Zwart and Franssen’s impossibility theorem reveals a conflict between the possible-world-based content-definition and the possible-world-based likeness-definition of verisimilitude. In Sect. 2 we show that the possible-world-based content-definition violates four basic intuitions of Popper’s consequence-based content-account to verisimilitude, and therefore cannot be said to be in the spirit of Popper’s account, although this is the opinion of some prominent authors. In Sect. 3 we argue that in consequence-accounts , content-aspects and likeness-aspects of verisimilitude (...) are not in conflict with each other, but in agreement . We explain this fact by pointing towards the deep difference between possible-world- and the consequence-accounts, which does not lie in the difference between syntactic (object-language) versus semantic (meta-language) formulations, but in the difference between ‘disjunction-of-possible-worlds’ versus ‘conjunction-of-parts’ representations of theories. Drawing on earlier work, we explain in Sect. 4 how the shortcomings of Popper’s original definition can be repaired by what we call the relevant element approach. We propose a quantitative likeness-definition of verisimilitude based on relevant elements which provably agrees with the qualitative relevant content-definition of verisimilitude on all pairs of comparable theories. We conclude the paper with a plea for consequence-accounts and a brief analysis of the problem of language-dependence (Sect. 6). (shrink)

2 Popper's Logical Definition of Verisimilitude. 3 Popper's Probabilistic Definition of Verisimilitude. 4 Conclusion.

Zwart and Franssen’s impossibility theorem reveals a conflict between the possible-world-based content-definition and the possible-world-based likeness-definition of verisimilitude. In Sect. 2 we show that the possible-world-based content-definition violates four basic intuitions of Popper’s consequence-based content-account to verisimilitude, and therefore cannot be said to be in the spirit of Popper’s account, although this is the opinion of some prominent authors. In Sect. 3 we argue that in consequence-accounts, content-aspects and likeness-aspects of verisimilitude are (...) not in conflict with each other, but in agreement. We explain this fact by pointing towards the deep difference between possible-world- and the consequence-accounts, which does not lie in the difference between syntactic versus semantic formulations, but in the difference between ‘disjunction-of-possible-worlds’ versus ‘conjunction-of-parts’ representations of theories. Drawing on earlier work, we explain in Sect. 4 how the shortcomings of Popper’s original definition can be repaired by what we call the relevant element approach. We propose a quantitative likeness-definition of verisimilitude based on relevant elements which provably agrees with the qualitative relevant content-definition of verisimilitude on all pairs of comparable theories. We conclude the paper with a plea for consequence-accounts and a brief analysis of the problem of language-dependence. (shrink)

In this paper, we show that Arrow’s well-known impossibility theorem is instrumental in bringing the ongoing discussion about verisimilitude to a more general level of abstraction. After some preparatory technical steps, we show that Arrow’s requirements for voting procedures in social choice are also natural desiderata for a general verisimilitude definition that places content and likeness considerations on the same footing. Our main result states that no qualitative unifying procedure of a functional form can simultaneously satisfy (...) the requirements of Unanimity, Independence of irrelevant alternatives and Non-dictatorship at the level of sentence variables. By giving a formal account of the incompatibility of the considerations of content and likeness, our impossibility result makes it possible to systematize the discussion about verisimilitude, and to understand it in more general terms.

Theories of verisimilitude have routinely been classified into two rival camps—the content approach and the likeness approach—and these appear to be motivated by very different sets of data and principles. The question thus naturally arises as to whether these approaches can be fruitfully combined. Recently Zwart and Franssen (Synthese 158(1):75–92, 2007) have offered precise analyses of the content and likeness approaches, and shown that given these analyses any attempt to meld content and likeness orderings violates some (...) basic desiderata. Unfortunately their characterizations of the approaches do not embrace the paradigm examples of those approaches. I offer somewhat different characterizations of these two approaches, as well as of the consequence approach (Schurz and Weingartner (Synthese 172(3):415–436, 2010) which happily embrace their respective paradigms. Finally I prove that the three approaches are indeed compatible, but only just, and that the cost of combining them is too high. Any account which combines the strictures of what I call the strong likeness approach with the demands of either the content or the consequence approach suffers from precisely the same defect as Popper’s—namely, it entails the trivialization of truthlikeness. The downside of eschewing the strong likeness constraints and embracing the content constraints alone is the underdetermination of the concept of truthlikeness. (shrink)

The main objective of this work was to produce a scientifically reasonable definition of God. The rationale was to generate a definition for filling a small part of the spiritual vacuum of the 21st century and thus initiate a new understanding of the Intelligence that permeates the cosmos with mystery, love, order, direction and morals. This resulted in the following definition: “God may be a-humanly incomprehensible-eternal cosmic existence, intimately related to the endlessness of space, to the nature (...) of the deepest common substance of matter and energy, to this common substance’s unceasing motion responsible for time, and to the basic laws of their allness, letting love transform this allness to an ordered Multiverse with a Soul: the—scientifically approachable—Soul of Multiverse inspired to guard these laws and equip their order with direction and morals while imbuing the cosmos with the potential of lives evolving, at the right spatial and temporal distances, to embrace the sense of the divine, thus justifying the existence of God.” The likely neural circuitry for sensing God in the human brain was identified as a network for spiritual data flow across the conscious and subconscious layers of the association cortical cognitive system exchanging data with the prefrontal cortical Self-Ken and modulated by inputs from the emotional and motivational systems of the brain. To study this mental process, the design of a God-Experience Monitor was also developed: a comfortably wearable combination of EEG and audiovisual-recorders tailored to at least partially capture the individual experiences of God anytime and at the very “genius loci” of such experiences.

