Philosophy and Sinology, François Jullien presents here a lecture he gave to business leaders and in the field of management. On one hand, the European view of effectiveness is associated with the creation of models and purpose, leading to actions that can reach the level of heroism; on the other hand, Chinese thinking about indirect and discreet efficiency relies on the potential of the situation and triggers "silent transformations" that occur without drawing attention and do not even attain the status of an event. This difference serves to examine the nature of effectiveness, specifically how human intervention manages to align with the tendencies of things and how it integrates into them. This approach thus seeks to explore the art of influencing situations and the practice of philosophy.
