Abstract:
When the National Science Foundation announced two grants late last month to ponder nanotech's impact on society, I turned to Chris MacDonald for some 5-cent philosophical help. Chris is a philosopher and ethicist at Saint Mary's University in Halifax, Nova Scotia, where I suppose a great deal of time spent trudging through the tundra would turn anyone's contemplations to the ultimate good or evil inherent in tiny particles that have the potential to self-assemble into a giant mess.
