What happens when three historians encounter a mysterious historical source? This episode is the fourth installment in the series, "Three Professors and a Primary Source." This episode, "Analysis," demonstrates how historians use the knowledge gained by answering the first six interrogatories posed in the first three episodes. By the process of analysis, the historians use the facts (or elements) gained from the source and apply those facts to a higher level of thinking. Analysis is the process of examining all of the elements of the source and interpreting meaning from them. Those meanings may be personal, political, psychological and/or cultural, and historians do not always agree on each point. Most important, the process of analysis allows the historians to use a source in order to better understand the most complex issues besetting our past and present day. Here, three history professors engage in an analytical discussion about Robert Penn Warren, author of "New Dawn," a poem that appeared in the 1983 edition of John Hersey's famous text, HIROSHIMA. Thanks to Dr. Richard Hernandez, Dr. Gerry Prokopowicz, and Dr. Chad Ross for their participation in this exercise.
