Recent studies suggest that lucid dreaming might be associated with increased brain activity over frontal regions during rapid eye movement sleep. By applying transcranial direct current stimulation , we aimed to manipulate the activation of the dorsolateral prefrontal cortex during REM sleep to increase dream lucidity. Nineteen participants spent three consecutive nights in a sleep laboratory. On the second and third nights they randomly received either 1 mA tDCS for 10 min or sham stimulation during each REM period starting with (...) the second one. According to the participants’ self-ratings, tDCS over the DLPFC during REM sleep increased lucidity in dreams. The effects, however, were not strong and found only in frequent lucid dreamers. While this indicates some preliminary support for the involvement of the DLPFC in lucid dreaming, further research, controlling for indirect effects of stimulation and including other brain regions, is needed.

This paper argues for two principal conclusions about natural language semantics based on John Buridan's considerations concerning the notion of formal consequence, that is, formally valid inference. (1) Natural languages are essentially semantically closed, yet they do not have to be on that account inconsistent. (2) Natural language semantics has to be token based, as a matter of principle. The paper investigates the Buridanian considerations leading to these conclusions, and considers some obviously emerging objections to the Buridanian approach.

Straipsnyje nagrinėjama dvejopa machinacijos (Machenschaft) samprata Martino Heideg-gerio technikos filosofijoje. Pirmoji susijusi su Vakarų metafizikos destrukcija (Destruktion) ir jos kulmi-nacija reflektuojama moderniosios technikos plotmėje. Pirmiausiai machinaciją Heideggeris pristato kaip pačios Būties atsivėrimo būdą „pirmoje pradžioje“ (ersten Anfang). Machinacija lemia μετά judesio pamatą, nurodantį į nuolatinę transcendencijos aspiraciją bei „techninį“ esinių atvėrimo pobūdį, nors savo „pajėgumų“ prasme machinacija graikų metafizikoje dar glūdi implicitiškai. Eksplicitiškai machi-nacija pasirodo tik moderniojoje technikoje. Kiek kitokią machinacijos sampratą galime aptikti Heideg-gerio „Juoduosiuose sąsiuviniuose“ (Schwarze Hefte), rašytuose 1931–1938 (...) m. Juose pačią modernybės epochą filosofas pristato kaip machinaciją. Taigi straipsnyje siekiama išryškinti šių dviejų Heideggerio sampratų jungtį, kuri yra machinacijos galios (Macht) augimo tikrovės atžvilgiu nuoroda. (shrink)

Straipsnio tikslas – atskleisti įrankio (Zeug) ir technikos (Technik) skirtumą M. Heideggerio technikos filosofijoje. Analizuojami skirtumai nurodo pasaulio konstitucijos problematiką. Dasein santykį su įrankiu M. Heideggeris pristatė kaip parankų (Zuhandenheit), o štai santykį su technika įvardijo priešingai. Technika, kylanti iš gamtos mokslų, susaistytų machinacija (Machenschaft), filosofo pristatoma kaip Dasein kūrybines galias nuostatyne (Gestell) slopinanti terpė. Straipsnyje atskleidžiama dvejopa problematika. Pirma, parodomi įrankio ir technikos ontologiniai skirtumai. Antra, atskleidžiamas nuostatyno ontologijos ambivalentiškumas. Nuostatynas M. Heideggeriui nėra tik techniškai orientuoto pasaulio užvaldymo mechanizmas, (...) bet ir „gelbstintis“ pradas. (shrink)

Robert Pasnau’s paper presents a strong thesis, which it does not manage to substantiate. The thesis in question is that the Aristotelian doctrine of the identity of the knower and the known, as interpreted by St. Thomas, cannot possibly be used to fend off skepticism.

In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis , of which 26 employed cognitive techniques, 11 external stimulation and one drug application. (...) The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues are discussed and further directions for future studies are proposed.

