Here is a travel book, literally, a journey in search of shining subjective fragment (s) of water and earth, the stelae of other trips, its enchanted islands. Trip with navigation chart, but without a predetermined plan, which accepts that every trip is-to-be-done, which is essentially unfinished, because there is no other mode of existence possible for the traveler. How do you read this book? And beyond this book, how do you read? It is an experimentation of the fragment, where we do not cling to the One is the author, Another is the one who reads, Another is the work, but where we rather feel (perhaps because of the liquid medium) that everything is mixed. He will be agency, Stéphane Nadaud will say, he who (does not) want to be captain of this ship. Thus, the fragment will never be a fragment of a whole, it will not be a piece of something, or an individual that appears before another, but it will be defined in the immanence of its own self-constitutional and transindividual fluidity, processual assembly, modulation. Against the poison of the Subject, we will try to think about the processes of human subjectivation in its evolution, and in its co-evolution with the other beings / fragments (that travel). Subjective fragment (s) that go from Nietzsche to Foucault, from Heraclitus to Eisenstein, from Pessoa to Kafka, from Deleuze to Guattari (and from Guattari to Deleuze), from Chamfort to Joubert. Against the thought of the lack, affirm subjective fragment (s), since there is no lack except in artificial paradises. Against the abstention of the scholar who, for fear of being crushed, does not dare to touch even the monument, the gray task of the genealogist who takes the monument as a document, and vice versa, and accepts to manipulate with courage, get his hand in the dough, combining play and rigor, chance and necessity. Like Nietzsche, like Nadaud on this trip, like the thought itself.
