Many researchers have assumed that punishment evolved as a behavior-modification strategy, i.e. that it evolved because of the benefits resulting from the punishees modifying their behavior. In this article, however, we describe two alternative mechanisms for the evolution of punishment: punishment as a loss-cutting strategy (punishers avoid further exploitation by punishees) and punishment as a cost-imposing strategy (punishers impair the violator’s capacity to harm the punisher or its genetic relatives). Through reviewing many examples of punishment in a wide range of (...) taxa, we show that punishment is common among plant and animal species and that the two mechanisms we describe have often been important for the evolution of punishment.

This paper examines ethics in finance, specifically related to responsible investment. In recent years, socially responsible principles are becoming the de facto standard not only for socially responsible but also for profitable investing. For instance, the United Nations developed the Principles for Responsible Investment (PRI) in 2006, which require institutional investors to incorporate ESG (Environmental, Social and Governance) issues into investment analysis and decision-making processes. This raises the following question: can responsible investments be justified from an ethical point of view? (...) In this paper I first explain responsible investments. Then, I turn to the ethical foundation of responsible investments. There are two arguments for responsible investments. I argue that both fail. Therefore, my conclusion is that the ethical foundation of responsible investments is not firm. (shrink)

In ${\mathbf{H}}$ , a set theory with the comprehension principle within Łukasiewicz infinite-valued predicate logic, we prove that a statement which can be interpreted as “there is an infinite descending sequence of initial segments of ω” is truth value 1 in any model of ${\mathbf{H}}$ , and we prove an analogy of Hájek’s theorem with a very simple procedure.

In my paper, I partially defend Philippa Foot’s view in answering the question ‘why be moral?’ In her book, Natural Goodness(2001) and her final paper, “Rationality and Goodness” (2004), Foot proposes two ideas: Ethical Naturalism and, what I call, the ‘Anti-Humean Theory of Practical Rationality’. In answering the question ‘why be moral?’, I argue that we should abandon the former and adopt the latter. In Section I, I discuss Foot’s Anti-Humean Theory of Practical Rationality. In Section II, I examine Foot’s (...) Ethical Naturalism. I argue that it is no longer defensible. In Section III, I examine other possible ways to integrate the categories of practical rationality. One is to take a utilitarian approach and another is to take a Kantian approach. I argue that the latter approach is in harmony with Foot’s Anti-Humean Theory of Practical Rationality. (shrink)

The evolution of altruism in human societies has been intensively investigated in social and natural sciences. A widely acknowledged recent idea is the “parochial altruism model,” which suggests that inter- group hostility and intragroup altruism can coevolve through lethal intergroup conflicts. The current article critically examines this idea by reviewing research relevant to intergroup conflicts in human evolutionary history from evolutionary biology, psychology, cultural anthropology, and archaeology. After a brief intro- duction, section 2 illustrates the mathematical model of parochial altruism (...) and some critiques of the model and its interpretation, primarily from an evolutionary biology point of view. Section 3 delves into the archaeological evidence of prehistoric intergroup conflicts in the Japanese archipelago’s Jomon and Yayoi periods, Europe’s Mesolithic period, and North America’s Pacific period as counter examples of the paro- chial altruism model. In section 4, the ethnographies of intergroup relationships and conflicts reveal that intergroup relationships in many ethnic groups are not as simple as the assumption in the mathematical model of parochial altruism. In section 5, we outline psychological research on intergroup conflicts which suggest that intergroup hostility and ingroup altruism are not necessarily correlated. In conclusion, we argue that the assumption and parameter settings of the parochial altruism model are inconsistent with empirical data. (shrink)

This study examines the relationship between Japanese archaeology and natural science through a quantitative analysis of the two most authoritative archaeological journals and two other relevant journals in Japan. First, although previous studies have emphasized the impact of the Department of Anthropology at the University of Tokyo on the scientific aspects of Japanese archaeology, results of the present study suggest that its impact has been more limited than previously assumed. Second, while previous studies claimed that research funding by the Japanese (...) government from the latter half of the 1970s was an important factor in developing the scientific aspects of Japanese archaeology, the present study shows a result inconsistent with the claim. Finally, although I admit that the previous studies have properly captured some aspects of the relationship between Japanese archaeology and science, I conclude that we should look at the broader array of contributors to the relationship between Japanese archaeology and natural science.

The paper is a critical comment on Okumura & Kanakogi (2019).

Whether man is predisposed to lethal violence, ranging from homicide to warfare, and how that may have impacted human evolution, are among the most controversial topics of debate on human evolution. Although recent studies on the evolution of warfare have been based on various archaeological and ethnographic data, they have reported mixed results: it is unclear whether or not warfare among prehistoric hunter – gatherers was common enough to be a component of human nature and a selective pressure for the (...) evolution of human behaviour. This paper reports the mortality attributable to violence, and the spatio-temporal pattern of violence thus shown among ancient hunter–gatherers using skeletal evidence in prehistoric Japan (the Jomon period: 13000 cal BC–800 cal BC). Our results suggest that the mortality due to violence was low and spatio-temporally highly restricted in the Jomon period, which implies that violence including warfare in prehistoric Japan was not common.

