Abstract
Rousseau? Centuries of biobibliographic investigation, philosophical speculations, and musical rehabilitation, but more discreet technical studies on the dominant of a work, the lexicon, the sentence, the images or this and that process. Rousseau: a tercentenary event, scientific and popular, in 2012, and still being published, the scholarly edition of his complete works in twenty volumes. Rousseau then! Transparency and the obstacle..., and an investigation as close as possible to his writing as a novelist, essayist and autobiographer.