During the last decades the question of defining life has gained increased interest but, at the same time, the difficulty in reaching consensus on a possible answer has led many to skeptical positions. This, in turn, has raised a wider debate about why defining life is so hard and controversial. Such a debate introduces additional aspects to be considered, like the role and nature of a definition of life itself. In this paper, we will focus on those aspects, arguing (...) that progress can be made if we conceive definitions of life as open heuristic tools that contribute to develop specific research strategies in the biological sciences and, more generally, to increase our understanding of life’s complexity. In contrast with pragmatic or operationalist approaches, we will defend that definitions of life comprise a set of ontological assumptions, together with an inherent unifying vocation, so they should be subject to comparison and critical assessment, closely related to the success or failure of the corresponding research programs, but also to the success or failure in establishing well-grounded interconnections among the latter. We consider that the search for a more coherent, integrated and generalized theory of biology cannot be pursued without keeping an empirical standpoint, and the exercise of defining life should not be taken as an obstacle but as a valuable instrument to achieve that goal.

The concept of verisimilitude is an indispensable tool for the fallibilist and realist epistemology. Part of the argument for this thesis consists in the important applications of this notion within the history and philosophy of science. But perhaps the harder part is to convince a sceptical reader of the existence of this concept. A general programme for defining and estimating degrees of truthlikeness for various kinds of scientific statements is outlined in some detail. Ten years after Miller's and Tichy's (...) refutation of Popper's attempted definition, this paper reviews recent developments and debates, and concludes that the treatment the Popperian problem with Carnapian logical tools leads to a new synthesis which turns out to formally contain Levi's theory of epistemic utilities as a special case.

The consensus view in the literature is that, according to Kant, definitions in philosophy are impossible. While this is true prior to the advent of transcendental philosophy, I argue that with Kant's Copernican Turn definitions of some philosophical concepts, the categories, become possible. Along the way I discuss issues like why Kant introduces the ‘Analytic of Concepts’ as an analysis of the understanding, how this faculty, as the faculty for judging, provides the principle for the complete exhibition of the categories, (...) how the pure categories relate to the schematized categories, and how the latter can be used on empirical objects.

After the publication of Marshall’s theorem (2009), it has been widely accepted that the intrinsic/extrinsic distinction cannot be analyzed in broadly logical terms, but instead requires appealing to more robust metaphysical notions like grounding, naturalness or duplication. However, in this article I will defend that this is not so. Instead of showing the limitations of Marshall’s undoubtedly impressive result, I will present here a broadly logical definition of the intrinsic/extrinsic distinction, and show that it is extensional adequate regardless of (...) our preferred conception of property identity.

In this text, Bataille clarifies his idea of the ‘excluded part’, i.e. that which is left behind by science. Bataille seeks to create an approach that would challenge the abstracted method of science, which presents the world as idealized and homogeneous. The aim of Bataille’s ‘science of the heterogeneous’ is to shed light on the unproductive expenditure of life, which moves between the sacred and the unclean. In pursuing this, he debunks the common idea that what is profane is already (...) impure and vice versa. This text is notable for the new vocabulary that Bataille introduces in order to define heterology. Terms like heterodoxy, agiology and scatology rehabilitate the ideas of the unclean and the profane by structuring them in a new discourse, in which the excluded part is taken as the foundation for the new science of the impossible. Finally, the text shows how Bataille articulates this new science through providing examples largely from the study of religion and psychoanalysis. (shrink)

Kerridge et al recently published a paper in the journal about organ transplantation and the diagnosis of death.1 Although I appreciate the authors’ efforts to present their arguments about such a controversial issue, I found some inconsistencies in this article that I would like to discussWhen Kerridge and his collaborators discussed the origins of the concept of brain death , they emphasised that after the report of the medical consultants on the diagnosis of death to the US President’s Commission was (...) published in 1981,2 clinicians equated the concept of BD with brainstem death. In fact, the brainstem criterion was first proposed by Mohandas and Chou in Minnesota, in 1971.3 The Minnesota criteria inspired the UK code, which was mainly adopted in UK commonwealth countries.4 This view was afterwards powerfully defended by Christopher Pallis.5 After the US President’s Commission report,2 a lot of countries, and most US states, accepted the whole brain, and not the brainstem, criterion.6Regarding the “dead donor rule”, with the advent of transplant surgery, interest in definitions and diagnosis of death based on brain formulations really acquired a new urgency. None the less, it is important to point out that the concept of BD as death of the individual, did not appear to benefit organ transplantation, but was a consequence of the development of intensive care. As Pallis emphasised, if organ transplant techniques had never been developed, intensive care procedures would have provided the possibility of supplying life support to those cases with destroyed brains and preserved heart function, and physicians would need to face the clinical syndrome called BD.5 When French neurophysiologists and neurologists described the death of the nervous system and coma dépassé, organ transplant techniques were only in the very early stages of development. ….

