The original interest of this article lies in existential import. It provides a broader view on the problem by reference to modern, symbolic logic (ch.1). Gradually, however, our interest will change into the amalgamated expressions often used in logic; that is, why are such expressions as “x is a round triangle” applied in logic? We critically discuss this question from an extensional viewpoint, namely model theoretic semantics (ch.2). We also touch on Church’s λ-calculus in the appendix (app.2).

This article handles a series of articles written by Suzuki (2016a; 2016b; 2018), in which he put forward the anti-psychologism, a new standpoint of action theory. This standpoint, however, has lost the path Anscombe originally opened up, seemingly. Anscombe’s point (called “Anscombe’s motif” in this article) was: the agent him/herself responds, by revealing his/her original motive, to the question “Why did/do you do…?” Leaving this ground, in modern theories, one sees an unfamiliar idea like a normative reason flow into the debate on human action. We review this academic environment critically in terms of Kaneko (2017), whom Suzuki criticized in one of his papers (2018).

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.
