This paper calculates, in a precise way, the complexity of the index sets for three classes of computable structures: the class $K_{\omega _{1}^{\mathit{CK}}}$ of structures of Scott rank $\omega _{1}^{\mathit{CK}}$ , the class $K_{\omega _{1}^{\mathit{CK}}+1}$ of structures of Scott rank $\omega _{1}^{\mathit{CK}}+1$ , and the class K of all structures of non-computable Scott rank. We show that I(K) is m-complete $\Sigma _{1}^{1},\,I(K_{\omega _{1}^{\mathit{CK}}})$ is m-complete $\Pi _{2}^{0}$ relative to Kleen's O, and $I(K_{\omega _{1}^{\mathit{CK}}+1})$ is m-complete $\Sigma _{2}^{0}$ relative to O.

The concept of an appearance is bona fide and rule‐governed. It is such that appearances can be shared, which suggests that a visual appearance is a complex universal, compounded out of colour and spatial appearance. The only appearance material objects have is their look, because uniquely in the case of sight when the Attention lands upon its colour it lands upon the object, and it lands upon the object through landing upon its secondary quality. We experience the visual appearance when (...) we perceive the bearer to be endowed with those visible qualities that visually individuate it for us. Now the primary appearance in Physical Reality is the look of a material object, a ‘look in the round’, upon which aspect‐appearance is dependent. The relation between the two is charted, together with the vital role of the understanding in experiencing ‘looks in the round’, an experience that depends upon knowledge of the objective physical situation in which it occurs. Finally, the criteria of visibility are spelt out. (shrink)

Rationality of state is essential to consciousness, and depends both on self‐knowledge and on mental activeness—and above all upon the mental activity of thinking. What contribution does the overall activeness of the stream of consciousness make to the obtaining of consciousness? It firstly contributes to the epistemological and perceptual function, through ordering perceptual process. But it secondly conditions the intelligibility of the stream of consciousness of the conscious. The least apparently active experiences of the conscious, such as daydreaming, are shown (...) to be intentionally active, along with the others. This activeness makes possible rationality and explanatorial pellucidity in the development of that ‘stream’, which would otherwise be absent, because of the close link between activeness and rationality. This internal intelligibility has epistemological repercussions, for it is a necessary condition for making sense of the outer phenomenal world. (shrink)

The stream of consciousness of the waking conscious manifests both meaningfulness and interiority as the dream does not. The variety of meaning involved is spelt out. It emerges that it is a derivative of the overall mental activeness of consciousness together with the fact that the activeness pre‐eminently includes the thinking process. This is the one active experiential line that carries its own rationale, for thinking is a mental willing, which par excellence knows where it is going, indeed is the (...) meaning‐giver par excellence in the mind. The nature of thinking is investigated, including the rationale of its close link with the use of language. Thinking is an active process of engendering phenomena in one's understanding, whose object is a changing entity expressed in the symbolism that encapsulates thought. It lies at the heart of consciousness, being the custodial agency responsible for the continuing state of rationality necessary for the state, and is coincident with the interiority of that state.

Proprioception is true perceiving. It and touch form a closely linked mutually dependent yet diverse pair. The puzzle whereby the demands upon the Attention of proprioception are no distraction in instrumental action is resoluble through the fact that the internal active content within an instrumental deed is a harmonious hierarchy. The ‘long‐term body image’ is a causally posited something whose content encompasses body shape, which is a necessary but insufficient condition of proprioception of body shape and posture. It is distinct (...) from the ‘short‐term body image’, which designates the internal content of the proprioceptive perception of the body at any moment. The main philosophical problem consists in assembling a bona fide veridical concept of the long‐term image. Reasons for positing it begin with the common content in the short‐term images over lengthy periods. But they must be supplemented by the fact that bodily sensations do not represent body shape, being already dependent on body‐awareness for both individuation and position. Only through hypothesizing a long‐term image can one make sense of proprioception. Reasons are given for believing the body image is a dispositional psychological phenomenon, it is one and the same when explaining proprioception and sensation‐location, it is an empirical postulate, and even though it falls short of being an a priori necessity, it is as deeply embedded in animal existence as proprioception.