On the definition of genre of Dostoevsky's works. The article mostly addresses Dostoevsk's own definitions of genres of his works, either explicated in the texts (subtitles, prefaces) or contained in the writer's letters; or rather the relationship between the scholarly strategies of defining genres and the writer's own view, as evidenced. by subtitles which, in some sense, are part of the text (in nearly, but not precisely, the same way as the titles themselves are). The writer's own definitions, then, (...) can be regarded as possible objects of the scholarly interpretation. Agreement, or lack thereof, between the author's and the scholars' definitions may be due both to similarity vs dissimilarity between the definition standards inherent in the respective epochs and to specific interpretation aspects. In the latter case, agreement is more cornman in studies focusing on vastly different problems unrelated to genre, whereas disagreement is more frequent in studies concerned with the genres of Dostoevsky's works. One of the reasons why his own definitions must be critically revisited is that certain titles of his workscan be basically viewed as subtitles or genre definitions insofar as they in some way define the variety of the text regardless of the underlying criterion: narrative, "discourse", type of source, genre, or genre variety. Indeed, both these subtitles and, sometimes, the writer's own genre definitions tum out to be pretense, an imitation of "standard" subtitles or genre definitions, respectively. Titles themselves sometimes look like subtitles, thus "exposing the device" and demonstrating this mimicry not merely by violating semantic and syntactic relations in the case of subtitles (sign/name/title/ subtitle and virtual reference/"reality" of text - and relationships such as those between title and subtitle; title and the principal text; and subtitle and principal text), but also by the fact that their position is "marked". Dostoevsky not just failed to follow his own "final genre definitions" within the text, as reflected in the subtitles, and not just changed them repeatedly in his letters, but in the official documents, too, he sometimes defined genres in a way which did not agree with either the subtitles or his own definitions given in his letters.Dostoevsky frequently changed the genre definitions not merely during his work on a text, which would be only natural, and not merely many years after it had been completed, published, revised, and republished (which might be ascribed to memory errors), but also shortly after the completed manuscript had been shipped to the publishers or after the text had been published or republished. While the logic underlying these changes must be studied and interpreted, it is evident that the scholars are often unable to accept the author's own "final genre definitions" both because these are often unavailable in subtitles, and because of the "Proteic" nature of their use by the writer in various contexts.

Physicalism is incompatible with what is known as the possibility of zombies, that is, the possibility of a world physically like ours, but in which there are no conscious experiences. But it is compatible with what is known as the possibility of ghosts, that is, the possibility of a world which is physically like ours, but in which there are additional nonphysical entities. In this paper we argue that a revision to the traditional definition of physicalism designed to accommodate (...) the possibility of ghosts inadvertently accommodates what is known as the possibility of inverted spectra, that is, the possibility of a world which is physically like ours, but in which colour experience is inverted. This consequence is unwelcome, because it is widely agreed that the possibility of inverted spectra is incompatible with physicalism. We argue for a revised definition of physicalism which resolves this problem. We then use our definition to argue that physicalism is not compatible with what is known as the possibility of blockers, that is, the possibility of a world which is physically like ours, but in which additional nonphysical entities have prevented the existence of conscious experience. This undermines Stephan Leuenberger's attempt to defend physicalism from arguments which purport to establish the possibility of zombies. (shrink)

As was mentioned by Nicolas Lori in his (Found Sci, 2010 ) commentary, the definition of Information in Physics is something about which not all authors agreed.

The problem of definition of knowledge has been discussed in the tradi-tion of kalām and philosophy. Especially with the inclusion of logic definition theory in the discipline of kalām, the definitions put forward were criticized by later thinkers. Shams al-Dīn al-Samarqandī (d. 722/1322), who was included in this discussion, which was mainly shaped around the question of whether knowledge is necessary (ḍarūrī) or acquired (kasbī), wrote the ideal definition and features in al-Meārif and commentary of Avicenna’s al-Ishārāt (...) wa altanbīhāt. In addition, Shams al-Dīn al-Samarqandī examined the problem of whether knowledge can be defined and -like Fakhr al-Dīn al-Rāzī (d. 606/1210)- argued that the meaning of knowledge is very clear. In this context, Shams al-Dīn al-Samarqandī, who criticizes the definition of knowledge put forward by the Peripatetic tradition in particular Avicenna (d. 428/1037), determined the ont and non-existent definitions of knowledge and criticized them. This study deals with how the ideal definition theory, which Avicenna founded, was handled by Shams al-Dīn al-Samarqandī and the problem of definition of knowledge according to Shams al-Dīn al-Samarqandī. In addition, with this article, it has been argued that Shams al-Dīn al-Samarqandī did not define knowledge. In this direction, at the beginning of the article, the discussions on the definition of knowledge in the pre-Shams al-Dīn al-Samarqandī kalām tradition and the sides of the issue were examined. Then, in this article, in which the characteristics of the ideal definition according to Shams al-Dīn al-Samarqandī are determined, it is also examined whether he defines knowledge or not. (shrink)

