These essays in honour of Ad Borsboom focus on a theme that is central to his long career (from 1972 onwards) in the service of Pacific Studies in the Netherlands, and in particular of Aboriginal Studies: the transmission of knowledge. As a prominent ‘life long fieldworker’, Ad has always been engaged in this subject, which he approached from different angles. First, like every anthropologist while doing fieldwork, he was interested in learning from his hosts – not merely by acquiring ‘data’, but first and foremost by ‘learning lessons’. These lessons, which left a profound impression on him, confronted him in most fundamental ways with his own, ‘western’ epistemology and worldview. It motivated Ad later to share his insights and experiences with colleagues and students, and in particular with ‘the general public’: he became a tireless advocate for the world he had so intimately familiarised himself with: in television and radio broadcasts, in newspapers, for visitors of museums, such as the Aboriginal Art Museum, and in extra-academic courses he tried to transfer his insights. Deserving a special mention is his ‘long seller’ De clan van de Wilde Honing (‘The Sugarbag Clan’). He even cooperated in an exhibition project for the Tropical Museum Junior in Amsterdam in 1995. In this award-winning exhibition, Verhalen om niet te verdwalen (‘Stories so as not to get lost’), at the children's museum, and in the accompanying educational materials, Ad again shared many of the insights he had gained in Arnhem Land, Australia, over the years. What is more, he thoroughly discussed the exhibition with the Djinang – the Aboriginal people he worked with – and commissioned them to create artefacts and art works especially for the event. The successful show included performances and special effects. Moreover, it presented visitors with a view of the present-day way of life of the Djinang, using modern means of communication and transportation. The transfer of knowledge was the underlying concept of the exhibition in more than one way: children (between the ages of six and twelve) were first invited to experience the exhibition on their own. Thereafter, they were given the opportunity to show their parents or caretakers around, thus transmitting to the adults the knowledge they had acquired during their first visit.