Daśapadārthī is a text of Indian philosophy and the Vaiśeṣika school only preserved in the Chinese translation made by Xuánzàng 玄奘 in 648 BC. The translation was included in the catalogs of East Asian Buddhist texts and subsequently in the East Asian Buddhist Canons despite clearly being not a Buddhist text. Daśapadārthī is almost unquestionably assumed to be written by a Vaiśeṣika 勝者 Huiyue 慧月 in Sanskrit reconstructed as Candramati or Maticandra. But is that the case? The author argues that (...) the original Sanskrit text was compiled by the Buddhists based on previously existing Vaiśeṣika texts for an exclusively Buddhist purpose and was not used by the followers of Vaiśeṣika. That would explain Xuanzang’s choice for the translation as well as the non-circulation of the text among Vaiśeṣikas. (shrink)

In this paper, I will primarily argue for the consistency of Aquinas’ conception, according to which the human soul, uniquely in God’s creation, is both the inherent, material, substantial form of the human body, and the subsistent immaterial substance underlying the immaterial operations of its immaterial, rational powers, namely, intellect and will. In this discussion, I will point out that typical challenges to Aquinas’ conception usually rely on semantic or ontological assumptions that can plausibly be denied in Aquinas’ own conceptual (...) framework. Since the issue of consistency merely assumes the less than self-evident claim of the immateriality of the human intellect, I will also provide a brief sketch of what I take to be Aquinas’ most promising proof of this claim.

This paper argues that Aquinas's conception of the human soul and intellect offers a consistent alternative to the dilemma of materialism and post-Cartesian dualism. It also argues that in their own theoretical context, Aquinas' arguments for the materiality of the human soul and immateriality of the intellect provide a strong justification of his position. However, that theoretical context is rather "alien" to ours in contemporary philosophy. The conclusion of the paper will point in the direction of what can be done (...) to render Aquinas's position more palatable to contemporary philosophers. (shrink)

Common representational content allows the Buridanian classification of human concepts discussed in the fourth chapter, which provides the first thoroughgoing, systematic survey of Buridan’s conception of a mental language. The chapter discusses the divisions of concepts into syncategorematic and categorematic, simple and complex, absolute and connotative, and singular and common concepts. Besides presenting these classifications, the chapter provides a detailed discussion of the idea of conceptual complexity as semantic compositionality, its role in Buridan’s nominalist program of “ontological reduction,” and his (...) precarious positioning of his account of the distinction between the representational contents of universal and singular concepts “somewhere between” those of Ockham and Aquinas. The discussion relates the emerging issues to contemporary concerns in the philosophy of mind and language, such as the possibility of forming genuinely singular concepts and simple substantial concepts that would allow some terms of our language to function as rigid designators; the differences between consciousness and mental content; and the problem of universal representation without real universals.

Methodological nationalism in sociological theory is unfit for the current globalized era, and should be discarded. In light of this contention, the present article discusses Max Weber’s view of language as a way to relativize the frame of the national society. While a “linguistic turn” in sociology since the 1960s has assumed that the sharing of language—linguistic community—stands as an intersubjective foundation for understanding of meaning, Weber saw linguistic community as constructed. From Weber’s rationalist, subjectivist, individualist viewpoint, linguistic community was (...) a result of social actions, not a prior entity as assumed by German metaphysical organicism (and historicist holism). Indeed, Central Europe in Weber’s era was a battlefield of linguistic nationalism(s); in contrast to the national societies of the Cold War period, national borders were unstable and ultimately the multiethnic empires of the region were dismantled after World War I into ethnolinguistic nation-states. Experience of this contemporary reality brought Weber to the core of the relationship between language and politics: A language community is an imaginary one demarcated not by language itself but by conscious opposition against outsiders, with monolingual contexts within borders created artificially by homogenizing policies like linguistic standardization and national education—the first modernity of language. In this way, Weber felt, language can be a means to domination. (shrink)

