This article examines some selected ethical issues in human space missions including human missions to Mars, particularly the idea of a space refuge, the scientific value of space exploration, and the possibility of human gene editing for deep-space travel. Each of these issues may be used either to support or to criticize human space missions. We conclude that while these issues are complex and context-dependent, there appear to be no overwhelming obstacles such as cost effectiveness, threats to human life or (...) protection of pristine space objects, to sending humans to space and to colonize space. The article argues for the rationality of the idea of a space refuge and the defensibility of the idea of human enhancement applied to future deep-space astronauts. (shrink)

As we look beyond our terrestrial boundary to a multi-planetary future for humankind, it becomes paramount to anticipate the challenges of various human factors on the most likely scenario for this future: permanent human settlement of Mars. Even if technical hurdles are circumvented to provide adequate resources for basic physiological and psychological needs, Homo sapiens will not survive on an alien planet if a dysfunctional psyche prohibits the utilization of these resources. No matter how far we soar into the stars, (...) our psychologies for future generations will be forever tethered to the totality of our surroundings. By shaping our environment toward survival and welfare during the voyage to Mars and in a Martian colony, we indirectly shape our psyches and prepare them for a mission of unprecedented alienation and duration. Once on Mars, human factors such as leadership structure, social organization and code of conduct, group size, gender balance, developmental cycle, mobility, length of stay and the ecological settings and type and manner of subsistence, will create a novel Martian culture. The degree that settlers are severed from the Earth will affect how radically foreign this culture will be when compared with cultures on Earth. (shrink)

While humans have made enormous progress in the exploration and exploitation of Earth, exploration of outer space remains beyond current human capabilities. The principal challenges lie in current space technology and engineering which includes the protection of astronauts from the hazards of working and living in the space environment. These challenges may lead to a paradoxical situation where progress in space technology and the ability to ensure acceptable risk/benefit for human space exploration becomes dissociated and the rate of scientific discovery (...) declines. In this paper, we discuss the predominant challenges of the space environment for human health and argue that development and deployment of a human enhancement policy, initially confined to astronauts – for the purpose of future human space programmes is a rational solution to these challenges.

This article presents an empirical examination of the consequences of the virtual entailment principle proposed by Jean Buridan to resolve the Liar paradox. This principle states that every sentence in natural language implicitly asserts its own truth. Adopting this principle means that the Liar sentence is not paradoxical but false, because its content is contradictory to what is virtually implied. As a result, humans should perceive the Liar sentence the same way as any other false sentence. This solution to the (...) Liar paradox received criticism for making ad hoc claims about the natural language. However, thanks to modern advancements in psychophysiology, it became possible to empirically investigate if the human brain really perceives the Liar sentence like a false sentence. We designed and conducted an experiment to examine brain activity in response to true sentences, false sentences and self-referential sentences. Our results provide support for the Buridan’s hypothesis and show that the Liar sentence is processed by the human brain identically to false sentences, while the Truthteller sentence is perceived identically to true sentences. This agrees with predictions derived from the virtual entailment principle and supports the idea that humans think with the logic of truth—a logic for which the truth is a designated value of its adequate semantics.

:Any space program involving long-term human missions will have to cope with serious risks to human health and life. Because currently available countermeasures are insufficient in the long term, there is a need for new, more radical solutions. One possibility is a program of human enhancement for future deep space mission astronauts. This paper discusses the challenges for long-term human missions of a space environment, opening the possibility of serious consideration of human enhancement and a fully automated space exploration, based (...) on highly advanced AI. The author argues that for such projects, there are strong reasons to consider human enhancement, including gene editing of germ line and somatic cells, as a moral duty. (shrink)

Scholars employing an evolutionary approach to the study of religion and religious beliefs search for ultimate explanations of the origin, propagation, and persistence of religious beliefs. This quest often pairs in debate two opposing perspectives: the adaptationist and “by-product” explanations of religion and religious beliefs. The majority of scholars prefer the by-product approach, which is agnostic and even doubtful of the usefulness of religious beliefs. Despite this pervasive negativity, it seems unwarranted to deny the great usefulness of religious beliefs—particularly concerning (...) their past utility. Instead, adaptationist explanations of religion and religious beliefs must be re-established as interesting and useful approaches to the study of religious beliefs. (shrink)

Biomedical moral enhancement is an idea which states that human moral intuitions and patterns may be artificially improved by biomedical means. The rationale which lies behind moral bioenhancement is rooted in the idea that humans – in a moral and behavioral sense – are not evolutionally adapted to current ecological challenges. This idea is discussed in the paper in relation to human space missions to Mars and beyond. Because the space environment is a hazardous environment, there are some reasons to (...) consider the idea of moral bioenhancement for the purposes of mission success and the safety of astronauts/space settlers. This paper discusses that idea in the context of a broader discussion on moral enhancement, moral bioenhancement related to earthly issues, and the idea of moral progress. (shrink)

