Our ultimate purpose is to give an axiomatic treatment of recursion theory sufficient to develop the priority method. The direct or abstract approach is to keep in mind as clearly as possible the methods actually used in recursion theory, and then to formulate them explicitly. The indirect or experimental approach is to look first for other mathematical theories which seem similar to recursion theory, to formulate the analogies precisely, and then to search for an axiomatic treatment which covers not only (...) recursion theory but also the analogous theories as particular cases.The first approach is more general because it does not depend on the existence of analogues. A concrete mathematical theory, it seems, need have no such analogues and still be important, as e.g. classical number theory. In such a case, an axiomatic treatment may still be useful for exhibiting the mathematical structure of the theory considered and the assumptions on which it rests. However, it will lack one of the most heavily advertised advantages of the axiomatic method, namely, the “economy of thought” which results from an uniform theory for several different and interesting cases: we cannot hope for this if, by hypothesis, we know of only one particular case. In contrast, the second approach, if successful at all, is bound to achieve such “economy” because we start out with several interesting particular cases. Another possible virtue of the second approach is that of field work over insight: the abstract pattern that we are looking for and hoping to formalize in axioms, may not be evident in any one mathematical theory, but may spring to the eye if one happens to look simultaneously at several theories which happen to realize the pattern.

According to the prevailing sentiment, changing the past is logically impossible. The prevailing sentiment is wrong. In this paper, I argue that the claim that changing the past entails a contradiction ultimately rests upon an empirical assumption, and so the conclusion that changing the past is logically impossible is to be resisted. I then present and discuss a model of time which drops the empirical assumption and coherently models changing the past. Finally, I defend the model, and changing the past, (...) against objections.

In this thesis I argue for the following theory: constitutive Russellian phenomenal bonding panpsychism. To do so I do three main things: 1) I argue for Russellian panpsychism. 2) I argue for phenomenal bonding panpsychism. 3) I defend the resultant phenomenal bonding panpsychist model. The importance of arguing for such a theory is that if it can be made to be viable, then it is proposed to be the most promising theory of the place of consciousness within nature. This is (...) because constitutive Russellian panpsychism has all the theoretical virtues of physicalism and dualism but does not face the problems they do. The combination problem, however, is the most significant problem for the Russellian panpsychist, and, hence, in order to show the viability of the theory I address this problem. Moreover, I present a novel ”mereological argument’ for panpsychism which makes it necessary that the Russellian panpsychist addresses the combination problem. The focus of this thesis is therefore addressing this problem. I argue that the combination problem can indeed be solved. To do so I argue for the phenomenal bonding solution proposed by Goff. I argue that this solution works and that we can form a positive concept of the phenomenal bonding relation. This forces the panpsychist to make sense of how experiencing subjects can be proper parts of other experiencing subjects. I then argue that this can indeed be made sense of and show that we can indeed be composite subjects made of other subjects. To show that we can be subjects made up of other subjects I defend this proposal from various objections from throughout the literature. All these objections can be responded to by the constitutive Russellian phenomenal bonding panpsychist. Ultimately this leaves us with a novel and interesting account of what conscious subjects are, and what the material world is: they are both composite entities made wholly of conscious matter.

An alleged moral right to informational privacy assumes that we should have control over information about ourselves. What is the philosophical justification for this control? I think that one prevalent answer to this question—an answer that has to do with the justification of negative rights generally—will not do.

This article discusses the concept of God with a focus on the translation of God in the Chinese and Yoruba religious contexts. Translating the word God is of the essence when comparing concepts of god. The translation of the Christian God as Olodumare misrepresents the latter. As suggested by Africanists, there should be appropriate translations for God, Olodumare, and other African gods. As a preliminary comparative attempt, this article presents a case on the introduction of God to the Chinese people. (...) The translation of God into Chinese reflects different views regarding the correlation between the Christian God and the Chinese gods. (shrink)

Like all research, embryo research can take a variety of forms, some posing substantially more risks to persons than others. Savulescu et al argue persuasively that regulatory regimes specially designed for sensitive embryo research should differentiate between person-affecting and non-person-affecting embryo research, with substantial scrutiny only warranted for the former.1 Yet if we find Savulescu et al ’s argument persuasive, what practical implications would it have? In this commentary, we focus in particular on how such an argument might apply in (...) Singapore, one of the jurisdictions with special regulations for embryo research. We will summarise the way in which approval for oocyte and embryonic research operates in Singapore, and suggest that Savulesc et al ’s distinction requires specification to be useful in such contexts. We propose adopting a risk-stratified framework similar to that employed with Institutional Review Boards. This requires a wider view of risks than the focus by Savulescu et al on future persons. We then illustrate how such a framework would apply in five scenarios discussed in Savulescu et al. Research with embryos and oocytes is regulated in Singapore under the Human Biomedical Research Act.2 Enacted in 2015, this law sets out requirements for consent, IRB review and research oversight. By definition, all research involving gametes and embryos fall within the remit of the Act. Moreover, such research is defined as ‘restricted’; besides the Act, research involving oocytes and embryos is also subject to control under the Human Biomedical Research …. (shrink)

