Legal Positivism and Conceptual Analysis Positivismo juridico y analisis conceptual The recent discussion about legal positivism is whether or not a iuspositivist conception can explain two characteristics of contemporary legal systems that seems indisputable: that the existence of law is practice-dependent and that moral reasoning forms part of the processes of identification and application of contemporary legal systems. Those characteristics can be referred to as thesis of the social sources of law and the thesis of incorporationism. The first part of this book centers on the question on the debate between exclusive and inclusive legal positivism and the moral argumentation of constitutional law.
