Background: Adenosine is a potent sleep-promoting substance, and one of its targets is the basal forebrain. Fairly little is known about its mechanism of action in the basal forebrain and about the receptor subtype mediating its regulating effects on sleep homeostasis. Homeostatic deficiency might be one of the causes of the profoundly disturbed sleep pattern in major depressive disorder, which could explain the reduced amounts of delta-activity-rich stages 3 and 4. Since major depression has a relatively high heritability, and on the other hand adenosine regulates sleep homeostasis and might also be involved in mood modulation, adenosine-related genes should be considered for their possible contribution to a predisposition for depression and disturbed sleep in humans. Depression is a complex disorder likely involving the abnormal functioning of several genes. Novel target genes which could serve as the possible common substrates for depression and comorbid disturbed sleep should be identified. In this way specific brain areas related to sleep regulation should be studied by using animal model of depression which represents more homogenous phenotype as compared to humans. It is also important to study these brain areas during the development of depressive-like features to understand how early changes could facilitate pathophysiological changes in depression. Aims and methods: We aimed to find out whether, in the basal forebrain, adenosine induces recovery non-rapid eye movement (NREM) sleep after prolonged waking through the A1 or/and A2A receptor subtype. A1 and A2A receptor antagonists were perfused into the rat basal forebrain during 3 h of sleep deprivation, and the amount of NREM sleep and delta power during recovery NREM sleep were analyzed. We then explored whether polymorphisms in genes related to the metabolism, transport and signaling of adenosine could predispose to depression accompanied by signs of disturbed sleep. DNA from 1423 individuals representative of the Finnish population and including controls and cases with depression, depression accompanied by early morning awakenings and depression accompanied by fatigue, was used in the study to investigate the possible association between polymorphisms from adenosine-related genes and cases. Finally to find common molecular substrates of depression and disturbed sleep, gene expression changes were investigated in specific brain areas in the rat clomipramine model of depression. We focused on the basal forebrain of 3-week old clomipramine-treated rats which develop depressive-like symptoms later in adulthood and on the hypothalamus of adult female clomipramine-treated rats. Results: Blocking of the A1 receptor during sleep deprivation resulted in a reduction of the recovery NREM sleep amount and delta power, whereas A2A receptor antagonism had no effect. Polymorphisms in adenosine-related genes SLC29A3 (equilibrative nucleoside transporter type 3) in women and SLC28A1 (concentrative nucleoside transporter type 1) in men associated with depression alone as well as when accompanied by early morning awakenings and fatigue. In Study III the basal forebrain of postnatal rats treated with clomipramine displayed disturbances in gamma-aminobutyric acid (GABA) receptor type A signaling, in synaptic transmission and possible epigenetic changes. CREB1 was identified as a common transcription denominator which also mediates epigenetic regulation. In the hypothalamus the major changes included the expression of genes in GABA-A receptor pathway, K+ channel-related, glutamatergic and mitochondrial genes, as well as an overexpression of genes related to RNA and mRNA processing. Conclusions: Adenosine plays an important role in sleep homeostasis by promoting recovery NREM sleep via the A1 receptor subtype in the basal forebrain. Also adenosine levels might contribute to the risk of depression with disturbed sleep, since the genes encoding nucleoside transporters showed the strongest associations with depression alone and when accompanied by signs of disturbed sleep in both women and men. Sleep and mood abnormalities in major depressive disorder could be a consequence of multiple changes at the transcriptional level, GABA-A receptor signaling and synaptic transmission in sleep-related basal forebrain and the hypothalamus.

