In the history of Western thought, there are not many people with great influence and widely controversial like Rousseau. He has a very famous last saying: "I dedicate my life to the truth. " This is also his motto. In the beginning, his book did not have much social impact, but only caused a lot of controversies. If it had an impact, it was limited to academia. His thoughts had a social impact since the French Revolution in 1789. It was not until the great promotion effect that the general public began to be affected. What does this text mean? ['How Rousseau struggled for his motto.', "Rousseau's thoughts are slowly tortuous in the process of being accepted by society.", 'c. "Social Contract Theory" is recognized by the people.', 'Truth always goes through twists and turns to promote social development.']
