In September 1999 "Nature" magazine announced that atomic orbitals were di-rectly observed. Opposing it, Eric Scerri, editor-in-chief of "Foundations of Chemistry", claimed that what could be observed in the experiment was electron density, not orbitals. The main purpose of this paper is to consider philosophical and methodological aspects of the above controversy. Especially, the problems of direct observability and reality of theoretical entities are taken under detailed discussion. From the point of view of quantum mechanics there are not any reasons (...) to believe that orbitals exist. However, realistically treated orbitals are very effective tools in the laboratory practice of chemistry. (shrink)

The paper is focused on some aspects of experimental realism of Ian Hacking, and especially on his manipulability criterion of existence. The problem is here related to chemical molecules, the objects of interest in chemical research. The authors consider whether and to what extent this criterion has been applied in experimental practice of chemistry. They argue that experimentation on is a fundamental criterion of existence of entities in chemistry rather than experimentation with. Some examples regarding studies of structures of complex (...) compounds, taken from organic chemistry, are presented to support the authors' considerations. Chemists' laboratory practice depends strongly on the way that representations of entities on (or with) the experiments are used. The authors show that this point has not been given sufficient attention by the new experimentalists. (shrink)

Wśród filozofów nauki panuje rozpowszechnione przekonanie, że spór o realizm nie wpływa w sposób istotny na praktykę badawczą nauk przyrodniczych, a postawa realistyczna jest naturalnym stanowiskiem epistemologicznym przyjmowanym przez przyrodników. W artykule podana jest argumentacja na rzecz tezy, że w naukach przyrodniczych są formułowane koncepcje teoretyczne, które wywołują wśród uczonych istotne kontrowersje poznawcze, które nie pozostają bez wpływu na ich praktykę badawczą. Rozważona zostanie teza Gastona Bachelarda, że przezwyciężenie przez daną dziedzinę nauki realistycznego ‘obciążenia’ jej aparatu konceptualnego ma istotny wpływ (...) na jej rozwój. Prowadzone rozważania będą opierały się na analizie przykładów wziętych z praktyki badawczej chemii XIX i początku XX wieku, w której dyskutowano problem statusu poznawczego przekonań, dotyczących istnienia odniesień przedmiotowych takich pojęć, jak: atom, wzór strukturalny czy wiązanie chemiczne.

The paper is focused on the role of philosophy of chemistry in the philosophy of natural sciences. The author claims that chemistry is a paradigmatic example of laboratory science in Ian Hacking’s sense. Therefore a philosophical and methodological analysis of chemistry can change or modify several theses of the philosophy of natural sciences. Some of them are as follows: the stability of laboratory science; the primacy of experimental practice over the theoretical one in chemistry; the problem of the reduction of (...) chemistry to physics; the influence of scientific instruments on the growth of chemical knowledge; the problem of the empirical criteria of the existence of theoretical entities; the role of theoretical models and theoretical modelling in laboratory sciences; the problem of using the principle of inter- subjective testability in chemistry; the semiotic peculiarities of chemistry.

The main aim of this paper is to present the motivation of the thesis that theoretical models con not fulfill the function of representation. The author analyses examples of such models used in molecular quantum mechanics.

In the paper entitled “Scientific Explanation and Metaphor” Jerzy Kmita divided all metaphors on reporting and explicative ones. He assumed that the explicative metaphors could play a cognitive function in science, and also characterized them according to Max Black’s interactive theory of metaphor. The main purpose of my paper is to analyse Kmita’s explicative conception of metaphor in the view of Lakoff & Johnson’s cognitive theory of metaphor. I attempt to show that metaphors play an important role in a process (...) of making knowledge, especially in a conceptualization of domain being studied. In spite of an interactive account of metaphor I claim that making use of a metaphor is a process, which proceeds only in the one direction. In the last section of the paper I briefly analyse a few examples of metaphors used in natural sciences. (shrink)

