Explore the natural world through Jean-Jacques Rousseau’s letters on botany—a beautifully written reflection on plants, nature, and philosophy by one of the Enlightenment’s greatest thinkers. Whether on his philosophical walks or his bucolic wanderings: Jean-Jacques Rousseau, a Swiss-born philosopher, writer, and composer whose works profoundly influenced the Enlightenment and the French Revolution, always portrayed a deep passion for plant collecting. Between 1771 and 1774, he composed eight letters offering lessons in botany, addressed to Madame Delessert and destined to teach her young daughter Madelon. These letters constitute the thinker’s final work, alongside Reveries of a Solitary Walker, and reverberated throughout Europe in the early nineteenth century. Rousseau’s project was much more than a simple lesson in pedagogy; it is, rather, a genuine invitation to observe plants. Under his pen, the descriptions are elevated to the rank of art, and contemplation achieves the status of science. Liliaceous, cruciform, papilionaceous, and umbellate plants combine to compose a poetic herbarium.
