Some authors argue that we have a moral obligation to leave Mars the way it is, even if it does not harbour any life. This claim is usually based on an assumption that Mars has intrinsic value. The problem with this concept is that different authors use it differently. In this chapter, I investigate different ways in which an uninhabited Mars is said to have intrinsic value. First, I investigate whether the planet can have moral standing. I find that this (...) is not a plausible assumption. I then investigate different combinations of objective value and end value. I find that there is no way we can know whether an uninhabited Mars has objective end value and even if it does, this does not seem to imply any moral obligations on us. I then investigate whether an uninhabited Mars can have subjective end value. I conclude that this is very plausible. I also investigate whether an uninhabited Mars can have objective instrumental value in relation to some other, non-Mars related end value. I find also this very plausible. It is also highly plausible, however, that spreading (human or other) life to a presently uninhabited Mars can also have subjective end value, as well as objective instrumental value. I mention shortly two ways of prioritising between these values: (1) The utilitarian method of counting the number of sentient beings who entertain each value and determining the strength of the values to them. (2) Finding a compromise that allows colonisation on parts of the planet while leaving other parts untouched. These methods should be seen as examples, not as an exhaustive list. Also, I do not take a definitive stand in favour of any of the two approaches, though it seems at least prima facie that the second approach may have a better chance of actually leading to a constructive result.

The Precautionary Principle is both celebrated and criticized. It has become an important principle for decision making, but it is also subject to criticism. One problem that is often pointed out with the principle is that is not clear what it actually says and how to use it. I have taken on this problem by performing an analysis of some of the most influential formulations of the principle in an attempt to identify the core ideas behind it, with the purpose (...) of producing a formulation of the principle that is clear and practically applicable. It was found that what is called the Precautionary Principle is not a principle that tells us what do to achieve extra precaution or how to handle situations when extra precaution is called for. Instead, it was found to be a list of circumstances that each justify extra precaution. An analysis of some of the most common and influential formulations of the Precautionary Principle identified four such circumstances: (1) When we deal with important values that tend to be systematically downplayed by traditional decision methods – such as human health and the environment. (2) When we suspect that the decision might lead to irreversible and severe consequences and the values at stake are also irreplaceable, (3) When timing is at least as important as being right. (4) When it is more important to avoid false negatives than false positives. This interpretation of the Precautionary Principle does not say anything about what kind of actions to take when extra precaution is called for, but it does provide a clear and practically useful list of circumstances that call for extra precaution and that is not subject to the most common objections to the Precautionary Principle.

Uncertainty, insufficient information or information of poor quality, limited cognitive capacity and time, along with value conflicts and ethical considerations, are all aspects thatmake risk managementand riskcommunication difficult. This paper provides a review of different risk concepts and describes how these influence risk management, communication and planning in relation to forest ecosystem services. Based on the review and results of empirical studies, we suggest that personal assessment of risk is decisive in the management of forest ecosystem services. The results are (...) used together with a reviewof different principles of the distribution of risk to propose an approach to risk communication that is effective aswell as ethically sound. Knowledge of heuristics and mutual information on both beliefs and desires are important in the proposed risk communication approach. Such knowledge provides an opportunity for relevant information exchange, so that gaps in personal knowledge maps can be filled in and effective risk communication can be promoted. (shrink)

If we find life on another world, it will be an extremely important discovery and we will have to take great care not to do anything that might endanger that life. If the life we find is sentient we will have moral obligations to that life. Whether it is sentient or not, we have a duty to ourselves to preserve it as a study object, and also because it would be commonly seen as valuable in its own right. In addition (...) to this we would also have a duty to our fellow humans and other earthly life forms not to expose them to danger by advertently or inadvertently exposing them to potentially harmful space organisms. When space exploration turns into exploitation it will therefore be important to be able to show that a world that is up for exploitation is uninhabited before the exploitation starts. Showing that a world is uninhabited is, however, a different kind of task than showing that it is inhabited. The latter task can be accomplished through one positive finding but it is not clear how to go about the former task. In this paper I suggest that it is a gradual process asymptotically approaching certainty rather than a discovery in the traditional sense of the word. It has to be handled in two steps. The first is to connect degree of certainty with research setup. The second is to decide how certain we need to be. The first step is about the number, diversity and quality of observations. The second step is a decision we have to make based on the purpose of the investigation. The purpose and therefore the degree of certainty needed to establish that a world is uninhabited will be different for a world that is up for exploitation than for a world that is not. In the latter case it is only a matter of epistemic values. In the former case also ethical values have to be considered. (shrink)

