules are taken as the definitions of the logical constants and vice versa. This generalizes the well-known relationship between introduction and elimination rules in natural deduction to the framework of the sequent calculus. (shrink)

We investigate, for several modal logics but concentrating on KT, KD45, S4 and S5, the set of formulas B for which ${\square B}$ is provably equivalent to ${\square A}$ for a selected formula A (such as p, a sentence letter). In the exceptional case in which a modal logic is closed under the (‘cancellation’) rule taking us from ${\square C \leftrightarrow \square D}$ to ${C \leftrightarrow D}$ , there is only one formula B, to within equivalence, in this inverse image, (...) as we shall call it, of ${\square A}$ (relative to the logic concerned); for logics for which the intended reading of “ ${\square}$ ” is epistemic or doxastic, failure to be closed under this rule indicates that from the proposition expressed by a knowledge- or belief-attribution, the propositional object of the attitude in question cannot be recovered: arguably, a somewhat disconcerting situation. More generally, the inverse image of ${\square A}$ may comprise a range of non-equivalent formulas, all those provably implied by one fixed formula and provably implying another—though we shall see that for several choices of logic and of the formula A, there is not even such an ‘interval characterization’ of the inverse image (of ${\square A}$ ) to be found.

The possibility that what looks red to me may look green to you has traditionally been known as "spectrum inversion." This possibility is thought to create difficulties for any attempt to define mental states in terms of behavioral dispositions or functional roles. If spectrum inversion is possible, then it seems that two perceptual states may have identical functional antecedents and effects yet differ in their qualitative content. In that case the qualitative character of the states could not be (...) functionally defined. (shrink)

Inverted sensation arguments such as the inverted spectrum thought experiment are often criticized for relying on an unconstrained notion of 'qualia'. In reply to this criticism, 'qualia-free' arguments for inversion have been proposed, in which only physical changes happen: inversions in the world, such as the replacement of surface colors by their complements, and a rewiring of peripheral input cables to more central areas in the nervous system. I show why such constrained inversion arguments won't work. The first (...) problem is that the world lacks the symmetry required to invert physical properties in the way required. The second problem concerns 'rewiring'. Empirical evidence indicates that the rewirings are either impossible, or would not result in an inversion of sensation. I propose the deeper reason for the failure of constrained inversion arguments lies in the fact that sensations are not properties of brain states, but spread into the world and the body. (shrink)

Este ensayo trata de explicar en qué sentido la interpretación que hace Žižek de la inversión dialéctica de Hegel la ilumina como acontecimiento. En la medida en que en ella sustancia y sujeto sólo coinciden con su otro en su más interno desajuste, se pone al descubierto que ambos se preceden mutuamente: que la sustancia ya siempre se mira a través del sujeto, pero que, a la vez, la mirada del sujeto está siempre limitada por un punto ciego que testimonia (...) la precedencia de la sustancia. Es por esto por lo que en el (des-)encuentro dialéctico de los opuestos el “antes” y el “después” del tiempo se va a pique y, así, lo nuevo puede emerger verdaderamente. Finalmente, el trabajo clarifica la especificidad de la subversión que lleva a cabo el punto de vista dialéctico: al retrotraer a la negación auto-relacionada de la inversión dialéctica la identidad de cualquier posición, ésta resulta desenmascarada en su carácter ideológico a la vez que comprendida desde el necesario encubrirse de la negación. Se explica entonces que, lejos de pretender situarse en un terrero exterior al antagonismo y la ideología, este pensamiento se sepa siempre como parte comprometida. (shrink)

In this paper I examine whether representationalism can account for various thought experiments about colour inversions. Representationalism is, at minimum, the view that, necessarily, if two experiences have the same representational content then they have the same phenomenal character. I argue that representationalism ought to be rejected if one holds externalist views about experiential content and one holds traditional exter- nalist views about the nature of the content of propositional attitudes. Thus, colour inver- sion scenarios are more damaging to externalist (...) representationalist views than have been previously thought. More specifically, I argue that representationalists who endorse externalism about experiential content either have to become internalists about the content of propositional attitudes or they have to adopt a novel variety of externalism about the content of propositional attitudes. This novel type of propositional attitude externalism is investigated. It can be seen that adopting it forces one to reject Putnam. (shrink)