Polyamines are organic polycations that participate in various physiological functions, including cell proliferation, differentiation and apoptosis. Cellular polyamines originate from endogenous biosynthesis and exogenous sources. Their subcellular pool is under strict control, achieved by regulating their uptake and metabolism. Polyamine-induced proteins called antizymes (AZ) act as key regulators of intracellular polyamine concentration. They regulate both the transport of polyamines and the activity and degradation of ornithine decarboxylase (ODC), the rate-limiting enzyme in polyamine biosynthesis. AZs themselves are negatively regulated by antizyme inhibitor (AZIN). AZIN functions as a positive regulator of cellular polyamine homeostasis, which by binding to AZs reactivates ODC and induces the uptake of polyamines. In various pathological conditions, including cancer, polyamine levels are misregulated. Polyamine homeostasis has therefore become an attractive target for therapeutic interventions and it is thus crucial to characterize the molecular basis underlying the homeostatic regulation. A novel human AZIN-resembling protein was previously identified in our group. The purpose of this study was to elucidate the function and distribution of this protein, termed as an antizyme inhibitor 2 (AZIN2). According to my results, AZIN2 functions as a novel regulator of polyamine homeostasis. It shows no enzymatic activity, but instead it binds AZs and negates their activity, which subsequently leads to reactivation of ODC and inhibition of its degradation. Expression of AZIN2 is restricted to terminally differentiated cells, such as mast cells (MC) and neurosecretory cells. In these actively secreting cell types, AZIN2 localizes to subcellular vesicles or granules where its function is important for the vesicle-mediated secretion. In MCs, AZIN2 localizes to the serotonin-containing subset of MC granules, and its expression is coupled to MC activation. The functional role of polyamines as potential mediators of MC activity was also investigated, and it was observed that the secretion of serotonin is selectively dependent on activation of ODC. In neurosecretory cells, AZIN2-positive vesicles localize mainly to the trans-Golgi network (TGN). Depletion of AZIN2 or cellular polyamines causes selective fragmentation of the TGN and retards secretion of proteins. Since addition of exogenous polyamines reverses these effects, the data indicate that AZIN2 and its downstream effectors, polyamines, are functionally implicated in the regulation of secretory vesicle transport. My studies therefore reveal a novel function for polyamines as modulators of both constitutive and regulated secretion. Based on the results, I propose that the role of AZIN2 is to act as a local in situ activator of polyamine biosynthesis.

Heredity explains a major part of the variation in calcium homeostasis and bone strength, and the susceptibility to osteoporosis is polygenetically regulated. Bone phenotype results from the interplay between lifestyle and genes, and several nutritional factors modulate bone health throughout life. Thus, nutrigenetics examining the genetic variation in nutrient intake and homeostatic control is an important research area in the etiology of osteoporosis. Despite continuing progress in the search for candidate genes for osteoporosis, the results thus far have been inconclusive. The main objective of this thesis was to investigate the associations of lactase, vitamin D receptor (VDR), calcium sensing receptor (CaSR) and parathyroid hormone (PTH) gene polymorphisms and lifestyle factors and their interactions with bone health in Finns at varying stages of the skeletal life span. Markers of calcium homeostasis and bone remodelling were measured from blood and urine samples. Bone strength was measured at peripheral and central bone sites. Lifestyle factors were assessed with questionnaires and interviews. Genetic lactase non-persistence (the C/C-13910 genotype) was associated with lower consumption of milk from childhood, predisposing females in particular to inadequate calcium intake. Consumption of low-lactose milk and milk products was shown to decrease the risk for inadequate calcium intake. In young adulthood, bone loss was more common in males than in females. Males with the lactase C/C-13910 genotype may be more susceptible to bone loss than males with the other lactase genotypes, although calcium intake predicts changes in bone mass more than the lactase genotype. The BsmI and FokI polymorphisms of the VDR gene were associated with bone mass in growing adolescents, but the associations weakened with age. In young adults, the A986S polymorphism of the calcium sensing receptor gene was associated with serum ionized calcium concentrations, and the BstBI polymorphism of the parathyroid gene was related to bone strength. The FokI polymorphism and sodium intake showed an interaction effect on urinary calcium excretion. A novel gene-gene interaction between the VDR FokI and PTH BstBI gene polymorphisms was found in the regulation of PTH secretion and urinary calcium excretion. Further research should be carried out with more number of Finns at varying stages of the skeletal life span and more detailed measurements of bone strength. Research should concern mechanisms by which genetic variants affect calcium homeostasis and bone strength, and the role of diet-gene and gene-gene interactions in the pathogenesis of osteoporosis.