The third chapter discusses how Buridan’s conception of mental language provides the grounding for the objectivity and universality of logic despite the radical conventionality of written and spoken languages. Buridan’s conception, since it is based on the Aristotelian idea of the uniformity of natural human capacities in all individual humans, is nothing like modern psychologism, the kind heavily criticized by Frege. Indeed, Buridan’s mental language is not a “private language” criticized by Wittgenstein. On Buridan’s conception, the naturally representative units of (...) human mental language, namely, human concepts, are not inter-subjectively inaccessible private mental states; on the contrary, they are common to us all in our thinking. Of course, our concepts, being individual acts of individual minds are singular token-symbols, but they are common in their representational content: in what and how they represent for all humans. This is precisely the ground for their intersubjective accessibility as well as for the objectivity and universality of logic. (shrink)

Having seen the limitations of a reconstruction of Buridan’s semantics in terms of a modified quantification theory, this chapter begins engaging Buridan’s theory in its own terms, starting with a detailed discussion of the semantic properties of terms. The discussion moves from a brief discussion of Buridan’s distinction between immediate and ultimate signification, to Buridan’s theory of reference, namely, supposition, and oblique reference, namely, appellation. The chapter discusses suppositional descents as distinguishing quantifier-scopes, numerical quantification, and appellation in temporal and modal (...) contexts, as well as Buridan’s peculiar theory of appellatio rationis, the theory of oblique reference to concepts in intentional contexts.

This chapter provides a brief survey of Buridan’s reliabilist epistemology, contrasting it with skeptical challenges of his time, and comparing it with modern responses to similar skeptical challenges in modern philosophy, arguably stemming from the controversies of Buridan’s time. In particular, the chapter argues that the sort of “Demon-skepticism” modern readers are familiar with from Descartes was made conceptually possible precisely by the emergence of late-medieval nominalist semantics, and that the modern strategies responding to the skeptical challenge, exemplified by the (...) works of Thomas Reid and most recently John Greco, originate in the epistemic principles of Buridan.

This chapter provides a systematic discussion of Buridan’s nominalist semantics of propositions and sentential nominalizations. The chapter argues that despite its incompleteness, Buridan’s theory is still “nominalism’s best shot” at a semantics of propositions without buying into a philosophically and theologically dubious ontology of dicta, enuntiabilia, complexe significabilia, real propositions, or states of affairs.

The aim of this article is to explore how a self-referential social system, although it is not a human being, can be said to “observe.” For this purpose, the article reformulates Niklas Luhmann’s theory of social systems as sociological phenomenology, or the de-consciousness philosophized phenomenology, because a social system has the same structure of intentionality as consciousness: Just as consciousness is always consciousness of something, communication is always communication of something. In correlation to this communicative intentionality, communicated environments come and (...) go as social phenomena. A social system is not a thing, but an autonomously observing subject. Hence, this systems theory takes on the role of a second-order observer: It observes how social systems as first-order observers observe self-referentially because phenomena given to the natural attitude of the first-order observer constitute multiple social realities in daily life. Therefore, the theory of self-referential social systems is not objectivism, but a variation of mundane subjectivist phenomenology. (shrink)

This is a brief, accessible introduction to the thought of the philosopher John Buridan (ca. 1295-1361). Little is known about Buridan's life, most of which was spent studying and then teaching at the University of Paris. Buridan's works are mostly by-products of his teaching. They consist mainly of commentaries on Aristotle, covering the whole extent of Aristotelian philosophy, ranging from logic to metaphysics, to natural science, to ethics and politics. Gyula Klima argues that many of Buridan's academic concerns are strikingly (...) similar to those of modern philosophy and his work sometimes quite directly addresses modern philosophical questions.

An argument with roots in ancient Greek philosophy claims that only humans are capable of a certain class of thought termed conceptual, as opposed to perceptual thought, which is common to humans, the higher animals, and some machines. We outline the most detailed modern version of this argument due to Mortimer Adler, who in the 1960s argued for the uniqueness of the human power of conceptual thought. He also admitted that if conceptual thought were ever manifested by machines, such an (...) achievement would contradict his conclusion. We revisit Adler’s criterion in the light of the past five decades of artificial-intelligence research, and refine it in view of the classical definitions of perceptual and conceptual thought. We then examine two well-publicized examples of creative works produced by AI systems and show that evidence for conceptual thought appears to be lacking in them. Although clearer evidence for conceptual thought on the part of AI systems may arise in the near future, especially if the global neuronal workspace theory of consciousness prevails over its rival, integrated information theory, the question of whether AI systems can engage in conceptual thought appears to be still open.

