This paper studies the philosopher Ludwig Wittgenstein during his years (1920–26) as an elementary school teacher in remote Niederösterreich, Austria. The paper gives a survey of his life, and also a brief account of three of his main works: Tractatus Logico-Philosophicus, Philosophical Investigations and Remarks on the Foundations of Mathematics. Attention is given to his alphabetical word list, Wörterbuch für Volksschulen, published for educational use in elementary schools. The study is focused on Wittgenstein’s educational practise, and establishes a connection between his experience as a teacher and his late philosophy.

Abortion is clearly one of the most controversal and divisive contemporary moral problems. This thesis is an investigation upon significant number of important, fundemental ethical questions in relation to policy of abortion in Nigeria.

In this thesis I present and discuss the phenomenon of ethical fading, and its association with biased assessment of a fair action. Ethical fading is an intuitive, self-deceptive, unconscious mechanism by which even morally competent agents are lead to disregard the ethical consequences of a particular choice. In engaging in this psychological mechanism, I argue, agents are also presupposing a biased assessment of entitlement. This biased assessment of fairness is intentionally dubious, and to be found in decision frames and reinforced by contexts. In the final part of the work I present an applied ethics case to show how ethical fading may be a quite prevalent pattern of behavior.

I Logische Untersuchungen formulerade Edmund Husserl sin fenomenologi – ”en filosofi som sträng vetenskap”. Fenomenologin med dess metod, epochén, skall utövas under parollen ”Till sakerna själva!” Genom att ifrågasätta invanda tankesätt skall vi sätta världen inom parentes och därigenom nå objektiv kunskap. Denna uppsats behandlar intersubjektivitetsproblemet hos fenomenologin. Genom en studie av Husserls Cartesianische Meditationen, Martin Heideggers Sein und Zeit och Maurice Merleau-Pontys Phénoménologie de la perception närmar jag mig frågan om ”De andra hos Merleau-Ponty”. Hur kan vi förstå den andre och annanheten när fenomenologins epoché är en metodisk solipsism som berövar subjektet dess värld? Merleau-Ponty gör oförnuftet, tvetydigheten och slumpen till tema för sitt tänkande. Genom perceptionen varseblir vi världen och subjektet är (i) sin värld genom den levda kroppen. Det finns inget ”inre” utan det är genom världen, och vår verksamhet däri, som vi känner oss själva. Merleau-Pontys subjekt är ”vikt åt världen”. / In Logische Untersuchungen Edmund Husserl defined his phenomenology as a science for finding objectivity. The method of phenomenology, the phenomenological reduction, would provide knowledge on indubitable grounds by going back “to the things themselves”. We must put the world aside if we want to find objective knowledge. This essay is a reading of Edmund Husserls Cartesianische Meditationen, Martin Heideggers Sein und Zeit and Maurice Merleau-Pontys Phénoménologie de la perception, and their theories of the others. How can we understand other in our mind when phenomenology in the course of its methodological solipsism, thought the phenomenological reduction, would seem to deprive the subject from the world? Merleau-Ponty makes ambiguity and accidental existence a theme for his philosophy. Through perception we apprehend the world, as lived through with our bodies. There is no “inner man”. With some else’s words: ”Your abode is your act itself. Your act is you.”

Inspired by Kitaro Nishida’s concept of pure experience this thesis analyses Bergson’s concept of experience with the intention of showing how experience is related to duration and how this in turn destabilizes certain tendencies towards subjectivism that can be found in Bergson’s work. This is accomplished through a reading of Matter and memory, Creative Evolution and Introduction to metaphysics that tries to desintegrate both subject and object in favor of duration. The thesis arrives at describing the combination of duration and non-subjective and supra-individual experience as a polyrhythmic movement.

