Zeitgeist is a concept that, translated from the German, means "spirit of an era"--the intellectual, moral, cultural climate of any given moment in time. We live in a world today that is fraught and increasingly complex. Have we lost our grasp on this world or can we still shape it? Who or what is shaping world? How will we define ourselves, as individuals and as a society? What is the zeitgeist of our day? Student and guest speakers will broach these questions as they examine the state of the world today in science, humanities, technology and the arts at this year's TEDxPineCrestSchool.