Philosophers and psychologists sometimes categorize emotions like surprise and curiosity as specifically epistemic. Is there some reasonably unified and interesting class of emotions here? If so, what unifies it? This paper proposes and defends an evaluative account of epistemic emotions: what it is to be an epistemic emotion is to have fittingness conditions that distinctively involve some epistemic evaluation. We argue that this view has significant advantages over alternative proposals and is a promising way to identify a limited and interesting (...) class of emotions. (shrink)

Since the publication of Hartry Field’s influential paper “Tarski’s Theory of Truth” there has been an ongoing discussion about the philosophical import of Tarski’s definition. Most of the arguments have aimed to play down that import, starting with that of Field himself. He interpreted Tarski as trying to provide a physicalistic reduction of semantic concepts like truth, and concluded that Tarski had partially failed. Robert Stalnaker and Scott Soames claimed then that Field should have obtained a stronger conclusion, namely (...) that Tarski’s failure in his allegedly intended physicalistic reduction was total. From another front, Hilary Putnam argued for an even more sweeping thesis: “[a]s a philosophical account of truth, Tarski’s theory fails as badly as it is possible for an account to fail.” Scott Soames followed suit also on this count, endorsing Putnam’s argument in section iii of the aforementioned paper; and John Etchemendy used a very similar argument to contend that “a Tarskian definition of truth [...] cannot possibly illuminate the semantic properties of the object language.” The paper argues that these contentions are based on several misunderstandings about the nature of a definition like Tarski’s. Regarding the Putnam-Soames-Etchemendy argument, we must apply a distinction Frege found natural to draw—and is natural to draw anyway—between what he called “constructive” definitions, definitions properly so called, which are mere stipulations, and what he described as “analytic” definitions, definitions which aim to make explicit the meaning of a term already in use. Regarding the Field-Soames-Stalnaker criticism, the paper contends that the true aims of a Tarskian truth definition are perfectly well fulfilled without Field’s amendments. (shrink)

The search for meaningful work has been of interest to researchers from a variety of disciplines for decades and seems to have grown even more recently. Much of the literature assumes that employees share a sense of what is meaningful in work and there isn’t much attention given to how and why meanings might differ. Researchers have not only called for more research studying demographic differences in definitions of meaning :77–90, 2014), but also more research utilizing mixed methods to study (...) psychological concepts like meaningful work Handbook of multimethod measurement in psychology, American Psychological Association, Washington, 2006). This study specifically examines differences across generational cohorts on their prioritization of sources of meaningful work through qualitative, in-depth interviews followed by a more generalizable, quantitative survey. Findings from the qualitative study show that generational cohorts define the meaning in their jobs differently, and they hold negative perceptions about the lack of desire for meaning in each of the other cohorts. Study 2 maps generational cohorts on the comprehensive model of meaningful work designed by Lips-Wiersma and Morris :491–511, 2009) to reveal that although there are some differences in prioritization of sources of meaningful work, all generational cohorts share similar desire to “develop and become themselves” when asked about their definitions of meaningful work. Implications and future research are discussed. (shrink)

This paper side-steps the question of whether ‘the’ concept of sport exists, or can be usefully analysed. Instead, I try to explain the much more modest aim of exhibition-analysis, which is to seek a description of an actually existing example of some concept of sport internal to a normative position. My example is that of Olympic-sport. I try to set out its logically necessary conditions, which of course are conditioned by its context within a theory that emphasises the values of (...) formal competition, citius-altius-fortius, and excellence in contest, as well as rule-based procedural values related to fairness, justice and equality. In so doing, I readily accept that other kinds of sport can be similarly analysed, and I do not press the value claims of Olympic-sport. Instead, I try to show how Olympic-sport, properly construed, can accommodate the concerns of my critics with regard to sport’s play and game-like characteristics. (shrink)

