When all the people of the world nally speak the same language and commune in the same message or the same norm of reason, we will descend, idiot imbeciles, lower than rats, more stupidly than lizards. The same maniacal language and science, the same repetitions of the same in all latitudes-an earth covered with screeching parrots. (Serres, 1997, p. 124) The goal of instruction is the end of instruction, that is to say invention. Invention is the only true intellectual act, the only act of intelligence. The rest? Copying, cheating, reproduction, laziness, convention, battle, sleep. Only discovery awakens. Only invention proves that one truly thinks what one thinks, whatever that may be. (Serres, 1997, pp. 92-93) Once more, the gure of the Troubadour appears in front of me, classically elegant, passionate, a stunning portrait of craftsmanship in story-telling. He is a poet-musician who travels through medieval Provence and sings about love. 1 The love of learning and knowing, the love of nding and invention. I wonder about the marvellous places he has been and the majestic expeditions in which he took part. His telling of his adventures is masterful and fascinating, often improbable, painted with elegant language and clarity. Story after story and song after song are energised by the Troubadour's poetic imagination that animates his stories with vivid images, long forgotten by the rest of us. Intricate in their interweaving of past and present events, the Troubadour's stories come across with a full measure of the complex vision of the world of knowledge.The above scene is very real except that it does not take place in medieval France any more. All the rest describe the gure of one contemporary French 'Troubadour of knowledge' who travels across traditional boundaries of space and time and teaches us about the love of wisdom (philo-sophy) and invention. He is Michel Serres, a provocative and unorthodox thinker, very little known in the Englishspeaking world, although he is one of the best-known contemporary French philosophers. Serres' interdisciplinary writing constructs themes that can be traced across literature, philosophy, science, mythology and painting, borrowing ideas and approaches from them and transforming those into original and synthetic voices in the world of knowledge. By grounding the sciences into everyday life, Serres wants to eliminate the distance that is perceived to exist between the two. His writing style is beautiful, poetic, evocative yet demanding and dif cult. This dif culty is partly
