Deep brain stimulation of the subthalamic nucleus is a clinically effective tool for treating medically refractory Parkinson’s disease, but its neural mechanisms remain debated. Previous work has demonstrated that STN DBS results in evoked potentials in the primary motor cortex, suggesting that modulation of cortical physiology may be involved in its therapeutic effects. Due to technical challenges presented by high-amplitude DBS artifacts, these EPs are often measured in response to low-frequency stimulation, which is generally ineffective at PD symptom management. This (...) study aims to characterize STN-to-cortex EPs seen during clinically relevant high-frequency STN DBS for PD. Intraoperatively, we applied STN DBS to 6 PD patients while recording electrocorticography from an electrode strip over the ipsilateral central sulcus. Using recently published techniques, we removed large stimulation artifacts to enable quantification of STN-to-cortex EPs. Two cortical EPs were observed – one synchronized with DBS onset and persisting during ongoing stimulation, and one immediately following DBS offset, here termed the “start” and the “end” EPs respectively. The start EP is, to our knowledge, the first long-latency cortical EP reported during ongoing high-frequency DBS. The start and end EPs differ in magnitude and latency, and the end, but not the start, EP magnitude has a significant relationship to ongoing high gamma power during the EP. These contrasts may suggest mechanistic or circuit differences in EP production during the two time periods. This represents a potential framework for relating DBS clinical efficacy to the effects of a variety of stimulation parameters on EPs. (shrink)

To what extent does perceptual language reflect universals of experience and cognition, and to what extent is it shaped by particular cultural preoccupations? This paper investigates the universality~relativity of perceptual language by examining the use of basic perception terms in spontaneous conversation across 13 diverse languages and cultures. We analyze the frequency of perception words to test two universalist hypotheses: that sight is always a dominant sense, and that the relative ranking of the senses will be the same across different (...) cultures. We find that references to sight outstrip references to the other senses, suggesting a pan-human preoccupation with visual phenomena. However, the relative frequency of the other senses was found to vary cross-linguistically. Cultural relativity was conspicuous as exemplified by the high ranking of smell in Semai, an Aslian language. Together these results suggest a place for both universal constraints and cultural shaping of the language of perception. (shrink)

Apart from references to perception, words such as see and listen have shared, non-literal meanings across diverse languages. Such cross-linguistic meanings have not been systematically investigated as they appear in their natural home — informal spoken interaction. We present a qualitative examination of the semantic associations of perception verbs based on recorded everyday conversation in thirteen diverse languages. Across these diverse communities, spontaneous interaction provides evidence for two commonly-discussed extensions of perception verbs — perception~cognition, hearing~linguistic communication — as well as (...) illustrating other meanings and functions that have been less appreciated heretofore. The range of usage that is readily observable in informal conversation makes it clear that this type of data must take center stage for the empirically grounded study of semantics. Moreover, these data suggest that commonalities in polysemous meanings may rely not only on universal cognition, but also on the universal exigencies of social interaction. (shrink)

In these times of rapid change and constant upheaval, can we learn to think and communicate more effectively-at home, in school, on the job, and as citizens of the larger world? This book (like its predecessor Sensible Thinking for Turbulent Times), which is based on the formulations of general semantics, says yes, yes, and yes! Topics in it include practical ways to improve your thinking ability, emotional self-management, understanding of the media, and analysis of important social issues.

This book, which is based on the formulations of general semantics, offers useful information on a wide variety of topics (e.g., managing stress, enhancing creativity, communicating more effectively). It also provides cogent analysis of social issues (e.g., America's current foreign policy, communication in the internet age); offers ideas to help people be more successful at work (e.g., "How to Become a More Successful Leader," "How to Effectively Manage Your Career"); and includes suggestions to help children be more successful in school (...) (e.g.," Reducing School-Age Bullying," "Anger and Violence Prevention"). (shrink)

