A European Legal Method? On European Private Law and Scientific Method

This article examines the relationship between European private law and scientific method. It argues that a European legal method is a good idea. Not primarily because it will make European private law scholarship look more scientific, but because a debate on the method of a normative science necessarily has to be a debate on its normative assumptions. In other words, a debate on a European legal method will have much in common with the much desired debate on social justice in European law. Moreover, it submits that, at least after the adoption of the Common Frame of Reference by the European institutions, European contract law can be regarded as a developing multi-level system that can be studied from the inside. Finally, it concludes that the Europeanisation of private law is gradually blurring the dividing line between the internal and external perspectives, with their respective appropriate methods, in two mutually reinforcing ways. First, in the developing multi-level system it is unclear where the external borders of the system lie, in particular the borders between Community law and national law. Second, because of the less formal legal culture the (formerly) external perspectives, such as the economic perspective, have easier access and play an increasing role as policy considerations.