En route from Birmingham to Syria in 2013, British-Jihadi neophytes aged 22, Yusuf Sarwar and Mohammed Ahmed purchased two books via Amazon to prepare for their mission in Syria after joining ISIS: The Koran for Dummies and Islam for Dummies. Journalists were swift to disparage their reading. The book’s author, Princeton University campus imam, Sohaib Nazeer Sultan remarked “Even though they may have ordered it, I don't think they read it.” In 1933, aged 27, Adolf Eichmann moved to Berlin to join the Sicherheitsdienst SD whereupon he read Immanuel Kant’s book the Kritik der praktischen Vernunft (The Critique of Practical Reason) for the first time. After his trial in Jerusalem, Hannah Arendt of course dismissed Eichmann’s reading of the German philosopher as thoroughly vacuous. Ever since, writers have sought to undermine the veracity of Eichmann’s account. The global Jihadis are illiterate, a journalist recently commented: they’re not well read in the Qur’an, and if they have read it, they have thoroughly misunderstood it. He cited as evidence Abdul Raqib Amin’s YouTube rhetorical: Forget everyone. Read the Koran, read the instruction of life. Find out what is jihad. Eichmann on the other hand was not illiterate in his youth. Before Berlin, he had already read Kant’s Groundwork of the Metaphysics of Morals ; he would also re-read the Critique of Practical Reason, and from his testimony and terminology we can infer he was familiar with Kantian concepts that extend beyond both books...

Within coronial investigations, pathologists are called upon to given evidence as to cause of death. This evidence is given great weight by the coroners; after all, scientific ‘truth’ is widely deemed to be far more reliable than legal ‘opinion’. The purpose of this paper is to examine the ontological and epistemological status of that evidence, from the perspectives of both the pathologists and the coroners. As part of an Australian Research Council Linkage Grant, interviews were conducted with seven pathologists and 10 coroners from within the Queensland coronial system. Contrary to expectations, and the work of philosophers of science, such as Feyerabend (1975), pathologists did not present their findings in terms of unequivocal facts or objective truths relating to causes of death. Rather, their evidence was largely presented as ‘educated opinion’ based upon ‘the weight of evidence’. It was actually the coroners who translated that opinion into ‘medical fact’ within the proceedings of their death investigations, arguably as a consequence of the administrative necessity to reach a clear-cut finding as to cause of death, and on the basis of their own understanding of the ontology of medical knowledge. These findings support Latour’s (2010) claim that law requires a fundamentally different epistemology to science, and that science is not entirely to blame for the extravagant truth-claims made on its behalf

What is a miracle and what can we know about miracles? A discussion of miracles in anglophone philosophy of religion literature since the late 1960s. The aim of this study is to systematically describe and philosophically examine the anglophone discussion on the subject of miracles since the latter half of the 1960s. The study focuses on two salient questions: firstly, what I will term the conceptual-ontological question of the extent to which we can understand miracles and, secondly, the epistemological question of what we can know about miracles. My main purpose in this study is to examine the various viewpoints that have been submitted in relation to these questions, how they have been argued and on what presuppositions these arguments have been based. In conducting the study, the most salient dimension of the various discussions was found to relate to epistemological questions. In this regard, there was a notable confrontation between those scholars who accept miracles and those who are sceptical of them. On the conceptual-ontological side I recognised several different ways of expressing the concept of miracle . I systematised the discussion by demonstrating the philosophical boundaries between these various opinions. The first and main boundary was related to ontological knowledge. On one side of this boundary I placed the views which were based on realism and objectivism. The proponents of this view assumed that miraculousness is a real property of a miraculous event regardless of how we can perceive it. On the other side I put the views which tried to define miraculousness in terms of subjectivity, contextuality and epistemicity. Another essential boundary which shed light on the conceptual-ontological discussion was drawn in relation to two main views of nature. The realistic-particularistic view regards nature as a certain part of reality. The adherents of this presupposition postulate a supernatural sphere alongside nature. Alternatively, the nominalist-universalist view understands nature without this kind of division. Nature is understood as the entire and infinite universe; the whole of reality. Other, less important boundaries which shed light on the conceptual-ontological discussion were noted in relation to views regarding the laws of nature, for example. I recognised that the most important differences between the epistemological approaches were in the different views of justification, rationality, truth and science. The epistemological discussion was divided into two sides, distinguished by their differing assumptions in relation to the need for evidence. Adherents of the first (and noticeably smaller) group did not see any epistemological need to reach a universal and common opinion about miracles. I discovered that these kinds of views, which I called non-objectivist, had subjectivist and so-called collectivist views of justification and a contextualist view of rationality. The second (and larger) group was mainly interested in discerning the grounds upon which to establish an objective and conclusive common view in relation to the epistemology of miracles. I called this kind of discussion an objectivist discussion and this kind of approach an evidentialist approach. Most of the evidentialists tried to defend miracles and the others attempted to offer evidence against miracles. Amongst both sides, there were many different variations according to emphasis and assumption over how they saw the possibilities to prove their own view. The common characteristic in all forms of evidentialism was a commitment to an objectivist notion of rationality and a universalistic notion of justification. Most evidentialists put their confidence in science in one way or another. Only a couple of philosophers represented the most moderate version of evidentialism; they tried to remove themselves from the apparent controversy and contextualised the different opinions in order to make some critical comments on them. I called this kind of approach a contextualising form of evidentialism. In the final part of the epistemological chapter, I examined the discussion about the evidential value of miracles, but nothing substantially new was discovered concerning the epistemological views of the authors.

