“It has been held that, since its essential normativity cannot be accommodated within the natural sciences, we might be forced to throw the concept of action and with it action concepts on the trash heap of outdated theories. With action concepts a logical basis of first person thought disappears. Renouncing action concepts is a form of self-annihilation: logical self-annihilation. It annihilates a source of the power to think and say 'I'.”