This study discusses the treatise of Jalāl al-Dīn Davvānī (d. 908/1502) named Risāla fī taʻrīf ʻilm. This treatise criticizes a definition of knowledge adopted by some theologians in the late period (mutaʾakhkhirīn). The definition of knowledge at issue consists of three components: Attribution, discernment, no possibility of contradiction. Knowledge is an attribute as a category and with this attribution, a discernment is obtained. As a result of this process knowledge is acquired and there should be no possibility of (...) this knowledge to be inconsistent. Davvānī examines eight possibilities of the definition on knowledge. In each of these eight possibilities a different problems arises. According to Davvānī, the definition mentioned is problematic in all probability. Nonetheless, Davvānī does not propose another definition of knowledge that can replace the definition of knowledge that he criticizes. This article represents the process of reaching the definition of knowledge stated in the history of theological thought. The definitions on knowledge made from the first period (al-mutaqaddimīn) are summarized and the strengths and weaknesses of these definitions are explained. There are two main approaches regarding the nature of knowledge in Islamic thought: According to the first approach pioneered by Fakhr al-Dīn Rāzī (d. 606/1202), absolute knowledge is a priory (badīhī) and undefinable. According to the second one, the nature of absolute knowledge is a posteriori (naẓarī) and definable. The first part of this article includes the definitions and criticisms of knowledge in Islamic thought. The second part discusses the claim of originality. In the second part, Davvānī’s treatise will be evaluated for the first time. According to the conclusion of the treatise, the definition made to find the essence of knowledge is unfounded in all respect. It is important to evaluate the treatise as a reflection of anti-essentialism in the history of Islamic thought. Most contemporary studies do not count this treatise among Davvānī’s works. In the biography book al-Aʿlām written by Khayr al-Dīn al-Ziriklī (d. 1976), Risāla fī taʻrīf ʻilm is counted among the works of Davvānī. In the introduction of more than one manuscript, the work is clearly attributed to Davvānī. As a result of the double-sided research, it has been ensured that the work belongs to Davvānī. However, in other two manuscripts containing the same treatise, the work is shown as belonging to an unknown person named Şāirzāda. But there is no information found about this person. This name seems more like a copyist (mustansıh) than an author. Possibly, such a mistake occurred as a result of confusing the two names. Davvānī’s small volume treatise sheds light on the intellectual atmosphere and level of its period. The definition of knowledge mentioned in the classical theology book of ‘Aḍud al-Dīn al-Ījī (d. 756/1355) called al-Mawāqif is superior to other definitions of knowledge. Instead of this definition of knowledge, which is presented as perfect, Jurjānī (d. 816/1413) preferred the definition of knowledge attributed to al-Māturīdī (d. 333/944) in the Sharḥ al-Mawāqif. This preference has been accepted as an implicit criticism for future generations, including Davvānī. Those who claimed that Jurjānī did not taken a random choice, carried on their criticism by going over the definition. The fine craftsmanship revealed in the treatise reveals that critical thinking is used intensively. The properly understanding of the treatise depends on knowing the science of logic and following it with intense attention. The definition of knowledge is examined from various angles with the help of concepts such as conception, ratification, judgment and contradiction (nakz) of the science of logic. In the science of logic, every layer of knowledge such as certainty, conjecture, imitation, doubt is investigated one by one. In the science of kalām, attention is paid that the ideal level of knowledge is precise. An uncertain knowledge is not considered knowledge according to kalām. Because the main goal of theologians is to build religious beliefs on the obtained certain knowledge. It is not accepted to base knowledge to a probable information on imprecise knowledge. For a knowledge among the knowns to reach the level of certainty, it must be correct and exclude other possibilities. Another condition is required for certainty in the definition of knowledge that Davvānī examines in his treatise is that the opposite is wrong. The fact that a piece of information is considered true depends on the fact that its reverse is false. In this treatise, it is discussed how to look for the contradictions or discrepancy that are wanted to be excluded. Knowledge is inseparable from the human mind, from outside of the world, or from the relationship between the two. (shrink)

In this paper I will offer a novel understanding of a priori knowledge. My claim is that the sharp distinction that is usually made between a priori and a posteriori knowledge is groundless. It will be argued that a plausible understanding of a priori and a posteriori knowledge has to acknowledge that they are in a constant bootstrapping relationship. It is also crucial that we distinguish between a priori propositions that hold in the actual world and merely possible, non-actual a (...) priori propositions, as we will see when considering cases like Euclidean geometry. Furthermore, contrary to what Kripke seems to suggest, a priori knowledge is intimately connected with metaphysical modality, indeed, grounded in it. The task of a priori reasoning, according to this account, is to delimit the space of metaphysically possible worlds in order for us to be able to determine what is actual. (shrink)

This paper aims to uncover where the disagreement between illusionism and anti-illusionism about phenomenal consciousness lies fundamentally. While illusionists claim that phenomenal consciousness does not exist, many philosophers of mind regard illusionism as ridiculous, stating that the existence of phenomenal consciousness cannot be reasonably doubted. The question is, why does such a radical disagreement occur? To address this question, I list various characterisations of the term “phenomenal consciousness”: (1) the what-it-is-like locution, (2) inner ostension, (3) thought experiments such as philosophical (...) zombies, inverted qualia and Mary’s room, (4) scientific knowledge about secondary properties, (5) theoretical properties such as being ineffable and being intrinsic, and (6) appearance/reality collapse. Then I examine whether each characterization provides (i) a dubitable sense of phenomenal consciousness in which the existence of phenomenal consciousness can be reasonably doubted, (ii) an indubitable sense in which its existence cannot be reasonably doubted, or (iii) a gray sense in which it is controversial whether its existence can be reasonably doubted. By doing so, I show that there is no single sense of phenomenal consciousness in which illusionists and anti-illusionists disagree whether the existence of phenomenal consciousness can be reasonably doubted. I conclude that the disagreement between illusionists and anti-illusionists is fundamentally terminological: while illusionists adopt a dubitable sense of phenomenal consciousness, anti-illusionists adopt an indubitable sense of phenomenal consciousness. Because of the extreme vagueness and ambiguity of the term “phenomenal consciousness”, illusionists and anti-illusionists fail to see that they talk about different senses of phenomenal consciousness.