What is implicit in a typically human perception of a material object? First, perceivability is a contingent property of its bearer, relative to perceiver and conditions. Typically, human perception is special in involving the use of concepts and an awareness of object‐structures. When we visually recognize a material object, an almost limitless array of properties and procedures are by implication condensed into an instant: one entertains multiple beliefs, and posits at a distance, multiple properties. Then the experiential integration of the (...) almost limitless visual evidence of a material object is dubbed ‘constituting the material object out of experience’. Central concepts in doing so are those of side, outside, surface, interior, and part. The most important of these experiential syntheses is the spatial, whose unit is the 3D‐seeing of object‐sides, a concept that depends upon those of 2D/3D and 2D/2D seeing. Two vitally important elements in this procedure are, first, the work of the understanding, second, an awareness of the objective physical situation of perceiver and object. (shrink)

Self‐awareness—knowledge of self and of one's mental states—is of central importance in ensuring the properties constitutive of consciousness in rational beings. A modified Cartesian thesis is defended: that a well‐formed state of self‐conscious wakefulness is such that the present contents of that mind must be insightfully given to its owner. This is demonstrated through investigating four different states in which insight is diminished and consciousness absent or impaired: sleep, trance, intoxication, and psychosis. These states are analytically explored, and the thesis (...) proven in each case. It emerges that the very items that constitute consciousness in unthinking animals, do the same in thinking animals, only in a more developed form. The differentia of the state of self‐conscious wakefulness is analysed into the co‐presence of a syndrome of mutually necessitating properties : self‐knowledge, rationality, freedom, thinking, etc. When this syndrome is conjoined with the availability of the perceptual attention, together with experience, the state is fully constituted. This is the answer to the fundamental question: what is consciousness? (shrink)

Secondary qualities are essential to sight, hearing, smell, and taste, and correspond to the sensations definitive of each sense. They are relative, first to which beings they appear to, secondly to the conditions under which they do so. Dispositionist analyses are examined, along with materialist, and rejected: the former because colour is predicable of after‐images, the latter because a disjunct of material properties in principle ‘found’ any secondary quality. While attributions to physical objects are relative, attribution to sensations are absolute: (...) sensations of red are absolutely, intrinsically, essentially red. ‘Red’ names the look predicable necessarily of the sensation of red and contingently and derivatively of much else. What is of central importance to the secondary quality, indeed the rationale behind the very concept, is that it is the only psychological phenomenon that can be an immediate material or external object of noticing. From this unique property, compounded with the psycho‐physical nomic situation governing its objectification, flows the special utility of the secondary quality. Namely, to take its place as material object for the Attention in an experience in which it simultaneously qualifies a whole string of causally interrelated items: sensation, light, surface, side, and object.

In perception, objects come to the attention. Accordingly, one might come to believe that ‘The Attention’ names the capacity to harbour events of the specific idiosyncratic type, noticing. In fact it signifies an experiential mental space to which objects can come in perception and, which can contain experiences. After all, many mental phenomena other than perception require awareness if they are to so much as exist, e.g. emotion and thought, thanks to being experiences. That experiential space is of limited extent, (...) for at any moment the mind can experience so much and no more. Indeed, the space is no more than the existence of such a limit, and has no autonomous existence other than the fact of that limit, and it is a dangerous illusion to hypostatize the limit as a real space, leading one to misunderstand what it is to experience an experience. Then there is reason for supposing that the experiences of the moment constitute a system. This circle or centre of awareness is the Attention. And it is to this Attention that perceived existents come—as object. This happens when a noticing or perceiving occurs. (shrink)

The definition of perception is defended by piecemeal assembling of the concept of perception. We begin with the assumption that some event is an intentionally directed experience; add that it is of a type that aspires to ‘success’‐status, as seem‐see and try‐act aspire to status see and act ; and add that the object actually exists, and that the ‘aspiration’ is successful. Now this complex property fits both action and perception. Then to define action we have the need of a (...) further and indefinable concept, that of will, whereas to define perception we have all the conceptual material we need, for we need no more than the concepts, experience, and object. Perception is unique in being the only experience that finds its identity under the concept of experience, for it is merely awareness or experience taking an extensional object. Then since consciousness and experience are universal to any account of mind, perception likewise must have a position of centrality in the mind. It is an a priori‐given a priori‐definable concept, built out of a priori‐given concepts.. (shrink)

