“…Ce livre offre une réflexion dynamique et transversale sur les multiples facettes culturelles de cette relation paradoxale qui lie le jeu et la guerre moderne : de Naudé concevant le peuple comme un pion manipulé par un souverain démiurge, aux analogies médiatiques entre musique et guerre dans le documentaire filmique Heavy Metal in Baghdad, en passant par Schlieffen élaborant sa stratégie dans des Kriegsspiele militaires, ou encore par le Jeu de la Guerre de Debord et son adaptation « situationniste » en wargame informatique. …”

“…A former communist prison island in the Adriatic Sea, now abandoned and overgrown with wild plants; the stone garden of a deaf Iranian peasant who dances ecstatically among his geological formations; a Belgian sculptor who combines wax and flesh to depict human and animal forms in states of half-manifestation, incompletion (missing limbs), or branching (morphing into other organisms); a cultural movement in Brazil that takes the discarded debris of urban centers and transforms their splintered wood pieces into massive labyrinths and underground caverns; a blacksmith poet in Afghanistan who alternates between tasks of hammering metal and writing lyrical verses amidst the smoke-clouds of his forge; a Cuban writer whose delirious fixation with the sea compels him to invent a language of pure untimeliness. …”
