What is philosophy today — philosophical activity, I mean — if it is not the critical work that thought brings to bear on itself? In what does it consist, if not in the endeavor to know how and to what extent it might be possible to think differently, instead of legitimating what is already known? There is always something ludicrous in philosophical discourse when it tries, from the outside, to dictate to others, to tell them where their truth is and how to find it, or when it works up a case against them in the language of naive positivity. But it is entitled to explore what might be changed, in its own thought, through the practice of a knowledge that is foreign to it.