The topic is the state of wakeful consciousness. Of what kind is this state? It is the pre‐eminent and ‘founding father’–species of the genus, state of consciousness, all other species being privative derivatives from the original. Consciousness, which is endowed with necessary properties, is constituted‐by rather than the cause‐of its necessary properties. These last include the negative properties of lacking an intentional object, of not being the perception of anything, and of being inexperiencable, together with the following positive properties: encompassing (...) experience, accessibility of the perceptual attention, suitable mode of belief‐formation, obligatory mental activeness together with immediate acquaintance with past and future, and conditional availability of the bodily will. This is a characterization of the consciousness of both rational and non‐rational animals. (shrink)

Modern ethico-philosophical literature treats spirituality as a value characteristic of moral consciousness, although spirituality is a complex and multifaceted phenomenon. Therefore, this one-sided approach is wrong. In considering this problem, two approaches were identified: theological and purely philosophical. In philosophical thought, the understanding of spirituality as a qualitative characteristic of consciousness, actions and actions of a person, its ability to do good for the benefit of society, its people, and the state, was affirmed. And if so, any person, regardless of (...) his or her outlook, is spiritual. (shrink)

Are new democracies with divided government and volatile parties politically ill fated? The literature suggests so, but cases of emergent democracies such as Taiwan and Brazil that face both conditions defy the prediction. This paper explains why: party volatility follows from pursuing distinct executive and legislature agendas under divided government; the political ambition that underlies these conditions sustains democratic and even political performance. We evaluate the argument through government spending in Taiwan. The results corroborate our expectations: they show more parties (...) composing the legislature as government spending favors an executive agenda and neglects a legislative welfare-spending agenda. The findings make three contributions to the literature: first, they reveal a political divide between executive and legislature rather than ideological parties to undercut concerns regarding performance. Second, they demonstrate that the strategic use of government spending to institutionalize party development along an executive agenda fuels party fragmentation. Third, they show that legislators split, switch, or create alternative routes to office in reaction to strategic spending to underscore that ambition underlies party volatility and divided government.

Towards Justice and Virtue challenges the rivalry between those who advocate only abstract, universal principles of justice and those who commend only the particularities of virtuous lives. Onora O'Neill traces this impasse to defects in underlying conceptions of reasoning about action. She proposes and vindicates a modest account of ethical reasoning and a reasoned way of answering the question 'who counts?', then uses these to construct linked accounts of principles by which we can move towards just institutions and virtuous lives.

This study is aimed at evaluating the influence of the god of iron on ironworking communities in Ǹsúkkā cultural area. In the study area, the Supreme God – Chúkwú Òkìkè, Chínēkè or Chúkwú Ábíàmà is believed to control the affairs of humanity. He is worshipped through intermediaries such as Ányánwù [Sun God], Àmádíòhà, Áhàjīōkù [fertility goddess], Àlà [earth goddess] and the god of iron, which is called by different names in the study area such as Ékwéñsū-Úzù, Òkóró-Údùmè, Chíkèrè Àgùrù and (...) Áshéné. But, how effective is the god of iron in the study area? To provide answers to this question, ethnographic research method, involving in-depth structured interviews, field observation and photographic documentations, was used to gather data on the subject matter while data collected were analysed descriptively. This article is of the view that the influence of the god of iron in the study area is whittling down as a result of Westernisation and Christianity.Contribution: The study indicates an increasing resistance to the Euro-centrism, which has suppressed beliefs in the god of iron and the associated practices.

James O. Young seeks to explain why we value music so highly. He draws on the latest psychological research to argue that music is expressive of emotion by resembling human expressive behaviour. The representation of emotion in music gives it the capacity to provide psychological insight--and it is this which explains a good deal of its value.