The aim of this investigation is to answer the question of why it is prima facie morally wrong to cause or contribute to the extinction of species. The first potential answer investigated in the book is that other species are instrumentally valuable for human beings. The results of this part of the investigation are that many species are instrumentally valuable for human beings but that not all species are equally valuable in all cases. The instrumental values of different species also (...) have to compete with other human values. Sometimes these other values probably outweigh the value of the continued existence of the species. In general the degree of uncertainty is very high and the precautionaty principle is recommended to deal with these uncertainties. We also found that we have a duty to consider the interests of future generations of human beings and that these duties, in general, speak in favour of preservation. Anthropocentric instrumentalism therefore provides us with rather strong reasons to consider many cases of human caused extinction as prima facie morally wrong. Even so, anthropocentric instrumentalism does not fully account for the moral intuition we set out to investigate. The next potential answer that is investigated in the book is that species have a moral standing in their own right. The result of this part of the investigation is that this idea is highly unlikely, in particular because species cannot have any interests to consider. Anotgher potential answer is that species have intrinsic value in some other meaning that does not imply moral standing. We concluded that it is possible to be subjectively valued as an end and that many species have properties that make them highly suitable for being valued as ends by human beings. Finally, we found that our contributions to the extinction of species in most cases frustrate the interests of many non-human sentient beings. This is true if the species in question is made up of sentient individuals, and it is also true when the species in question is made up of non-sentient individuals that have instrumental value for sentient individuals of other species. There are exceptions to this rule, but all in all it seems that the inclusion of non-human sentient individuals together with us humans as moral objects, in most cases, tip the scale drastically in favour of preservation. The main result of the investigation is that there is not one but several explanations to why it is prima facie morally wrong to contribute to the extinction of species – and all of them are about duties to respect the interests of individual sentient animals, including human beings.

Values related to culture, identity, community cohesion and sense of place have sometimes been downplayed in the climate change discourse. However, they have been suggested to be not only important to citizens but the values most vulnerable to climate change. Here we test four empirical consequences of the suggestion: at least 50% of the locations citizens' consider to be the most important locations in their municipality are chosen because they represent these values, locations representing these values have a high probability (...) of being damaged by climate change induced sea level rise, citizens for which these values are particularly strongly held less strongly believe in the local effects of climate change, and citizens for which these values are particularly strongly held less strongly believe that they have experienced the effects of climate change. The tests were made using survey data collected in 2014 from 326 citizens owning property in Höganäs municipality, Sweden, and included values elicited using a new methodology separating instrumental values from end values, and using the former as stepping stones to pinpoint the latter, that represent the true interests of the respondents. The results provide the first evidence that, albeit frequent, values related to culture, identity, community cohesion and sense of place are not the values most vulnerable to climate change. This in turn indicates a need to further investigate the vulnerability of these values to climate change, using a methodology that clearly distinguishes between instrumental and end values. (shrink)

A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance. If extraterrestrial life has a moral standing in its own right, it will also affect what we have to do to protect it. The questions of how far we need to go to protect extraterrestrial life will be even more acute and complicated when the time comes to use habitable worlds for commercial purposes. (...) There will also be conflicts between those who want to set a world aside for more research and those who want to give the green light for development. I believe it is important to be proactive in relation to these issues. The aim of my project is therefore to identify, elucidate, and if possible, suggest solutions to potential conflicts between astrobiology, planetary protection, and commercial use of space. (shrink)

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Distribution of responsibility is one of the main focus areas in discussions about climate change ethics. Most of these discussions deal with the distribution of responsibility for climate change mitigation at the international level. The aim of this paper is to investigate if and how these principles can be used to inform the search for a fair distribution of responsibility for climate change adaptation on the local level. We found that the most influential distribution principles on the international level were (...) in turn built on one or more of seven basic principles: (P1) equal shares, (P2) desert, (P3) beneficiary pays, (P4) ability, (P5) self-help, (P6) limited responsibility for the worst off, and (P7) status quo preservation. It was found that all the basic principles, but P1, P3, and P7, are to some extent translatable to local climate adaptation. Two major problems hamper their usefulness on the local level: (1) several categories of agents need to take on responsibility; and (2) emissions do not work as a base for all principles. P4, P5, and P6 are applicable to local adaptation without changes. P4 is of particular importance as it seems to solve the first problem. P2 is applicable only if the second problem is solved, which can be achieved by using risk of harm instead of emissions as the basis for desert. (shrink)