Suppose λ is a singular cardinal of uncountable cofinality κ. For a model M of cardinality λ, let No (M) denote the number of isomorphism types of models N of cardinality λ which are L ∞λ - equivalent to M. In [7] Shelah considered inverse κ- systems A of abelian groups and their certain kind of quotient limits Gr(A)/ Fact(A). In particular Shelah proved in [7, Fact 3.10] that for every cardinal μ there exists an inverse κ-system A such that (...) A consists of abelian groups having cardinality at most μ κ and card(Gr(A)/Fact(A)) = μ. Later in [8, Theorem 3.3] Shelah showed a strict connection between inverse κ-systems and possible values of No (under the assumption that $\theta^\kappa for every $\theta ): if A is an inverse κ- system of abelian groups having cardinality $\theta^\kappa for every $\theta ): for every nonzero $\mu or μ = λ κ there is a model M μ of cardinality λ with No(M μ ) = μ. In this paper we show: for every nonzero μ ≤ λ κ there is an inverse κ-system A of abelian groups having cardinality $2^\kappa and $\theta^{ for all $\theta when $\mu > \lambda$ ), with the obvious new consequence concerning the possible value of No. Specifically, the case No(M) = λ is possible when $\theta^\kappa for every $\theta.

This paper examines an important issue facing academia-pay inversion.

It then examines this issue from five ethical viewpoints: a legalistic perspective, ethical egoism, utilitarianism, distributive justice, and Kants deontological approach. As part of the discussion, the effect of the moral philosophy on the universitys corporate culture is examined, with attention given to morale and productivity. Finally, alternatives to pay (...) class='Hi'>inversion that universities may want to consider are discussed. (shrink)

As with faces, participants are better at discriminating upright bodies than inverted bodies. This inversion effect is reliable for whole figures, namely, bodies with heads, but it is less reliable for headless bodies. This suggests that removal of the head disrupts typical processing of human figures, and raises questions about the role of faces in efficient body discrimination. In most studies, faces are occluded, but the aim here was to exclude faces in a more ecologically valid way by presenting (...) photographic images of human figures from behind (about-facing), as well as measuring gaze to different parts of the figures. Participants determined whether pairs of sequentially presented body postures were the same or different for whole and headless figures. Presenting about-facing figures (heads seen from behind) and forward-facing figures with faces enabled a comparison of the effect of the presence or absence of faces. Replicating previous findings, there were inversion effects for forward-facing whole figures, but less reliable effects for headless images. There were also inversion effects for about-facing whole figures, but not about-facing headless figures. Accuracy was higher in the forward- compared to the about-facing conditions, but proportional dwell time was greater to bodies in about-facing images. Likewise, despite better discrimination of forward-facing upright compared to inverted whole figures, participants focussed more on the heads and less on the bodies in upright compared to inverted images. However, there was no clear relationship between performance and dwell time proportions to heads. Body inversion effects were found with about-facing whole figure and headless forward-facing figures, despite the absence of faces. With inverted whole figures, there was a significant relationship between performance and greater looking at bodies and less at heads suggesting that in more difficult conditions a focus on bodies is associated with better discrimination. Overall, the findings suggest that the visual system has greater sensitivity to bodies in their most experienced form, which is typically upright and with a head. Otherwise, the more a face is implied by the context, as in whole figures or forward- rather than about-facing headless bodies, the better the performance as holistic/configural processing might be stronger.

