Abstract: Studies on English social theories tend to emphasize utilitarianism as their main trait, ignoring the diverse and complicated change and fusion in history. After experiencing wars and revolutions, England was obliged to search for new ideas and ways in response to the new social reality without abandoning its intellectual tradition.  In the early 18th century, the infusion of Scottish enlightenment dramatically changed the political society of English Puritan tradition and introduced something new based on the emerging civil commercial society.  Locke’s ideas of natural law and freedom constitution are within the paradigm of Christianity. His Puritan tradition planted seeds for future radicalism. Hume’s “science of man” revealed the common course of things and presented political science as a product of philosophical reasoning upon historical facts. This is an important turning point in English history of political thoughts. From classics to human history, Hume gave us a solid foundation of philosophical reasoning and opened up a new way of social and political studies：a new liberal tradition in English political thoughts. This paper tries to map out these changes in England political thoughts from Locke to Hume by a close examination of the two important Philosophers’ ideas. Lessons can be learnt from this study as China is currently experiencing a transition much similar to the one England had experienced.
