Decidedly, Sylvain Tesson has a beautiful stroke of the pen. It covers the world a piercing glance and knows better than anyone briefly describe a landscape, an emotion, an idea. He has the art of the formula he handles maybe sometimes to excess, but can you blame him? Volunteer, adventurous, excessive, Sylvian Tesson travels the world and shares his visions, his feelings, his indignation, his passions. It tracks the absurd, the paradox, the incongruous; as well as beauty. Never sentimentality or sagging home. Collected texts written between 2006 and 2012, found in "Geography of the moment" environmentalists tickets, socio-political criticism, mystical reflections, and above all, and this is the most gratifying, articles on literature and writers. Hollow appears the portrait of a man demanding and daring and a world in motion, change. A world under strain, when man colonizes and destroys all spaces shamelessly. "Forests precede men, deserts succeed them." warns Sylvain Tesson citing Chateaubriand. A book that is eaten, that makes you want to travel, to read and write; which "invites to conquer the essentials."
