In past and modern psychophysics there are several unresolved methodological and philosophical problems of human and animal perception, including the outstanding question of the relational basis of whole psychophysics. Here the main issue is discussed: if, and to what extent, there are viable bridges between the traditional “gestalt” oriented approaches and the modern perceptual-cognitive perspectives in psychophysics. Thereby the key concept of psychological “frame of reference” is presented by pointing to Hermann Ebbinghaus' geometric-optical illusions, on the one hand, and Max (...) Wertheimer's treatment of the traditional transposition phenomenon, on the other hand. A much-needed theoretical reorientation of future research may help to overcome the philosophical narrowness of present-day human and comparative psychophysics. (shrink)

Hutto and Satne, Philosophia propose to redefine the problem of naturalizing semantic content as searching for the origin of content instead of attempting to reduce it to some natural phenomenon. The search is to proceed within the framework of Relaxed Naturalism and under the banner of teleosemiotics which places Ur-intentionality at the source of content. We support the proposed redefinition of the problem but object to the proposed solution. In particular, we call for adherence to Strict Naturalism and replace teleosemiotics (...) with autopoietic theory of living beings. Our argument for these adjustments stems from our analysis of the flagship properties of Ur-intentionality: specificity and directedness. We attempt to show that the first property is not unique to living systems and therefore poses a problem of where to place a demarcation line for the origin of content. We then argue that the second property is a feature ascribed to living systems, not their intrinsic part and therefore does not form a good foundation for the game of naturalizing content. In conclusion we suggest that autopoietic theory can not only provide a competitive explanation of the basic responding of pre-contentful organisms but also clarify why Ur-intentionality is attributed to them in such an intuitive manner.

Claude Perrault, a founding member of the Académie des sciences and architect of the Louvre, is a figure emblematic of architecture’s transformation by the so-called scientific revolution, representing a radical break with tradition. This article will address Perrault’s scientific challenge to architecture as one that harks back to both ancient and modern sources. It explores some ways in which Perrault integrated the analogy between medicine and architecture into his approach to this art and assimilated medical concepts, particularly observation, into an (...) empirical medical approach. This notion of observation was at the heart of the practical aspect of ancient philosophy as a care of the soul which articulated the ancient comparison of the charismatic orator to a doctor. Thus, Perrault’s remarks on Vitruvius’s authority can be broadened beyond architecture to the quest for a guide to living, transcending disciplinary boundaries between natural science and art. Further, Perrault’s claims for naturalness in observation share a double perspective: observation as a new form of learned experience reflects the ethos of the scientist, while, as a traditional activity of peasants, it reflects a raw empirical knowledge about rules of life condensed into habit and custom, enabling common people to be the physicians of themselves.

In his Foundations of a General Theory of Manifolds, Georg Cantor praised Bernard Bolzano as a clear defender of actual infinity who had the courage to work with infinite numbers. At the same time, he sharply criticized the way Bolzano dealt with them. Cantor’s concept was based on the existence of a one-to-one correspondence, while Bolzano insisted on Euclid’s Axiom of the whole being greater than a part. Cantor’s set theory has eventually prevailed, and became a formal basis of contemporary (...) mathematics, while Bolzano’s approach is generally considered a step in the wrong direction. In the present paper, we demonstrate that a fragment of Bolzano’s theory of infinite quantities retaining the part-whole principle can be extended to a consistent mathematical structure. It can be interpreted in several possible ways. We obtain either a linearly ordered ring of finite and infinitely great quantities, or a partially ordered ring containing infinitely small, finite and infinitely great quantities. These structures can be used as a basis of the infinitesimal calculus similarly as in non-standard analysis, whether in its full version employing ultrafilters due to Abraham Robinson, or in the recent “cheap version” avoiding ultrafilters due to Terence Tao.

Following François Laruelle's nonstandard philosophy and the work of Judith Butler, Drucilla Cornell, Luce Irigaray, and Rosi Braidotti, Katerina Kolozova reclaims the relevance of categories traditionally rendered "unthinkable" by postmodern feminist philosophies, such as "the real," "the one," "the limit," and "finality," thus critically repositioning poststructuralist feminist philosophy and gender/queer studies. Poststructuralist (feminist) theory sees the subject as a purely linguistic category, as _always alread_y multiple, as _always already_ nonfixed and fluctuating, as limitless discursivity, and as constitutively detached from (...) the instance of the real. This reconceptualization is based on the exclusion of and dichotomous opposition to notions of the real, the one (unity and continuity), and the stable. The non-philosophical reading of postructuralist philosophy engenders new forms of universalisms for global debate and action, expressed in a language the world can understand. It also liberates theory from ideological paralysis, recasting the real as an immediately experienced human condition determined by gender, race, and social and economic circumstance. (shrink)

Phenotypic plasticity is a crucial feature of aggressive cancer, providing the means for cancer progression. Stochastic changes in tumor cell transcriptional programs increase the chances of survival under any condition. I hypothesize that unstable chromatin permits stochastic transitions between transcriptional programs in aggressive cancers and supports non‐genetic heterogeneity of tumor cells as a basis for their adaptability. I present a mechanistic model for unstable chromatin which includes destabilized nucleosomes, mobile chromatin fibers and random enhancer‐promoter contacts, resulting in stochastic transcription. I (...) suggest potential markers for “unsettled” chromatin in tumors associated with poor prognosis. Although many of the characteristics of unstable chromatin have been described, they were mostly used to explain changes in the transcription of individual genes. I discuss approaches to evaluate the role of unstable chromatin in non‐genetic tumor cell heterogeneity and suggest using the degree of chromatin instability and transcriptional noise in tumor cells to predict cancer aggressiveness.

