ABSTRACT
This part introduction presents an overview of the key concepts discusses in the subsequent chapter. It is divided into three sections which we believe treat important and representative aspects of current praxiology: Individual Action and Collective Action, Actions, Objects and Space, Actions and Knowledge. The part deals with a double approach to action, individualistic or holistic. J. P. Minary deals with the organization and the efficiency of social work. J. L. Dumont deals with the possibilities of the application of praxiology to social work. The part is devoted to acts, objects and space. B. Lefort analyzes the relationships between the tool, thought and action. The part concerns the relations between actions and cognition. F. Girandola questions the predictability of certain models frequently used in social psychology, models based on early theories such as attitudes as well as more recent ones such as the theories of Causal Attribution, Locus of Control, Cognitive Dissonance and Engagement.
