We examine the epistemological foundations of a leading technique in the search for evidence of life on exosolar planets. Specifically, we consider the “transit method” for spectroscopic analysis of exoplanet atmospheres, and the practice of treating anomalous chemical compositions of the atmospheres of exosolar planets as indicators of the potential presence of life. We propose a methodology for ranking the anomalousness of atmospheres that uses the mathematical apparatus of support vector machines, and which aims to be agnostic with (...) respect to the particular chemical biosignatures of life. We argue that our approach is justified by an appeal to the “hinge” model of epistemic justification first proposed by as reported by Wittgenstein. We then compare our approach to previous work due to Walker et al. :779–824, 2018) and Cleland :722–729, 2019a; Does ‘life’ have a definition?, Cambridge University Press, New York, 2019b). (shrink)

This paper describes a now widely forgotten tradition in the nineteenth century which - to borrow a simile used or implied by the actors themselves - may be described as 'spectroscopic portraiture'. Quite unlike the later obsession with numerical precision in wavelength measurement, and also in stark contrast to the contemporary vogue of photographic mapping which presumptuously claimed 'mechanical objectivity', that is avoidance of any human intervention in the recorded data, there was among some spectroscopists a much greater preoccupation (...) with qualitative rather than quantitative aspects. The atlases of the solar spectrum by Cornu, Thollon, and Piazzi Smyth were supposed to convey the subjectively perceived Gestalt of the Fraunhofer lines, at the expense of precision. I shall argue that this was a systematic research programme addressed to a welldefined but small audience of specialists in the new subdiscipline of spectroscopy which was distinct from other practices such as spectrum analysis, which was directed mainly at chemists. Apart from this, the new tradition can also be identified by the dense net of cross-references in the publications of the various members, and by their critique of earlier work. This tradition of spectrum portraiture started with Kirchhoff's 1861-2 high-resolution chromolithographic plates of the solar spectrum, which were printed off a half-dozen different stones in order to render most faithfully the various line intensities. Focusing especially on the tension between representational goals and technical possibilities in the rapidly developing printing industry, I then trace the emerging tradition through its apogee to the close of the nineteenth century.

Young netizens are an emerging generator of online content, engaging in an increasing number of online flaming interactions. This shortened communication mode has incorporated power amplifiers, enabling the inclusion of both verbal and non-verbal triggers, thereby initiating abuses akin to cyberbullying. Cyberbullying has emerged as an extremely unstable hot issue, which is difficult to regulate upstream, severely impacting inexperienced young netizens. This Machiavellian apparatus proves to be sophisticated, given its powerful nature, and results in its victims being ensnared in (...) a cyber net from which they see very little escape. Laws have been enacted to combat cyberbullying, which is rampant among netizens, highly naive or actively aggressive in their use of various social media platforms. (shrink)

What is an apparatus? -- The friend -- What is the contemporary?

The work of Michel Foucault is not often considered in animal ethics discussions, but I believe that many of his insights can be fruitfully extended into this area of philosophical inquiry. In this paper, I present the slaughterhouse as a technology of power that is complicit in the domination and objectification of both human and nonhuman animal subjects. I begin by arguing that Foucault’s notion of an “apparatus” is a useful methodological tool for thinking about the constellation of spaces (...) and discourses in which various bodies (both human and nonhuman) find themselves enmeshed. Next, I outline Foucault’s multifaceted conceptualization of “power,” and I consider whether it makes sense to think of other animals as implicated in “power relations” in the various Foucauldian senses. Finally, I analyze a journalistic account of a contemporary slaughterhouse. Here, I argue that a variety of hierarchies (spatial, racial, species, etc.) dovetail to create an environment in which care and concern are virtually impossible. By coupling a Foucauldian analysis with certain insights developed in the bioethical work of Ralph Acampora, I offer a normative critique of an institution that has pernicious effects on both human and nonhuman animals.

The apparatus theory is used to challenge the interpretation of religion and also to determine whether religion is a factor to contend with in modern society. Religion could be the element that keeps the city intact or could be the one element that is busy ruining our understanding of reality and the way this interacts with society in the urban environment. Paradigms determine our relationships. In this case, the apparatus theory would be a more precise way of describing (...) not only our relationship towards the city but also the way in which we try to perceive our relationship with religion and the urban conditions we live in. This article gives theoretical background to the interpretation and understanding of the relationship between various entities within the city. The apparatus of the city creates space for religion to function as a binding form. Religion could bind different cultures, diverse backgrounds and create space for growth. (shrink)

The book includes many seminal articles by film scholars such as Christian Metz, Jean-Louis Baudry, Stephen Heath, Peter Wollen, Laura Mulvey, and Noel Burch, and by the era's leading cultural thinkers as well: Roland Barthes, Julia ...

In this paper I argue that demonstrative induction can deal with the problem ofthe underdetermination of theory by evidence. I present the historical case studyof spectroscopy in the early 1920s, where the choice among different theorieswas apparently underdetermined by spectroscopic evidence concerning the alkalidoublets and their anomalous Zeeman effect. By casting this historical episodewithin the methodological framework of demonstrative induction, the localunderdetermination among Bohr's, Heisenberg's, and Pauli's rival theories isresolved in favour of Pauli's theory of the electron's spin.

Abstract and Keywords Mainstream philosophers take for granted that disability is a prediscursive, transcultural, and transhistorical disadvantage, an objective human defect or characteristic that ought to be prevented, corrected, eliminated, or cured. That these assumptions are contestable, that it might be the case that disability is a historically and culturally specific, contingent social phenomenon, a complex apparatus of power, rather than a natural attribute or property that certain people possess, is not considered, let alone seriously entertained. This chapter draws (...) on the insights of Michel Foucault to advance a historicist and relativist conception of disability as an apparatus (dispositif) of power and identify mechanisms of power within philosophy that produce the underrepresentation of disabled philosophers in the profession and the marginalization of philosophy of disability in the discipline. -/- Keywords: disability, Michel Foucault, apparatus, historicist, relativist, underrepresentation of disabled philosophers.
