““But if man genuinely produces man, it is precisely not through work and it's concrete results, not even the 'work on oneself' so widely praised in recent times, let alone through the alternatively invoked phenomena of 'interaction' or 'communication': it is through life in forms of practice. Practice is defined here as any operation that provides or improves the actor's qualification for the next performance of the same operation, whether it is declared as practice or not.””
