Let us close this week with the work of photojournalist James Nachtwey, whose images testify not only to the terrors of greed and war, but to a man's dedication to the truth. Like any artist worthy of the title, Nachtwey teaches us--through a medium that competes with the white noise of (mis)information, deceit, and the repetitive strain of everyday living--to look a bit closer at the world, to investigate and question all that we presume to know.

Have a good weekend, everyone. [DR]
