Ce volume comprend plusieurs dialogues et autres textes courts que Voltaire ecrivit en 1750 et 1751, lors de ses derniers mois en France avant son depart pour la cour de l'empereur Frederic et pendant sa premiere annee a Berlin. Dialogues, reflexions philosophiques, ecrits historiques, poesies: Voltaire ne cesse de deployer, dans tous les genres et toutes les formes, le regard critique aiguise et l'humour mordant qui sont sa marque de fabrique, et qui ont tant seduit Frederic.

Following the explosive, unauthorised publication of the "Lettres philosophiques", which revealed a new side of Voltaire to the world, a new chapter of his life began at Cirey with his lover Mme Du Chatelet. Nine years were to pass before he could again live openly in Parisian society. However, this period was among the most creative of Voltaire's life and the multifarious projects of 1734-1735 show an author attacked and exiled but nevertheless able to turn his hand to an astounding range of projects. This volume includes texts as diverse as "Alzire", a tragedy set in sixteenth-century Peru, contrasting the noblest ideals of Christianity to both Incan religion and the dangerous fanaticism of the Conquistadors, the monumental "Traite de metaphysique", and some of Voltaire's first love poems to the marquise Du Chatelet.

1739-1741 were stressful but highly creative years for Voltaire, his output ranging from science to polemic, from politics to poetry. Scientific research remains at the forefront, with Voltaire championing Newton's theories despite the opposition of the scientific establishment. Voltaire was in this period anxious to consolidate his reputation, and his continuing reflections on the nature of a literary career led to the publication of both his personalised "Memoire du sieur de Voltaire" and more general reflections on literary quarrels in "Memoire sur le satire". Public quarrels had become an integral part of the 'Republic of Letters' and Voltaire's disillusionment is clear in "Lettres sur les inconvenients attaches a la litterature". His verse ranges from crude satire to some of his most touching lyric poetry in the "Stances a Madame Du Chatelet". Altogether, this collection brings together the complex and contrasting works of a complex and flexible writer.