In this article, the author analyzes the concept of religious foundations of culture and power as a problem of Russian political consciousness. The paper reveals the patterns of interaction between the religious and political traditions of the Russian Empire in the early 20th century. The author provides Bargradsky project case as a unique example of such influence, identifying its mean in the later Russian Empire’s political history. Philosophical-political case that is analyzed in the article makes it possible to trace the (...) inner links between religious attitudes and political imagination of Russian monarchical circles and to identify the peculiarities of religious and political self-awareness of Russian power, its mechanisms for the selecting the ideas, symbols, images of the national political, religious and artistic culture in the last period of the Russian Empire. From our point of view, it would be most effective to combine the cultural-historical and the philosophical and historical approaches both in the reconstruction of Bargradsky project and in studies of Russian political culture. The article examines both the political conditions of activities and spiritual-cultural goals of Bargradsky Committee on Bargradsky project in Italian Bari as well as in Saint Petersburg in the 1910s. The author discusses the religious concept of Russian political culture, applying philosophical-historical method for the analyses Bargradsky Committee activity and its attempt to slow down the degradation of the Russian autocracy. The major emphasis is placed on the political and philosophical way of analysis as well as on the possibility of introducing the results of philosophical-historical research into current debates on the issue of alternatives to Russian history.

We define in precise terms the basic properties that an ‘ideal propositional paraconsistent logic’ is expected to have, and investigate the relations between them. This leads to a precise characterization of ideal propositional paraconsistent logics. We show that every three-valued paraconsistent logic which is contained in classical logic, and has a proper implication connective, is ideal. Then we show that for every n > 2 there exists an extensive family of ideal n -valued logics, each one of which is not (...) equivalent to any k -valued logic with k < n. (shrink)

This paper rejoins the debate surrounding Thomas Tymockzko’s paper on the surveyability of proof, first published in the Journal of Philosophy, and makes the claim that by attending to certain broad features of modern conceptions of proof we may understand ways in which the debate surrounding the surveyability of proof has heretofore remained unduly circumscribed. Motivated by these historical reflections, I suggest a distinction between local and global surveyability which I believe has the promise to open up significant new advances (...) in the philosophy of mathematics.

This introduction to Epicureanism offers students and general readers a clear exposition of the central tenets of Epicurean philosophy, one of the dominant schools of the Hellenistic period. Founded by Epicurus of Samos (c. 341–270 BCE), it held that for a human being the greatest good was to attain tranquility, free from fear and bodily pain, by seeking to understand the workings of the world and the limits of our desires. Tim O’Keefe provides an extended exegesis of the arguments that (...) support Epicurean philosophical positions, analyzing both their strengths and their weaknesses while showing how the different areas of Epicurean inquiry come together to make a whole.

Economic liberty is best understood in opposition to economic domination. This article develops a radical republican conception of such domination. In particular, I argue that radical republicanism provides a more satisfactory account of individual economic freedom than the market-friendly liberties of working, transacting, holding, and using championed by Nickel and Tomasi. So too, it avoids the pitfalls of other conceptions of economic liberty which emphasize real freedom, alternatives to immiserating work, or unalienated labor. The resulting theory holds that economic domination (...) occurs when someone’s access to civic capabilities is contingent on the arbitrary economic power of others. Socialist institutions—suitably configured—can deliver on this individual economic freedom, allowing the dominating power of proprietors, shareholders, landlords, and managers to be kept in check, and providing an unconditional minimum that allows individual citizens to be less beholden to others in meeting many of their most fundamental civic needs. Thus, I conclude that socialism can be championed as a politics of individual economic liberty. (shrink)

Almost all of us would agree that the experience of art is deeply rewarding. Why this is the case remains a puzzle; nor does it explain why many of us find works of art much more important than other sources of pleasure. Art and Knowledge argues that the experience of art is so rewarding because it can be an important source of knowledge about ourselves and our relation to each other and to the world. The view that art is a (...) source of knowledge can be traced as far back as Aristotle and Horace. Artists as various as Tasso, Sidney, Henry James and Mendelssohn have believed that art contributes to knowledge. As attractive as this view may be, it has never been satisfactorily defended, either by artists or philosophers. Art and Knowledge reflects on the essence of art and argues that it ought to provide insight as well as pleasure. It argues that all the arts, including music, are importantly representational. This kind of representation is fundamentally different from that found in the sciences, but it can provide insights as important and profound as available from the sciences. Once we recognise that works of art can contribute to knowledge we can avoid thorough relativism about aesthetic value and we can be in a position to evaluate the avant-garde art of the past 100 years. Art and Knowledge is an exceptionally clear and interesting, as well as controversial, exploration of what art is and why it is valuable. It will be of interest to all philosophers of art, artists and art critics. (shrink)

