The New Age philosopher, Rudolf Steiner (1861-1925), was the most prolific and arguably the most influential philosopher of his era. He assembled a substantial library, of approximately 9,000 items, which has been preserved intact since his death. Most of Rudolf Steiner’s books are in German, his native language however there are books in other languages, including English, French, Italian, Swedish, Sanskrit and Latin. There are more books in English than in any other foreign language. Steiner esteemed English as “a (...) universal world language”. The present paper identifies 327 books in English in Rudolf Steiner’s personal library. Fifty percent of the English-language books identified are on Theosophy (n=164). Rudolf Steiner was the General Secretary of the German branch of the Theosophy Society from 1902, and he hived off his own Anthroposophy Society in 1912. The present study reveals that Steiner maintained his interest in Theosophy throughout his life as he stayed up to date with the proliferating portfolio of Theosophy publications. The publication dates of Steiner’s Theosophy collection range from 1877 to 1923. The leading exponents of Theosophy in his day are well represented in Steiner’s collection, including Annie Besant (n=61), Charles Leadbeater (n=13), William Westcott (n=13) and Helena Blavatsky (n=10). Of the other 50% of the Anglo-books identified, 20% are in the category of Religion (n=67), 10% are Social Science (n=33), 6% are Philosophy (n=21), 4% are Science (n=13), and 3% each are Anthroposophy (n=11), History (n=9) and Arts (n=9). The publication dates of Steiner’s Anglo-books span the period 1659 to 1925. This demonstrates that Steiner was acquiring Anglo-books right to the end of his life. The Steiner library throws light on the development of the thoughts of this remarkable individual and the present paper reveals Steiner’s engagement throughout his life with the world of Anglo-publishing and thought.

We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We provide a case study for the application of the methods to (...) the problem of identifying and extracting arguments about anthropomorphism during a critical period in the development of comparative psychology. We show how a combination of classification systems and mixed-membership models trained over large digital libraries can inform resource discovery in this domain. Through a novel approach of “drill-down” topic modeling—simultaneously reducing both the size of the corpus and the unit of analysis—we are able to reduce a large collection of fulltext volumes to a much smaller set of pages within six focal volumes containing arguments of interest to historians and philosophers of comparative psychology. The volumes identified in this way did not appear among the first ten results of the keyword search in the HathiTrust digital library and the pages bear the kind of “close reading” needed to generate original interpretations that is the heart of scholarly work in the humanities. Zooming back out, we provide a way to place the books onto a map of science originally constructed from very different data and for different purposes. The multilevel approach advances understanding of the intellectual and societal contexts in which writings are interpreted. (shrink)

The literature is predominated by studies seeking to clarify the extent of the availability, functionality, accessibility and/or utilisation of library materials in schools at various levels. The extent of principals' management of library resources and their contribution to the lesson preparation activities of teachers seems to have been under-researched. In bridging the gap, the current study was designed to assess the extent and contribution of principals’ management of library resources to teachers’ lesson preparation practices. Six specific objectives (...) were of interest to the researchers. The quantitative research method, following the ex-post facto research design, was adopted. The stratified proportional random sampling technique was used to choose a sample of 743 respondents from a population of 1,857 secondary school teachers in Ikom Education Zone, Cross River State, Nigeria. An instrument named "Management of Library Resources and Teachers' Lesson Preparation Questionnaire" (MLRTLPQ) was used to gather data. The quantitative content validity method was used to assess the degree to which the items in the instrument were clear, relevant, and represented a wide range of the anticipated content based on the views of domain experts. One sample t-test and hierarchical regression analyses were used for data analyses. Four stepwise hierarchical linear models were specified and fitted accordingly. It was found that teachers’ lesson preparation practice is significantly low generally; there is a significantly low extent in principals’ management of textual, auditory, visual and audio-visual library resources; there is a significant composite contribution of principals’ management of library resources on teachers’ lesson preparation practices in public secondary schools in model 3 and model 4. Based on these findings, practical implications are discussed, with recommendations made for a better library management practice in secondary schools for quality lesson preparation practices.

