More poignant, though, are the areas of concurrence, especially the central theme that matters of race permeate the lives of African Americans, even those as successful as these two men. Griffith skillfully discusses Pierce's application of research findings about the human response to extreme environments (at the South Pole) to the exigencies of black life in America. At least among African Americans, some of Pierce's terms and concepts—micro-aggression, micro-traumata, and racism as an environmental pollutant—are abiding.
