The Infectiousness of Ideas
Where do our ideas come from ? Some, just from ourselves, or at least we believe so, but the majority come from others which we then pass on in our turn. The age-old philosophical question on the origins of ideas is analysed here in relation to their mode of dissemination. In his search for the natural element of culture, Dan Sperber presents in this book an epidemiology of ideas which describes how they spread by passing from one person to another, undergoing transformations which are in the same category as mutations. He also investigates how these ideas establish themselves in the long-term by occupying our mental world without our conscious knowledge, which allows us to participate in our culture. Dan Sperber, an anthropologist, is the research director of CNRS.
Claude Hagège
The Child who speaks two languages
At what age should we learn a second language? Which are the intellectual faculties which bilinguism helps to develop? What is the compared efficiency of language learning in childhood and in adulthood? In which case does a person forget a language, particularly a mother tongue? Claude Hagège tells us here that anybody can become perfectly bilingual and how Europe, which is not the continent where the most bilingual people are found, can multiply their number. Indeed, the challenge of bilingualism is at the heart of European union. C. Hagège, professor at the Collège de France, has published in particular L'Homme de paroles and Le Souffle de la Langue.
