Through the historical-comparative method, the course aims, in the first part, to provide students with the tools to analyze and understand different concepts of law and different ways to legitimate the law in the main legal traditions (Civil law, Common law, legal systems of Islamic countries, main Asian legal systems, South American legal systems). In the second part, the course aims to let the students experiment with ways to solve practical legal problems (in the field of property, contracts and civil liability) in the framework of different legal systems that are representatives of different concepts of law.
