Practices and Thought in Michel Foucault s Philosophy The present thesis examines Michel Foucault s (1926-1984) notion of practice and argues that it is an essential concept in his philosophy, especially in his analysis of knowledge, power and ethics. The thesis reveals a previously neglected chronological and methodological unity in Foucault s work. The first chapter clarifies Foucault s philosophy by outlining it according to four central themes. First, the main philosophical goal of his historical studies is to analyse how human subjects have become objects of their own thinking. Second, this goal calls for methodological precaution to avoid all anthropological universals. Third, Foucault s studies are directed towards fields of practices. Fourth, the analysis of practices is executed along three axes: knowledge, power and ethics. The second chapter concerns the notion of practice in Foucault s archaeological method. Foucault s archaeological analysis is not directed towards objects and subjects as such, but to the way that the rules of discursive practice form them in the discourse. Many commentators have neglected Foucault s concept of practice when discussing his ideas concerning rules of discourse and limits of knowledge. I argue that Foucault s analysis concerning the limits of knowledge relates to local and contingent rules of discursive practice, not to transcendental rules of thinking in general. The third chapter deals with power relations and practices. I clarify Foucault s concept of dispositif by defining it as a functional ensemble of practices, and argue that this concept is crucial to his understanding of power relations. I stress a conceptual definition, which separates relations of power from the practices of government and show that the latter is based on the idea that power relations are integrated into practices. This conceptual clarification also helps in understanding Foucault s critique concerning modern practices of power. The fourth chapter examines Foucault s way of perceiving ethics as a practice. He separates three essential dimensions in morals: moral codes, moral behaviour and practices of self. His ethics concern practices of self and he studies how these practices have constituted different relations that subjects have to themselves, to others and to their societies. I argue that Foucault s own ethical views can be found in the ideas on the importance of practices of self in the modern world, and emphasize that these ideas should be connected to his views concerning the tradition of the Enlightenment, and to his own political action.

Developmental origins of physiological stress reactivity

The model of developmental origins of health and disease proposes that organisms during fetal period utilize cues that enable their adaptation in the postnatal environment they are likely to live, having short-term advantages when trying to survive in environment but simultaneously in the long run have costs for health. A large body of epidemiological research has found that low birth weight, a marker of intrauterine conditions, is associated with cardiovascular (CV) disease. Since the reported associations of birth weight with normal variation in the resting blood pressure (BP), a major predictor of CV disease risk, have been modest, a key candidate mediating the link has been CV and hypothalamus-pituitary-adrenal axes (HPAA) reactivity to stress. In addition, not only weight at birth but also gestational age and early postnatal growth may have independent associations to stress reactivity. The aim of this thesis was to investigate whether pre- and postnatal growth and gestational age are associated with CV and HPAA activity before, during and after stress in childhood and in late adulthood. Altogether 287 men and women aged 60-70 and 299 boys and girls aged 7-9 underwent Trier Social Stress Test. Several indices of HPAA and CV were measured and birth size and gestational age were obtained from birth records. Results showed that low birth weight was associated with low HPAA activity during psychosocial stress, and rapid gain in BMI during years 7-11 was related to heightened stress reactivity to psychosocial stress. Size at birth in children and gestational age and early postnatal (0-2 years) gain in height in adults were associated with CV stress responses; however, in a sex-specific manner. Given that CV stress responses and HPAA activity are markers of CV disease vulnerability, our results may partly explain the associations between early environment and later CV disease.
