Answer 1

titled "Emile, or On Education" was published in 1762. This groundbreaking work explored Rousseau's ideas on natural education and the importance of nurturing a child's own innate abilities and inclinations. It had a significant impact on the field of education and child development, influencing many subsequent thinkers and educators. Rousseau’s emphasis on allowing children to learn through exploration and experience rather than strict academic instruction was particularly revolutionary at the time.