Philosophers of literature do not take much of an interest in autobiography.1 In one sense this is not surprising. As a certain prejudice has it, autobiography is, along with biography, the preferred reading of people who do not really like to read. The very words can conjure up images of what one finds on bookshelves in Florida retirement communities and in underfunded public libraries, books with titles like Under the Rainbow: The Real Liza Minnelli or Me: Stories of My Life (...) (Katharine Hepburn).2 Hardly rousing material, at least from the philosophical point of view. But on a moment’s reflection, it becomes clear that the initial prejudice is unfounded. Never mind the fact that there are obviously .. (shrink)

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

A preponderance of empirical research in higher education exists on the use of electronic resources to promote university education and learning. This suggests that this area of research has attracted significant interest worldwide. However, there seems to be inadequate information on the association between specific electronic infrastructures, how they are utilized for learning, and their effects on students’ learning effectiveness in higher institutions in Nigeria. This research draws on previous studies and seeks to establish how different electronic resources are used (...) in universities and how they impact students’ learning effectiveness. Using a descriptive survey design, this survey examined 1,452 participants (undergraduates and postgraduates) from Nigerian universities. The data were analyzed using mean and standard deviation, while a Polytomous Logistic Regression Model was used in testing the hypothesis formulated. Findings showed that the degree of the use of digital infrastructures in universities is low. The extent of learning effectiveness among students in universities is also low. The usage of e-infrastructures (such as e-learning, e-communication, and e-library tools) significantly predicted students’ levels of learning effectiveness. Based on these results, conclusions and relevant theoretical and practical implications are discussed for policy reforms in education and e-learning. This study faces a limitation arising from the small number of universities studied. However, it is suggested that future related studies extend their focus beyond the context of Nigeria. (shrink)

From a modernist perspective, it may be difficult to ascribe graphics to any form of traditional African art. This could be due to the embrace of western values by Africans, and of modernity on the one hand, and the overwhelming negative influence of westernization on the diverse African cultural practices, on the other hand. However, many elements of the traditional art forms are imbued with icons and symbols which expressions may be viewed as graphical in nature. This paper looks into (...) the dynamics of graphics in the art of the traditional Ibibio society of Nigeria and attempts to appraise form and content. It is aimed at investigating the various symbolic applications in Ibibio traditional art forms and to establish the degree of graphics inter face with these art forms. The paper expounds the term graphics, identifies, and relates it to, salient properties of graphics in the art products of the traditional Ibibio society. It also examines the manner in which societal norms and social institutions are fundamental to the art forms proportionate to the communicative indices. The methodology for this study includes in situ study, formalism, iconographic studies and library research. The paper concludes that graphics is a crucial index in the arts of the traditional Ibibio society of Nigeria and, indeed, Africa. (shrink)

The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the (...) development of the community-based Coronavirus Infectious Disease Ontology in early 2020. -/- As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment. -/- CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications. (shrink)

Current COVID-19 pandemic and previous SARS/MERS outbreaks have caused a series of major crises to global public health. We must integrate the large and exponentially growing amount of heterogeneous coronavirus data to better understand coronaviruses and associated disease mechanisms, in the interest of developing effective and safe vaccines and drugs.

This study evaluated the quality of educational resources vis-à-vis effective instructional service delivery in Nigerian universities. Particularly, the study was carried out in university of Calabar, using five hundred and nineteen (519) students selected through the simple random sampling technique from the fifteen faculties of the University of Calabar. To achieve the purpose of the study, two hypotheses were formulated. A questionnaire titled quality of educational resources and effectiveness of instructional service delivery questionnaire (QEREISDQ) was developed by the researchers, this (...) was subjected to face and content validity by three experts in measurement and evaluation and Administration of Higher education all in Faculty of Education University of Calabar. A pilot test was carried out using forty students from University of Uyo in Akwa Ibom state to establish the reliability of the instrument. Using the Cronbach’s alpha reliability method, the instrument had a reliability coefficient of α=.79-.85. The instrument was administered to the respondents and retrieved with Zero attrition rate. The data collected was analyzed through means, standard deviation, Pearson product moment correlation and multiple regression analysis. It was revealed among other things that; the quality of educational resources has a significant relationship with effective of instructional service delivery, with the quality of lecturers being the strongest predictor of effective instructional delivery. However, it was also revealed that the quality of library was significantly low and influenced effective instructional delivery negatively. It was therefore, recommended that government and corporate organizations should provide adequate educational resources and promote viral development programmes for lecturers to enhance effective instructional delivery in Nigerian universities.