Who ought to do what, and for whom, if global justice is to progress? In this collection of essays on justice beyond borders, Onora O'Neill criticises theoretical approaches that concentrate on rights, yet ignore both the obligations that must be met to realise those rights, and the capacities needed by those who shoulder these obligations. She notes that states are profoundly anti-cosmopolitan institutions, and that even those committed to justice and universal rights often lack the competence and the will to (...) secure them, let alone to secure them beyond their borders. She argues for a wider conception of global justice, in which obligations may be held either by states or by competent non-state actors, and in which borders themselves must meet standards of justice. This rich and wide-ranging collection will appeal to a broad array of academic researchers and advanced students of political philosophy, political theory, international relations and philosophy of law.

El presente artículo corresponde a un análisis sobre la existencia del hombre actual inmerso en el capitalismo y su relación con el sufrimiento humano, modo de vida que él mismo ha ayudado a construir y mantener en procura de un hedonismo que le hace olvidarse como sujeto doliente. Dada su responsabilidad en el devenir de este sistema económico social, el planteamiento que aquí se expone, invita a repensar al hombre en la búsqueda aproximada por la verdad de sí mismo y (...) de su ser-en-el-mundo al modo heideggeriano. Es así como este escrito procura dejar en claro cuál es el estatuto que en la actualidad ocupa el hombre en el mundo capitalista, espacio en el que se requiere responsabilizarse por sí mismo y por los otros. Para ello, se acude a la biografía de Vincent van Gogh como ejemplo de un hombre que decidió vivir de acuerdo con su pasión, en la sencillez y lejos de todo sistema capitalista; que se atrevió a mirar de frente el dolor y a encontrar en su sufrimiento y el de los otros una verdad. Un hombre que logró captar el realismo de la pobreza y de la bondad humana y que por ello pagó y resistió el precio de la diferencia, que por estar ajeno a todo capitalismo fue catalogado con el rótulo de la “locura” en cuya esencia se encubrió un gran saber.

The analysis of historical literature allows to consider profoundly the development of national culture and science of the 18th-first half of the 20th centuries and the formation and change of different historical concepts. With the analysis of historical periods that are highlighted in the research, general trends in the changing of paradigms about Russian historical development were concluded, which were translated to mass historical consciousness from the beginning of the 18th century up to 1917. The periods were closely connected with (...) the specific political, historical and economic changes in Russian Empire and with the dominance of certain textbooks during this time. The books were selected because of a number of factors: their inclusion to the school curriculum, the number of publications, the equal number of textbooks devoted to different historical periods. For the analysis were used 19 textbooks, schoolbooks for different courses of secondary schools and primary schools. All the sources of educational literature were grouped into two concepts - officially-state and the liberal. Each publication was highlighted the dominant concept as a base for the whole textbook. There is also a characteristic of the concepts that are presented chronologically. The analysis represents school history books as an important source for the formation of state policy in the representing of Russian history, and, that is more important, for creation of the concept of the state of Russian history.

In this book, Tim O'Keefe reconstructs the theory of freedom of the ancient Greek philosopher Epicurus (341-271/0 BCE). Epicurus' theory has attracted much interest, but our attempts to understand it have been hampered by reading it anachronistically as the discovery of the modern problem of free will and determinism. O'Keefe argues that the sort of freedom which Epicurus wanted to preserve is significantly different from the 'free will' which philosophers debate today, and that in its emphasis on rational action it (...) has much closer affinities with Aristotle's thought than with current preoccupations. His original and provocative book will be of interest to a wide range of readers in Hellenistic philosophy. (shrink)

Animals, Equality and Democracy examines the structure of animal protection legislation and finds that it is deeply inequitable, with a tendency to favor those animals the community is most likely to see and engage with. Siobhan O'Sullivan argues that these inequities violate fundamental principle of justice and transparency.