W tekście rozważane są zagadnienie realności i związana z nim tematyka epistemologiczna w trzecim okresie filozofii Fryderyka Nietzschego. Analizując ten obszar filozofii Nietzschego, autor zwraca szczególną uwagę na problem życia. Opisuje go za pomocą metafory pnącej się wzwyż spirali. Metafora ta rozwijana jest przez autora w kontekście koncepcji „ekstatycznego tańca kratofanicznego” Zbigniewa Kaźmierczaka. Autor rozpoczyna rozważania od interpretacji stanowiska Nietzschego na temat trzech władz poznawczych: świadomości, rozumu i języka metafizycznego. Następnie stara się opisać wpływ, jaki — zdaniem filozofa — wywierają (...) one na powstanie koncepcji realności. Z tego powodu przechodzi do analizy struktury woli. W ostatniej części tekstu autor dokonuje analizy koncepcji realności, zestawiając wyniki badań z metaforą spirali. (shrink)

The question is whether the message of early Christianity was revolutionary and aimed at a revolutionary change in history? Had this change already begun in the life of primitive Christianity in a way that is exemplary to all later life based on the message?

There are mathematical structures with elements that cannot be distinguished by the properties they have within that structure. For instance within the field of complex numbers the two square roots of −1, i and −i, have the same algebraic properties in that field. So how do we distinguish between them? Imbedding the complex numbers in a bigger structure, the quaternions, allows us to algebraically tell them apart. But a similar problem appears for this larger structure. There seems to be always (...) a background and a context that we rely upon. Thus mathematicians naturally make use of Kantian intuition and references fixed by names and denotations. I argue that such features cannot be avoided. (shrink)

In this paper I consider how theology impacted on the uprising philosophy in ancient Greece. In the €rst part of my text I analyze the concept of theology and philosophy and I want to know the relation between these two ideas. I am especially interested in point of the line separating theology and philosophy. e main question concerning it is when we could say about theology that it is already philosophy, and reversely – when we could say about philosophy that (...) it is still theology in Greek meaning. For the better understanding of the answer of this question I analyze Hesiod’s Teogony. Hesiod of Beotia is accepted as a poet and theologian and that is why I pay attention to him in the second part of my text. (shrink)

"Ist der Patient ein Mensch?" is a collection of articles. Its central topic is the question if the object of modern medicine is still the human being or if just organs and tissues are treated by medical doctors? The drawing on the book cover shows a lung instead of a human patient lying in a hospital bed. The approaches to this topic are diverse and surprising. E.g. the surgeon Ankersmit argues that it is impossible for him to see the human (...) being in the body lying on the operation table because then he would be unable to perform his work professionally. Other texts stretch the topic of the book to the questions whether medical doctors are human beings or if the human being of today is a "patient" in the sense of a current crisis of anthropology. Also questions like patient autonomy and communication with patients are tackled. The book is edited by Helmut Hofbauer, Lukas Kaelin, Hendrik Jan Ankersmit & Walter Feigl. Authors are: Lukas Kaelin, Gabriele Baumann, Hendrik Jan Ankersmit, Renate Heinz, Claus G. Krenn, Alexander Lapin, Sigrid Pilz, Margot Ham-Rubisch, Petra Herzeg, Klaus Spiess, Lucie Strecker, Paul Ferstl, Helmut Hofbauer & Peter Kampits. (shrink)

Mathematicians often say that their theorems, proofs, and theories can be beautiful. They say mathematics can be like art. They know how to move creatively and freely in their domains. But ordinary people usually cannot do this and do not share this view. They often have unpleasant memories from school and do not have this experience of freedom and creativity in doing mathematics. I myself have been a mathematician, and I wish to highlight some of the creative aspects in doing (...) mathematics. I always had the feeling that there is much freedom in mathematics and that one can do as one pleases as long as one avoids contradictions (and one can even live with contradictions for a while). In mathematics one only needs to define something and there it is! Just imagine it, and it immediately exists. Where else, besides fiction, does one have such power? --- This essay has three parts. In the first, I lay out some historical facts and views that I will need later. Second, I insert an interlude with Kant, pointing out some of his claims and insights in aesthetics, and some aspects in mathematics that I think he overlooked or underestimated. Third, I will bring out some aspects of higher mathematics that I will show are similar to art. These aspects are in the doing and creating of mathematics, not in the finished theories. They are usually not found in textbooks. I want to show that a researcher in mathematics is like a painter or composer, exploring and creating. To see this, one has to adopt a first-person perspective. In this way I will show that aesthetics plays a role and leaves its traces also in mathematics. (shrink)
