I always felt I had to stay in contact with the world, with my world.
Ever since Marx, philosophy must lead to action.
Otherwise it is irrelevant.
So a philosopher does what he has to do,
then sits down at his desk, wherever it is,
and “retakes the thread of his anger,” as Valéry once said.
The distractions don’t matter as long as I could retake the thread of my anger,
angers against this system, against all those who believe that they have a right to be greedy,
who feel they are superior to others,
like the French in Algeria, in Madagascar,
the Americans in Haiti, in Puerto Rico, the whites in black New York,
the Dulleses in Guatemala or Egypt.
Philosophers must be angry, and in this world, stay angry.
–Jean-Paul Sartre
