Rousseau's life connects to how we see ourselves today. 

Jean-Jacques Rousseau was a highly influential philosopher, writer, and composer from Geneva. 
His political theories often focused on the concept of legitimacy and social fairness. In his work, *The Social Contract*, he outlined how a legitimate political order might function. He also wrote the *Discourse on Inequality*, which argued that private property was a primary source of inequality. 
In the realm of literature, Rousseau helped pioneer the modern autobiography. His work *Confessions*, which he completed in 1770, focused on subjectivity and introspection. This means he wrote about his own internal feelings and personal thoughts. His unfinished work, *Reveries of the Solitary Walker*, also showed this focus. These writings exemplified the 18th-century "Age of Sensibility." This era emphasized emotional experience and personal reflection. This style of writing changed how authors approached the concept of the self.
Born on June 28, 1712, Rousseau grew up in the Republic of Geneva.
His early life was marked by significant personal loss and change. His mother, Suzanne Bernard, died of puerperal fever only nine days after his birth. Rousseau described this as the first of his misfortunes.
As a teenager, Rousseau experienced a period of wandering and religious change. At age 15, he ran away from Geneva in 1728. He eventually found shelter with a priest who introduced him to Françoise-Louise de Warens. 

In his early adulthood, Rousseau pursued various intellectual and musical interests. He spent much of his 20s studying philosophy, mathematics, and music. In 1742, he moved to Paris to present a new musical notation system to the Académie des Sciences. This system used a single line with numbers to represent intervals between notes. It also used dots and commas to indicate rhythmic values. Although he hoped this would make him wealthy, the academy found it impractical. Despite this setback, his dedication to studying complex ideas continued to grow.
