1789 The bourgeois revolution that broke out in France opened a new era for the development of capitalism in Europe, and the democratic movement and national liberation struggle began to rise. This period not only produced Kant (1724- 1804), Fichte (1762- 18 14) and Hegel (1770-/kloc). But also produced the Saint-Simon (1760- 1852), Fourier (1772- 1837), Irving (177/kloc-0). Their philosophical and sociological thoughts are closely related to the development of western literature and art in this period. Advocating humanism and individualism, advocating freedom, equality and fraternity are the ideological core of romantic literature and art.
