Cloning research caught a great deal of attention when Dolly the sheep was born (§4). While some fear surrounded the attainment (§§14-15), Wilmutʼs research itself has grown well, providing a less vicious manner to gain ES cells (§12). In this article, we review the progress of cloning research along with the concern of medical circles about its application to reproductive cloning, that is to say, making replicas of human beings (§§16-21). Note that all the content is ascribed to the author alone, not to Musashino University.

One can work for another person, probably for all the others in an ethical way, and not for money. This is the main idea pursued in this article. When it comes to labour, we are inclined to deal with Marx. But even Marx apparently did not notice this ethical side of labour, because his focus was mainly on the creation of value, which was common among thinkers at that time, such as Locke and Smith. In contrast, Hegel consistently tackled the same issue from another angle: ethics. In terms of this, he went so far as to say the dignity of humans should be located in labour. We shed light on this very aspect of Hegel’s philosophy by reference to Alexandre Kojève’s famous commentary, Introduction à la lecture de Hegel.

Not a few feminist writers, such as Kristeva, Irigaray, and Chodorow, have dealt with Freud’s psychoanalysis so far, but it is not clear to what degree the Freudian theory grounds their arguments, because Freud himself developed his psychoanalysis mainly for the male mental world (Seelenleben). In this paper, we shall follow Freud’s train of thought exclusively from this angle. After the geneses of Pcpt.-Cs., id, ego, and super-ego (W-Bw, Es, Ich, and Über-Ich, respectively) are treated (§§7-10), we shed light on how these factors relate to the female spirituality (§§11-24) and why feminists could still rely on Freud’s thought (§25). On the other hand, the present research will also provide an easy introduction to Freud’s psychoanalysis, by reference to which each thinker could overview the Freudian theory (Fig. (5) and Fig. (8) will help). In this respect, we shall also take account of the masculine side of his discussion, that is to say, how a man usually develops his male personality, while we constantly put it in stark contrast to the female spirituality. Although, in this modern world, not a few thinkers criticize the Freudian theory as non-scientific like Popper did (§2), we should remember that there remain supporters of his theory, such as Grümbaum (§3). We shall touch on this kind of argument relating to philosophy of science in the first half of this paper, which will also provide some useful knowledge for the readers who still get doubtful of the Freudian theory and its usage in feminist arguments.

Addressing the question in the form of Kant’s maxim, this paper moves on to a more controversial topic in biomedical ethics, physician-assisted suicide. However, my conclusion is tentative, and what is worse, negative: I partially approve suicide. It does not imply a moral hazard. The situation is opposite: in the present times, terminal patients seriously wish it. I, as an author, put an emphasis on this very respect. Now suicide is, for certain circles, nothing but justice. The arguments of thinkers who approve suicide are also cited from this angle.

Although we often see references to Carnap’s inductive logic even in modern literatures, seemingly its confusing style has long obstructed its correct understanding. So instead of Carnap, in this paper, I devote myself to its necessary and sufficient commentary. In the beginning part (Sections 2-5), I explain why Carnap began the study of inductive logic and how he related it with our thought on probability (Sections 2-4). Therein, I trace Carnap’s thought back to Wittgenstein’s Tractatus as well (Section 5). In the succeeding sections, I attempt the simplest exhibition of Carnap’s earlier system, where his original thought was thoroughly provided. For this purpose, minor concepts to which researchers have not paid attention are highlighted, for example, m-function (Section 8), in-correlation (Section 10), C-correlate (Section 10), statistical distribution (Section 12), and fitting sequence (Section 17). The climax of this paper is the proof of theorem (56). Through this theorem, we will be able to overview Carnap’s whole system.

This paper is devoted to defending philosophical studies of mind, especially traditional ones. In my view, human mentality is a dialogue with myself, which has a social aspect that is never explained nor predicted by scientific studies. We firstly derive this picture from Descartes’ classical argmuments (§§2-3), and then develop it in the context of Kantian ethics (§4). Some readers think this combination arbitrary. However, these two philosophers agree on mind/body dualism (§5), and further, the fact that the dialogue is often made in an ethical situation leads us to Kantian ethics. We shall draw this developed picture within the format of modern practical syllogisms (§§5-13). Finally, we shall refer to Nick Zangwill’s normative essentialism for the completion of our whole picture (§§7-8).

Hans Jonas and Arne Næss have argued that philosophers need not be concerned with natural sciences even when they talk about enviromental issues like global warming (§1). However, believing sciences blindly is in itself unphilosophical. So we think, in this paper, the other way around: We consider the current view of global warming, which was reported by the IPCC, critically. The so-called AR4 is divided into two parts. One is about the industrial revolutions (§§5-9); the other is about the greenhouse effect (§§11-20). Through this consideration, it will be revealed: the views of the Establishment are not at all absolute; there still remains room to reconsider them.

The aim of this paper is to apply inductive logic to the field that, presumably, Carnap never expected: legal causation. Legal causation is expressible in the form of singular causal statements; but it is distinguished from the customary concept of scientific causation, because it is subjective. We try to express this subjectivity within the system of inductive logic. Further, by semantic complement, we compensate a defect found in our application, to be concrete, the impossibility of two-place predicates (for causal relationship) in inductive logic.

The aim of this paper is to call the attention, especially that of feminists, to the current progress in biology. It appears gender studies still confine themselves to outdated ideas of sex chromosomes like XX, XY (§10). However, science has been making progress. It no longer sticks to such matters as XX, XY. Its interest is now in Sry, a kind of gene (§11), and MIS, a kind of sex hormone (§14). Abnormalities of sex chromosomes are no longer evidence to deny the biological approaches, for example. We shed light on this fact, putting gender studies in the context of chronologies of science as well (§§2-9).

This paper takes two tasks. The one is elaborating on the relationship of inductive logic with decision theory to which later Carnap planned to apply his system (§§1-7); this is a surveying side of this article. The other is revealing the property of our prediction of the future, subjectivity (§§8-11); this is its philosophical aspect. They are both discussed under the name of belief in causation. Belief in causation is a kind of “degree of belief” born about the causal effect of the action. As such, it admits of the analysis by inductive logic.

Although written in Japanese, this book becomes a landmark of my works so far: that on Zangwill (Kaneko, 2011), that on Utilitarianism (2013), and so on. The novelty shown in it is a formalization of traditional philosophy including Kant (its practical philosophy), Utilitarianism (Hume, Bentham, and Mill), and furthermore, Descartes. I try to locate these traditional thoughts within modern forms which I make in the name of "practical syllogism." This attempt would open up a new approach to ethical motivation.
