This creative course gave me the opportunity to think again about some basic concepts which are vital for diplomacy, such as: the relevance of framing an argument; language as action; construction of a narrative, and the power of persuasion. Moreover, we had fruitful interactive sessions where we discussed thought-provoking questions, among others: Should diplomacy be judged by its management of ambiguities or for its capacity to deliver results? How can we deal with, and understand, the multiple possible meanings of the unsaid?
