What is the core of legal scholarship? How can we understand its relation to other disciplines, such as moral and political philosophy, sociology, and economics? I explore these questions by analysing the impact of the dual nature thesis. Criticising established theories of legal scholarship, I defend the ideal of an integrative jurisprudence. Integrative jurisprudence combines the two dimensions of law by employing analytical, empirical, and normative methods. I then discuss three objections and address the problem of how to bridge is (...) and ought. In the course of my analysis of three different bridge theories, I ultimately further develop the dual nature thesis into a triadic nature thesis. (shrink)