This dissertation is a philosophical contribution to the theories on trust and on risk communication. The importance of trust in risk communication has been argued for and empirically studied since the 80s. However, there is little agreement on the notion of trust and the precise function of trust. This thesis sets out to study both aspects from a philosophical point of view. The dissertation consists of five essays and an introduction. Essay I is a comment on risk perception theory and the psychometric model in particular. The essay argues that sometimes individuals take risks simply because they are in a vulnerable position and have no other choice. Four factors are identified as crucial in risks from vulnerability: poor outset conditions, lack of reasonable options, hope and liability to disinformation. Essay II addresses the democratic approach to risk communication and the ideal of risk communication as a dialogue between more or less equal stakeholders. The essay develops a typology of different risk communication practices and influence distributions and concludes that the form of risk communication most commonly referred to in the literature is of the most imbalanced kind where all three types of influence falls to the same party. Essay III argues that trust can be understood as comfortable defocusing. Trust as comfortable defocusing means that when a person trusts, he or she is comfortable with letting certain things be in the hands or in the control of the trusted other. Departing from this idea a definition of trust is proposed consisting of three elements: (i) the truster’s comfortable defocusing from the trusted person’s part of caring for X, based on a (ii) belief about the trusted person’s care for X, concerning (iii) something of concern to the truster. Essay IV explores the concept of trustworthiness and under which conditions trust can be betrayed in a morally justified way. It is argued that two aspects are essential for every reasonable notion of trustworthiness: reliability in terms of commitment to trust and predictability in terms of compliance with norms. In order to be untrustworthy in a morally justified way two major conditions need to be fulfilled: first, what is expected from the trustee needs to be either immoral or part of an ongoing immoral or unjust relationship between truster and trustee and, secondly, the trustee must not be in a position to explicitly reject trust. Essay V examines two of the most employed distinctions within the trust literature, that of trust/confidence and of trust/reliance. These distinctions are evaluated against a set of five criteria. It is argued that both these distinctions are employed to cover several distinguishing properties, thus adding to conceptual confusion. / QC 20100712

he subject of this thesis is ethical aspects of decision-making concerning social risks. It is argued that a model for risk management must acknowledge several ethical aspects and, most crucial among these, the individual’s right not to be unfairly exposed to risks. Article I takes as its starting point the demand frequently expressed in the risk literature for consistent risk management. It is maintained that a model focusing on cost-benefit analysis does not respect the rights of the individual. Two alternative models are outlined. They evolve around the separateness of individuals, rights, and fair risk taking. It is claimed that a model that focuses on a fair procedure for risk decisions seems most fruitful to develop. Article II discusses the NIMBY (Not In My Backyard) conflict. The ethical premises behind the negative characterization of the NIMBY concept are investigated. It is argued that a collective weighing of risks and benefits ignores individuals’ rights not to be unfairly exposed to risks in siting scenarios. Article III presents a three-party model tool for ethical risk analysis. The focus in such analysis is a discussion of three parties that are involved in risk decisions: the risk-exposed, the beneficiary, and the decision-maker. Seven crucial ethical questions are discerned by combining these parties pairwise. Article IV discusses a model for procedural justice for risk decisions. Two theories of deliberative democracy are explored. The first focuses on a hypothetical contract, the second argues for the actual inclusion of affected parties. It is maintained that hypothetical reasoning should mainly serve as a guide concerning risk issues that affect people who cannot be included in the decision-making process. Otherwise an interactive dialogical reasoning is to be preferred. Article V explores the claim that there are no real, objective risks – only subjective descriptions of them. It is argued that even though every risk can be described in different ways, involve value judgements and emotions, the ideal of objectivity should not be abandoned. / QC 20100714

The thesis aims at developing approaches to transport policy decisions, based on suggestions and ideas originating from moral philosophy and philosophical decision theory.Paper I analyzes the Swedish transport policy goals, and the problem of combining policygoals with welfare economics. A problem of circularity arises as the Swedish transport policygoals are conflicting, and hence must be subject to trade-offs, while several of the goals themselves entail statements on how to prioritize or restrain goals in case of conflict.Paper II analyzes rationality in road safety policy. Problematic features are identified and discussed. The paper argues that the Swedish road safety goal is rational, since it is actionguiding and achievement-inducing.Paper III includes a model of rational choice under risk with biased risk perception. Under certain plausible conditions, a regulator should raise the population’s risk exposure. By deteriorating the environment the regulator can motivate drivers to choose behaviour that is less biased.Paper IV provides a formal representation of goal systems. The focus is on three properties:consistency, conflict, and coherence. It is argued that consistency is adequately regarded as a property relative to the decision situation or, more specifically, the set of alternatives that the agent faces. Conflict is adequately regarded as a relation over subsets of a given goal systemand should likewise be regarded as relative to the set of alternative that the agent faces.Coherence is given a probabilistic interpretation, based on a support relation over subsets of goal systems.Paper V investigates problems associated with standard deontic logic. A deontic predicate is derived, which avoids some of the major paradoxes in the area. In particular, paradoxes occurring when one obligation is derived by logical necessity from another obligation are dealt with. / QC 20100806

