These days, a century after the famous Paris convention on comparative law, comparative legal research is booming. A large percentage of legal research – at least in the Netherlands – currently is conducted on a comparative basis. However, whereas the interest in conducting comparative legal research is growing, the interest i n how to carry out this type of research is diminishing. Applied comparative legal research is supposed to be ‘good’; discussions on how to carry out this type of research are considered a waste of time. I would agree wholeheartedly with the latter statement if there were a clear, crystallized and accepted theory, or if there were no need for a method at all. In my opinion, the latter statement thus must be rejected. Although, as is often said, ‘a lot’ has been written about the methods of comparative law, there is still no consensus on a theory of comparative law. Ideas on methodology are elaborated from different points of view and no unequivocal concepts are used. The idea that there is no need for a method denies both the academic character of comparative legal research and the fact that nowadays a great deal of comparative legal research is carried out by relatively young and – in the field of comparative legal research – inexperienced PhD students who would welcome some clear guidelines. As methods are simply lessons learned by people who have done something by trial and error, why shouldn’t one benefit from the lessons learned by others?