John Smith was among the first of the Cambridge Platonists. He was therefore in a position to influence not only his contemporaries but all those who followed after him well into the twentieth century and beyond. Well established lines of influence both to and from Whichcote, Cudworth, and More are explored first before moving on to less well-known connections to Bishop Simon Patrick and mathematician Isaac Barrow. Smith’s continued significance for eighteenth century theology is demonstrated through discussion of his (...) inspiration of the doctrines of spiritual sensation developed by Jonathan Edwards and John Wesley. Special notice is also given to Smith’s authority as an interpreter of Biblical prophecy through the eighteenth and nineteenth centuries. The chapter concludes with looks at Smith’s influence on Samuel Taylor Coleridge, Ralph Waldo Emerson, William Ralph Inge, Rufus Jones, Pierre Hadot, and others. This chapter, offers a broad, but highly selective, overview of the reception and influence of Smith’s life and work. It is intended, however, as a call for future research more than as an authoritative presentation of Smith’s legacy. For, if the Cambridge Platonists have been underappreciated until recently, none of them have been unjustly ignored as consistently as Smith. (shrink)

2024 marks the 400th anniversary of the publication of Theodor Smising’s giant volume De Deo Uno (printed in Antwerp in 1624), which was soon followed by a second volume, De Deo Trino (printed in Antwerp in 1626). Smising’s work was the first printed output of what developed into a specific tradition within early modern thought, the Louvain tradition of Scotism, itself but one part of the broad Scotist tradition that build upon the thought of John Duns Scotus (ca. 1266–1308). (...) This Louvain tradition was primarily based in the Franciscan Convent of the Holy Trinity in the famous university town. The convent itself was much older, dating back to around 1230, when the Franciscan Order was in its very beginnings and long before the University of Louvain was founded (in 1425). In 1607 a second Franciscan Convent was founded in Louvain, St. Anthony’s College, one of a series of convents established by the Irish Franciscans as a result of their persecution in their homeland by the English Protestant rulers. The Irish Franciscans in Louvain, and in their other convents on the European continent, also cultivated the intellectual heritage of Duns Scotus, editing and commenting on his works and writing new works “ad mentem Scoti.” Both of the Franciscan convents in Louvain were closed in the turmoil after the French Revolution. The buildings of St. Anthony’s College still exist, whereas the older “Minderbroedersklooster” (on our exhibition poster) completely vanished from the cityscape. In recent decades, the Maurits Sabbe Library has acquired a large fund of Franciscan books, mostly from various houses of the Franciscan Order in Belgium that have closed their doors. Our exhibition “Scotism Made in Louvain – The Scholastic Culture of the Franciscans in Belgium” explores this material, complemented by material from the KU Leuven Central Library’s Special Collections and two manuscripts from the archives of KADOC (Documentatie- en Onderzoekscentrum voor Religie, Cultuur en Samenleving). The exhibition tells the story of a significant local scholarly tradition which is placed in the context of the broader Scotist tradition of the Early Modern Period. Whereas Scholasticism as such is often seen as an exclusively medieval phenomenon, our exhibition highlights one important aspect of early modern scholastic culture. The three brief articles included in this catalogue provide an introduction to John Duns Scotus’s thought, investigate the institutional background of Louvain Scotism, and explore some of the most important aspects of the scholastic output of the Franciscans in Louvain. The numbers attached to the images refer to the annotated list of all exhibits. A virtual exhibition with additional photo material will accompany, and last beyond, the library exhibition. (shrink)