With increasing speed, the emerging discipline of critical Indigenous studies is expanding and demarcating its territory from Indigenous studies through the work of a new generation of Indigenous scholars. Critical Indigenous Studies makes an important contribution to this expansion, disrupting the certainty of disciplinary knowledge produced in the twentieth century, when studying Indigenous peoples was primarily the domain of non-Indigenous scholars. Aileen Moreton-Robinson's introductory essay provides a context for the emerging discipline. The volume is organized into three sections: the first includes essays that interrogate the embedded nature of Indigenous studies within academic institutions; the second explores the epistemology of the discipline; and the third section is devoted to understanding the locales of critical inquiry and practice. Each essay places and contemplates critical Indigenous studies within the context of First World nations, which continue to occupy Indigenous lands in the twenty-first century. The contributors include Aboriginal, Metis, Maori, Kanaka Maoli, Filipino-Pohnpeian, and Native American scholars working and writing through a shared legacy born of British and later U.S. imperialism. In these countries, critical Indigenous studies is flourishing and transitioning into a discipline, a knowledge/power domain where distinct work is produced, taught, researched, and disseminated by Indigenous scholars.

Science and the Scientist's Social Responsibility. Joseph Ben-David's, Roger Sperry's and Knut Erik Tranøy's Views of Science and the Scientist's Social Responsibility The aim of the study was to investigate, whether or not there is any connection between Jewish sociologist Joseph Ben-David's, American neuroscientist Roger Sperry's and Norwegian philosopher Knut Erik Tranøy's views of science and views of the scientist's social responsibility. The sources of information were their writings concerning this topic. Ben-David has a classical view of science. He thinks that the Mertonian norms of scientific activity, first written in 1942, are still valid in modern science. With the help of these norms Ben-David defends the view that science is morally neutral. Ben-David thinks that a scientist has a limited social responsibility. A scientist only reports on the new results, but he is not responsible for applying the results. In any case Ben-David's ideas are no longer valid. Sperry has a scientistic view of science. According to Sperry, science is the source of moral norms and also the best guide for moral action. The methods of natural sciences "show" how to solve moral problems. A scientist's personal views of science and social responsibility are not important. However Sperry's view is very problematic on the ethical side. Tranøy stresses the scientist's social responsibility. A scientist has common norms with the society from with he or she comes. This is why a scientist has the right, and also the responsibility, to discuss social and ethical questions between science and society. Tranøy's view has some ethical and practical problems, but it is valid in principle. Finally, Ben-David's, Sperry's and Tranøy's views of both science and the scientist's social responsibility have a connection: the view of science corresponds to the certain view of scientist's social responsibility. The result of this study is: Ben-David's, Sperry's and Tranøy's view of science have an ethical starting point as its fundamental presupposition, which include certain views of scientific knowledge, good and the scientist's ethical responsibilities. The connection between Ben-David's, Sperry's and Tranøy's views of science and views of the scientist's social responsibility means that their views of epistemology, meta-ethics and the scientist's ethical responsibilities have a connection to their views of the scientist's social responsibility. The results of this study can help the scientific community to organize the social responsibility of a scientist and deepen the conversation concerning the scientist's social responsibility.

