But there is a fourth danger as well, and this is the one that interests us most, because it concerns the lines of flight themselves. We may well have presented these lines as a sort of mutation or creation drawn not only in the imagination but also in the very fabric of social reality; we may well have attributed to them the movement of the arrow and the speed of an absolute—but it would be oversimplifying to believe that the only risk they fear and confront is allowingthemselves to be recaptured in the end, letting themselves be sealed in, tied up, reknotted, reterritorialized. They them- selves emanate a strange despair, like an odor of death and immolation, a state of war from which one returns broken: they have their own dangers distinct from the ones previously discussed. This is exactly what led Fitzgerald to say: "I had a feeling that I was standing at twilight on a deserted range, with an empty rifle in my hands and the targets down. No problem set—simply a silence with only the sound of my own breathing. . . . My self-immolation was something sodden-dark."
Why is the line of flight a war one risks coming back from defeated, destroyed, after having destroyed everything one could? This, precisely, is the fourth danger: the line of flight crossing the wall, getting out of the black holes, but instead of connecting with other lines and each time augmenting its valence, turning to destruction, abolition pure and simple, the passion of abolition. Like Kleist's line of flight, and the strange war he wages; like suicide, double sui- cide, a way out that turns the line of flight into a line of death.