This article presents evidence supporting the claim that ethical reasoning is a skill that can be taught and assessed. We propose a working definition of ethical reasoning as 1) the ability to identify, analyze, and weigh moral aspects of a particular situation, and 2) to make decisions that are informed and warranted by the moral investigation. The evidence consists of a description of an ethical reasoning education program—Ethical Reasoning in Action —designed to increase ethical reasoning skills in a variety of (...) situations and areas of life. ERiA is housed at a public, major comprehensive U.S. university—James Madison University—and assessment of the program focuses on interventions delivered prior to and during orientation for incoming first-year students. Findings indicate that the interventions measurably enhance the ability of undergraduate students to reason ethically. ERiA’s competency-targeted program and positive student learning outcomes offers a promising model for higher education ethics programs seeking to connect classroom learning in ethics to decision-making in everyday life.

Este ensayo presenta una visión de conjunto del modo en el cual el «giro» (Kehre) hacia el pensamiento ontohistórico, a medidados de los años ’30, impacta sobre la concepción aleteiológica que, siguiendo a E. Lask y E. Husserl, Heidegger elabora desde comienzos de los años ‘20 hasta Sein und Zeit. Sobre esa base, se ofrece también un intento de caracterización de la reformulación eventualista-kairológica de la aleteiología presentada en Beiträge zur Philosophie. La caracterización propuesta se lleva a cabo con arreglo (...) a la distinción entre un nivel metahistórico de consideración, que corresponde al intento de pensar el seren su verdad en términos de la noción de «acontecimiento» (Ereignis), y un nivel propiamente histórico de consideración, que corresponde a la «hermenéutica de los dos comienzos». El pensar que medita históricamente el ser en su verdad sólo puede ser fiel a la intrínseca movilidad del ser mismo, si se ejerce en y desde la quietud de la contención, como temple animímico fundamental.

The theme of the paper is defined by the relevance and insufficient scientific elaboration of the concept of dental tourism in Russia on the basis of deep, comprehensive and conceptually oriented research. The article presents the analytical review of foreign literature in the field of dental tourism. The authors consider various approaches to the definition of the conceptof dental tourism. Scientific developments which are devoted to the dental tourism have not been conducted in our country yet. Mainly, the scientific developments (...) in the sphere of dental tourism are conducted for advertising purposes. The authors points to the possibility and necessity of this study within the framework of sociology of medicine which has the methodological and operational basis for achieving the planned result.

Medical decisions regarding end-of-life care have undergone significant changes in recent decades, driven by changes in both medicine and society. Catholic tradition in medical ethics offers clear guidance in many issues, and a moral framework accessible to those who do not share the same faith as well as to members of its faith community. In some areas, a Catholic perspective can be seen clearly and confidently, such as in teachings on the permissibility of suicide and euthanasia. In others, such as (...) withdrawal of nutrition and hydration, the Church does not yet speak with one voice and has not closed out the discussion. Yet, it is not in the teaching on individual issues that a Catholic moral tradition offers the most help and comfort, but in its account of what it means to lead a life in Christ, and to prepare for a Christian death. As in the problem of pain and suffering, it is the spiritual support more than the ethical guidance that helps both patients and physicians bear the unbearable and fathom the unfathomable. (shrink)

The complex chaotic dynamics and multistability of financial system are some important problems in micro- and macroeconomic fields. In this paper, we study the influence of two-delay feedback on the nonlinear dynamics behavior of financial system, considering the linear stability of equilibrium point under the condition of single delay and two delays. The system undergoes Hopf bifurcation near the equilibrium point. The stability and bifurcation directions of Hopf bifurcation are studied by using the normal form method and central manifold theory. (...) The theoretical results are verified by numerical simulation. Furthermore, one feature of the proposed financial chaotic system is that its multistability depends extremely on the memristor initial condition and the system parameters. It is shown that the nonlinear dynamics of financial chaotic system can be significantly changed by changing the values of time delays. (shrink)