Stephen Yablo has attempted recently to revive the notion of contingent identity, identifying this with a relation of L coincidence between objects that are "distinct by nature but the same in the circumstances" (296). Yablo argues convincingly for the need of essentialist metaphysics to recognize some relation of this sort, a relation of "intimate identity-like connections between things" (296) if it is to acknowledge properly the intuitive difference between (i) the nonidentity of a bust B and a hunk of wax (...) H of which it is composed, and (ii) the nonidentity of the hunk H and the Treaty of Versailles. (i) and (ii) are clearly not on the same level. Even though B, like the Treaty of Versailles, fails to be strictly identical to H, it is very closely, and quite specially, related to it. What this relation is is certainly worth a general inquiry.

In this paper, I hope to reintroduce debate on the issue of aesthetic supervenience, especially in light of work undertaken by metaphysicians in recent years. After providing a brief walkthrough of some of the major views on supervenience generally, including several important metaphysical distinctions, I build upon views by Jerrold Levinson, John Bender, Nick Zangwill, and Gregory Currie, to develop a realist thesis of strong local supervenience, such that aesthetic properties of artworks and other objects depend upon their formal/structural (...) properties and reduce to powers to produce aesthetic effects of particular kinds in suitable perceivers under suitable conditions.

This paper examines a general political problem of how to balance the need for concentrated power in the hands of the state—which is needed for effective governance—against the egalitarian desire to equalize power. It distinguishes between ‘positive’ political power appropriately wielded by the state, and ‘negative’ power that individuals may use to protect their own activities and interests from excessive or illegitimate state action and argue for institutions and practices designed to equalize power by ‘leveling up’ the powerless to match (...) the strong.

The article proposes to defend the basic income as a pillar of a socio-cultural revolution. This is done exclusively from a literature review and articulation of different works. The introduction section presents the characteristics of a basic income. Section 2 brings how it would mitigate current capitalism problems, which are: increasing inequality, lack of equality of opportunity, means tested social security and its bureaucracy, narrow definition of paid work and future of labor. On Section 3, the author does a literature (...) review to address two common objections against basic income: the cost, and potential labor decrease. Section 4 presents the author argument on three pillars of the socio-cultural revolution: austerity, active citizenship, and solidarity. The article ends with a general conclusion. (shrink)

Conventionality and aptness are two dimensions of metaphorical sentences thought to play an important role in determining how quick and easy it is to process a metaphor. Conventionality reflects the familiarity of a metaphor whereas aptness reflects the degree to which a metaphor vehicle captures important features of a metaphor topic. In recent years it has become clear that operationalizing these two constructs is not as simple as asking naïve raters for subjective judgments. It has been found that ratings of (...) aptness and conventionality are highly correlated, which has led some researchers to pursue alternative methods for measuring the constructs. Here, in four experiments, we explore the underlying reasons for the high correlation in ratings of aptness and conventionality, and question the construct validity of various methods for measuring the two dimensions. We find that manipulating the processing fluency of a metaphorical sentence by means of familiarization to similar senses of the metaphor (“in vivo conventionalization”) influences ratings of the sentence's aptness. This misattribution may help explain why subjective ratings of aptness and conventionality are highly correlated. In addition, we find other reasons to question the construct validity of conventionality and aptness measures: for instance, we find that conventionality is context dependent and thus not attributable to a metaphor vehicle alone, and we find that ratings of aptness take more into account than they should.

