Legal experts convey with a serious demeanor who has rights and obligations. They make us believe that they actually know this. Legal theory delves into the question of whether this claim to knowledge can be taken seriously. It is no coincidence that it emerges as a discipline from the upheaval of the intellectual self-confidence of established legal science. This upheaval began at the turn of the nineteenth to the twentieth century and continues to this day. Alexander Somek's volume offers a selective and pointed introduction to prominent legal theoretical positions such as American legal realism, modern legal positivism, systems theory, institutionalism, critical legal studies, and social choice theory.
