This thesis investigates the metaphysical nature of necessity. My study focuses primarily on the reduction of metaphysical necessity and the question of whether a necessary truth can be reductively defined. Theodore Sider develops a new reductive account of metaphysical necessity. Unfortunately, the multiple realizability problem posed by Jonathan Schaffer undermines the credibility of Sider’s account. This underlies my motivation to search for a revised Siderian account of necessity. On this basis, I propose a modified version of Sider’s account and argue (...) that analytic, natural-kind and micro-reduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Since logical truths are necessary truths, analytic, natural-kind and micro-reduction truths are necessary truths as well. In this thesis, I will proceed as follows. Chapter 1 introduces Sider’s account of necessity. In particular, I focus on his analysis of the necessity of a micro-reduction truth. His analysis is largely constitutive of the notion of a metaphysical semantics and some associated notions. I reconstruct his analysis and articulate his metaphysical semantics and the associated notions. Chapter 2 presents and clarifies the multiple realizability problem of Schaffer. His critique shows that Sider’s metaphysical semantics cannot handle multiple realizability. Sider refutes this claim by arguing that the multiple realizability problem is a problem for his analysis of the necessity of a micro-reduction truth, not for his metaphysical semantics itself. This is a good starting point to propound a modified account of necessity. Chapter 3 proposes and articulates my modified analysis of the necessity of a micro-reduction, where I show that the necessity of a micro-reduction truth can be reductively defined without appeal to Sider’s metaphysical semantics. I argue that analytic, natural-kind and microreduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Logical truths are necessary and so are they. After that, I consider a potential objection to my modified account and attempt to respond to it. (shrink)

In seeking an answer to the question of what it means for a theory to be fundamental, it is enlightening to ask why the current best theories of physics are not generally believed to be fundamental. This reveals a set of conditions that a theory of physics must satisfy in order to be considered fundamental. Physics aspires to describe ever deeper levels of reality, which may be without end. Ultimately, at any stage we may not be able to tell whether (...) we've reached rock bottom, or even if there is a base level – nevertheless, I draft a checklist to help us identify when to stop digging, in the case where we may have reached a candidate for a final theory. Given that the list is – according to (current) mainstream belief in high-energy physics – complete, and each criterion well-motivated, I argue that a physical theory that satisfies all the criteria can be assumed to be fundamental in the absence of evidence to the contrary (i.e., I argue that the necessary conditions are jointly sufficient for a claim of fundamentality in physics).

Many philosophers insist that the most plausible solution to the exclusion problem is to adopt the so-called ‘autonomy approach’, which denies either upward or downward causation between mental and physical properties. But the question of whether the autonomy approach is compatible with respectable theories of causation has seldom been discussed in the literature. This paper considers two influential theories of causation, the counterfactual account and the regularity account. I argue that neither the counterfactual theory nor the regularity theory can support (...) the autonomy approach – while the counterfactual approach fails to block downward causation, the regularity approach is unable to refute upward causation.

This essay provides a theoretical and methodological introduction to the writings of Vinciane Despret. Over the last twenty years Despret has contributed a significant number of books and articles in the fields of philosophical ethology and animal studies, and throughout them all Despret's methodological approach resists easy explanation. There is no single, uni- versal method applicable to all animals, in every situation; instead, Despret responds with an open curiosity to the plurality of animal worlds and the storied versions about them. (...) She studies and works with animals just as much as with scientists, farmers, and conserva- tionists. Taking joy in the diversity of animal behaviour, she creates conditions that allow animals to be interesting, and finds humour, warmth, and care in the stories that they tell. Through the practices of human–animal relations Despret contends that humans are transformed, in their thought just as much as in their practices, as much as animals are transformed. This ess..