The paper presents a preliminary estimation of the extent of dissemination of optical texts, ideas, and issues among the masters connected with the Prague faculty of arts in the late 14th and early 15th century. Investigation of this topic, so far rather neglected, is based chiefly on manuscript research. The paper brings evidence that perspectiva was taught in Prague at least since the 1370s. It suggests that investigation of Prague quodlibetal disputations (ca. 1390s – 1410s) and consideration of perspectivist authorities (...) employed in these texts can also shed some light on the issue. However, the paper is mainly devoted to the question on the mechanism of vision disputed by Bohemian arts master John of Borotín (Iohannes de Borotin, 1378 – after 1458) in the quodlibet organised by John Hus in 1411. It is suggested that the single extant exemplar of the question (preserved in the codex Prague, National Library, X.H.18) probably is Borotín’s autograph. The structure and sources of the question are analysed, with the conclusion being that Borotín proposes a compromise between intromission and extramission influenced by John Peckham’s Perspectiva communis. A critical edition of Borotín’s question is appended to the paper. / / / Please note this article is published with Brepols Publishers as a Gold Open Access article under a Creative Commons CC 4.0: BY-NC license.

John Schlitpacher (†1482), who was prior of Melk in the 15th century, encouraged both the circulation of manuscripts at his Abbey and their transcription, even in abbreviated form to the benefit of the Abbey School students. This article looks at the sources and diffusion of texts to and from Melk Abbey in that period, examining the case of a codex purchased by Nicholas of Cusa, registered in his Library as no. 58, and subsequently loaned to the monks in (...) Melk to be copied. It contained the Scala Paradisi by John Climacus and the De spiritualibus deliciis by John of Dambach. In the article, I underline that both of these works, copied in codex 58, were in accordance with John Gerson’s theological approach, which was prevalent in Melk at that time. Moreover, I confirm that there are doctrinal similarities between the two works mentioned above and two, hitherto, unedited writings by Schlitpacher from the same period – the treatise De ascensionibus cordis, which is a summary of the De spiritualibus ascensionibus by Gerard Zerbolt of Zutphen, and another entitled De felicitate beatorum (or De gaudiis electorum).

The National Library of France owns an uncommon illuminated manuscript of the Book of Job : the Parisinus graecus 135. Written in Greek in 1361/62, it is illustrated with a very large iconographic cycle , which combines Byzantine and gothic styles. The examination of the historical background allows us to bring forth the general meaning of the manuscript and to locate its origin with some probability in the Papal entourage and the Byzantine latinophile circles. The analysis of the iconographic (...) cycle of the manuscript shows that it is likely inspired by the theology developed in the literal commentary of Thomas of Aquinas on the Book of Job. Remarkably, this author is intensively translated in Greek in the middle of the fourteenth century in Byzantium under the aegis of the Emperor John VI Cantacuzenus. (shrink)

In 1930, John Maynard Keynes published a masterpiece that should be a compulsory reading for any educated person, a short essay entitled Economic Possibilities for our Grandchildren (Keynes 1930, 1972).All references are from the 1931 online version of Keynes (1930) provided by Project Gutenberg, so pages are left unspecified. I am sure Keynes would have found such free access to information coherent with the philosophy of the essay. It was an attempt to see what life would be like if (...) peace, prosperity and techno-scientific developments were increasingly part of humanity’s future. Of course, things went otherwise. The Great Depression begun in the same year, and World War II soon followed. In the subsequent decades, other disasters, conflicts and crises awaited humanity.

Judging by our folk appraisals, then, knowledge and action are intimately related. The theories of rational action with which we are familiar leave this unexplained. Moreover, discussions of knowledge are frequently silent about this connection. This is a shame, since if there is such a connection it would seem to constitute one of the most fundamental roles for knowledge. Our purpose in this paper is to rectify this lacuna, by exploring ways in which knowing something is related to rationally acting (...) upon it, defending one particular proposal against anticipated objections.

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere continuum idealizations (...) and by reason of this circumstance conceal the information-theoretic source from which they derive. (4) No element in the description of physics shows itself as closer to primordial than the elementary quantum phenomenon, that is, the elementary device-intermediated act of posing a yes-no physical question and eliciting an answer or, in brief, the elementary act of observer-participancy. Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit. (shrink)

Argumentations are at the heart of the deductive and the hypothetico-deductive methods, which are involved in attempts to reduce currently open problems to problems already solved. These two methods span the entire spectrum of problem-oriented reasoning from the simplest and most practical to the most complex and most theoretical, thereby uniting all objective thought whether ancient or contemporary, whether humanistic or scientific, whether normative or descriptive, whether concrete or abstract. Analysis, synthesis, evaluation, and function of argumentations are described. Perennial philosophic (...) problems, epistemic and ontic, related to argumentations are put in perspective. So much of what has been regarded as logic is seen to be involved in the study of argumentations that logic may be usefully defined as the systematic study of argumentations, which is virtually identical to the quest of objective understanding of objectivity.

