Explores the understanding of self-consciousness and personal identity - two fundamendtal features of human subjectivity - as it developed in early modern philosophy. Udo Thiel presents a critical evaluation of these features as they were conceived in the sevententh and eighteenth centuries. He explains the arguments of thinkers such as Descartes, Locke, Leibniz, Wolff, and Hume, as well as their early critics, followers, and other philosophical contemporaries, and situates them within their historical contexts. Interest in the issues of self-consciousness and (...) personal identity is in many ways characteristic [of] and even central to early modern thought, but Thiel argues here that this is also an interest that continues to this day, in a form still strongly influenced by the conceptual frameworks of early modern thought. In this book he attempts to broaden the scope of the treatment of these issues considerably, covering more than a hundred years of philosophical debate in France, Britain, and Germany while remaining attentive to the details of the arguments under scrutiny and discussing alternative interpretations in many cases"--Publisher's description, p.

Studies in experimental philosophy claim to document intuition variation. Some studies focus on demographic group-variation; Colaçoet al., for example, claim that age generates intuition variation regarding knowledge attribution in a fake-barn scenario. Other studies claim to show intuition variation when comparing the intuition of philosophers to that of non-philosophers. The main focus has been on documenting intuition variation rather than uncovering what underlying factor(s) may prompt such a phenomenon. We explore a number of suggested explanatory hypotheses put forth by Colaçoet (...) al., as well as an attempt to test Sosa's claim that intuition variance is a result of people ‘filling in the details’ of a thought experiment differently from one another. We show (i) that people respond consistently across conditions aimed at ‘filling in the details’ of thought experiments, (ii) that risk attitude does not seem relevant to knowledge ascription, (iii) that people's knowledge ascriptions do not vary due to views about defeasibility of knowledge. Yet, (iv) we find no grounds to reject that a large proportion of people appear to adhere to so-called subjectivism about knowledge, which may explain why they generally have intuitions about the fake-barn scenario that vary from those of philosophers.

We prove a topological completeness theorem for infinitary geometric theories with respect to sheaf models. The theorem extends a classical result of Makkai and Reyes, stating that any topos with enough points has an open spatial cover. We show that one can achieve in addition that the cover is connected and locally connected.

PurposeThe paper aims to explore future and emerging information and communication technologies. It gives a general overview of the social consequences and ethical issues arising from technologies that can currently be reasonably expected. This overview is used to present recommendations and integrate these in a framework of responsible innovation.Design/methodology/approachThe identification of emerging ICTs and their ethical consequences is based on the review and analysis if several different bodies of literature. The individual features of the ICTs and the ethical issues identified (...) this way are then aggregated and analysed.FindingsThe paper outlines the 11 ICTs identified. Some of the shared features that are likely to have social relevance include an increase in natural interaction, the invisibility of technology, direct links between humans and technology, detailed models and data of humans and an increasing autonomy of technology that may lead to power over the user. Ethical issues include several current topics such as privacy, data protection, intellectual property and digital divides. New problems may include changes to the way humans are perceived and the role of humans and technology in society. This includes changing power structures and different ways of treating humans.Research limitations/implicationsThe paper presents a piece of foresight research which cannot claim exact knowledge of the future. However, by developing a detailed understanding of possible futures it provides an important basis for current decisions relating to future technology development and governance.Practical implicationsThe paper spells out a range of recommendations for both policy makers and researchers/industry. These refer to the framework within which technology is developed and how such a framework could be designed to allow the development of ethical reflexivity.Social implicationsThe work described here is likely to influence EU policy on ICT research and technology research and innovation more broadly. This may have implications for the type of technologies funded and broad implications for the social use of emerging technologies.Originality/valueThe paper presents a novel and important broad view of the future of ICTs that is required in order to inform current policy decisions.

The interview was conducted in September 1996 in Cambridge. Marilyn Strathern (MS) and Janet Carsten (JC) had been colleagues at the University of Manchester’s Department of Social Anthropology until September 1993, when Marilyn Strathern left to take up the William Wyse Professorship at the University of Cambridge, where she remained until retirement in 2008. Janet Carsten joined Edinburgh in October of the same year, where she is presently Professor of Social and Cultural Anthropology. (Supplementary questions, reflecting back on (...) the earlier interview, were put to Marilyn Strathern by the editors of the special issue in 2013.). (shrink)

Self-fulfillment of theories is argued to be a threat to social science in at least two ways. First, a realist might worry that self-fulfillment constitutes a threat to the idea that social science is a proper science consistent with a realist approach that develops true and successful statements about the world. Second, one might argue that the potential self-fulfilling nature of social science theories potentially undermines the ethical integrity of social scientists. We argue that if one accepts that social science (...) theories are not based on laws akin to those that govern natural reality or acknowledges that if one can predict self-fulfillment via a meta-theory that explains the underlying regularities of the self-fulfilling change, the threat to realism is dismantled. Furthermore, on the basis of these arguments, we show that if one is unable to predict the consequences of a theory, it is difficult to ascribe moral responsibility at the individual level. It is, therefore, not the potential self-fulfillment of theories per se that poses an ethical challenge, in contrast to claims in the literature. (shrink)

