The biggest questions are human questions

Covering the presentations at this year's TED, Ethan Zuckerman has wrapped up his marathon liveblogging effort with posts that drive home the point that the Big Questions that were theme of TED08 have all-too-human dimensions.

One post points out the lack of political diversity at TED and describes why people of all political persuasions need humility.

Using the famous Zimbardo experiments and, more recently, the torture of prisoners at Abu Ghraib, another post describes the latent capacity of everyone to engage in behavior that under normal circumstances we wouldn't even contemplate. Why, indeed, do ordinary people do evil things?

And lastly, read Ethan's post about why John Francis didn't speak for 17 years. What did he - what can we - learn by not talking?