Although to live is to face problems, the general concept of a problem has been significantly understudied. So much so, that the publication of Polya’s delightful How to Solve It caused quite a stir. And, although the concept of a conceptual problem is philosophical because it is deep and occurs across fields, from mathematics to politics, no philosophers have produced any memorable studies of it. Moreover, the word ‘problem’ is absent from most philosophical reference works. There are plenty of texts (...) on particular problems such as those of evil and induction, but none on the general concept of a conceptual problem—as if it were not a problematic concept. Worse, we are seldom told that doing original mathematics, science or technology is to wrestle with original problems. Nor have we been told that the hardest problems are likely to be inverse, in that they go from effect to cause, or from sketch to implementation, or from conclusion to premises—as in diagnosing disease from symptoms, looking for a westward passage from Europe to Asia, and designing public policies to attack social issues. The existence of this significant gap in the philosophical literature justifies the publication of the present study. (shrink)

The article is based on the analysis and summary of the design process of the work of the Chinese author "Stone. Inversion. Vessel". It examines three key aspects of the development of environmental design. Firstly, it is a combination of modern technologies with aesthetic representations of traditional Chinese culture. Through the study of the project, it is demonstrated how traditional Chinese art can be combined with modern technologies when creating a design object. Secondly, the project highlights the features of (...) the development of design in the modern era. It is characterized by problems of volatility, uncertainty, complexity and ambiguity, which can be mitigated through interdisciplinary integration with the use of the latest technologies. Environmental design, thanks to the multifaceted concept of "environment", meets the conditions of development of the modern era. Thirdly, the article focuses on the fact that the communication of the subjects of the creative process is based on the images embodied in a specific project. Environmental design as an interdisciplinary field is based on the methods of different scientific fields, since the environment that changes under the influence of human activity is not the same. In the proposed article, the author uses the art criticism method when describing blue-and-green landscape painting, and also assigns a large role to the communicative method of sociology developed by the American scientist Harold Dwight Lasswell. The novelty of the research lies in the fact that the author was able to show the possibility of a harmonious combination of modern 3D modeling technologies with the traditional Chinese art of blue-and-green landscape painting (青绿山水 qīng lǜ shān shuǐ). In other words, a planar image turns into a design object, with the help of which can be realized various spatial combinations. Through artistic thinking, one can enjoy not only the functional, but also the aesthetic possibilities of the design object. So, in the described project, the author focuses on the imagination of the observer, forcing him to climb a mountain peak, but inside the building. This is how communication takes place between the author, the "viewer" and the project itself. The image is the basis of communication between various objects of the environment involved in the design process. The creative process combines the material (functional) and spiritual (image-induced) needs of a person. Environmental design, through the synthesis of spiritual and material, establishing communication between design objects and integrating disciplines through the prism of an image, explores how design affects human activity.

In recent years, inverse spectra were investigated with imaging optics and a quantitative description with radiometric units was suggested. It could be shown that inverse spectra complement each other additively to a constant intensity level. Since optical intensity in radiometric units is a power area density, it can be expected that energy densities of inverse spectra also fulfill an inversion equation and complement each other. In this contribution we report findings on a measurement of the power area density of (...) inverse spectra for the near ultraviolet, visible and the infrared spectral range. They show the existence of corresponding spectral regions ultra-yellow and infra-cyan in the inverted spectrum and thereby present additional experimental evidence for equivalence of inverse spectra beyond the visible range.