The present study of sense and reference in the logic of Frege represents the first fruits of several years of dealing with the work of this great German logician. In the preparation of this work, which was presented as a dissertation to the Faculty of Philosophy of the Friedrich-Alexander University in Erlangen/Nuremberg, assistance came from many quarters. lowe most to Professor R. Zocher, who directed this dissertation with understanding counsel and unflagging interest. I must also thank Professor P. Lorenzen, whose (...) courses and seminars provided more inspiration than might be immediately apparent in the book. Professor W. Britzelmayr of Munich was so kind as to provide copies of important fragments of Frege's works. These texts are reproduced with the permission of Professor H. Hermes, Director of the 'Institut fUr mathematische Logik und Grund lagenforschung' in Munster, where Frege's works and letters are being prepared for publication. The preparation of this work was greatly facilitated by a two-year grant from the Fritz Thyssen Foundation. CHRISTIAN THIEL Nuremberg, February 1965 v TRANSLATOR'S NOTE In the difficult matter of Fregean terminology we have taken Ignacio Angelelli's translation of Two Soviet Studies on Frege as the model. Both Professor Angelelli and Dr. Thiel have been so kind as to read over the translation before publication. (shrink)

On 5 May 1957, Leopold Löwenheim passed away in a Berlin hospital following a short but severe illness, unnoticed by the community of mathematical logicians who believed that he had perished in a Nazi concentration camp in or shortly after 1940 (the year of publication in the Journal of Symbolic Logic of his last paper before the end of World War II). The 50th anniversary of his death seems an appropriate date for the posthumous publication of a paper that was (...) supposed to appear in Fundamenta Mathematicae in 1939, the galley proofs of which Löwenheim had already seen and corrected when German troops invaded Poland on 1 September 1939. Löwenheim managed to save the proofs through the War, despite the loss of most of his possessions during the bombing of Berlin in 1943 and 1944. By another lucky chance, a copy of the proofs survived in the present author's possession, when the originals were lost during a flat clearing in Berlin as part of the estate of Johannes Teichert (1904?1994), Löwenheim's step-son, when his widow moved into a nursing-home in May 1999. Later, I will expand these short remarks slightly but seize the present opportunity to resume (and in some places add to) the extant data on Löwenheim's life and writings. (shrink)

In 1783 John Michell published a note entitled ‘On the Means of Discovering the Distance, Magnitude etc. of the Fixed Stars, in Consequence of the Diminution of the Velocity of their Light’, but it was Christian Doppler who in 1842 for the first time formulated the principle : If a source of sound or light is in motion relative to an observer, or an observer in motion relative to a source, the period of the waves received by the observer will (...) be different from the period of the waves emitted by the source. The acoustical Doppler principle was verified in 1845 by Buys-Ballot's experiments and by Ernst Mach ). H. Fizeau proposed to verify the optical Doppler principle by measuring the shift of lines in the spectra of stars . This was carried out by William Huggins , and H. C. Vogel and led to exact results in 1892. The Doppler effect with canal rays was shown by Johannes Stark in 1905. (shrink)

The notion of testifying (or testimony) is the central notion of Bolzano's theory of communication. In his Wissenschaftslehre (Theory of Science) Bolzano gives an analysis of this notion. It shows surprising parallels to Paul Grice's attempt to define "A meantNN something by x". I will begin with an explanation of some parts of the analysis and continue with an investigation of the relationship between Bolzano's analysis and that of Grice. In conclusion I would like to present some evidence supporting the (...) hypothesis that several of the virtues of Grice's theory had already been developed by Bolzano, whose approach even has the advantage of a better definition than Grice's, as Bolzano's analysis provides a better basis for defining a notion of successful communication of information.

