Legal science can and should comply with the customary requirements as to scientificity. The fact that the doctrinal study of law is not a science has increased the popularity of the interdisciplinary approach and law-and-something disciplines. They rely on the theory arsenal of non-legal disciplines. One may ask whether there is an alternative that could make legal science stronger in the competition for scientific hegemony. The purpose of this book is to define a new legal discipline as an alternative to law-and-something disciplines and the traditional interdisciplinary approach. Its point of view is how users can use legal tools and practices to reach their objectives in different contexts. We call this new discipline User-Friendly Legal Science. User-Friendly Legal Science is a qualitative science. It is anchored in theories on scientificity, scientific theory building and scientific methods customarily used in social sciences. Its goal is interpretive understanding. It can use abduction and grounded theory. It can also be regarded as a design science that produces constructions. These concepts are common knowledge in qualitative research. The use of such tested standard parts makes it easier to develop User-Friendly Legal Science and increase its overall usability. However, User-Friendly Legal Science itself is designed as a legal discipline. The framework of User-Friendly Legal Science can help to upgrade many existing legal areas into scientific disciplines in legal research and education. Since this approach is new, a detailed account of the theory and methods of User- Friendly Legal Science might seem premature. But perhaps a book at this stage of the development of the discipline shows that there is an alternative.