Among the influential contributions of Alfred Tarski to logic and philosophy, and close in importance to his widely applied and discussed definition of truth, one finds his definition of logical consequence for formal languages. Like his definition of truth, Tarski's definition of logical consequence has been widely and fruitfully applied. Unlike the definition of truth, that of logical consequence has been rarely discussed philosophically. The main aim of this dissertation is to offer a thorough discussion (...) of some philosophical issues arising from the neglected definition. ;The point of departure is an interpretative reading of the relevant writings by Tarski. This reading yields historically interesting data that refute other recent readings. It also provides philosophical illumination, by clarifying how Tarski thought that his definition satisfied some pretheoretic desiderata. ;Next it is discussed whether Tarski's definition satisfies other pretheoretic desiderata, not stated by Tarski and in some cases not endorsed by him, but which are desiderata nonetheless from reasonable standpoints. These include the desiderata that all instances of logical consequence in Tarski's defined sense be instances of analytical implication, and that they be instances of valid implication. The conclusion of this part of the dissertation is that, under reasonable assumptions regarding the field of applicability of the definition and the concepts used in it, there are reasons to believe that these desiderata are met, and none to believe they are not. ;Finally, the problem of logical constants is examined. The concept of a "logical constant" is the only concept not taken from logic and mathematics that appears in Tarski's definition. The problem of logical constants is that of replacing the primitive 'logical constant' with a defined, better understood concept, and in a such a way that the resulting defined concept of logical consequence meets the previously discussed desiderata. The main conclusion of this part is that some attempts to do this replace the obscure with the more obscure, while other attempts that seem to be in the right spirit have shortcomings of their own.

Aesthetic theoriesmayclaim universality, but they are normally conditioned by the aesthetic issues and debates of their own times. Plato and Aristo- tle were motivated both to account for the Greek arts of their day and to connect aesthetics to their general metaphysics and theories of value. Closer to our time, asNo¨el Carroll observes, the theories of Clive Bell and R.G. Collingwood can be viewed as “defenses of emerging avant-garde practices— neoimpressionism, on the one hand, and the mod- ernist poetics of (...) Joyce, Stein, and Eliot on the other.”1 Susanne Langer can be read as provid- ing a justification for modern dance, while the ini- tial version of George Dickie’s institutional the- ory “requires something like the presupposition that Dada is a central form of artistic practice” in order to gain intuitive appeal.

Localised configurations of the free electromagnetic field are constructed, possessing properties of massive, spinning, relativistic particles. In an inertial frame, each configuration travels in a straight line at constant speed, less than the speed of lightc, while slowly spreading. It eventually decays into pulses of radiation travelling at speedc. Each configuration has a definite rest mass and internal angular momentum, or spin. Each can be of “electric” or “magnetic” type, according as the radial component of the magnetic or electric field (...) vanishes in the rest frame, and each has an “antiparticle.” Any such configuration, of electric or magnetic type, is characterized in part by a set of labels (κ, ω0, σ,l, m), where ω0 is the mean of the angular frequencies of the plane waves making up the configuration, σ is the variance of those frequencies, κ is a positive constant with dimensions of action, andl, m are angular momentum “quantum numbers” withl a positive integer andm an integer such that ‖m‖≤l. The rest energy of the “particle” is κω0, its spin is κ ‖m‖, and its lifetime is of the order of 1/σ. Its antiparticle has ω0 replaced by −ω0. (shrink)

It is a rather remarkable fact that in most discussions of Aquinas’s ethics, Q. 21 of the De Veritate which deals with Aquinas’s notion of Good, is almost entirely overlooked. For example D. J. O’Connor’s book Aquinas and Natural Law refers only once to the De Veritate and that is not a reference to Q. 21. Even the massive work of Gilson, The Christian Philosophy of St. Thomas Aquinas, in the entire third section which deals with Aquinas’s moral theory has (...) only six references to the De Veritate and again none are to Q. 21. H. J. McCloskey in Meta-Ethics and Normative Ethics, provides what he considers two definitive repudiations of Aquinas’s theory but there is no mention or reference to the De Veritate. There may be a reason for this. Thomists like Gilson may not be attuned to or interested in answering the specific problems which contemporary ethical theorists address themselves to, while ethical theorists like O’Connor seem to depend upon traditional Thomistic accounts to locate the pertinent passages in Aquinas’s ethical writings, accounts which follow the order of one or other of the Summas. Be that as it may, some of the most illuminating sections of Aquinas dealing with ethical-theoretical issues are to be found in Question 21 of the De Veritate, for in this question is found a definition of the good as well as explanations of this definition. Consider the following passages where Aquinas lists what seem to be necessary conditions for calling something good. (shrink)

This paper argues that Cicero develops a new view of the state as a partnership in his work De republica. Like any other partnership, the Roman state is upheld by the agreement of its members and an allocation of rewards that is proportionate to the contributions. Cicero sketches an outline of this view in his definition of this state. By focusing on how Cicero uses the definition in the construction of his argument, the paper attempts to uncover a (...) detailed view of the state as a partnership. The ancestral Roman constitution, Cicero argues, surpasses all other constitutions in offering the best division of contributions and rewards. Although the state is held together by the agreement of the whole people, there is an enormous disparity in the assessment of contributions and rewards among different social groups. (shrink)

In a previous article, I attempted to assess the likely impact of the most prominent versions of the therapeutic misconception (TM) on research subjects’ informed consent. I concluded that the TM is not nearly as significant a concern as is commonly thought, and that focusing on it is more likely to undermine than promote research subjects’ informed consent.A recent commentary rejects these conclusions, as least as they pertain to the “consensus” definition of the TM. The authors of the commentary (...) argue that work on the TM remains central to ensuring the appropriateness of research subjects’ consent and, by implication, the ethical acceptability of clinical research.The present work evaluates the arguments offered in support of these claims. This analysis reveals that the authors offer few substantive responses to my arguments, and the responses they do offer fail to undermine my prior conclusions. Furthermore, consideration of an additional issue—the emergence of learning healthcare systems—suggests that the TM is likely to be even less significant in the future, hence, focusing on it may be even more problematic than I argued previously.