We think we have lots of substantial knowledge about the future. But contemporary wisdom has it that indeterminism prevails in such a way that just about any proposition about the future has a non-zero objective chance of being false.2, 3 What should one do about this? One, pessimistic, reaction is scepticism about knowledge of the future. We think this should be something of a last resort, especially since this scepticism is likely to infect alleged knowledge of the present and past. (...) One anti-sceptical strategy is to pin our hopes on determinism, conceding that knowledge of the future is unavailable in an indeterministic world. This is not satisfying either: we would rather not be hostage to empirical fortune in the way that this strategy recommends. A final strategy, one that we shall explore in this paper, is one of reconciliation: knowledge of a proposition is compatible with a subject’s belief having a non-zero objective chance of error.4 Following Williamson, we are interested in tying knowledge to the presence or absence of error in close cases, and so we shall explore the connections between knowledge and objective chance within such a framework. We don’t want to get tangled up here in complications involved in attempting to formulate a necessary and sufficient condition for knowledge in terms of safety. Instead, we will assume the following rough and ready necessary condition: a subject knows P only if she could not easily have falsely believed P.5 Assuming that easiness is to be spelt.. (shrink)

This paper argues for externalism about justification on the basis of thought experiments. I present cases in which two individuals are intrinsically and introspectively indistinguishable and in which intuitively, one is justified in believing that p while the other is not.

I isolate what I take to (...) be the most plausible form of privileged access to justification and show that it is compatible with externalism. (shrink)

The second section is a self-contained exposition, including detailed definitions, of a proof that every mathematical system whose domain is the closure of its set of distinguished individuals under its distinguished functions is categorically characterized by its induction principle together with its true atoms (atomic sentences and negations of atomic sentences). The third section deals with applications especially those (...) involving the distinction between characterizing a system and axiomatizing the truths of a system. (shrink)

This paper critically evaluates the regress argument for infinitism. The dialectic is essentially this. Peter Klein argues that only an infinitist can, without being dogmatic, enhance the credibility of a questioned non-evident proposition. In response, I demonstrate that a foundationalist can do this equally well. Furthermore, I explain how foundationalism can provide for infinite chains of justification. I conclude that the regress argument for infinitism should not convince us.

[Edited from Conclusion section:] We have looked at various challenging issues to do with getting connectionism to cope with high-level cognitive activities such a reasoning and natural language understanding. The issues are to do with various facets of generalization that are not commonly noted. We have been concerned in particular with the special forms these issues take in the arena of propositional attitude processing. The main problems we have looked at are: (1) The need to construct explicit representations of generalizations, (...) not just generalize correctly to individual cases; (2) The need to be able to match two or more complex short-term information structures, to enable rapid generalization from recent examples rather than from long-term memories; (3) The need to represent and reason with anomalous combinations of concepts; (4) The need to perform embedded reasoning. This presents special problems for systems using non-concatenative representations (as in mainstream connectionist approaches). We also touched on vague quantification in attitude report complements. Neither this topic nor that of analogies between short-term structures (point 2) has been adequately addressed in the symbolic framework, let alone in connectionism. -/- The opportunities and problems covered are put forward as things worth being optimistic about or pessimistic about, respectively. They are not put forward as decisive arguments for or against connectionism. The hope is that this chapter contributes to a greater understanding of the connectionist/symbolist gap by presenting some unusual issues and by throwing new light on some well known ones. (shrink)

Experiences of embodied remembering are familiar and diverse. We settle bodily into familiar chairs or find our way easily round familiar rooms. We inhabit our own kitchens or cars or workspaces effectively and comfortably, and feel disrupted when our habitual and accustomed objects or technologies change or break or are not available. Hearing a particular song can viscerally bring back either one conversation long ago, or just the urge to dance. Some people explicitly use their bodies to record, store, or (...) cue memories. Others can move skilfully, without stopping to think, in complex and changing environments thanks to the cumulative expertise accrued in their history of fighting fires, or dancing, or playing hockey. The forms of memory involved in these cases may be distinct, operating at different timescales and levels, and by way of different mechanisms and media, but they often cooperate in the many contexts of our practices of remembering.