If humans eventually attain the ability to create new life forms, how will it affect the value of life? This is one of several questions that can be sources of concern when discussing synthetic life, but is the concern justified? In an attempt to answer this question, I have analyzed some possible reasons why an ability to create synthetic life would threaten the value of life in general (that is, not just of the synthetic creations), to see if they really (...) give us reason to worry. The main conclusion is that it is unlikely that a future human ability to create life will really have a great negative impact on these characteristics of life. It therefore seems unlikely that the value of life will be negatively affected by the ability to create synthetic life, though it is possible that the properties in question will be less salient in the synthetic life and thus that the value of the synthetic life will be lower than that of existing life, which in turn can lead to a disturbing difference in value between different kinds of life.

Do forest owners’ levels of education or value profiles explain their responses to climate change? The cultural cognition thesis has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is greatest, (...) and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile. (shrink)

Om människan någon gång kommer att få förmågan att skapa nya livsformer, hur kommer det att påverka livets värde? Detta är en fråga som kan vara en källa till oro när man diskuterar konstgjort liv, men är oron befogad? I ett försök att svara på den frågan kommer jag att gå igenom några möjliga skäl till varför förmågan att skapa konstgjort liv skulle hota livets värde, och se om de verkligen ger oss skäl att oroa oss.

The aim of this chapter is to use philosophy and, in particular ethical theory, to identify and explore some potential conflicts.

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)

To gain legitimacy for climate change adaptation decisions, the distribution of responsibility for these decisions and their implementation needs to be grounded in theories of just distribution and what those a ected by decisions see as just. The purpose of this project is to contribute to sustainable spatial planning and the ability of local and regional public authorities to make well-informed and sustainable adaptation decisions, based on knowledge about both climate change impacts and the perceptions of residents and civil servants (...) on what constitutes a sustainable distribution of responsibility. Our aims are: (1) a better understanding of the practical implications of theories about just distribution of responsibility for the choice of local and regional climate adaptation measures; (2) knowledge about what residents and civil servants consider a sustainable distribution of responsibility for climate adaptation measures; and (3) a better understanding of conflicts concerning the distribution of responsibilities and systematic knowledge about the possibilities to manage them. In this interdisciplinary project, we study six municipalities and their residents, and two county administrative boards, all in Sweden, using mixed methods: value theory, document studies, interviews, focus groups, and surveys.

The project “A Plurality of Lives” was funded and hosted by the Pufendorf Institute for Advanced Studies at Lund University, Sweden. The aim of the project was to better understand how a second origin of life, either in the form of a discovery of extraterrestrial life, life developed in a laboratory, or machines equipped with abilities previously only ascribed to living beings, will change how we understand and relate to life. Because of the inherently interdisciplinary nature of the project aim, (...) the project took an interdisciplinary approach with a research group made up of 12 senior researchers representing 12 different disciplines. The project resulted in a joint volume, an international symposium, several new projects, and a network of researchers in the field, all continuing to communicate about and advance the aim of the project.

I årtusenden har människan försökt definiera livet – hur levande djur och växter skiljer sig från död materia. Problemet är dock att livet är mångfacetterat, och varje regel har sitt undantag. Vi försöker möta kommande utmaningar med nya livsformer, genom att lyfta fram en ny definition av liv.

Wind damage to forests can be divided into (1) the direct damage done to the forest and(2) indirect effects. Indirect effects may be of different kinds and may affect the environ- ment as well as society. For example, falling trees can lead to power and telecommunica- tion failures or blocking of roads. The salvage harvest of fallen trees is another example and one that involves extremely dangerous work. In this overview we provide examples of different entities, services, and activities that (...) may be affected by wind damage to for- ests. We illustrate how valuation of the damage depends on the perspective applied and how the affected entities, services, and activities may represent different types of values. Finally we suggest means for how to actively manage the risk in an ethically sustainable way. Many of our examples will be drawn from the experiences of the wind damage Gudrun in southern Sweden on 8–9 January 2005. The direct as well as indirect effects, which are described, are by no means unique to the Gudrun wind damage event and similar or even worse effects have been described after the wind damage events Martin and Lothar in 1999, and Klaus in 2009.