REVERE Award Finalist, PreK-12 Learning Group, Association of American Publishers! " Functional scientific literacy requires an understanding of the nature of science and the skills necessary to think both scientifically and ethically about everyday issues." -- from the introduction to It's Debatable! This book encourages scientific literacy by showing you how to teach the understanding and thinking skills your students need to explore real-world questions like these: - Should schools charge a "tax" to discourage kids from eating unhealthy foods? - (...) Should local governments lower speed limits to reduce traffic fatalities? - Should pharmaceutical companies be allowed to advertise prescription drugs directly to consumers? At the core of the exploration is the Socioscientific Issues Framework. The framework gives students practice in the research, analysis, and argumentation necessary to grapple with difficult questions and build scientific literacy. After introducing the concept of the framework and explaining how it aligns with the Next Generation Science Standards, the book shows you how to implement it through seven units targeted to the elementary, middle, and high school levels. You even find out how to develop your own socioscientific issues curriculum. Both practical and content-rich, It's Debatable! doesn't shy away from controversy. Instead, the authors encourage you and your students to confront just how messy the questions raised by science (and pseudoscience) can be. After all, as the authors note, " The only way for our students to be prepared for participation in societal discourse is to have practice in their school years, and what better place than the science classroom?".

The paper discusses the thesis of virtual realism presented by David Chalmers in his paper “The Virtual and the Real” (2017). Here, I suggest an even stronger version of the claim that I call “virtual physicalism”. According to this view, virtual objects are not only real but physical as they are identical to the physical states of computers that run VR software. I suggest that virtual objects should have a similar ontological status to toys—they should be treated as models or (...) simplifications of ordinary objects. Just like toys, virtual objects can sometimes be good enough to be used instead of their ordinary counterparts. In these cases, virtual objects start to be treated as instantiations of the same kind. In the last part of the paper, I use Johan Huizinga’s notion of a “magic circle” to suggest how different objects could be successfully “virtualized”, that is, moved into a digital realm while remaining objects of the same kind as their non-virtual counterparts. I suggest this will happen once virtual reality becomes permanent and causally connected with non-virtual reality. I finish the paper by looking at examples of natural kind objects and individuals, which seem to be the hardest cases for successful virtualization. (shrink)

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

According to the predictive coding theory of cognition , brains are predictive machines that use perception and action to minimize prediction error, i.e. the discrepancy between bottom–up, externally-generated sensory signals and top–down, internally-generated sensory predictions. Many consider PCT to have an explanatory scope that is unparalleled in contemporary cognitive science and see in it a framework that could potentially provide us with a unified account of cognition. It is also commonly assumed that PCT is a representational theory of sorts, in (...) the sense that it postulates that our cognitive contact with the world is mediated by internal representations. However, the exact sense in which PCT is representational remains unclear; neither is it clear that it deserves such status—that is, whether it really invokes structures that are truly and nontrivially representational in nature. In the present article, I argue that the representational pretensions of PCT are completely justified. This is because the theory postulates cognitive structures—namely action-guiding, detachable, structural models that afford representational error detection—that play genuinely representational functions within the cognitive system.

Almost all of the entropy in the universe is in the form of Bekenstein–Hawking (BH) entropy of super-massive black holes. This entropy, if it satisfies Boltzmann’s equation S=logN\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$S=\log \mathcal{N}$$\end{document}, hence represents almost all the accessible phase space of the Universe, somehow associated to objects which themselves fill out a very small fraction of ordinary three-dimensional space. Although time scales are very long, it is believed that black holes will eventually evaporate by (...) emitting Hawking radiation, which is thermal when counted mode by mode. A pure quantum state collapsing to a black hole will hence eventually re-emerge as a state with strictly positive entropy, which constitutes the famous black hole information paradox. Expanding on a remark by Hawking we posit that BH entropy is a thermodynamic entropy, which must be distinguished from information-theoretic entropy. The paradox can then be explained by information return in Hawking radiation. The novel perspective advanced here is that if BH entropy counts the number of accessible physical states in a quantum black hole, then the paradox can be seen as an instance of the fundamental problem of statistical mechanics. We suggest a specific analogy to the increase of the entropy in a solvation process. We further show that the huge phase volume (N\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mathcal{N}$$\end{document}), which must be made available to the universe in a gravitational collapse, cannot originate from the entanglement between ordinary matter and/or radiation inside and outside the black hole. We argue that, instead, the quantum degrees of freedom of the gravitational field must get activated near the singularity, resulting in a final state of the ‘entangled entanglement’ form involving both matter and gravity.

