Koinoniología tou Dikaíou (Sociology of Law) by Thanassis Papachrístos is a handbook with an agile, unconventional structure: ideas and critical propositions follow a particularly free logical concatenation. Sociology of law is not only a sci-ence, but also a dynamic, reactive mental attitude: it creates more aware legal op-eratives who are better prepared to interpret complexity. One theme central to the author’s thinking is that of the legal neo-pluralism of the current day. Globalisa-tion does not always mean uniformity; on the contrary, it sometimes conceals an even more complex legal stratification. Even within individual countries, a new form of pluralism is emerging. The law of the state fulfils the function of conduc-tor of the orchestra of legal orders of various different kinds. The need to restrict state law in favour of other normative systems is expressed in the name of deregu-lation (cf. the theorists of neo-Liberalism). All this takes place without ceasing to use the tool of codification.