Although initiation of DNA replication is considered to be highly coordinated through multiple protein–DNA and protein–protein interactions, it is poorly understood how particular locations within the eukaryotic chromosome are selected as origins of DNA replication. Here, we discuss recent reports that present structural information on the interaction characteristics of the archaeal orthologues of the eukaryotic origin recognition complex with their cognate binding sequences.1,2 Since the archaeal replication system is postulated as a simplified version of the one in eukaryotes, by analogy, (...) these works provide insights into the functions of the eukaryotic initiator proteins.

When Thomas Luckmann, a pioneer of the “linguistic turn” in sociology, regarded Émile Durkheim as a source for the sociology of language, he had lifeworldly community–building in mind. However, the French sociologist himself understood language in the context ofcivil society–building. To Durkheim, language was a “social thing in the highest degree” that enabled general ideas and intermediated them to people. Abstract human ideals like the civil religion since the French Revolution could be shared through (a common) language. Thus, Durkheim took (...) the exclusive use of French in the Third Republic’s laic public education for granted, ignoring the patois in the country: This “child of the Enlightenment” considered French to be a universal language ofGesellschaftand, beyond ethno-communal elements, to work as a basis for the organic solidarity of French national civil society where the social division of labor was progressing. Durkheim’s theory was predicated on civil-linguistic, not ethnolinguistic, nationalism. (shrink)

I‐J has been regarded as a polymorphic genetic marker controlled by a locus in the major histocompatibility complex (MHC) which is expressed only on functional T cells. However, this antigenic determinant has been found not to be directly encoded by the MHC gene per se but is somatically generated according to the MHC of the cellular environment during ontogeny. This explains the apparent linkage of I‐J to MHC, despite the failure to find the structural gene for I‐J within the MHC. (...) The I‐J paradox provides an instance of a polymorphism that does not follow the standard genetics of Mendelian structural genes. (shrink)

Ca2+ transients in myocardial cells are modulated by cyclic AMP‐dependent phosphorylation of a protein in the sarcoplasmic reticulum. This protein, termed phospholamban, serves to regulate the Ca2+ pump ATPase of this membrane, thus altering the mode of Ca2+ transients and the myocardial contractile response. Elucidating the structure of phospholamban and its intimate interaction with the Ca2+ pump ATPase should provide the basis for understanding, at the molecular level, how the cAMP system contributes to excitation‐contraction coupling in muscle cells.

We argue that at least some corvids morally ought to be granted a right to bodily liberty in the US legal system and relevantly similar systems. This right would grant immunity to frivolous captivity and extermination. Implementing this right will require new legislation or the expansion of existing legislation including the elimination of various "pest" clauses. This paper proceeds in three parts. First, we survey accounts of the moral grounds of legal rights. Second, to establish an overlapping consensus supporting corvid (...) bodily liberty rights, we survey the empirical literature on corvid cognition. Third, we illustrate what a corvid right to bodily liberty might look like, by looking to recent developments in animal law, as well as previous advocacy on behalf of primates and cetaceans.

To what extent is the neural organization of language dependent on factors specific to the modalities in which language is perceived and through which it is produced? That is, is the left-hemisphere dominance for language a function of a linguistic specialization or a function of some domain-general specialization(s), such as temporal processing or motor planning? Investigations of the neurobiology of signed language can help answer these questions. As with spoken languages, signed languages of the deaf display complex grammatical structure but (...) are perceived and produced via radically different modalities. Thus, by mapping out the neurological similarities and differences between signed and spoken language, it is possible to identify modality-specific contributions to brain organization for language. Research to date has shown a significant degree of similarity in the neurobiology of signed and spoken languages, suggesting that the neural organization of language is largely modality-independent.
