The Oxford University Studies in the Enlightenment series, previously known as SVEC (Studies on Voltaire and the Eighteenth Century), has published over 500 peer-reviewed scholarly volumes since 1955 as part of the Voltaire Foundation at the University of Oxford. International in focus, Oxford University Studies in the Enlightenment volumes cover wide-ranging aspects of the eighteenth century and the Enlightenment, from gender studies to political theory, and from economics to visual arts and music, and are published in English or French.

"I am now alone on earth, no longer having any brother, neighbor, friend, or society other than myself" proclaimed Rousseau in Reveries of the Solitary Walker. Reveries, along with Botanical Writings and Letter to Franquieres, were all written at the end of his life, a period when Rousseau renounced his occupation as author and ceased publishing his works. Presenting himself as an unwilling societal outcast, he nonetheless crafted each with a sharp eye on his readership. Whether addressing himself, a mother hoping to interest her child in botany, or a confused young nobleman, his dialogue reflects the needs of his interlocutor and of future readers.
Although very different in style, these three works concern overlapping subjects. Their unity comes from the relation of the other writings to the Reveries, which consists of ten meditative "walks" during which Rousseau considers his life and thought. The third and fourth walks discuss truth, morality, and religious belief, which are the themes of the Letter to Franquieres; while the seventh is a lengthy discussion of botany as a model for contemplative activity. The overarching themes of the volume--the relations among philosophic or scientific contemplation, religion, and morality--provide Rousseau's most intimate and final reflections on the difficulties involved in understanding nature.
