The book offers a profound understanding of how we create a social reality—a reality of money, property, governments, marriages, stock markets and cocktail parties. The paradox addressed is that these facts only exist because we think they exist and yet they have an objective existence. Continuing a line of investigation begun in his earlier book The Construction of Social Reality, the author identifies the precise role of language in the creation of all “institutional facts.” His aim is to show how mind, language and civilization are natural products of the basic facts of the physical world described by physics, chemistry and biology. The author explains how a single linguistic operation, repeated over and over, is used to create and maintain the elaborate structures of human social institutions. These institutions serve to create and distribute power relations that are pervasive and often invisible. These power relations motivate human actions in a way that provides the glue that holds human civilization together. The author then applies the account to show how it relates to human rationality, the freedom of the will, the nature of political power and the existence of universal human rights. In the course of his explication, he asks whether robots can have institutions, why the threat of force so often lies behind institutions, and he denies that there can be such a thing as a “state of nature” for language-using human beings.
