This article deals with a basic concept informing the work of Elliott Jaques: trust which is the social glue that binds people together and has consequences for all social domains. The etymological origins of “trust” connect with major normative concepts, including truth and relying upon others. These are vitally connected with the psychoanalytic approaches of Sigmund Freud and Melanie Klein as well as the nature of requisite and anti-requisite practices throughout society.