Research methods and their developers play a crucial role in bringing together scientific fields. Scientists, who wish to have their methods acknowledged and used in another discipline have to bridge the gaps between different practices and worldviews, and they often experience hostility, incredulity, and in general feelings of ‘otherness’, while changing the established practice in a scientific field. Researchers representing newly emerging fields such as materials science have to overcome obstacles that are caused more by feelings of threat and fear (...) than by arguments rooted in epistemic or social considerations. In using the habitus concept of Pierre Bourdieu, I analyze in this article statements and observations of the scientists who in the 1950s and 1960s have introduced physical methods into chemistry and in so doing merged characteristic features of research communities into a new unit. The habitus of physicists, chemists and method-oriented researchers are shaped by hierarchical relationships inside the disciplines, and between them. Studying emotional expressions in interviews and self-descriptions gives access to hitherto neglected parts of the historical processes leading to new disciplines and fields. The brief case studies presented are seen as exemplars, and the analysis offered is intended more to provide a possible model for further research than as giving conclusive answers. (shrink)

The linkages and interactions of scientific disciplines with industry, politics, and society have long been a staple in the history of science, the history of technology, and science studies. However, it is arguable that the impact of this intertwining on the epistemic and social core of scientific disciplines has not yet been sufficiently explored. Chemistry is an ideal case in point, given that it has emerged as one of the largest scientific disciplines while at the same time becoming one of (...) the world’s most powerful technologies. Specifically, chemistry’s power lies in its ability to gain knowledge of the natural world by transforming it, along with the society in which it is embedded. The four contributions to this Focus section all address chemistry’s border permeability, based on its transformative powers; they focus on the feedback mechanisms that transformed chemistry and thereby altered the very concept of a scientific discipline. So successful has this “nonclassical approach” become that, in the opinion of the contributors to this Focus section, it is now both necessary and advisable to study the history of chemistry’s embeddedness and power in science and technology.

By a classifying topos for a first-order theory , we mean a topos such that, for any topos models of in correspond exactly to open geometric morphisms → . We show that not every first-order theory has a classifying topos in this sense, but we characterize those which do by an appropriate ‘smallness condition’, and we show that every Grothendieck topos arises as the classifying topos of such a theory. We also show that every first-order theory has a conservative extension (...) to one which possesses a classifying topos, and we obtain a Heyting-valued completeness theorem for infinitary first-order logic.

By bringing feminist science studies scholar Donna J. Haraway’s A manifesto for cyborgs (1985) and Situated knowledges (1988) in line with contemporary critical new materialist thought (see Colman & Van der Tuin, 2024; Dolphijn & Van der Tuin, 2012; Geerts, 2022), this critical pedagogical and philosophical think piece tackles the problematic of Anthropocenic disruptions of the planetary biosphere for critical pedagogies and higher education (also see Carstens, 2016). It additionally encourages its readers to think through their own pedagogical conceptions and (...) praxes by means of irruptive (Geerts & Carstens, 2024; Koro-Ljungberg, 2015) selfreflection- stimulating questions. Our situated – and thus limited and open-ended – response to this all-encompassing Anthropocenic crisis is rooted in a rethinking of Harawayan cyborgian and situated knowledges and the critical pedagogical lessons drawn from the latter. Rereading Haraway’s work through contemporary critical new materialist and related scholarship reveals that it already contained an ecofeminist onto-epistemological shift toward more-than-human agency and relationality. This shift has major consequences for all things critical pedagogical and educational, as our pedagogical thinking-doings are deeply embedded in today’s crisis-ridden lifeworld. This rereading exercise furthermore underlines the necessity of an updated critical new materialist pedagogical praxis for learning and teaching, inspired by Harawayan ecofeminism, that takes the entanglements between human, dehumanised, and more-than-human actors seriously.

: This article addresses the fact of possible and impossible determination of the I or the self-reflective I. In this context, two questions in particular are discussed: What epistemic functions of the I can be legitimately identified, and what kinds of determination of the I are invalid? A theoretical proof of the immortality of a single, persistent substance of the soul is not possible, because no material substance that corresponds to the I can be found or determined. As this article (...) shows, however, at least a specific form of knowledge of the I, with a view to Kant’s unity of apperception and its actions, can be observed and is therefore epistemically justified.

Antecedent-strengthening, a trivially valid inference of classical logic of the form: P → Q ⊨ → Q, has a counterpart in everyday reasoning that often fails. A plausible solution to the problem involves assuming an implicit ceteris paribus qualifier that can be explicated as an additional conjunct in the antecedent of the premise. The qualifier can be explicated as ‘everything else relevant remains unchanged’ or alternatively as ‘nothing interferes’. The qualifier appears most prominently in the context of the discussion of (...) laws in the sciences, where these laws are often expressed with a CP qualifier. From an analysis of the qualifier’s role in the problem of antecedent-strengthening, we can learn more about CP qualifiers in general and in their application to the laws used in the sciences.

The different versions of the Kochen-Specker Theorem show that quantum mechanics cannot be supplemented by hidden variables given two constraints. These results are generally interpreted as showing that QM is complete in the following way. A QM system S has only those values of observables for which the state yields probability 1. For all other probabilities S adopts a value during the measurement interaction. But this interpretation is fundamentally problematic. In fact it cannot yield a general and coherent interpretation of (...) the trace formula. I present an argument to this effect, discuss a possible objection and sketch implications. (shrink)