The dissertation consists of four essays and a comprehensive introduction that discusses the topics, methods, and most prominent theories of philosophical moral psychology. I distinguish three main questions: What are the essential features of moral thinking? What are the psychological conditions of moral responsibility? And finally, what are the consequences of empirical facts about human nature to normative ethics? Each of the three last articles focuses on one of these issues. The first essay and part of the introduction are dedicated to methodological questions, in particular the relationship between empirical (social) psychology and philosophy. I reject recent attempts to understand the nature of morality on the basis of empirical research. One characteristic feature of moral thinking is its practical clout: if we regard an action as morally wrong, we either refrain from doing it even against our desires and interests, or else feel shame or guilt. Moral views seem to have a conceptual connection to motivation and emotions – roughly speaking, we can’t conceive of someone genuinely disapproving an action, but nonetheless doing it without any inner motivational conflict or regret. This conceptual thesis in moral psychology is called (judgment) internalism. It implies, among other things, that psychopaths cannot make moral judgments to the extent that they are incapable of corresponding motivation and emotion, even if they might say largely the words we would expect. Is internalism true? Recently, there has been an explosion of interest in so-called experimental philosophy, which is a methodological view according to which claims about conceptual truths that appeal to our intuitions should be tested by way of surveys presented to ordinary language users. One experimental result is that the majority of people are willing to grant that psychopaths make moral judgments, which challenges internalism. In the first article, ‘The Rise and Fall of Experimental Philosophy’, I argue that these results pose no real threat to internalism, since experimental philosophy is based on a too simple conception of the relationship between language use and concepts. Only the reactions of competent users in pragmatically neutral and otherwise conducive circumstances yield evidence about conceptual truths, and such robust intuitions remain inaccessible to surveys for reasons of principle. The epistemology of folk concepts must still be based on Socratic dialogue and critical reflection, whose character and authority I discuss at the end of the paper. The internal connection between moral judgment and motivation led many metaethicists in the past century to believe along Humean lines that judgment itself consists in a pro-attitude rather than a belief. This expressivist view, as it is called these days, has far-reaching consequences in metaethics. In the second essay I argue that perhaps the most sophisticated form of contemporary expressivism, Allan Gibbard’s norm-expressivism, according to which moral judgments are decisions or contingency plans, is implausible from the perspective of the theory of action. In certain circumstances it is possible to think that something is morally required of one without deciding to do so. Morality is not a matter of the will. Instead, I sketch on the basis of Robert Brandom’s inferentialist semantics a weak form of judgment internalism, according to which the content of moral judgment is determined by a commitment to a particular kind of practical reasoning. The last two essays in the dissertation emphasize the role of mutual recognition in the development and maintenance of responsible and autonomous moral agency. I defend a compatibilist view of autonomy, according to which agents who are unable to recognize right and wrong or act accordingly are not responsible for their actions – it is not fair to praise or blame them, since they lacked the relevant capacity to do otherwise. Conversely, autonomy demands an ability to recognize reasons and act on them. But as a long tradition in German moral philosophy whose best-known contemporary representative is Axel Honneth has it, both being aware of reasons and acting on them requires also the right sort of higher-order attitudes toward the self. Without self-respect and self-confidence we remain at the mercy of external pressures, even if we have the necessary normative competence. These attitudes toward the self, in turn, are formed through mutual recognition – we value ourselves when those who we value value us. Thus, standing in the right sort of relations of recognition is indirectly necessary for autonomy and moral responsibility. Recognition and valuing are concretely manifest in actions and institutions, whose practices make possible participation on an equal footing. Seeing this opens the way for a kind of normative social criticism that is grounded in the value of freedom and automomy, but is not limited to defending negative rights. It thus offers a new way to bridge the gap between liberalism and communitarianism.