This is an early volume from a much respected psychedelic psychotherapist. He has written several other books since this one but until recently none of his books were on Amazon and still you can only find a German edition and a Spanish one (from 1993) but no English one (except a couple used copies). This is sad since these drugs have enormous therapeutic potential but afaik government suppression still prevents their use. The most interesting and readable parts are the case (...) histories of drug therapy, especially his own-e.g., on pages 114, 166 and 178. Though a very advanced therapist compared to many, he is far from finished with his intellectual growing up and clings to his psychoanalytic background even though he often mentions its extreme shortcomings. The often painfully awkward text is full of insights from his own therapeutic voyages and those of his patients interspersed with psychoanalytic nonsense. Part of the awkwardness may be due to bad translation from the German but the lack of a rational spiritual framework is a major problem (as with most therapy-or most life for that matter) that he only occasionally seems to recognize. He also sometimes veers off into the ozone-e.g., after many pages of sensible dialog he can opine that varicose veins and cancer are a result of the splitting of a psychosis (p99)! He quotes Zen and Sufi stories, Krishnamurti and Al Ghazali and even Castenada (seemingly unaware of his exposure as a fraud 20 years ago!), yet he seems oblivious to the fact that meditation is the most powerful therapy there is and to the presence around him in his own country and all over the globe of the most diverse and effective therapeutic community that has ever existed-that of the students of the great Indian mystic (ie, psychotherapist) Osho. What a great pity! He could have learned so much and advanced his therapy so far. But like most people he deliberately or unconsciously avoids anything which might wake him up too much. It's possible however that he just avoids mentioning Osho as he's radical enough to trigger the control templates in the monkey brain and enlightenment has the power to change one's whole life and not just put a bandaid on as other therapies usually do. Widmer refers repeatedly to the great LSD therapy pioneer Stanislav Grof, whose writings are one of the first that the interested reader may want to consult. Also, anyone who has a serious interest in psychedelic therapy should read Myron Stolaroff´s " The Secret Chief "-an account of the most remarkable clandestine therapist of this type of all time. It tells the story of the late Leo Zeff, who helped thousands to find themselves with the skilled and varied use of a wide variety of psychedelics. As the book is hard to find you may wish to read the info on Zeff on the web. In addition the clinical chapters in the excellent Ecstasy:the complete guide by J. Holland(2001) and her web page www.drholland.com (and elsewhere on the net) provide a broad framework and guide to therapy that is lacking here. A lovely book to add to any drug or therapy library, if you can find it. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle 59p(2016).

Visualizing and mental imagery are thought to be cognitive states by all sides of the imagery debate. Yet the phenomenology of those states has distinctly visual ingredients. This has potential consequences for the hypothesis that vision is cognitively impenetrable, the ability of visual processes to ground perceptual warrant and justification, and the distinction between cognitive and perceptual phenomenology. I explore those consequences by describing two forms of visual ambiguity that involve visualizing: the ability to visually experience a picture surface as (...) flat after it has caused volumetric nonconceptual contents, and the ability to use a surface initially perceived as flat to visualize three-dimensional scenes. In both cases, the visual processes which extract viewer-centered volumetric shapes have to rely solely on monocular depth cues in the absence of parallax and stereopsis. Those processes can be cognitively penetrated by acts of visualizing, including ones that draw on conceptual information about kinds. However, the penetrability of the visual processes does not weaken their ability to provide perceptual warrant and justification for beliefs. The reason is that picture perceptions—whether they are stimulus -driven or based on acts of visualizing—are different to object perceptions both phenomenologically and in terms of their functional roles as states. Thus, although the penetrability of the visual processes does mean that subjects can have visual experiences with contradictory contents, perceptual belief is adopted at most towards one set of contents, and questions of warrant and justification are raised only for those contents. A rule-proving exception is provided by trompe-l’oeils. (shrink)

