Query: What they say about Emerson

For biography, try Robert Richardson's "The Mind on Fire." If you wish to know more about the literary dance that goes on in the minds of authors, philosophers, theologians, and psychologists about Ralph Waldo Emerson, this is the book..His popularity has fluctuated since his death in 1882, but unless someone can inform this reviewer otherwise, Emerson is still the most quoted of all American authors..Since he was born in 1803 (May 25th), this is the year of his bicentennial..The book informs us that he reached the peak of admiration around the time of his centennial, 100 years ago.After that,it diminished quite a lot,and these days he may be making a comeback..The last word in the last chapter tells us that Emerson "inspires." And a previous chapter tells us that he was concerned with "values that stand the test of time and unite the world."
