The landscape of what is here called "the new knowledge age" includes radical developments in the following areas: information and communication technology, the rethinking of the sciences and scientific work, the new emphasis on the ecology of the information phenomenon, and the re-articulation of what it means to be human in this new age of the electronic media. The drastic and dynamic changes related to these developments confront knowledge workers, also working in the area of knowledge organisation (KO), with dramatic new challenges. Therefore the focus of this article will be on human persons and their qualities as the decisive, key aspect of KO. For humans to adapt and respond in significant ways to these challenges pertaining to a variety of activities in our field, require the development or re-development of certain specific, uniquely human, qualities. The breakdown of disciplinary boundaries demand the ability to act between the disciplines (the instructed third), to navigate all the dimensions of the knowledge networks, to willingly become an eternal learner, to read more and differently from the usual ways, to display an uncompromised commitment to thinking in a new key, and to continuously participate in an infinite conversation. These are the required qualities for the new dispensation, and can only materialise when the much neglected imaginative noetic (spiritual) capacity all humans possess are wholeheartedly embraced and also cultivated. Together these well-developed qualities should have only one outcome: inventiveness - the invention of new and appropriate knowledges for special needs and actions in societies. The name selected for such a qualified knowledge worker or information professional is "the troubadour of knowledge".