“There is no need to reinvent the wheel” – a cliché, often told when you want to come up with something new that in someway can be connected to something that already exist. This study shows the opposite – that inventions emanate from what is given. It can be a detail, a problem in a thing - a wheel - or a situation that catches the inventor’s attention. It is something that seeks a solution or something that generates an idea, a hint or a clue of something new and useful. The art of invention emerges from the ability and skill to broaden the seeing and put thinking, substance and tradition into motion. An old radio dial generates a new ergonomic steering wheel. The connection of memories between a chestnut, a cello and an early morning at a water pump creates three works of art. The epistemology of this study is based on a dialogue between voices from different times and traditions. Some voices are normative examples, drawn from a dialogue between Swedish inventors. The others are those of philosophers from the Age of Enlightenment, fetched from their original writings. Through that dialogue, perspectives and ideas of inventors and classical philosophers meet and are compared. A deeper understanding thus emerges that shows the essence of invention and in fact the essence of all creative work: i) Freedom – in thought and in action ii) Dialogue - to test and try new ideas and things in the ever changing circumstances. iii) Doubt - not taking established fact and assumptions for granted iv) Action – testing and breaking established praxis and rules. The study also illustrates the need for an alternative scientific form and expression concerning studies in the fields of invention, innovation and other practical work. Invention can not be captured or shaped by exact measurements, concepts, definitions or abstract models. It takes place in the borderland between fact and fiction, where technique, aesthetics and philosophy are one working entity. The strive for knowledge is endless and without limits and it is nurtured by wondering, searching and ambiguity. With inspiration from the dialogue seminar method used within KTH Advanced Programme in Reflective Practice – this study point out the actuality and vitality in using the classical philosophical writings, dialogue and analogical thinking as a scientific method within higher education. / QC 20100826

The present thesis is based on a scientifically-informed, contextualized and historicized reading of Ludwik Fleck. In addition to his monograph, the material studied includes his additional philosophical writings, his internationally-published scientific articles and two, thus-far-unstudied postwar Polish papers related to his Buchenwald experiences. The sources provided by Fleck have been traced back to the time of their origin. Based on the above material, it is argued that, rather than relativizing science and deeply influencing Kuhn, Fleck, attempting to participate in the current debates, is an ardent proponent of science, offering an internal account of its pursuit that accords with his oft-contested epistemic concepts, e.g., Denkzwang, Sinnsehen and Kopplungen. The exposure of his description of the Wassermann reaction discloses a highly selective reading of the sources available at the time, but also reveals its relation to the current debate on Einzelwissenschaften, or the standing of new emerging disciplines versus age-old ones, all occasioned by the remarkable progress of science that has also affected philosophy. The divide between philosophers and scientists on the philosophical implications of modern physics is exposed, as is Fleck’s heuristic use of the latter topic in his epistemology. A more realistic account of his often-valued scientific accomplishments is provided. It is argued that the modern interpretation or received humanist view of Fleck is based on the opposition, at the time Fleck’s monograph was rediscovered, of STS writers to a scientifically-informed reading of his texts. An additional corrective to the received view of Fleck is found in some of his postwar Polish papers related his Buchenwald experiences. The latter might also provide an answer to some of the contradictions inherent in the modern mythology surrounding Fleck. In amply exposing the precarious situation of the time, and the complexity of the ethical issues at stake, Fleck’s papers in fact generate age-old philosophical questions still worth contemplating. / QC 20100826