Two options are incommensurate in value if neither is better than the other, and if a small improvement or worsening of one does not necessarily make it determinately better or worse than the other. If a person faces a sequence of choices between incommensurate options, she may end up with a worse options than she could have had, even though none of her choices are irrational. Yet it seems that rationality should save her from this bad outcome. This is the (...) practical problem posed by incommensurability of values, and it may be solved by a new account of practical reasoning. (shrink)

The syllogistic figures and moods can be taken to be argument schemata as can the rules of the Stoic propositional logic. Sentence schemata have been used in axiomatizations of logic only since the landmark 1927 von Neumann paper [31]. Modern philosophers know the role of schemata in explications of the semantic conception of truth through Tarski’s 1933 Convention T [42]. Mathematical logicians recognize the role of schemata in first-order number theory where Peano’s second-order Induction Axiom is approximated by Herbrand’s Induction-Axiom (...) Schema [23]. Similarly, in first-order set theory, Zermelo’s second-order Separation Axiom is approximated by Fraenkel’s first-order Separation Schema [17]. In some of several closely related senses, a schema is a complex system having multiple components one of which is a template-text or scheme-template, a syntactic string composed of one or more “blanks” and also possibly significant words and/or symbols. In accordance with a side condition the template-text of a schema is used as a “template” to specify a multitude, often infinite, of linguistic expressions such as phrases, sentences, or argument-texts, called instances of the schema. The side condition is a second component. The collection of instances may but need not be regarded as a third component. The instances are almost always considered to come from a previously identified language (whether formal or natural), which is often considered to be another component. This article reviews the often-conflicting uses of the expressions ‘schema’ and ‘scheme’ in the literature of logic. It discusses the different definitions presupposed by those uses. And it examines the ontological and epistemic presuppositions circumvented or mooted by the use of schemata, as well as the ontological and epistemic presuppositions engendered by their use. In short, this paper is an introduction to the history and philosophy of schemata. (shrink)

Remembering is one of the most characteristic and most puzzling of human activities. Personal memory, in particular – the ability mentally to travel back into the past, as leading psychologist Endel Tulving puts it – often has intense emotional or moral significance: it is perhaps the most striking manifestation of the peculiar way human beings are embedded in time, and of our limited but genuine freedom from our present environment and our immediate needs. Memory has been significant in the history (...) of philosophy as much in relation to ethics and to epistemology as in theories of psyche, mind, and self. (shrink)

Martin and Deutscher’s remarkable 1966 paper ‘Remembering’ still offers great riches to memory researchers across distinctive traditions, both in its methodological ambition (successfully marrying phenomenological and causal discourses) and in its content. In this short discussion, after briefly setting the paper in its context, we hone in on two live and under-explored issues which have gained attention recently under new labels – the extended mind hypothesis, and the constructive nature of memory. We suggest that Martin and Deutscher’s causal analysis of (...) memory is compatible with the idea that activities of remembering may be distributed across heterogeneous social and external resources, focussing in on their neglected example of creatures who ‘remember as we do’ as long as they carry round metal boxes which are given to them at birth. We then argue that the causal analysis is in some tension with the extent to which remembering is a constructive activity, because there may be no clear way to determine the appropriate ‘limits of accuracy’ within which a past event or experience must be represented.

Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be uninformative (...) in the absence of answers to fundamental metaphysical questions like the substantivalist/relationist debate.

