Watch these two lectures on justice. Sandel attacks the abstract approach of Rawlsian constructivism. He emphasizes the undesirability, if not the impossibility, of arriving at principles of justice from an unencumbered self-devoid of attachments to community and a comprehensive doctrine encompassing what it means to live a good life. Sandel does not see humans as individuals that choose a particular form of life or that can abstract themselves from a particular form of life or comprehensive doctrine. Rather, communities and comprehensive doctrines are constitutive of individuals.
