Abstract: This paper reassesses the critical function of philosophy in a globalized world gripped by recurrent crises. What does it mean to orient oneself in thinking? The paper suggests that philosophy is the diagnosis of becomings and transformations. Philosophy cannot be restricted to a closed field or discipline since it is discussion, experimentation. Philosophy relates to the street, to society, to the struggles that bring life to existence: it relates to non-philosophy, to its outside. Starting with Marx in the 19th century, philosophy has taken a new trajectory: the critique of the present has become critique of capitalism, that is to say of the kind of temporality to which we belong. Throughout the 20th and the 21st century there is a conspicuous number of non-philosophical experiences that have radically contributed to transform and enrich the philosophical discourse. They have permitted the emergence of new objects of inquiry, of new problems and problematizations: among them we can count the importance of feminism, of the Italian Operaism, of the French philosophies of Michel Foucault and Gilles Deleuze, to only name a few ones.
