I've said before that I don't want this blog to become a YouTube showcase, but I find so much really neat stuff there. This clip is from the 1973 TV series The Ascent of Man. Hosted by Jacob Bronowski, the series was designed to promote science (in a manner similar to Carl Sagan's Cosmos series). Here Bronowski is defending the idea of scientific knowledge as opposed to doctrine and dogma. He does so from the grounds of the Auschwitz concentration camp where members of his own family perished during the Holocaust. His argument is both eloquent and timeless and the presentation riveting.
