Traditional legal theory and sociology of law have responded to the ontological question of"what is law"by adopting a reductionist framework,which makes it difficult to adequately account for the increas-ingly complex phenomenon of legal practice.An irreductionist ontology of law would hold a morphogenetic view of law as a network of heterogeneous entities whose distinctive feature is a holistic network feature that emerges within it.In this morphogenetic view,the heterogeneous entities in the network of legal prac-tices are referred to as"jurimorphs,"which,on the one hand,have different individual properties of their own and,on the other hand,have legal means to the totality of law.The discovery of legal means requires that the human participants in the practice of law be imbued with the intrinsic subjectivity asked by legal practice.The distinctive feature of the network of legal practices is that it provides a unique form of mobili-sation,makes specific acts of practice assignable to their subjects in a superficial and formal way.An irre-ductionist ontology of law complements the existing conceptual and empirical approaches to legal ontology,and is able to provide a more adequate account of the growing phenomenon of technology in legal practice.