Introduction: It is essential to detect sacroiliitis earlier to decrease morbidity and unwanted complications such as ankylosing of sacroiliac joints. In recent studies, magnetic resonance imaging (MRI) serves as a key diagnostic tool for identifying sacroiliitis and is now included in the diagnostic criteria. We aim to detect the utility of diffusion-weighted imaging on the MRI in diagnosing sacroiliitis and measure ADC values for the response to treatment in future studies. Materials -methods: There were 39 patients (16 male, 20 female). (...) A 1.5 Tesla MR device with a pelvic coil was used. The sequences were T1 (before and after intravenous contrast administration of gadolinium), T2-weighted fast field echo, short tau inversion recovery (STIR), diffusion-weighted (DW) images, and apparent diffusion coefficient (ADC) mapping. Sacroiliac joints were divided into four quadrants, and two radiologists interpreted all the sequences by giving scores from 0 to 3 depending on bone marrow edema from none to severe. The concordance of scores assigned to STIR, T1-weighted gadolinium-enhanced images, ADC mapping, and diffusion-weighted MR images was evaluated by calculating intraclass correlation coefficients. Results: A statistically significant positive correlation was observed between the activity scores derived from short tau inversion recovery (STIR) and other magnetic resonance (MR) sequences, namely T1-weighted gadolinium-enhanced images, apparent diffusion coefficient (ADC) mapping, and diffusion-weighted MR images. Conclusion: Active bone marrow abnormalities were identified with comparable efficacy using STIR imaging and other MR sequences (T1W-Gad, ADC mapping, DW-MR). In our study, we tried to emphasize the role of the diffusion-weighted images near the other sequences. Diffusion is a fast, easy-applied sequence. After increased experience in the diffusion-weighted images, routine application of this sequence will increase, and even becoming one of the diagnostic criteria will be inevitable. The difference in DWI from the other sequences is that it is measurable. The response to treatment may be followed up by ADC values. (shrink)

Responsiveness to electoral opinions is one of the hallmarks of democratic governance. We focus on a particularly strong type of unresponsiveness, viz., one where the complete inversion of all preferences in the electorate is accompanied with no change in the electoral outcome.

We set out to find out whether the paradox can (...) be encountered when using various procedures under a restricted Condorcet domain, viz., one where a Condorcet winner exists and is elected by the procedure under study.

The standard account of weakness of will identifies it with akrasia, that is, with action against one's best judgment. Elsewhere I have argued that weakness of will is better understood as over-readily giving up on one's resolutions. Many cases of weak willed action will not be akratic: in over-readily abandoning a resolution an agent may well do something that they judge at the time to be best. Indeed, in so far as temptation typically gives rise to judgment shift -- to (...) a tendency to change one's judgment so that one values the tempting option as the best -- weak willed action will typically be akratic. But conversely, strong willed action now looks as though it will be akratic. I argue though that it need not be, once we distinguish between actual judgment, and dispositions to judge. Within this framework, the issue of inverse akrasia looks rather different. I argue that whilst Huckleberry Finn plausibly does show weakness of will in abandoning his resolve to turn Jim in, it is far from clear that he is akratic: a point brought out well in Twain's later additions to the text. Whilst cases of inverse akrasia are clearly theoretically possible, I suggest that, given cognitive dissonance mechanisms, they are unlikely to be very common. (shrink)

A study on the concept of inversion in Marx's critique of capitalism. This volume includes references to Hegel on the unity of subject and object, Smith and Ricardo on the falling rate of profit, and the concepts of capitalism and socialism.

No one before Platter and Kepler proposed retinal reception of an inverted visual image. The dominant tradition in visual theory, especially that of Alhazen and his Western followers, subordinated the intra-ocular geometry of visual rays to the requirement for an upright image and to preconceptions about the precise nature of the visual spirit and its part in vision. Henry of Langenstein and an anonymous glossator in the late Middle Ages proposed alternatives to Alhazen, including the suggestion of double inversion (...) of the image. Leonardo da Vinci was aware of both Alhazen's theory and Henry's contradiction, but perhaps not of the anonymous hypothesis of double inversion. Leonardo's visual ‘theory’ has more the character of a critique than of a theoretical alternative, and he did not transcend the medieval concept of visual spirit. (shrink)

Paper explores the controversial relationship between Schelling and Hegel with respect to the role of negativity.

By discussing (a) the negativity of reflection, (b) the ontological interpretation of the transcendental object and (...)

