À bout de souffle / Breathless is first of all the title of one of Godard’s films. Apart from that, this phrase links at least the two moments of subjectivity and flight. The subject is essentially a breathing subject. Strictly speaking, subjectivity comprises breathlessness. The subject does not breathe only to maintain itself, to survive. Just as flight in the strong sense of the word reactivated by Deleuze, can only be a flight forward, to breathe means to open oneself breathlessly to a future that remains undetermined, contingent. The subject is breathless because it involves itself with the incommensurable which can only be blindly affirmed because it marks the limit of what is knowable. To breathe means already to be out of breath, opened to the indeterminacy which life is. One does not live simply by breathing. The life of a subject begins with the acceleration of breathing beyond the vegetative imperative. Breathlessly, the subject gives itself its future by receiving it as a surprise.