A fruitful way to approach The Idea of Phenomenology is through Husserl’s claim that consciousness is not a bag, box, or any other kind of container. The bag conception, which dominated much of modern philosophy, is rooted in the idea that philosophy is restricted to investigating only what is really immanent to consciousness, such as acts and sensory contents. On this view, what Husserl called the riddle of transcendence can never be solved. The phenomenological reduction, as Husserl develops it in (...) The Idea of Phenomenology, opened up a new and broader sense of immanence that embraces the transcendent, making it possible both to solve the riddle and to escape the bag conception once and for all. The essay will discuss ways in which this new conception of immanence is tied to the key Husserlian themes of appearance, phenomenon, essence, seeing or intuiting, and constitution. (shrink)

The Double Content view is the first comprehensive theory of art that is able to satisfactorily explain the nature of all kinds of artworks in a unified way — whether paintings, novels, or musical and theatrical performances. The basic thesis is that all such representational artworks involve two levels or kinds of representation: a first stage in which a concrete artifact represents an artwork, and a second stage in which that artwork in turn represents its subject matter. "Dilworth applies his (...) theory across the arts and to a variety of issues, demonstrating that it has far-reaching implications for our philosophical understanding of the nature of art.” - Stephen Davies, Associate Professor of Philosophy, University of Auckland..

The idea that education should equip people to lead flourishing lives and help others to do so is now becoming salient in policy-making circles. Philosophy of education can help here by clarifying what flourishing consists in. This essay examines one aspect of this. It rejects the view that well-being goods are derivable from human nature, as in the theories of Howard Gardner and Edmond Holmes. It locates them, rather, as cultural products, but not culturally-relative ones, drawing attention to the proliferating (...) forms they have taken over the past three or four centuries. It looks to aesthetics and art criticism as a guide to a philosophical treatment of well-being goods more generally. It also takes off from aesthetics and art criticism in seeking to identify reliable authorities on the flourishing life. On this, it rejects elitist conceptions in favour of a more democratic model, emphasising its importance in education for citizenship. (shrink)

Worrall argued that structural realism provides a ‘synthesis’ of the main pro-realist argument – the ‘No Miracles Argument’, and the main anti-realist argument – the ‘Pessimistic Induction’. More recently, however, it has been claimed that each of these arguments is an instance of the same probabilistic fallacy – sometimes called the ‘base-rate fallacy’. If correct, this clearly seems to undermine structural realism and Magnus and Callender have indeed claimed that both arguments are fallacious and ‘without [them] we lose the rationale (...) for … structural realism ’. I here argue that what have been shown to be fallacious are simply misguided formalisations of ‘the’ arguments and that when they are properly construed they continue to provide powerful motivation for favouring structural realism.

This paper addresses relations between memory and imagery in expert sport in relation to visual or visuospatial perspective. Imagining, remembering, and moving potentially interact via related forms of episodic simulation, whether future- or past-directed. Sometimes I see myself engaged in action: many experts report switching between such external visual perspectives and an internal, 'own-eyes', or field perspective on their past or possible performance. Perspective in retrieval and in imagery may be flexible and multiple. I raise a range of topics for (...) empirical research on perspective and visualization. (shrink)

This paper offers a new account of reflective knowledge’s value, building on recent work on the epistemic norms of speech acts. Reflective knowledge is valuable because it licenses us to make guarantees and promises.

I argue that the physical marks on a canvas resulting from an artist's intentional, stylistic and expressive acts cannot themselves be the artist's expression, but instead they serve to signify or indicate those acts. Thus there is a kind of indicative content associated with a picture that is distinct from its subject matter (or 'representational content'). I also argue that this kind of indicative content is closely associated with the specific artistic medium chosen by the artist as her expressive medium, (...) for which reason I call this kind of content medium content (or medium-related content).

Closure is the epistemological thesis that if S knows that P and knows that P implies Q, then if S infers that Q, S knows that Q. Fred Dretske acknowledges that closure is plausible but contends that it should be rejected because it conflicts with the plausible thesis: Conclusive reasons (CR): S knows that P only if S believes P on the basis of conclusive reasons, i.e., reasons S wouldn‘t have if it weren‘t the case that P. Dretske develops an (...) analysis of knowing that centers on CR, and argues that the requirement undermines skepticism by implying the falsity of closure. We develop a Dretske-style analysis of knowing that incorporates CR, and we argue that this analysis not only accords with closure, but also implies it. In addition, we argue that the analysis accounts for the prima facie plausibility of closure-invoking skeptical arguments, and nonetheless implies that they are fallacious. If our arguments turn out to be sound, the acceptability of Dretske‘s analysis of knowing will be significantly enhanced by the fact that, despite implying closure, it undermines closure-based skepticism.