The concept of `the granny' is not uncommon in British media texts, in a range of stereotyped representations of older women and in (sometimes playful, sometimes serious) invocations of the grandmother role. `Granny parties' are one genre of recreational social event where young people dress up as grannies. In this paper I bring together data from the media and from an ethnographic study of granny parties in order to assess the age-political and ideological significance of `granny' in these very different (...) contexts. In both cases, representations and performances prove to be fashioned dialectically, in relation to normative assumptions about grannies as conservative, passive and out-dated characters. Despite the ludic frames of many representations, it isargued that the granny concept recycles restrictive ideological values for gendered ageing. (shrink)

If we define tradition too hastily we leave to one side the question of what the relevance of tradition is for us. Here the concept of tradition is opened up by considering the different views of it taken by Hannah Arendt, Michael Oakeshott and Alasdair MacIntyre. We see that each has put tradition into a fully developed picture of what our predicament is in modernity; and that each has differed in their assessment of what our relation to tradition is or (...) should be. Arendt sees tradition as something which no longer conditions action, Oakeshott sees tradition as something which conditions all action, and MacIntyre sees tradition as something which should condition right action. In each case, the view of tradition is clearly one element in an attempt to see how the most important constituent elements of human existence – variously called the human condition, human conduct, or human virtue – should be understood in a modernity which is ours because it has put the traditional concept of tradition into question.

In his excellent book World without Design, Michael Rea argues that naturalism is not a philosophical thesis but a research program. I believe that there is good reason to question Rea’s claim about naturalism. In this brief paper, I critique Rea’s argument and defend a particular understanding of naturalism as a philosophical thesis.

The posthuman is a multidimensionally hybrid figure: it denotes both the post-biological or technological being that mostly inhabits science-fiction stories as well as the ensuing reconceptualisation of what it means to be human. Even within these conditions, it remains hybrid: posthuman beings are mixes of organic and non- organic materials while posthuman conceptualisations combine philosophical and technological perspectives. This dissertation claims that the profoundly hybrid nature of the posthuman forces its texts – whether fictional or theoretical – to adopt similarly (...) hybrid statuses. More concretely, on the one hand, its fictional nature forces the presence of fiction into theoretical texts, which mainly materialises intertextually. On the other hand, the posthuman’s philosophical extent as well as its hybridity as a being make it highly probable for theory and philosophy to manifest in posthuman-featuring fiction. This last phenomenon – which will be the focus of my presentation - may operate through three mechanisms: intertextuality, where theories of the posthuman are referred to in fiction; reflexive discourse, where philosophical reflection or theoretical content are conveyed by various narrative devices indirect speech, amongst others); and double referentiality, where philosophical reflection emerges out of the science-fictional juxtaposition of a cognitively estranging world with the actual world. The dissertation exemplifies the first aspect with the Japanese anime Ghost in the Shell 2 and the Belgian play Cocon!, which both feature characters named Haraway. The second and third aspects are described through the analysis of three novels: LoveStar by Andri Snær Magnason, The Possibility of and Island by Michel Houellebecq and Oryx and Crake, by Margaret Atwood.

In this paper, I will defend an alternative account of disposition ascriptions influenced by considerations from possible worlds semantics for modals according to which disposition ascriptions express modals relations characterized by a particular restriction on accessible worlds. My focus will be on the "modal problem" for disposition ascriptions (precisely what kind of modality do these claims express?), and the approach I adopt reflects this starting point. Most analyses – like the Simple Conditional Analysis – have explained disposition ascriptions by suggesting (...) schematic truth-conditional equivalences with other modal claims in English. This only indirectly addresses the modal problem – for instance by first drawing a truth conditional equivalence between disposition ascriptions and counterfactuals and then explaining the modal relation expressed by counterfactuals. I will try to give a ‘direct’ answer to the modal question -- that is, to analyse disposition ascriptions in a general possible worlds framework in which we can compare the analysis to actual and possible analyses for other modals – in particular, counterfactuals. The framework I’ll use is a simple version of Angelika Kratzer’s relational analysis of modals. I'll focus on two problems that nicely connect the dispositional and the modal – (a) the challenge of purportedly ‘extrinsic dispositions,’ and (b) the problem of the "granularity" of possibilities we’re quantifying over (are they situation- or world-sized?).

Feminist philosophers of technoscience have long argued that it is vital that we question biomedical and scientific claims to an immaterial and disembodied objectivity, and also, more specifically, that we disable the conception of medical visualising technologies as neutral or transparent conduits to the “fact” of the body. In this paper we suggest that corporeal feminism is well situated to provide such a critique. Feminist phenomenologists over the past decade have theorised embodiment in a number of critical ways, many deriving (...) concepts from the work of Merleau-Ponty, and emphasising the pliability and diversity of our body images and corporeal schematics. Others such as Elizabeth Wilson, Cathy Waldby and Drew Leder have considered the interdependence of our inner biology or viscerality with the socio-cultural inscriptions of embodiment. In this paper, these adaptations of phenomenology, and their account of the specificity and depth of embodied being, will be discussed and applied to the discourse of biomedicine and the apparatus of magnetic resonance imaging (MRI).

