Until now, Fabrice Clément’s teaching has been addressed to sociologists or philosophers. In both cases, interdisciplinarity and conceptual rigour are emphasized. His objective is to present various bridges which connect disciplines and show that the routes they open are worth taking. Society and cognition. The natural bases of the Social The objective of this set of lectures, intended for advanced students in sociology, is to show in what sense cognitive sciences are relevant for social sciences. The starting point is the acknowledgment of the fact that any sociological analysis needs a convincing model of the human mind. Most sociological paradigms, and in particular methodological individualism and genetic structuralism, use a conception of the cognitive and affective mechanisms that our social interactions require that is too schematic. The course introduces a cognitive approach, presents illustrations coming from cognitive anthropology, social and developmental psychology, and lays the foundations of a theory of the epidemiology of beliefs. This course was first given at the department of sociology, University of Geneva. Philosophy et cognitive sciences. Towards a cognitive philosophy This set of lectures is essentially intended for advanced students in philosophy, but it is also accessible to psychologists and students working with neurosciences. Its purpose is to demonstrate to what extent researches done in the field of cognitive sciences (essentially neurosciences, cognitive, social and developmental psychology and philosophy of mind) tend to modify some philosophical conceptions. The content is organised around key notions such as reason, consciousness, emotions, or identity. Once the traditional meaning of these concepts has been recalled, contemporary cognitive researches are introduced to show how they are shaking up conceptions that are taken for granted. One of the goals of this class is to familiarize students with the experimental approach and to encourage them to take into account the work conducted in contemporary cognitive sciences. This course was first given at the department of philosophy, University of Neuchâtel.