According to the theory of natural pedagogy, humans have a set of cognitive adaptations specialized for transmitting and receiving knowledge through teaching; young children can acquire generalizable knowledge from ostensive signals even in a single interaction, and adults also actively teach young children. In this article, we critically examine the theory and argue that ostensive signals do not always allow children to learn generalizable knowledge more efficiently, and that the empirical evidence provided in favor of the theory of natural pedagogy (...) does not defend the theory as presented, nor does it support a weakened version of the theory. We argue that these problems arise because the theory of natural pedagogy is grounded in a misguided assumption, namely that learning about the world and learning about people are two distinct and independent processes. If, on the other hand, we see the processes as interrelated, then we have a better explanation for the empirical evidence. (shrink)

The present study collected a larger set of three-dimensional data on human crania from the Kofun period (as well as from previous periods, i.e., the Jomon and Yayoi periods) in the Japanese archipelago (AD 250 to around 700) than previous studies. Three-dimensional geometric morphometrics were employed to investigate human migration patterns in finer-grained phases. These results are consistent with those of previous studies, although some new patterns were discovered. These patterns were interpreted in terms of demic diffusion, archaeological findings, and (...) historical evidence. In particular, the present results suggest the presence of a gradual geological cline throughout the Kofun period, although the middle period did not display such a cline. This discrepancy might reflect social changes in the middle Kofun period, such as the construction of keyhole-shaped mounds in the peripheral regions. The present study implies that a broader investigation with a larger sample of human crania is essential to elucidating macro-level cultural evolutionary processes. (shrink)

This paper reviews current situations of cultural evolutionary studies.

The present study examines the 3-dimensional data of human crania from the Yayoi period (800 BC to AD 250) of the Japanese archipelago by geometric morphometrics to investigate demic diffusion patterns. This is the first study on the Yayoi crania using their 3D data and geometric morphometrics with a much larger number of skeletal remains outside of the Kyushu regions than previous studies. The comparative results between the Jōmon and Yayoi samples show that the Yayoi people not only in the (...) eastern parts but also in the western parts of the archipelago are significantly different from the final Jōmon people and the Yayoi people were not strongly affected by the Jōmon people. A relatively gradual geological cline is also found among the Yayoi population, suggesting that the immigrants from the continental East Asia moved from the western parts to the eastern parts of the archipelago though the causes of the morphological changes are unclear.

The present research used archaeological data, i.e., the data obtained from kamekan jar burials in the Mikuni Hills of the northern Kyushu area in the Mid- dle Yayoi period, to test the parochial altruism model. This model argued that out-group hate and in-group favor coevolved via prehistoric intergroup conflicts. If this model is accurate, such an out-group hate and in-group favor could be re- flected in the archaeological remains, such as pottery making; the more frequent intergroup conflicts are and the (...) more each group is opposed, the more independent and coherent each group will be and more evident cultural identity could be estab- lished within each group. We employed an elliptic Fourier analysis for the shapes of kamekan jar burials. We examined whether frequent intergroup conflicts in the period influenced kamekan jar pottery between subareas of the Mikuni Hills. The results suggested that the shapes of kamekan jar burials after the KIIIa type are slightly different between subareas, which is partially consistent with the model. However, the results do not support the model directly. (shrink)

Gareth Evans proved that if two objects are indeterminately equal then they are different in reality. He insisted that this contradicts the assumption that there can be vague objects. However we show the consistency between Evans's proof and the existence of vague objects within classical logic. We formalize Evans's proof in a set theory without the axiom of extensionality, and we define a set to be vague if it violates extensionality with respect to some other set. There exist models of (...) set theory where the axiom of extensionality does not hold, so this shows that there can be vague objects. (shrink)

Various disciplines, including evolutionary biology, anthropology, archaeology, and psychology, have studied the evolution of rituals. Archaeologists have typically argued that burial practices are one of the most prominent manifestations of ritual practices in the past and have explored various aspects of burial practices, including burial directions. One of the important hypotheses on the cultural evolution of burial practices in Japan is the kitamakura hypothesis, which claims that burial directions (including Kofuns and current burials) were intended to be oriented toward the (...) north after the Kofun period under the influence of Confucianism or Buddhism. This hypothesis would be more plausible if burial directions were not oriented northward before the Kofun period. This research focused on the burial directions in the northern Kyūshū area of the Yayoi period, i.e., the directions of the kamekan jar burials. The results are almost consistent with the hypothesis, although one notable exception is found, and its possible interpretations and implications are discussed. (shrink)

BackgroundEach individual’s unique health-related beliefs can greatly impact the patient-clinician relationship. When there is a conflict between the patient’s preferences and recommended medical care, it can create a serious ethical dilemma, especially in an emergency setting, and dramatically alter this important relationship.Case presentationA 56-year-old man, who remained comatose after out-of-hospital cardiac arrest, was rushed to our hospital. The patient was scheduled for emergency coronary angiography when his adolescent daughter reported that she and her father held sincere beliefs against radiation exposure. (...) We were concerned that she did not fully understand the potential consequences if her father did not receive the recommended treatment. A physician provided her with in depth information regarding the risks and benefits of the treatment. While we did not want to disregard her statement, we opted to save the patient’s life due to concerns about the validity of her report.ConclusionsVariations in beliefs regarding medical care force clinicians to incorporate patient beliefs into medical practice. However, an emergency may require a completely different approach. When faced with a patient in a life-threatening condition and unconscious, we should take action to prioritize saving their life, unless we are highly certain about the validity of their advance directives.

We prove a set-theoretic version of Hájek, Paris and Shepherdson's theorem [HPS00] as follows: The set ω of natural numbers must contain a non-standard natural number in any natural Tarskian semantics of CŁ0, the set theory with comprehension principle within Lukasiewicz's infinite-valued predicate logic. The key idea of the proof is a generalization of the derivation of Moh Shaw-Kwei's paradox, which is a Russell-like paradox for many-valued logic.