Since it has generally been accepted that to Spinoza attributes are real features of substance, the interpretation of his attribute definition has become a notorious problem. The reason is that interpreters have failed to see that the definition formulates a purely epistemological account of the state of affairs. The article presents and justifies such an interpretation. It will be shown that the definition in spite of its epistemological character implies a real ontological definition, which specifies the (...) critical features of an attribute. As to the reason why Spinoza has stated the definition in an ‘indirect way’, it is shown that it is likely that he has done so in order to have a more efficient, a more unambiguous and a more elegant definition. The relevance of the new interpretation is not only that it provides us with an interpretable, transparent attribute definition, but it also contributes to the establishment of a coherent picture of Spinoza’s metaphysics around this definition.

The International Holocaust Remembrance Alliance (IHRA) developed a ‘Working Definition of Antisemitism’ in 2016. Whilst the definition has received a significant amount of media attention, we are not aware of any comprehensive philosophical analysis. This article analyses this definition. We conclude that the definition and its list of examples ought to be rejected. The urgency to do so stems from the fact that pro-Israel activists can and have mobilised the IHRA document for political goals unrelated to (...) tackling antisemitism, notably to stigmatise and silence critics of the Israeli government. This causes widespread self-censorship, has an adverse impact on freedom of speech, and impedes action against the unjust treatment of Palestinians. We also identify intrinsic problems in the way the definition refers to criticism of Israel similar ‘to that leveled against any other country’, ambiguous wording about ‘the power of Jews as a collective’, lack of clarity as to the Jewish people’s ‘right to self-determination’, and its denial of obvious racism. We consider alternative definitions and prefer one like the Oxford English Dictionary (OED) definition, ‘hostility to or prejudice against Jews’, with the addition of the words ‘as Jews’. We recognise that the Jerusalem Declaration on Antisemitism (JDA) can play a useful purpose in illustrating the shortcomings of the IHRA definition. However, we do not advocate promoting it as the prime international definition. Indeed, we question the efficacy of using complex new definitions to combat racism against Jews or other groups, and instead advocate combatting it through collective action across societies.

In this report we focus on the definition of autonomous weapons systems (AWS). We provide a comparative analysis of existing official definitions of AWS as provided by States and international organisations, like ICRC and NATO. The analysis highlights that the definitions draw focus on different aspects of AWS and hence lead to different approaches to address the ethical and legal problems of these weapons systems. This approach is detrimental both in terms of fostering an understanding of AWS and in (...) facilitating agreement around conditions of deployment and regulations of their use and, indeed, whether AWS are to be used at all. We draw from the comparative analysis to identify essential aspects of AWS and then offer a definition that provides a value-neutral ground to address the relevant ethical and legal problems. In particular, we identify four key aspects—autonomy; adapting capabilities of AWS; human control; and purpose of use—as the essential factors to define AWS and which are key when considering the related ethical and legal implications.

It has been claimed that the prototype theory of concepts supports two controversial claims in the philosophy of art: that art cannot be defined, and that the possession of a certain sort of historical narrative is a sufficient but not necessary means of determining the art status of contested works. It is argued here that two sorts of considerations undermine the thesis that prototype theory offers significant support to anti-definitionism and historical narrativism. First, there is reason to think that prototype (...) theory is as a psychological theory not the sort of view that can support philosophical theories like anti-definitionism and historical narrativism. Second, well-known objections and theoretical alternatives to prototype theory theory raise serious questions about that theory’s own credentials. (shrink)

Popper’s original definition of verisimilitude in terms of comparisons of truth content and falsity content has known counter-examples. More complicated approaches have met with mixed success. This paper uses a new account of logical content to develop a definition of verisimilitude that is close to Popper’s original account. It is claimed that Popper’s mistake was to couch his account of truth and falsity content in terms of true and false consequences. Comparison to a similar approach by (...) Schurz and Wiengartner show certain advantages of this new approach. (shrink)

There is no satisfactory account for the general phenomenon of confabulation, for the following reasons: (1) confabulation occurs in a number of pathological and non-pathological conditions; (2) impairments giving rise to confabulation are likely to have different neural bases; and (3) there is no unique theory explaining the aetiology of confabulations. An epistemic approach to defining confabulation could solve all of these issues, by focusing on the surface features of the phenomenon. However, existing epistemic accounts are unable to offer sufficient (...) conditions for confabulation and tend to emphasise only its epistemic disadvantages. In this paper, we argue that a satisfactory epistemic account of confabulation should also acknowledge those features which are (potentially) epistemically advantageous. For example, confabulation may allow subjects to exercise some control over their own cognitive life which is instrumental to the construction or preservation of their sense of self. (shrink)

