McTaggart’s paradox and his A-theory and B-theory are basic notions in the contemporary philosophy of time. It is well known that the paradox was introduced by McTaggart’s paper called “The Unreality of Time” published in 1908, so that it has a one-hundred-year history. As for A-theory and B-theory, in contrast, McTaggart himself didn’t consider both of them at all. The notions of A-theory and B-theory came much later, 60 years after the paradox. Moreover, they had not been as popularized as (...) they are today until quite recently, at least after the 1990s. This paper aims to trace the origin of the notions of A-theory and B-theory and show how the debates behind them, especially objections to “spatialising time,” form the notions. (shrink)

Monism is a metaphysical view according to which there is only one fundamental object. This paper will explore monism within the context of truthmaker theory, or Truthmaker Monism, a view rarely discussed in literature. Although few truthmaker theorists defend monism, at least explicitly, some theories seem to share the spirit of monism to some extent. Interestingly, they are proposed as solutions for the same problem, called the problem of negative truth. A close examination will show that while each of these (...) solutions can account for the problem, they are unsatisfactory for different reasons. This paper will suggest a novel solution to the problem of negative truth which preserves the advantages of existing solutions while avoiding the difficulties with which they are faced. (shrink)

What is the exact relationship between analytic philosophy and philosophy of science? In this paper, I will address this question from the perspective of research traditions, with the help of recent histor- ical studies on analytic philosophy. The two groups are particularly focused: the Polish philosophers and the logical empiricists in Berlin. Neither of them is unknown to us. However, by taking seriously their connection to the development of analytic philosophy and philosophy of science as research traditions, I believe, the (...) understanding of our own tradition may be improved.

Modal realism is an ontological position made familiar by David Lewis, according to which there exist possible worlds other than the actual world that we inhabit. It is hard to uphold modal realism, and indeed modal realism has only a few advocates. However, as most contemporary metaphysicians agree, this does not mean that it is easy to refute modal realism. In this paper, I argue against modal realism from a metaontological point of view. First, I provide a precise formulation of (...) modal realism based on Lewis’ discussion of modal realism. Second, I argue that modal realism is undermined unless it incorporates a view of metaontology known as ontological realism. Third, I point out that if modal realism incorporates ontological realism, it comes into conflict with its own formulation. (shrink)

Modal realism is an ontological claim according to which there exist many possible worlds just like our actual world. Since it is so hard to believe, modal realism has only a few advocates. However, it is well known that alternative theories have serious problems. It is one of the central issues of metaphysics to find a persuasive way to reject modal realism. In this paper, I will suggest that it could be accomplished with help of metaontology-one of the topics of (...) metaphysics which has recently discussed intensely. I will show how we could argue against modal realism from the metaontological point of view. (shrink)

Since its inception, analytic philosophy has failed to attain dominance in Japan. However, the 21st century has seen analytic philosophy gain traction among Japanese philosophers. This paper, which examines the status quo of analytic philosophy in Japan since 2000, consists of two parts. The first part deals primarily with organizations—specifically, relevant associations, journals, conferences, universities, and publishers are illustrated. The second part explores key works in each area—namely, philosophy of science, philosophy of language, philosophy of logic and mathematics, philosophy of (...) mind, and metaphysics. Key works in other areas are also briefly addressed. (shrink)

In this paper, I try to defend Presentism. First of all, I explore how Presentism diverges to its versions and show that none of them, which include the currently standard Presentism that invokes tense logic, are tenable. Next, I point out that some philosophers argue that by replacing the Quinean criterion of existence with the Truthmaker Principle, another version of Presentism, which invokes tensed properties, can emerges. However, this version has a highly implausible conclusion. Finally, I argue that it can (...) be avoided by taking the evidences of the past or future truths to be typical truthmakers of them.

This article deals with questions that arose during a 2-week university course in nonhuman animal laboratory science. Doctoral students and researchers take the course to acquire the knowledge necessary for future independent work with nonhuman animal experimentation. During the course, participants learn to handle animals in the laboratory, both in theory and in practice, and to do so in a humane way with a feeling for the animals. The paper analyzes how this knowledge, in other tacit contexts, is constructed and (...) learned and focuses on two main aspects of handling rodents in the laboratory: habituation and killing. The course's focus on good handling works as a means of doing good research, as a strategy of including animal welfare as a legitimate agenda, while keeping intact traditional scientific norms—such as standardization. In this case, standardization has a wider scope than commonly assumed: Not only are the animals standardized but also the experimentalists who become standardized through courses and curricula. However, this process of standardization is not complete; thus, a feeling for the animal implies, as the case study shows, individual animal and human-animal interaction. (shrink)

This article addresses the embodied nature of laboratory human—animal practices in order to understand the notions of care that take place within an institution of domination — the apparatus of animal experimentation. How is it possible to both love and harm in this context? Building on animal studies and feminist ethics, the theme of emotionality is explored in the section ‘loving animals’. Here it is demonstrated that empathy and affection for individual animals, as well as species, are strong components of (...) an experimental ethos expressed by the informants. The second empirical section deals with the issue of ‘killing well’. The good kill is supposed to be done with care: quickly and compassionately. This is performed by way of bodily measures of care, technological refinement and personal skills and, sometimes, with the help of a division of labour. In the concluding section, the empirical findings are read through the framework, where the feminist theoretical analysis of love, dependency and care from an embodiment perspective understands the dialectics of instrumentalisation and exploitation of — and care for — animals, not as something that goes on above or outside of relations, but rather as something that can be understood from within. ‘Mortal love’ is the attempt to capture and theorise this dialectic, arguing that emotions of love and friendship are not mere justifications for the harm and killing performed, but rather intrinsic dimensions of the embodied animaling of experimental human—animal relations.

Human/animal relations are potentially controversial and biotechnologically produced animals and animal-like creatures – bio-objects such as transgenics, clones, cybrids and other hybrids – have often created lively political debate since they challenge established social and moral norms. Ethical issues regarding the human/animal relations in biotechnological developments have at times been widely debated in many European countries and beyond. However, the general trend is a move away from parliamentary and public debate towards institutionalized ethics and technified expert panels. We explore by (...) using the conceptual lens of bio-objectification what effects such a move can be said to have. (shrink)

This collected volume of leading specialists in this field offers not only a comprehensive understanding of the medieval concept of nature, but also instructive information for our environment crisis because of continuity and discontinuity between these two ages.

Osmoregulation in insects is an essential process whereby changes in hemolymph osmotic pressure induce the release of diuretic or antidiuretic hormones to recruit individual osmoregulatory responses in a manner that optimizes overall homeostasis. However, the mechanisms by which different osmoregulatory circuits interact with other homeostatic networks to implement the correct homeostatic program remain largely unexplored. Surprisingly, recent advances in insect genetics have revealed several important metabolic functions are regulated by classic osmoregulatory pathways, suggesting that internal cues related to osmotic and (...) metabolic perturbations are integrated by the same hormonal networks. Here, we review our current knowledge on the network mechanisms that underpin systemic osmoregulation and discuss the remarkable parallels between the hormonal networks that regulate body fluid balance and those involved in energy homeostasis to provide a framework for understanding the polymodal optimization of homeostasis in insects.