The first year at the university is critical in shaping the student s future academic development. Student integration has been shown to affect learning, motivation, persistence, and ultimately, graduation. Most importantly, however, integration affects how students academic expertise develops. In this study a social-psychological assumption was made: one cannot grow into academic expertise in isolation, without interaction with teachers and peers. Integration happens via engagement. In this research, social and academic integration among Finnish freshmen was studied. How much did freshmen interact with their teachers and peers; how interested did they think their teachers were in students; how committed did they feel; and how did they assess their own academic development? In addition to integration, students were asked about their identification with the university and the frequency of actual contacts with teachers and peers. Lastly, students personal epistemologies were studied to see if they were related to integration or frequency of contacts. The data was collected at the University of Helsinki in the autumn of 2001 and spring of 2002 at three faculties: the faculty of Social Sciences, Humanities and Science. In the autumn, 270 freshmen, and in the spring, 400 freshmen, completed the questionnaire. In addition to the cross-sectional data a longitudinal data was formed from 77 of the respondents. The results showed differences in how students were integrated. Freshmen at the faculty of Science were the least integrated whereas freshmen at the faculty of Humanities were the most integrated. Identification to the university was positively related to integration. The frequency of contacts with faculty and peers was positively related to integration and identification. A more developed personal epistemology was also positively related to integration and frequency of contacts. Differences were also found between the sexes in frequency of peer interaction and level of epistemology. This study has both theoretical and practical implications. Positive correlations between integration, identification, frequency of contacts and personal epistemology were found. The guiding assumption of the significance of social interaction was thus supported. The practical relevance of the study is for how teaching is carried out. In this data, over 50% of new university students at the end of their first year said they had never received feedback from an exam, never had a discussion with their teacher about a scientific topic, and had never discussed with a teacher how their studies were going.

The doctoral dissertation Critic Einari J. Vehmas and Modern Art deals with one of the central figures of the Finnish art scene and his work as an art critic, art museum curator and cultural critic. The main body of research material consists of the writings of Einari J. Vehmas (1902 1980) from 1937 to the late 1960s. Vehmas wrote art reviews for magazines, and from the year 1945 he was a regular art critic for one of the major newspapers in Finland. Vehmas was heavily inclined towards French literature and visual arts. Marcel Proust and Charles Baudelaire influenced his views on the nature of art from the late 1920s onwards. Vehmas is commonly regarded as the most influential art critic of post-war Finland. His writings have been referred to and cited in numerous research papers on Finnish 20th-century art. A lesser known aspect of his work is his position as the deputy director of the Ateneum Art Museum, the Finnish national gallery. Through his art museum work, his opinions also shaped the canon of modern art considered particularly Finnish following the second world war. The main emphasis of the dissertation is on studying Vehmas s writings, but it also illustrates the diversity of his involvement in Finnish cultural life through biographical documents. The long chronological span of the dissertation emphasises how certain central themes accumulate in Vehmas s writings. The aim of the dissertation is also to show how strongly certain philosophical and theoretical concepts from the early 20th century, specifically Wassily Kandinsky s principle of inner necessity and Henri Bergson s epistemology highlighting intuition and instinct, continued to influence the Finnish art discourse even in the early 1960s, in part thanks to the writings of Vehmas. Throughout his production, Vehmas contemplated the state and future of modern art and humanity. Vehmas used a colourful, vitalistic rhetoric to emphasise the role of modern art as a building block of culture and humanity. At the same time, however, he was a cultural pessimist whose art views became infused with anxiety, a sense of loss, and a desire to turn his back on the world.

In view of the current fragmentation in management and organisation studies, we argue that there is a need to elaborate techniques that help reconcile contradictory and superficially incommensurable standpoints. For this purpose, we draw on ‘pre-modern’ Aristotelian epistemological and methodological sources, particularly the idea of ‘saving the appearances’ (SA), not previously introduced into organisation studies. Using SA as our starting point, we outline a methodology that helps to develop reasonable and acceptable intermediary positions in contemporary debates between ‘modernism’ and ‘post-modernism’. We illustrate the functioning of SA in the case of three issues in the philosophy of science where ‘modernist’ and ‘post-modernist’ scholars seem to have incommensurable standpoints: the nature of scientific knowledge; the conception of causality; and the epistemology of practice. We show in particular how to use the logics of ‘qualification’, ‘new conception’, and ‘complementary combination’ to form the basis for mediating positions which could then be accepted by less extreme proponents of both ‘modernism’ and ‘postmodernism’.

