Take the US. Women were not even able to vote until 90 ago, at about the same time they gained the right in Afghanistan. Rights of former slaves were very limited until the 1960s, and in some ways still are. In these and other domains there has been progress in democracy, though still seriously flawed. In other dimensions - the control of concentrated wealth over the political process, for example, things have gotten much worse in recent years. And there is much more, in both directions.

I don't suggest that the observations are surprising or profound. Rather, they seem to me the merest truisms. I was not aware that [ Michel] Foucault had used the phrase "speaking truth to power." I had thought it was an old Quaker phrase.

We are entering a period of human history that may provide an answer to the question of whether it is better to be smart than stupid.

When I arrived in Laos and found young Americans living there, out of free choice, I was surprised. After only a week, I began to have a sense of the appeal of the country and its people - along with despair about its future.

My suspicion is that those who seem oblivious to suffering, whether it is nearby or in remote corners, are for the most part unaware, perhaps blinded by doctrine and ideology. For them, the answer is to develop a critical attitude toward articles of faith, secular or religious; to encourage their capacity to question, to explore, to view the world from the standpoint of others. And direct exposure is never very far away, wherever we live - perhaps the homeless person huddling in the cold or asking for a few pennies for food, or all too many more.

A 1998 study was done in Hebrew by an Israeli scholar, Yosef Grodzinsky, and the English translation of the title is Good Human Material. That's what they wanted sent to Palestine for colonization and for the eventual conflict that took place some years later. These policies were somewhat complementary to the U.S. policy of pressuring England to allow Jews to go to Palestine, but not allowing them here. The British politician Ernest Bevin was quite bitter about it, asking, "if you want to save the Jews, why send them to Palestine when you don't admit them?"

If you don't like what someone has to say, argue with them.
