Formerly a skipper and trainer of sailing instructors in the Glenan Islands, Gilles Grelet has lived aboard his boat since 2010. He is the author of Declarer la gnose- D'une guerre qui revient la culture, Le theorisme, methode de salut public, and Citations pour le president Sarkozy (with Juan Perez Agirregoikoa), and editor of the collection Theorie-rebellion- Un ultimatum.
"""Imagine a system manual, with cryptic, occasionally humorous pronouncements among severe maxims about the life of the mind on a boat, and you have an idea of this book. What does it really mean for the mind to be at sea? How does sailing work as a genuine practice of thought […] not simply a metaphor or analogy for thought?"" —Ben Carver, European Review of Books"