Scientific knowledge relies heavily on models, shaped by simplifying assumptions, with common categories being abstraction and idealization. This article aims to expose conceptual challenges inherent in conventional interpretations of these concepts, particularly in their practical application to scientific modeling. The primary hurdle emerges in applying these categories to real­world instances of scientific modeling, which we illustrate with examples of non­causal explanations. Key issues revolve around (i) the ambiguous distinction between abstraction and idealization and (ii) the application of the simplifying assumption (...) of abstraction. Our hypothesis posits that non­causal explanations face unintelligibility due to an unclear understanding of the role of simplifying assumptions in them. To test this, we analyze selected examples, ranging from (toy­)examples to real­world instances, scrutinizing the alignment with the standard notions of abstraction and idealization. Throughout, we investigate the influence of simplifying assumptions on these explanations, assessing their adherence or deviation from conventional concepts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:James's Faith-Ladder JAMES C. S. WERNHAM JAMES WROTE OFTEN of a "faith-ladder."' What he said about it has drawn some side-glances from critics, but not yet any sustained and careful look.' That is surprising, for what he says is puzzling enough to invite inquiry. It is also important enough to deserve it. His presentations of the ladder show significant variation, so it is useful to look at a generous (...) sample. In the interest of brevity the following six passages have been extracted from contexts which sometimes have an important bearing on them. The unquoted contexts will get attention as needed. 1. "The inner process is a succession of 'synthetic judgments'. What is so good, may be, ought to be, must be, shall be,--so far as I am concerned, I won't admit the opposite. ''s 2. "[W]e have a conception which being opposed by another is only probab /e. But we feel, it is so good that it isfit to be true, it ought to be true, it must be true etc. And then we say it shall be true for me, it/s true. ''4 3- "Its [faith's] natural logic is the Sorites: fit to be, ought to be, may be, must be, shall be, is etc.''5 4. "The following steps may be called the 'faith-ladder': ~. There is nothing absurd in a certain view of the world being true, nothing self-contradictory; ' To the best of my knowledge, the name "faith-ladder'"does not occur before 19o6. It occurs in "Faith and Reason" and in "Faith and the Right to Believe," both written in that year. But expositions of the thing predate the name. They are found as early as 1899, and in close connection with the will-to-believe doctrine. 9 Levinson's discussion is a partial exception. His treatment is more extended than most. See H. S.

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated or somehow (...) benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

The COVID-19 pandemic caused university education to transition from face-to-face contacts to virtual learning environments. Young adults were forced to live an entirely new life online, without valuable and enjoyable social interaction. We examined subjective perspectives towards life online during the pandemic. We identified four viewpoints about life mediated by computers. Two viewpoints express “struggling”: Viewpoint 1 (Angry, Depressed and Overwhelmed), and Viewpoint 3 (Restricted to and Overwhelmed by Virtuality). A third feeling-state conveys experiences of “surviving”: Viewpoint 4 (Isolated and (...) Powerless in Convenience). Surprisingly, Viewpoint 2 is about “thriving” (Comfortable and Convenient Routine with Computers). The research shows that virtualization, confinement, and anxiety are taking a toll on the mental health of some members of the younger generation, while at the same time other members feel they are thriving in a situation of limited resources, virtuality, and reduced face-to-face human interaction.

In this book, Phillip Wiebe examines religious, spiritual, and mystical experiences, assessing how these experiences appear to implicate a spiritual order. Despite the current prevalence of naturalism and atheism, he argues that experiences purporting to have a religious or spiritual significance deserve close empirical investigation. Wiebe surveys the broad scope of religious experience and considers different types of evidence that might give rise to a belief in phenomena such as spirits, paranormal events, God, and an afterlife. He demonstrates that there (...) are different explanations and interpretations of religious experiences, both because they are typically personal accounts, and they suggest a reality that is often unobservable. Wiebe also addresses how to evaluate evidence for theories that postulate unobservables in general, and a Theory of Spirits in particular. Calling for more rigorous investigation of these phenomena, Wiebe frames the study of religious experience among other accepted social sciences that seek to understand religion. (shrink)