The article advances the notion that contemporary philosophy exists not as an ontology, but rather as an anthropology. The author posits that our understanding of being is contingent upon our comprehension of the human condition. Through an examination of the intellectual debate between M. Foucault and A. Badiou, the author demonstrates that I. Kant was the pioneer in European philosophy to interrogate the essence of humanity, thereby inaugurating an anthropological mode of philosophical thought. Building upon Kant’s proposition, the author presents (...) the intriguing hypothesis that the essence of humanity, or humanitas, is encapsulated within its capacity for hallucination, or hallucinatas. This perspective leads the author to introduce the novel philosophical concepts of “hallucenosis” and “explosion of hallucinations.” Here, “hallucenosis” refers to a collective of individuals engaged in a shared dream state, while “explosion of hallucinations” denotes the primal self-representation of humans as depicted in the rock art of the late Paleolithic era. The author gives particular emphasis to the concept of “double inversion” in human nature, a notion originally proposed in Russian philosophy by B.F. Porshnev and Yu.M. Borodai. Double inversion is interpreted as the emergence of self-consciousness, on one hand, and a speech event, on the other. The author further develops the idea that in contemporary human behavior, consciousness and intelligence are fundamentally disconnected. The conclusion drawn is that while intelligence facilitates animal existence in space, consciousness enables human life in time. In the author’s view, to hallucinate is essentially to live in time. The article substantiates the claim that organic intelligence and human intelligence operate within distinct sensoriums. Meanwhile, artificial intelligence, lacking its own sensorium, is argued to be non-existent in this context. (shrink)

Integrating information systems has become a key goal for governments worldwide. Systems of “authentic registers,” for instance, provide government agencies with information from databases acknowledged as the only legitimate sources of data. Concerns are thus arising about the risks for democratic accountability constituted by more and more integrated governmental IS. Studies call for a new research agenda that investigates the redistribution of authority and accountability entailed by interoperable IS. This article contributes to this endeavor by suggesting the “vectorial glance” as (...) a research framework that works along two lines. First, by recovering the science and technology studies notion of “infrastructural inversion,” it looks at the technical minutiae of interoperability projects as strategic sites where institutional shifts—and eventually state transformation—can become visible. Second, by defining interoperability as a performative process of boundary reordering, it opens research to the possibility that institutional identities be reconstituted along different lines. Just as vector graphics are based on paths that lead through control points without being bound to underlying pixels, so the vectorial glance runs across boundaries without implicitly assuming that they are immutable and/or a priori relevant for the analysis. This article draws on a case study observed while working at a major project of civil registers integration in Italy. (shrink)

William Lane Craig has argued that there cannot be actual infinities because inverse operations are not well-defined for infinities.

Mit seinem Begriff der Aufklärung konterkariert Kant das Verständnis seiner Zeitgenossen. An die Stelle der Auffindung und Verbreitung wahrer Erkenntnisse sowie des Ausmerzens von Irrtümern und Vorurteilen setzt er den Fortschritt des selbständigen Vermögensgebrauchs der Menschen. Der Beitrag zeigt, dass Kant seinen Begriff der Unmündigkeit zwar aus dem Vorurteilsdiskurs der Aufklärung entwickelt, aber dabei eine Inversion ihrer Herrschaftsmetaphorik vornimmt. Die nur übertragen verstandene innere Herrschaft der Vorurteile der aufklärerischen Tradition kehrt Kant zur ganz tatsächlichen Herrschaftsbeziehung von Vormundschaft und Unmündigkeit (...) um, und somit einen epistemischen Diskurs in einen sozialen. Diese Sozialphilosophie ist systematisch in Kants Anthropologie zu verorten, die sich nicht in erster Linie mit der praktischen Vernunft auseinandersetzt, sondern mit den faktischen Beziehungen von Menschen und dem Einfluss ihres Vermögensgebrauchs aufeinander. Die Unmündigkeit als ontogenetische conditio humana hält hierbei die systematische Erkenntnis bereit, dass Beherrschbarkeit ganz zentral mit der Temporalität des menschlichen Lebens zusammenhängt.

