Necessity. Possibility. Effectivity. These are the three modalities, or modes, that according to philosopher Jordi Claramonte, in their different ways of realting with each other, can help us better understand life, change and the options we have. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
