French and Industrial revolution, two most important social transformations that not just changed the outlook of the world. They also changed the way how people think, feel, and believe in the new society. In Edmund Burke’s Reflections on the Revolution in France (1790), Burke showed how French Revolution  formed social instability by threw away old traditions like the spirit of gentlemen and the spirit of religion. He also argued that what France need is reform not revolution, he demanded for Monarchic system to come back. In contrast, in Percy Bysshe Shelley’s A Defense of Poetry (1821) he advocated French revolution’s idea of Enlightenment. He believed that people with awareness of nature and rational thinking can work together to address problems in society. While Burke and Shelley both disagree on effects of French revolution on society, they both agree on that the importance of tradition, nature, freedom and etc. They both believe that rational thinking can not success without emotional, desire part of human. However, whereas Burke emphasizes on conservative perspective, he believes that French revolution is unnecessary, Shelley demonstrates that Revolution ideas/thinking (Poetry) can construct a better society and bring back things lost from past.
