This chapter deepens the insight that tort law fulfils a societal role. It locates the classical model of tort liability, namely individual responsibility, within a wider privatist societal constitution. Both contract and tort, however, are understood as second order observations of the knowledge base of society, which has broken free of tradition and centralized authority in modernity. Therefore, private law models its dynamic knowledge base, and provide a constitution of civil society that unleashes experimentation and enables a 'relational rationality' to unfold. The gradual emergence classical tort law is documented, and its constitutional role underscored through examples from of private and public liability in English, French and German law. The society of individuals on which the law of torts is modelled, however, begins to rupture by the end of the 19th century, and it becomes increasingly difficult to frame all legal problems as issues of corrective justice. Nonetheless, the legacy of classical tort law, is a model of individual responsibility, which continues to shape scholarly engagement with tort law, and continues to impact on how legal problems are perceived in law.