As a consequence we show the impossibility of a generalized inverse limit X-reflection result for X ⊆ Vλ+1, thus focusing the (...) study of L generalizations on L. (shrink)

Spectrum inversion is a thought experiment, and I would wager that there is no better diagnostic test to the disciplinary affiliation of a randomly selected member of the audience than your reaction to a thought experiment. It is a litmus test. If you find that you are paying close attention, subvocalizing objections, and that your heart-rate and metabolism go up, you have turned pink: you are a philosopher. If on the other hand the thought experiment leaves you cold, and (...) you wonder why otherwise sensible people would worry about such things, you have turned blue and you are a psychologist.

In the pure powers ontology (PPO), basic physical properties have wholly dispositional essences. PPO has clear advantages over categoricalist ontologies, which suffer from familiar epistemological and metaphysical problems. However, opponents argue that because it contains no qualitative properties, PPO lacks the resources to individuate powers, and generates a regress. The challenge for those who take such arguments seriously is to introduce qualitative properties without reintroducing the problems that PPO was meant to solve. In this paper, I distinguish the core claim (...) of PPO: (i) basic physical properties have dispositional essences, from a hitherto unnoticed assumption: (ii) the dispositional essences of basic physical properties exclusively involve type-causal relations to other basic physical properties. I reject (ii), making room for a structuralist ontology in which all basic physical properties are pure powers, individuated by their places in a causal structure that includes not only other powers, but also physically realized qualitative properties such as shapes, patterns and structures. Such qualities individuate pure powers in the way that non-mental input and output properties individuate realized mental properties in functionalist theories of mind, except that here it is basic physical powers that are individuated by relations to realized non-powers. I distinguish one Platonic and two Aristotelian version of this theory, and argue that the Aristotelian versions require that grounding is not always a relative fundamentality relation, because the powers ground the qualities that individuate them. By considering ontic structural realism, I argue that symmetric grounding is the best way to make sense of relational individuation in structuralist ontologies, and is therefore no additional commitment of the one proposed here.

Philosophical (p-) zombies are constructs that possess all of the behavioral features and responses of a sentient human being, yet are not conscious. P-zombies are intimately linked to the hard problem of consciousness and have been invoked as arguments against physicalist approaches. But what if we were to invert the characteristics of p-zombies? Such an inverse (i-) zombie would possess all of the behavioral features and responses of an insensate being yet would nonetheless be conscious. While p-zombies are logically possible (...) but naturally improbable, an approximation of i-zombies actually exists: individuals experiencing what is referred to as “anesthesia awareness.” Patients under general anesthesia may be intubated (preventing speech), paralyzed (preventing movement), and narcotized (minimizing response to nociceptive stimuli). Thus, they appear—and typically are—unconscious. In 1-2 cases/1000, however, patients may be aware of intraoperative events, sometimes without any objective indices. Furthermore, a much higher percentage of patients (22% in a recent study) may have the subjective experience of dreaming during general anesthesia. P-zombies confront us with the hard problem of consciousness—how do we explain the presence of qualia? I-zombies present a more practical problem—how do we detect the presence of qualia? The current investigation compares p-zombies to i-zombies and explores the “hard problem” of unconsciousness with a focus on anesthesia awareness. (shrink)

Given a 1-ary sentence operator , we describe L - another 1-ary operator - as as a left inverse of in a given logic if in that logic every formula is provably equivalent to L. Similarly R is a right inverse of if is always provably equivalent to R. We investigate the behaviour of left and right inverses for taken as the operator of various normal modal logics, paying particular attention to the conditions under which these logics are conservatively extended (...) by the addition of such inverses, as well as to the question of when, in such extensions, the inverses behave as normal modal operators in their own right.

