In 1999, Time magazine named “The Other America” one of the 10 most influential nonfiction books of the 20th century. But how relevant does it remain today? As social theory, it is deeply flawed. Harrington’s culture-of-poverty thesis was at best ambiguous, at worst an impediment to making the case for what he regarded as the real solution. (In later books, he made no use of the term.)'Moral clarity' is a euphemism for a strongly held belief in right and wrong, usually used by those who agree with the dichotomy. 'Manichean', 'platonic', 'naive', 'simplistic', 'absolutist', are common criticisms of these views, and usually by the left towards the right.
But what remains fresh and vital in “The Other America” is its moral clarity.
'Moral clarity' is one of those virtues that is ambiguous by itself, because allied with a misguide notion it is the basis for a great amount of evil. Strong moral feelings without a good discrimination mechanism, is like having a powerful gun with no aim (Mr. Evil himself, Adolf Hitler, had large amounts of it). As Oscar Wilde has noted, many people die for sincere beliefs that are rather absurd. When the most singular compliment one can say about a former intellectual pertains to their 'moral clarity', you can be sure they are irrelevant to current debates, relevant only to biographers and historians.
