The origin of civil law is the basic system in legislation and theories of this law, which is of great importance for legislators to make law scientifically, of great importance for legalists to foresee the result of behavior accurately, and of great importance for judicators to choose law correctly. However, the legislation and theories of civil law in our country haven’t been paying much attention to this system during a long time. The arbitrary legislation hasn’t been providing a discussion platform for academic criticism. What’s more, it has been also bringing lots of negative influence to civil activity and justice, all of which made the legalists and judicators don’t know how to deal with in some areas. In the theory, though scholars treat the origin of civil law as an important part in this law, most of them have been only focusing on this system in the foreign countries. They haven’t discussed and critiqued the origin of civil law in current law of our country, and even haven’t deeply investigated every kinds of civil law’s origin and their manifestation. As far as the methodology, the scholars haven’t been discussing the legal practice either, and even haven’t been using legal philosophy and integral method. Besides that, though lots of them have used a large number of comparison methods, they haven’t been using them abundantly. In this context, this paper try to stand on the point of legal philosophy, use integral and comparison method, and then discuss the viewpoints which comes from different scholars and the origin of civil law system in our current legal legislation. The paper is divided into three parts. Accordingly, the first part is general discussion (from first to sixth section). This part comments and analysis the origin of civil law and the origin of law; and the origin of civil law and that of Public law; what’s more, it also introduces the origin of civil law in other countries and districts, and the scholars’ different expressions of civil law’s origin; besides that, it gives us the regulation of the civil law’s origin in the legal legislation in our country. Because of the various meanings of “law’s origin”, this essay firstly divides the law’s origin into some parts. These parts include the origin of law’s content, the origin of law’s restraint, and the expression of law. Besides that, the paper also use the integral method to bring the origin of civil law into the relationship between civil law’s origin and the origin of civil law’s contents and restraint to analysis this system. In the consideration of different principles of the private law and the public law, this essay stands on the point of department law to compare the origin of these two kinds of law. Besides that, it also uses comparison method to comment the advantages and disadvantages of the origin of civil law in different civil law countries, and then sums up two kinds of legislation framework, which is concrete framework and concrete-abstract framework. By analyzing the scholars’ different expressions of the origin of civil law, and the regulations of the civil law’s origin in the legislation of our country, the paper point out some problems which is worthy of discussion, and which is also preparing for the second part at the same time. The second part is the concrete discussion (from the seventh to ninth section). It deeply investigates the suitability and existence form of every kinds of civil law’s origin. These kinds of origin include enacted law, customary law, legal principal, treaty, case, policy, and group agreement, and so on. The last part is conclusion (the tenth section).