Priority setting is inevitable to control expenditure on expensive medicines, but citizen support is often hampered by the workings of the ‘identified victim effect’, that is, the greater willingness to spend resources helping identified victims than helping statistical victims. In this paper we explore a possible cognitive debiasing strategy that is being employed in discussions on healthcare priority setting, which we call ‘empathy counterbalancing’ (EC). EC is the strategy of directing attention to, and eliciting empathy for, those who might be (...) harmed as a result of one-sided empathy for the very ill who needs expensive treatment. We argue that governments have good reasons to attempt EC because the identified victim effect distorts priority setting in ways that undermine procedural fairness. We briefly outline three areas of application for EC and suggest some possible mechanisms that might explain how EC might work, if at all. We then discuss four potential ethical concerns with EC. First, EC might have the counterproductive effect of reducing overall citizen support for public funding of expensive medical treatments, thereby undermining solidarity. Second, EC may give rise to a ‘competition in suffering’, which may have unintended side effects for patients who feature in attempts at EC. Third, there may be doubts about whether EC is effective. Fourth, it may be objected that EC comes down to emotional manipulation, which governments should avoid. We conclude that insofar these concerns are valid they may be adequately addressed, and that EC seems a promising strategy that merits further investigation. (shrink)

This study was an attempt to investigate the nature of metaphor by doing a cross-cultural comparison of metaphor in 2 typologically different languages-English and Persian. For this purpose, animal metaphors were taken for comparison. The "GREAT CHAIN OF BEING" metaphor (Lakoff & Turner, 1989), along with the principle of metaphorical highlighting (Kovecses, 2002), were used as a framework in comparing different aspects of animal metaphors as interpreted by native speakers of the 2 languages. The results showed that although animal metaphors (...) in English and Persian are similar to a certain extent, many aspects of them are culture-specific. The similarities and differences among 44 animal metaphors in these 2 languages are shown and some possible explanations are put forward. (shrink)

In the 1950s, Chomsky and his colleagues began attempts to reduce the complexity of natural language phonology and syntax to a few general principles. It wasn’t long before philosophers, notably John Searle and H. Paul Grice, started looking for ways to do the same for rational communication (Chapman 2005). In his 1967 William James Lectures, Grice presented a loose optimization system based on his maxims of conversation. The resulting papers (especially Grice 1975) strike a fruitful balance between intuitive exploration and (...) formal development. Though the work is not particularly formal, it marks the birth of modern formal pragmatics. Pragmatics is central to the theory of linguistic meaning because, to paraphrase Levinson (2000), the encoded content of the sentences we utter is only the barest sketch of what we actually communicate with those utterances. Utterance interpretation involves complex interactions among (i) semantic content, (ii) the context of utterance, and (iii) general pragmatic pressures (of which Grice’s maxims are one conception). The starting point for a formal pragmatics is the observation that speakers agree to a remarkable extent on the interpretations of the utterances they hear, suggesting that there are deep regularities across speakers, utterance contexts, and sentence types in how (i)–(iii) interact. An overarching challenge for pragmatic theory is that semantic content and the context of utterance influence each other. It is common, for instance, to find that the meaning of a sentence is crucially incomplete without contextual information. Indexicals and demonstratives are paradigm cases: ‘I am here now’ doesn’t have a fully specified denotation without information about who the speaker is, when he is speaking, and where he is speaking. Similarly, modal auxiliaries like must admit of a wide range of interpretations.. (shrink)

The Political Crisis and Christian Ethics addresses themes in political philosophy in the context of a crisis in democracy after the denial of the 2020 election by the Republican candidate for president. The refusal to accept the results of the election divided the electorate and drove the president's followers to fail in their attempted coup attempt in January of 2020. Democracy is defended in Reinhold Niebuhr's writing on politics and in Barack Obama's use of the theologian's thought. It is developed (...) further in the political theory of Paul Tillich. The themes of just peacemaking are reviewed in Paul Tillich's critique of John Foster Dulles' work and in the author's critique of just peacemaking in the work of Glen Stassen. Domestically the issues of race, inequality, ecology, and healthcare are addressed from the perspective of prophetic realism. The book concludes in terms of Alfred North Whitehead's philosophy of education and religion and a vision of the good president. In summary, The Political Crisis and Christian Ethics is a volume of American, Christian political theory in a period of overcoming the trauma of 2016 with Christian ethics and political philosophy.