When working with garden archaeology and garden archaeobotany, the plant material is of great importance. It is important to be able to identify which plants have grown in a particular garden and which have not, which of the plants you find in the garden today that are newly introduced or have established themselves on their own, and which plants that may be remnants of earlier cultivation. During the past two years, my colleagues and I have been involved in a project (...) that deals with the latter kind of plants, that is, plants that were once actively cultivated and that have survived in their original place of cultivation until the present time(Persson, Ansebo & Solberg, this volume). When we started the project we simply called the plants we worked with ‘relict plants’. This is also the term that has been used unofficially in this field of research for some time. It was in no way an official term, however, and as it turned out, the term already had a different meaning in botany that was both older and better established. We were therefore in need of a better name for the plants we worked with. To single out the plants we were working with, we used the following working definition: “Plants that were once, but are no longer cultivated in a certain area, and where a part of the population still exists even though it is no longer actively maintained”. Although we still think this is a decent approximation, we have realized that there are several complicating factors we have had to think more about. We thus needed both a better name and a better definition. Both these tasks became important parts of the project. (shrink)

Review of James S. J. Schwartz and Tony Milligan, eds.: The Ethics of Space Exploration.

Sokrates var inte bara en filosofisk nydanare. Genom sitt sätt att involvera sina samtalspartners i den filosofiska processen var han också i hög utsträckning en pedagogisk nydanare. Hans pedagogiska grundidé var den så kallade majeutiska metoden – det vill säga ”barnmorskemetoden”. Med det menade han att han inte överförde sina egna färdiga tankar till den han talade med utan han hjälpte sin samtalspartner att föda sina egna tankar. Inom pedagogiken är det vanligt att använda den så kallade ”Sokratiska metoden” vilket (...) i sin enklaste form bara innebär att man ställer frågor till studenterna. Den här artikeln kommer emellertid att handla om en mer sofistikerad metod som används för begreppsanalys/begreppsdefinition i grupp. Metoden är inspirerad av Sokrates men skiljer sig också en del från hur Sokrates själv grep sig an sina dialoger – åtminstone så som de beskrivs av Platon. Artikeln innehåller en kort historisk och pedagogisk bakgrund men syftar framför allt till att utgöra en praktisk vägledning för genomförande av sokratiska dialoger i filosofiundervisningen. Artikeln bygger framför allt på mina egna erfarenheter av att använda Sokratisk Dialog i undervisningen vid Filosofiska institutionen vid Lunds universitet, Lunds Tekniska Högskola, Sveriges Lantbruksuniversitet och i det privata näringslivet. Artikeln vänder sig till alla som undervisar i filosofi på universitetet eller gymnasiet eller i filosofiska metoder för studenter vid andra utbildningar, t.ex. värdeteori, vetenskapsteori eller tillämpad etik för ingenjörer eller medicinare – eller i vilket annat ämne som helst där det förekommer begrepp som saknar en enkel och knivskarp definition men som är viktiga för ämnet.

The term ’risk’ is used in a wide range of situations, but there is no real consensus of what it means. ‘Risk ‘is often stipulatively defined as “a probability for the occurrence of a negative event” or something similar. This formulation is however not very informative, and it fails to capture many of our intuitions about the concept or risk. One way of trying to find a common definition of a term within a group is to use a Socratic Dialogue (...) (SD). This method is fairly new, and it is rather different from the original Socratic dialogues (at least if we are to judge from how they are described by Plato). The best explanation for the name ought to be that it is inspired by the original Socratic dialogues. The SD in its modern form was originally developed as a tool for enabling laymen to perform rather advanced concept analyses under the supervision of a professional philosopher. The formal goal of the method is to find a common way of perceiving of a particular term, or at least to find out exactly how the members of the group differ in their understandings of the term, and why. The largest gain from the process has in practice turned out to be a higher awareness among the participants of different ways of understanding the term, and the ideas and intuitions behind it. This has turned out to be very useful in educational settings, but the method has also been used with great success both in research, and in e.g. business, public administration and nongovernmental organisations. In the present case, a Socratic dialogue on the concept of risk was performed within the framework of a Ph D-course about risk and uncertainty at the Swedish University of Agriculture in Alnarp, Sweden. The participants on the course where all quite familiar with practical issues relating to risks. Both from the course work, and from their own research. (shrink)