ABSTRACTThe present study examined relationships between attention to negative words and daily rumination and daily adjustment in a sample of clinically depressed individuals. We recorded eye movements of 43 individuals diagnosed with major depression while they were freely viewing dysphoric, threat-related, neutral, and positive words. Then, each day for one week, participants provided measures of their daily rumination and psychological adjustment. Multilevel analyses found that attention to dysphoric and threat-related words was positively related to daily rumination and attention to threat-related (...) words was negatively related to daily adjustment. These findings suggest that the impaired ability to disengage from negative words is positively related to rumination in daily life and is negatively related to well-being, as defined in terms of Beck’s Triad.

This volume - the first project of its kind in the field - collates c. 1200 biographical entries on Greek sophists and rhetors who flourished in the Roman Empire from the first to the seventh century AD. Ancient Greek sophists, the masters of speech and teachers of rhetoric, constituted one of the most important and interesting intellectual circles of the ancient world. The prosopography provides comprehensive information on sophists and their activities, using abundant and varied source material such as literary (...) texts (including those of the rhetors themselves) and papyrological, epigraphic, and numismatic evidence. Each entry provides data (where available) on sources in which the person is attested, biographical details, career, and rhetorical activity. This book constitutes a basis and a tool for subsequent in-depth studies on the Greek Sophistic movement, as well as a useful reference book for students and all those interested in the culture of the ancient world.

Perspective taking is a critical yet tangled construct that is used to describe a range of psychological processes and that is applied interchangeably with related constructs. The resulting ambiguity is particularly vexing in science education, where although perspective taking is recognized as critical to informed citizens’ ability to negotiate scientifically related societal issues, or socioscientific issues via socioscientific reasoning, the precise nature of perspective taking remains elusive. To operationalize perspective taking, a theoretical conceptual analysis was employed and used to position (...) perspective taking within the context of SSR. The resulting, more precise construct identified as socioscientific perspective taking requires engagement with others or their circumstances, an etic/emic shift in one’s viewpoint, and a moral context guided by conscience.

This paper centers around the notion that internal, mental representations are grounded in structural similarity, i.e., that they are so-called S-representations. We show how S-representations may be causally relevant and argue that they are distinct from mere detectors. First, using the neomechanist theory of explanation and the interventionist account of causal relevance, we provide a precise interpretation of the claim that in S-representations, structural similarity serves as a “fuel of success”, i.e., a relation that is exploitable for the representation using (...) system. Then, we discuss crucial differences between S-representations and indicators or detectors, showing that—contrary to claims made in the literature—there is an important theoretical distinction to be drawn between the two.

In this paper, I identify the hard problem of access for epistemological disjunctivism (ED): given that perceptual experience E is opaque with respect to its own epistemic properties, subject S is not in a position to know epistemic proposition (i) (that E is factive with respect to empirical proposition p) just by having E and/or reflecting on E. This is the case even if (i) is true. I first motivate the hard problem of access (Section 2) and then reconstruct and (...) analyze three of the ways in which EDists have argued for the internal accessibility of the factive character of perceptual experience. These arguments explain internal access in terms of the unity of perceptual and rational capacities (Section 3), favoring support (Section 4), and the outward-looking model of self-knowledge (Section 5). My conclusion (Section 6) is that none of these responses works. I then suggest how ED might be modified to succeed as an access internalist epistemology. (shrink)

LEGO bricks have an enormous educational potential. The article analyzes the possibility of using the bricks in teaching philosophy. As a case in point, it describes the LEGO-LOGOS project, a method where the bricks have been successfully used in opening students to philosophical ideas. The project makes use of play (in this case with the LEGO bricks) to introduce students to philosophy and philosophizing. It tackles one of the biggest obstacles in teaching this subject, that is the resistance of students (...) to formulate and express their thoughts as the method allows for a free and creative expression of ideas and interpretations. The article describes the structure of the classes where the method is to be used and provides an analysis of educational and philosophical assumptions of LEGO-LOGOS also touching on the possibility of using the method as a tool in the school setting and beyond.