In this essay, I propose that DNA‐binding anti‐cancer drugs work more via chromatin disruption than DNA damage. Success of long‐awaited drugs targeting cancer‐specific drivers is limited by the heterogeneity of tumors. Therefore, chemotherapy acting via universal targets (e.g., DNA) is still the mainstream treatment for cancer. Nevertheless, the problem with targeting DNA is insufficient efficacy due to high toxicity. I propose that this problem stems from the presumption that DNA damage is critical for the anti‐cancer activity of these drugs. DNA (...) in cells exists as chromatin, and many DNA‐targeting drugs alter chromatin structure by destabilizing nucleosomes and inducing histone eviction from chromatin. This effect has been largely ignored because DNA damage is seen as the major reason for anti‐cancer activity. I discuss how DNA‐binding molecules destabilize chromatin, why this effect is more toxic to tumoral than normal cells, and why cells die as a result of chromatin destabilization. (shrink)

This article discusses findings of a qualitative study on strategies of othering observed in anti-immigrant discourse, by analysing selected examples from the UK and Polish media, together with data collected from interviews with migrants. The purpose is to identify discursive strategies of othering, which aim to categorise, denigrate, oppress and ultimately reject the stigmatised or racialised ‘other’. We do not offer a systematic comparison of the data from the UK and Poland; instead, we are interested in what is common in (...) the discursive practices of these two countries/contexts. In using newspaper together with interview data, we are combining representation and experience in identifying not only strategies of othering, but also how these are perceived by and affect the othered individuals. The paper uses the following data: 40 newspaper articles – 20 from the UK and 20 from Poland, and 19 interviews – 12 from Poland and 7 from the UK. The analysis that follows identifies five shared strategies of othering: a) Stereotyping; b) Whiteness as the norm; c) Racialisation; d) Objectification; e) Wrongly Ascribed Ethnicity. We conclude with the research limitations and outlining possible next stages, such as working with a larger corpus, investigating frequency, or including other media genres. (shrink)

Thought experiments being central to contemporary philosophy and science, the following questions were asked in recent literature. What is their definition? Are they heuristic devices, arguments, paradoxes? Are they comparable to real experiments? Do intuition and conceivability intervene? Equally imaginative thought experiments are found in ancient, medieval, and Renaissance texts. Paying attention to prime historical examples of thought experiments, we show that historical perspectives help answer these general questions.

The article focuses on a method for collecting qualitative data. The method is the asynchronous email interview. The authors assess the advantages, challenges and best practices of the asynchronous email interview method. They base their assessment on the academic literature and their own experiences using this data collection method in qualitative research on women who had experienced perinatal loss. The asynchronous email interview will never fully replace traditional face-to-face interviews, but it could gain a solid position as a qualitative research (...) method thanks to its unique benefits.

The potential of surveillance practices to undermine the presumption of innocence is a growing concern amongst critics of surveillance. This paper attempts to assess the impact of surveillance on the presumption of innocence. It defends an account of the presumption of innocence as a protection against wrongful criminalisation against alternatives, and considers both the ways in which surveillance might undermine that protection and the—hitherto overlooked—ways in which it might promote it. It draws on empirical work on the causes of erroneous (...) convictions to suggest that surveillance can be used in ways that prevent innocent people being erroneously charged and convicted with crimes, by providing a source of exculpatory evidence for use in police investigations. It is argued that surveillance practices do not necessarily undermine the presumption of innocence but can be reformed in ways that both reduce the risk that they will cause wrongful criminalisation and increase their power to protect those already under suspicion.

Cognitive and emotional processes are now known to be intertwined and thus the limbic system that underlies emotions is important for human brain evolution, including the evolution of circuits supporting language. The neural substrates of limbic functions, like motivation, attention, inhibition, evaluation, detection of emotional stimuli and others have changed over time. Even though no new, added structures are present in the human brain compared to nonhuman primates, evolution tweaks existing structural systems with possible functional implications. Empirical comparative neuroanatomical evidence (...) is presented here in support of such changes in the limbic system, including the amygdala and the orbitofrontal cortex. Given their possible functional significance, these alterations may further enable and enhance human interest and motivation to communicate beyond what is seen in other primates living in complex social groups. The argument here is that even though emotion processing is likely needed for increased social complexity independent of language, the reason why humans want to talk may be related in part to the enhancement of socioemotional processes resulting from the reorganization and rewiring of underlying neural systems some of which are interconnected to the language areas. Neurodevelopmental disorders in humans affecting both language and sociability fuel such arguments. (shrink)