The subject and methodology of biblical scholarship has expanded immense-ly during the last few decades. The traditional text-, literary-, source- and form-critical approaches, labeled historical-critical scholarship , have faced the challenge of social sciences. Various new literary, synchronic readings, sometimes characterized with the vague term postmodernism, have in turn challenged historicalcritical, and social-scientific approaches. Widened limits and diverging methodologies have caused a sense of crisis in biblical criticism. This metatheoretical thesis attempts to bridge the gap between philosophical discussion about the basis of biblical criticism and practical academic biblical scholarship. The study attempts to trace those epistemological changes that have produced the wealth of methods and results within biblical criticism. The account of the cult reform of King Josiah of Judah as reported in 2 Kings 22:1 23:30 serves as the case study because of its importance for critical study of the Hebrew Bible. Various scholarly approaches embracing 2 Kings 22:1 23:30 are experimentally arranged around four methodological positions: text, author, reader, and context. The heuristic model is a tentative application of Oliver Jahraus s model of four paradigms in literary theory. The study argues for six theses: 1) Our knowledge of the world is con-structed, fallible and theory-laden. 2) Methodological plurality is the neces-sary result of changes in epistemology and culture in general. 3) Oliver Jahraus s four methodological positions in regard to literature are also an applicable model within biblical criticism to comprehend the methodological plurality embracing the study of the Hebrew Bible. 4) Underlying the methodological discourse embracing biblical criticism is the epistemological ten-sion between the natural sciences and the humanities. 5) Biblical scholars should reconsider and analyze in detail concepts such as author and editor to overcome the dichotomy between the Göttingen and Cross schools. 6) To say something about the historicity of 2 Kings 22:1 23:30 one must bring together disparate elements from various disciplines and, finally, admit that though it may be possible to draw some permanent results, our conclusions often remain provisional.

This monograph describes the emergence of independent research on logic in Finland. The emphasis is placed on three well-known students of Eino Kaila: Georg Henrik von Wright (1916-2003), Erik Stenius (1911-1990), and Oiva Ketonen (1913-2000), and their research between the early 1930s and the early 1950s. The early academic work of these scholars laid the foundations for today's strong tradition in logic in Finland and also became internationally recognized. However, due attention has not been given to these works later, nor have they been comprehensively presented together. Each chapter of the book focuses on the life and work of one of Kaila's aforementioned students, with a fourth chapter discussing works on logic by authors who would later become known within other disciplines. Through an extensive use of correspondence and other archived material, some insight has been gained into the persons behind the academic personae. Unique and unpublished biographical material has been available for this task. The chapter on Oiva Ketonen focuses primarily on his work on what is today known as proof theory, especially on his proof theoretical system with invertible rules that permits a terminating root-first proof search. The independency of the parallel postulate is proved as an example of the strength of root-first proof search. Ketonen was to our knowledge Gerhard Gentzen's (the 'father' of proof theory) only student. Correspondence and a hitherto unavailable autobiographic manuscript, in addition to an unpublished article on the relationship between logic and epistemology, is presented. The chapter on Erik Stenius discusses his work on paradoxes and set theory, more specifically on how a rigid theory of definitions is employed to avoid these paradoxes. A presentation by Paul Bernays on Stenius' attempt at a proof of the consistency of arithmetic is reconstructed based on Bernays' lecture notes. Stenius correspondence with Paul Bernays, Evert Beth, and Georg Kreisel is discussed. The chapter on Georg Henrik von Wright presents his early work on probability and epistemology, along with his later work on modal logic that made him internationally famous. Correspondence from various archives (especially with Kaila and Charlie Dunbar Broad) further discusses his academic achievements and his experiences during the challenging circumstances of the 1940s.
