The article about Camus in the April 9 issue of the New Yorker (which is unfortunately only online for subscribers) contains this quotation from Camus:
We have witnessed lying, humiliation, killing, deportation, and torture, and in each instance it was impossible to persuade the people who were doing these things not to do them, because they were sure of themselves, and because there is no way of persuading an abstraction.
How does one talk to those who are so sure of themselves that they never doubt the validity of their actions, no matter what the content of those actions may be? If you perceive someone as being so full of certainty and completely unwilling/unable to be skeptical about their own beliefs, then perhaps the only thing to do is not to talk to them, but to talk to others who are not as uncertain, to help them avoid being persuaded by abstract certainties that lead to "lying, humiliation, killing, deportation, and torture."
Still, it would be nice if the people in power were not engaged in those activities quite so unreservedly.
Near the end of the article, Adam Gopnik paraphrases Camus's position on place as follows: No human being is more indigenous to a place than any other. This rootless cosmopolitan applauds such a point, but Camus's basis for it is quite convincing: his mother may have been a French colonist in Algeria, but she worked as a cleaning lady; she had none of the privileges of the colonial. And Camus, born and raised in Algeria, was as Algerian as anyone else born and raised there.
