Yesterday and this morning, I sat at the plenary sessions and listened to those often remarkably intelligent people talking to around 600 probably very clever attendants about intercultural dialogue. How can it be promoted, what are the obstacles getting in its way, what are the tools involved and what is their impact etc.? And I came to think about the very concept of dialogue. Its definition on the most used Internet sites seems to involve “two or more people” and a “conversation”, this last concept involving “communication” and “two or more people” (by the way, the definition of “conversation” on Wikipedia is quite surprising and interesting…). So basically we are left with “communication” and “two or more people”.