This article1 deals with a well-known but still ill-explained fact about German, namely scope inversion under a particular accent contour, as illustrated with the following examples, where “/” and “\” stand for rising and falling accent: (a) Mindestens ein Stu- dent hat jeden Roman gelesen, lit. ‘at least one student has every novel read’, with the reading “For at least one student x: x read every book”, and (b) Mindestens /EIN Student hat \JEDen Roman gelesen, with the additional reading (...) “For every novel y: at least one student read y”. I will derive the scope inversion in this reading from general principles of scope assignment and focus marking in German. In particular, I will argue that focus is assigned to constituents that precede the verbal predicate, which leads to syntactic configurations that in turn result in ambiguous interpretations. This explanation must be couched in a framework of derivational economy that favors shorter derivations. It is argued that the relevant comparison class is defined with respect to phonological form, not, as has been suggested for English, with respect t o identity of semantic interpretation, and that this may be a general property of “free” word order languages.

Non‐reflectivist real self views claim that people are morally responsible for all and only those bits of conduct that express their true values and cares, regardless of whether they have endorsed them or not. A phenomenon that is widely cited in support of these views is inverse akrasia, that is, cases in which a person is praiseworthy for having done the right thing for the right reasons despite her considered judgment that what she did was wrong. In this paper I (...) show that non‐reflectivist real self views are problematic by focusing on the related but neglected phenomenon of inverse enkrasia, which occurs when an agent commits wrongdoing by following a mistaken evaluative judgment that, unbeknownst to her, runs contrary to her true values and cares. Intuitively, inverse enkratics are blameworthy for their actions although the latter don't express their real selves; therefore, non‐reflectivist real self views are false. I assess the implications of this result for the viability of the quality of will paradigm and conclude that the latter survives unscathed to the problems besetting real self views. The lesson is that defenders of the quality of will paradigm should stop talking about real selves altogether. (shrink)

According to the Contingency Theory of Laws, if there are possible worlds in which it is a law that all Fs are G, there are also possible F-containing worlds in which it is not. I argue here that the theory is forced to accept the possibility of nomic inversion: i.e. pairs of properties that have their actual nomic roles swapped in some possible world. Such inversions cannot be ruled out on grounds of logical or metaphysical inconsistency, and therefore – (...) since nomic inversion is counterintuitive – the Contingency Theory is undermined.

We study inversions of the jump operator on ${\mathrm{\Pi }}_{1}^{0}$ classes, combined with certain basis theorems. These jump inversions have implications for the study of the jump operator on the random degrees—for various notions of randomness. For example, we characterize the jumps of the weakly 2-random sets which are not 2-random, and the jumps of the weakly 1-random relative to 0′ sets which are not 2-random. Both of the classes coincide with the degrees above 0′ which are not 0′-dominated. A (...) further application is the complete solution of [24, Problem 3.6.9]: one direction of van Lambalgen's theorem holds for weak 2-randomness, while the other fails. Finally we discuss various techniques for coding information into incomplete randoms. Using these techniques we give a negative answer to [24, Problem 8.2.14]: not all weakly 2-random sets are array computable. In fact, given any oracle X, there is a weakly 2-random which is not array computable relative to X. This contrasts with the fact that all 2-random sets are array computable. (shrink)

Visual space can be distinguished from physical space. The first is found in visual experience, while the second is defined independently of perception. Theorists have wondered about the relation between the two. Some investigators have concluded that visual space is non-Euclidean, and that it does not have a single metric structure. Here it is argued that visual space exhibits contraction in all three dimensions with increasing distance from the observer, that experienced features of this contraction are not the same as (...) would be the experience of a perspective projection onto a fronto-parallel plane, and that such contraction is consistent with size constancy. These properties of visual space are different from those that would be predicted if spatial perception resulted from the successful solution of the inverse problem. They are consistent with the notion that optical constraints have been internalized. More generally, they are also consistent with the notion that visual spatial structures bear a resemblance relation to physical spatial structures. This notion supports a type of representational relation that is distinct from mere causal correspondence. The reticence of some philosophers and psychologists to discuss the structure of phenomenal space is diagnosed in terms of the simple materialism and the functionalism of the 1970s and 1980s. (shrink)
