Humans massively depend on communication with others, but this leaves them open to the risk of being accidentally or intentionally misinformed. To ensure that, despite this risk, communication remains advantageous, humans have, we claim, a suite of cognitive mechanisms for epistemic vigilance. Here we outline this claim and consider some of the ways in which epistemic vigilance works in mental and social life by surveying issues, research and theories in different domains of philosophy, linguistics, cognitive psychology and the social sciences.

Geoffrey Leech stresses the contribution of semantics to the understanding of practical problems of communication and concept-manipulation in modern society.

This work represents Niklas Luhmann's definitive application of systems theory to the understanding of law. In it Luhmann reviews past attempts to create a theory of law and argues they all fail to capture how law operates in modern society. He presents an alternative, critical theory through analysing law as a system of communication.

In this volume, Niklas Luhmann, the leading exponent of systems theory, explores its implications for our understanding of law. The volume provides a rigorous application to law of a theory that offers profound insights into the relationships between law and other aspects of contemporary society, including politics, the economy, the media, education, and religion.Readership: Academics and students of sociology, law, philosophy, and legal philosophy.
