Played hero often but still too quiet!?: Prof. Dr. Gunter Dueck at TEDxKoeln

As Lichtenberg says: "It is virtually impossible to carry the torch of truth through a crowd, without singing someone's beard."
What is the point of destructing truth if it's supposed to be enlightening instead? Don't I have to be worried about my own beard or skin even? Do I have to arm myself for the truth and play with fire? Am I going to be dismissed as an omega-animal? Or shall I disarm the others as kids and fools would do?

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)