The aim of the Nordic Network for the Archaeology and Archaeobotany of Gardening (NTAA), as it was phrased those first days in Alnarp in the beginning of March 2010, is to: ”bring researchers together from different disciplines to discuss the history, archaeology, archaeobotany and cultivation of gardens and plants”. We had no idea, then, how widely appreciated this initiative would become. The fifth seminar in five years was held on Visingsö June 1-3, 2014 and the sixth seminar will take place (...) in Kristiansand, Norway, June 12-14, 2015. We are very pleased to be able to publish this report, Sources to the History of Gardening: Four Interdisciplinary Seminars 2010–2013, Arranged By the Nordic Network for the Archaeology and Archaeobotany of Gardening (NTAA), based on the first four themes and seminars, in total 26 articles. Most of them origins from one of the seminar contributions 2010, 2011, 2012 and 2013 respectively. However, the editorial group has taken the opportunity, with the aim of the network in mind, to add supplementing contributions on some subjects. The articles are arranged in four themes according to the themes of the seminars. The first theme Archaeological Sources to the History of Gardens and the Cultural Landscape is linked to the first seminar in Alnarp, Sweden, 2010 which had a focus on method, the important connections between archaeology and archaeobotany and the interesting progress within garden archaeology during the last decade. The second theme Cabbage Patches and Kitchen Gardens deals with the second seminar in Norrköping, Sweden, 2011. Its focus was on historical, cultural geographical, archaeological and archaeobotanical research concerning utility gardens or kitchen gardens as well as the concept ‘kålgård’ (cabbage patch or kale yard), its shape and content over time. The third theme Cultural and Garden plants: Under Ground, Above Ground, In Herbariums and Archives connects to the third seminar in Uppsala, Sweden, 2012. It focused on sources, source criticism and interdisciplinary research to gain knowledge on the history of garden cultivation and cultural plants. The articles discuss, among other things, herbariums, written sources, DNA and molecular markers, pollen analysis and georadar. The fourth theme for NTAA’s annual seminar was Cultural Relict Plants and was held on Bornholm, Denmark, 2013. The focus on the seminar was on research and conservation of cultural relict plants, that is cultural plants which have survived in the same place for a long time after the actual cultivation has ceased. We dedicate this report to Kjell Lundquist (1955-2011) who were one of the initiators to this network and we hope it will inspire continuous research and new methodological discussions. (shrink)

This book describes the state of astrobiology in Europe today and its relation to the European society at large. With contributions from authors in more than 20 countries and over 30 scientific institutions worldwide, the document illustrates the societal implications of astrobiology and the positive contribution that astrobiology can make to European society. The book has two main objectives: 1. It recommends the establishment of a European Astrobiology Institute (EAI) as an answer to a series of challenges relating to astrobiology (...) but also European research, education, and society at large. 2. It also acknowledges the societal implications of astrobiology, and thus the role of the social sciences and humanities in optimizing the positive contribution that astrobiology can make to the lives of the people of Europe and the challenges they face.

The book contains the first part of an investigation aimed at finding out why it is morally wrong to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer to the instrumental value of the species for human beings – the (...) anthropocentric instrumental approach as I have chosen to call it. This is the answer that is discussed in this book. We have found many ways in which different species have instrumental value for human beings – both individually and as a part of ecosystems and of biodiversity in general. We could not guarantee however that this includes all species. In some cases, it also turned out that the instrumental value of the species in fact favours exploitation maybe even as far to the extinction of the species. We also noticed that there is no guarantee that the instrumental value of the species can always outweigh the competing values that we would gain by different encroachments that contribute to the extinction of the species. We found however that there are some special circumstances that help push the scale in the direction of preservation. I am thinking of some particular types of value such as choice value and transformation value – values that in general seem to favour preservation of species. This principle shows us that it would be rational from an anthropocentric instrumental vantage point to rule in favour of preservation in many of the cases where we are uncertain about the value of the species, about the best way of utilising the value, or about the connection between the species and other species or biodiversity in general. I am finally thinking of the moral principle that we have duties to consider the future interests of generations to come. We found that with a few exceptions it is justified to adopt such a principle. This in combination with the principles of precaution ought in general to urge us not to cause the extinction of species unless we have very trustworthy evidence that they will not turn out to be more valuable alive to future generations in comparison to what we can get from driving them to extinction. In relation to the discussion about the value of other species for human beings, it is worth noticing that all the arguments we have found in favour of preservation would be even stronger – and therefore account even better for the intuition that it is at least prima facie wrong to cause extinction – if we also accepted that other entities than human beings can have moral standing. Finally, we noticed that our moral intuitions strongly indicate that even in the cases where the instrumental value of other species for human beings talks in favour of preservation, there is still something lacking. Something we have to account for in order to totally account for our moral intuition against extinction. The conclusion will have to be that anthropocentric instrumentalism is in favour of preservation in many cases – probably in more cases than is generally acknowledged – but that it is not enough to give a complete account of the intuition that it is prima facie morally wrong to contribute to the extinction of species. We therefore have to continue our search for such an account. (shrink)