Hypersequents are a natural generalization of ordinary sequents which turn out to be a very suitable tool for presenting cut-free Gentzent-type formulations for diverse logics. In this paper, an alternative way of formulating hypersequent calculi (by introducing meta-variables for formulas, sequents and hypersequents in the object language) is presented. A suitable category of hypersequent calculi with their morphisms is defined and both types of fibring (constrained and unconstrained) are introduced. The introduced morphisms induce a novel notion of translation between logics (...) which preserves metaproperties in a strong sense. Finally, some preservation features are explored. (shrink)

This thesis philosophically examines, critically discusses, and proposes how a plausible philosophical framework of consciousness and free will should be formulated. This framework takes into account contemporary scientific research on human consciousness and free will and its possible challenges; also it is examined how this framework should be related to theistic beliefs – especially those connected to human and divine consciousness and free will. First, an overview of important research within the natural sciences about the conscious mind is presented together (...) with its challenges to a theistic worldview. Next, questions related to reductive physicalism and dualism as a thesis and an antithesis are discussed. This dialectical approach leads to two lines for possible alternatives: emergence theories and process panpsychism. The subsequent analysis suggests that a form of process panpsychism in combination with a weaker form of emergence is most plausible. After a discussion of some central ideas about determinism and indeterminism, together with a brief overview of standard arguments within the philosophical free will debate, the proposed emergent process panpsychism is related to these standard arguments in the free will debate and scientific research about decision-making. As a result it will be suggested how free will should be understood in relation to the emergent process panpsychism. The consequences of these results are then discussed in relation to a theistic worldview. Here panentheism will be suggested as the most reasonable conception of God. Also, the consequences for divine consciousness, divine action and interaction, the human soul, life before birth and after death, and more briefly a personal relationship with God, theological determinism, omniscience, and omnipotence will be discussed specifically in relation to panentheism in an emergent process panpsychist setting.

This article is an ethnographic account of the speculative thought of Jane Roberts, a spirit medium or “channel,” important in New Age religion for the books that she dictated at the behest of a personality named “Seth.” At first, she tried to understand her strange subjectivity in psychiatric terms, then went on to elaborate metaphysical concepts to account for it. The author argues that understanding Roberts's concepts in social historical terms risks obscuring their meaning and that comparing them with the (...) related concepts of a credentialed philosopher, in this case Gilles Deleuze, is a more effective way of approaching them. The latter sort of interpretation entails another risk, however, which is that concepts like those of Roberts may get taken for mere illustrations of the arguments made by academic philosophers, whereas marginal thinking of Roberts's kind can form sophisticated bodies of thought on their own. Roberts developed concepts of consciousness and the person that exceed, in ways that this article specifies, anything that Deleuze's work can say about them and thus cast his own arguments in an unanticipated light. This essay's main point is that uncredentialed, marginal thinkers like Roberts should be considered proper objects of both anthropological and philosophical study and should be taken seriously for what they can teach us.

In this paper, I wish to challenge theory-biased approaches to scientific knowledge, by arguing for a study of theorizing, as a cognitive activity, rather than of theories, as abstract structures independent from the agents’ understanding of them. Such a study implies taking into account scientists’ reasoning processes, and their representational practices. Here, I analyze the representational practices of geneticists in the 1910s, as a means of shedding light on the content of classical genetics. Most philosophical accounts of classical genetics fail (...) to distinguish between the purely genetic, or Mendelian level, and the cytological one. I distinguish between them by characterizing them in terms of their respective associated representational practices. I then present how the two levels were articulated within Morgan’s theory of crossing-over, and I describe the representational technique of linkage mapping, which embodies the “merging” of the Mendelian and cytological levels. I propose an analysis of the mapping scheme, as a means of enlightening the conceptual articulation of Mendelian and cytological hypotheses within classical genetics. Finally, I present the respective views of three opponents to Morgan in the 1910s, who had a different understanding of the articulation of cytology and Mendelism, and entertained different views concerning the role and proper interpretation of maps. I propose to consider these diverging perspectives as instantiating what I call different “versions” of classical genetics. (shrink)
