On this day 313 years ago, June 28, 1712 (May 25, 1712 lunar calendar), the birthday of Rousseau, "the father of the French Revolution". Rousseau, 18th century French Enlightenment philosopher and socio-political thinker. Born on June 28, 1712 in Geneva, Switzerland, he spent most of his time in France, and died of illness in Ermnonville near Paris in 1778. The main theoretical works are "On whether the progress of science and art helps to transform the vulgar", "On the Origin and Foundation of Human Inequality", "On the Social Contract", "Emile" and his autobiography "Confessions". The basis point of Rousseau's thought was the opposition between "nature" and "civilization", which he used to criticize Christianity and feudal socio-political systems. He believed that in the prehistoric state of nature, man was kind, free, equal, and compassionate. Since the development of productive forces led to the emergence of private property, people ended the state of nature and entered into a civilized society by establishing states and laws to guarantee freedom and equality, property, and person through social contracts. But all subsequent social and political developments have left man increasingly oppressed, enslaved, and trapped in a state of moral decay. The feudal autocracy was the culmination of this development. The people used violent revolution to overthrow it and established a bourgeois democratic republic of popular sovereignty, rule of the general will, and rule of law on the basis of a new social contract. These ideas had a significant impact on the French Revolution of 1789, the bourgeois revolutions in Europe and America, and their socio-political ideas.