The current investigation assessed linguistic and narrative abilities in a cohort of children with Autism Spectrum Disorder (ASD). The linguistic assessment was performed with both traditional tests and a multilevel procedure for discourse analysis. The results showed difficulties at different stages of message planning, organization, and microlinguistic processing (i.e., lexical selection and grammatical processing). Their macrolinguistic impairments were likely related to more general difficulties in the prelinguistic conceptual phase of message planning and mental model generation. Such weaknesses included a difficulty (...) in the non-verbal conceptualization of the story and the generation of an internal representation of the addressee’s mental model. (shrink)

This paper defines in a formal and computational way the notion of ‘consilience’, a term introduced by Whewell in 1847 for the evaluation of scientific theories. Informally, as has been used to date, a model or theory is ‘consilient’ if it is predictive, explanatory and unifies the evide-nce. Centred in a constructive framework, where new terms can be intro-duced, we essay a formalisation of the idea of unification based on the avoidance of ‘sepa-ration’. However, it is soon manifest that this (...) classical approach is vulnerable to the introduction of fantastic concepts to unify disparate sub-theories. Our second approach is constructed by using a detailed evaluation of the relationship between the theory and the evid-ence by means of reinforcement propagation. With the use of reinfor-cement, fantastic concepts can be better detected and the role of con-silience for theory construction and revision can be specialised for dif-ferent inference mechanisms like explanatory induction, abduction, deduc-tion and analogy.

I present a new definition of verisimilitude, framed in terms of causes. Roughly speaking, according to it a scientific model is approximately true if it captures accurately the strengths of the causes present in any given situation. Against much of the literature, I argue that any satisfactory account of verisimilitude must inevitably restrict its judgments to context-specific models rather than general theories. We may still endorse—and only need—a relativized notion of scientific progress, understood now not as global (...) advance but rather as the mastering of particular problems. This also sheds new light on longstanding difficulties surrounding language-dependence and models committed to false ontologies. (shrink)

In this contribution, I deal firstly with the problem of whether ‘religion’ can actually be defined. My answer is twofold. Firstly, that such a definition must indeed be deemed to be extremely un-like¬ly, if not downright impossible. Secondly, however, that definition also has more modest uses which may turn definitions of religion, that have shed this universalist ambition, into quite useful tools in the academic study of religions. In the second section, I shall address the question of why, (...) if a definition of religion turned out to be merely a useful research tool, one should bother to define ‘religion’ at all. My answer will be that one may indeed well dispense with it, but that, despite its very modest usefulness, it would still be unwise to do so. In my third section, I shall discuss these modest uses of definitions of religion, as well as their strategic implications. In the fourth and last section, I shall discuss the operational, or instrumental, definition of ‘religion’ which I have developed for my particular line of studies as an illustration of the pur¬poses which a definition of religion may serve in the academic study of religions.

A metric approach to Popper's verisimilitude question is proposed which is related to point-free geometry. Indeed, we define the theory of approximate metric spaces whose primitive notions are regions, inclusion relation, minimum distance, and maximum distance between regions. Then, we show that the class of possible scientific theories has the structure of an approximate metric space. So, we can define the verisimilitude of a theory as a function of its (approximate) distance from the truth. This avoids some of (...) the difficulties arising from the known definitions of verisimilitude. (shrink)

This paper focuses on the philosophical-ethical foundations of Constantine’s definition of philosophy, as well as its anthropological and axiological aspects. The focus is placed on the relationship between definitions of philosophy postulated by Constantine the Philosopher and John of Damascus, the latter of which traces the six classical definitions systematized by Platonic commentators. Byzantine thinkers proposed a method of unifying both the theoretical and practical aspects of ancient philosophy with a Christian way of life by interpreting the classical definitions (...) of philosophy and dividing it into theoretical and practical parts, the latter including ethics. Constantine understood philosophy in the sense of the second (knowledge of things Divine and human) and the fourth (becoming like God) meanings of earlier definitions, with the addition of the Christian sense of acting in accordance with the image of God. In addition to these gnosiological and anthropological aspects, the paper also observes the axiological aspect of Constantine’s definition of philosophy, which appears to be a foundation for exploring human behaviour as in compliance with Christian laws encouraging changes in ethical principles so as to follow a new code of ethics, through which new values were presented to the Slavs. (shrink)

Like other fundamental experiences, the phenomenal qualities of pain seem to defy description. But, unlike these experiences, it is difficult to define pain in terms of a consistent relationship with the extra-mental world. The IASP's solution is to qualify an imprecise characterization of pain's phenomenal qualities through an association with tissue damage and an ability to recognize pain sensation. In this paper I will argue that the IASP's definition lacks the clarity and coherence necessary to provide an adequate (...) class='Hi'>definition of pain. I begin by setting out the difficulties of defining pain. I then describe the IASP's solution and provide a detailed criticism of their approach. I also discuss inconsistencies evident in their wider taxonomy. In the final section I argue that pain can be objectively grounded by reference to pain's evolutionary role and suggest an alternative definition. (shrink)
