It never ceases to amaze me that critics insist that the Book of Mormon read like a doctoral dissertation with an extensive introduction and massive references explaining all of the details relative to the culture and environment in which the history takes place.
Brant Gardner explains something about this in his introductory chapter to volume one of “Second Witness” He references Bible scholars who point out that our modern culture is what is called a “low context environment” culture. This means that we expect the writer to explain every detail of the environment in which the story takes place. An example is the need for an extensive introduction to a doctoral dissertation with massive amounts of references and extensive explanations of what has already been done in the field. The Bible and other ancient writings, however, are written in what is classified as a “High context” environment. In this environment the reader is expected to have a broad and concrete knowledge of the common cultural context of the culture that the writer is talking about.
If, indeed, the Book of Mormon is an ancient document then one should not expect it to explain every detail of the culture and environment related to the recorded history. In fact, the lack of detail is a hallmark of an ancient document and gives further support to the historicity of the book.
