Telling the truth, the whole truth, and nothing but the truth
The Yated Ne'eman wrote recently that they purposefully do not always give all the biographical details when they write articles and stories on people. They want people to learn a moral lesson and a behavioral style, rather than give the complete and unvarnished truth. Their goal is shaping morals, not being a completely accurate recording of history.
This is in contrast to what Rabbi Nathan Kamenetsky write in the introduction to his book, The Making of A Gadol. Thanks to R. Gil Student and his open access program(yes, I am giving it an advertisement, but it is well deserved), the introduction to the book is available here.
R. Kamenetsky writes about his thinking and the pros and cons of writing history, as opposed to moral storytelling. He quotes R. Shimon Shwab in favor of moral telling, and R. Shwab's brother on the other side. Ultimately, with few exceptions, he comes down on the side of telling the truth as best as he knows. It is too bad his attitude is not more common.
I highly reccomend spending a few minutes and reading what R. Kamenetsky wrote. Not only because of this issue, but insights into other issues as well. Hopefully the entire book will be more accessable soon.
