This documentary is an unusually fine example of what philosophy can do when it's done properly. Stephen Hicks takes the viewer on a information rich tour of the intellectual history of 20th Century Germany. His presentation is scholarly, fastidious, and fair.
Hicks refuses to completely acquit Nietzsche of responsibility for Nazism, but he doesn't stoop to cheap caricatures, either. Nietzsche, no pale criminal, would likely accept responsibility for everything Hicks levels at him. After all, to call Nietzsche "dangerous" is merely to appreciate him in full.
But Hicks is not merely doing positive intellectual history. This video essay is also a normative philosophical endeavor. Hicks takes the unfashionable view that ideas have consequences, that they drive history. Hicks appreciates that Nazism was a highly sophisticated and fully-articulated philosophy. As Walter put it The Big Lebowski, "Say what you want about National Socialism dude - it's an ethos." Nazism was not a spasm of madness, but a coherent response to perennial questions. It is not enough that we dismiss Nazism, or simply forget it; in the long run it's certain to emerge once again. Instead, Hick holds, we have to engage it - and engage Nietzsche - to determine and then to prove where each goes wrong and why.
Hicks sees philosophy as a sort of ideological bomb squad, dispatched to dismantle rogue ideologies before they become catastrophes. As thrilling as I find this notion, my view is a bit more cynical. In 1930's Germany, Hicks has identified one of the few points in the last 2000 years when philosophy had some causal traction on the highway of world history - and in that instance the result was not pretty.
Still, if you're interested in these things you'll be hard-pressed to find a more engaging three hours of television anywhere.
