Time.
That's the obvious answer to your question of why not go closer to the original source. Reading a whole book to resolve questions of fact is spectacularly inefficient unless those facts are cruxes for crucial decisions.
I wonder if this is one good use of LLM's encyclopedic knowledge. Asking an LLM if there are contradictory accounts to claims of fact would be many orders of magnitude more efficient than reading source books.
When you think about it, most of what we know comes at a remove — many removes often.
Most of what we know in science comes not from going through the experiments ourselves and pondering the results, but from the successive compressions, reevaluations, analyses and reductions of scientists and textbooks.
Most of what we know of history comes not from living it, not even from reading first hand sources, but from reading secondary, tertiary, n-ary literature based on more and more removed sources.
Most of what we know of our philosophies and religions comes not from the direct experiences of the Canon in their original language, but of commentaries, translations, interpretations and adaptations.[1]
And at each such step, the goals, frames, and inclinations of the authors influence what gets dropped, what gets enhanced, what gets transformed.
One of the best ways I know of reminding oneself of that, beyond reading intellectual histories, lies in following a reference or a story back from where it was plucked.
For example, I’m currently reading B. H. Liddell Hart’s biography of William Tecumseh Sherman, the famous Civil War general.
What brought me to this book was not fascination with the Civil War or military history, but instead a passage from Ryan Holiday’s Ego is The Enemy, which I found myself returning to for nuggets of wisdom able to curb my own ego.
(Ryan Holiday, Ego is The Enemy, 2017, p.17-18)
That snippet, and other throughout the book, certainly whetted my appetite to learn more about Sherman. And Holiday included B. H. Liddell Hart’s biography both in the selected bibliography at the end, and in his master reading list on his website:
(Ryan Holiday, Books To Base Your Life on (The Reading List), 2018)
So I got Sherman: Soldier, Realist, American, and started reading, looking for more meat about this story and others of the same time.
Yet when I reached the obvious source for the Holiday passage above, I noticed surprising differences:
(B. H. Liddell Hart, Sherman: Soldier, Realist, American, 1960, p.93)
Clearly, Holiday’s treatment differs from Liddell Hart’s.
In Holiday’s passage, Sherman’s request for not being further promoted only stems from his own estimation of his worth, and his belief that it does not yet warrant superior command.
Whereas Liddell Hart instead frames the utterance in the context of Sherman’s depression; at this point in his life, Sherman had endured many failures and defeats (the most recent just days before), despite having generally been the reasonable realist that took the sensible course.
Another minor difference lies in the characterization of Lincoln’s response: in Holiday it is direct and straightforward, in Liddell Hart it betrays Lincoln's sense of humour.
If Holiday was just blatantly manipulating history to make a point, I would be less curious. But I don’t think this is what is happening here. I’ve read most of his books, followed his adventures for a while, and as far as I can see he is a genuine thoughtful writer who cares about getting things right, and actually read in details the books he leverage in his own work.
Which makes this even more meaningful: even a well-meaning and serious thinker naturally shifts history, ever so slightly, as they retell it.
Why did Holiday change these elements?
My guess is that it comes from a difference in goals between Holiday and Liddell Hart.
The latter is writing a biography of Sherman, and so cares a lot about making sense of the man and revealing his subtleties. Whereas Holiday is writing a book about Ego; what resonated with him in reading about Sherman was his strategic genius and his character.
Similarly, these differing goals impact the amount of space allocated to the incident: it takes a few lines in Ego is The Enemy, but in Sherman it is a full page that builds on many previous incidents that have been recounted (at this point in the biography, we have seen Sherman failing over and over again, and almost give up and go to live in London).
These differences means that Holiday had to compress the story; first to fit into his notecard system, then to fit within the chapter where he used the story.
This is why both Sherman and Lincoln are simplified, almost purified: Sherman distilled to his realism and check on his ego, and Lincoln into the wise president harassed by incompetent and egotistic military officers.[2]
I even think Holiday did a good job here. Despite simplifying and taking some liberties with the context, he still drives home a point that appears repeatedly in Liddell Hart, and which played a role in the original incident.
(B. H. Liddell Hart, Sherman: Soldier, Realist, American, 1960, p.71)
(B. H. Liddell Hart, Sherman: Soldier, Realist, American, 1960, p.76)
(B. H. Liddell Hart, Sherman: Soldier, Realist, American, 1960, p.134)
These extracts and many others from Liddell Hart show that the core point made by Holiday is there in the material; what the latter did was not so much invent a different character as combine these insights into Sherman’s egolessness, fusing them into a neater version of the story that best fitted the general point.
As for Lincoln, if Holiday implies much more wisdom than was really displayed by Lincoln at this time of the war (at least according to Liddell Hart), it is hardly a massive issue here: Lincoln is a side character in this anecdote, used to emphasize the contrasting egotism of the other generals and commanders of the Union.
Yet once again, this is still a distortion, one that I wouldn’t have known had I not read the original sources.
And it gets even worse: for why would I expect the “original” story Liddell Hart’s portrayal to not also suffer from similar problems? Especially given that there are more reasons to doubt Liddell Hart’s use of history.[3]
I could start reading Liddell Hart’s sources, but I most likely won’t. Also, for my own interests, it does not matter that much: I’m more searching for moral inspiration than for the exact accurate story of Sherman’s life.
Still, there are cases where such distortions, even well-intentioned, can be more problematic. The other example which comes to mind is another one from Ego is The Enemy, Holiday’s treatment of John Boyd.
(Ryan Holiday, Ego is The Enemy, 2017, p.29-31,34)
All in all, Holiday presents Boyd as a paragon at egolessness who did everything for his country and got punished for refusing to lick ass.
Yet this is not the full vision that emerges from reading the main biography of Boyd (which is also in the selected bibliography of Ego), Robert Coram’s Boyd:
(Robert Coram, Boyd: The Fighter Pilot Who Changed the Art of War, 2002, p.182-183)
Coram is generally impressed with Boyd’s brilliance, and sympathetic with his subject, but he also noticed and repeatedly pointed out that Boyd’s treatment by the Air Force was not only because he refused to lick ass and compromise himself. Boyd liked to win fights and debates. He liked bravado and rubbing it in when he succeeded. It’s not just that he refused to compromise, it’s that he often went out of his way to humiliate people who fought against him, in the process turning them into enemies.
(Robert Coram, Boyd: The Fighter Pilot Who Changed the Art of War, 2002, p.179-180)
This simplification strikes me as far more problematic than the Sherman one because it removes a dimension essential to the theme of Ego is The Enemy — for what pushed Boyd to search for retribution and final vindication, if not ego?
Going further, what Holiday is pushing here is the story that Boyd was projecting about the choice that needed to be done. And there is an element of truth to that story: doing what is right often leads to issues and conflicts. But by papering over the responsibilities of Boyd in the festering of these conflicts, Holiday hardens the tension between purity and compromise into something that doesn’t fit reality anymore.
And from the perspective of the reader of Ego is The Enemy, there is no cheap way to distinguish between the fine case of Sherman’s treatment and the problematic case of Boyd’s treatment.
I don’t have a final method for addressing this.
Maybe just an obvious thought: if some idea, concept, story particularly resonates with you, why not peel back the remoteness and go closer to the original source?
Religion-wise, this feels slightly less true of say Islam and Judaism, where most practitioners can actually read the original language of the sacred text — but even there so much of the current understanding and living of the religion is filtered through commentaries, analyses, and other supplementary and derivative material, such the Hadiths and the Talmud.
I also expect that Ryan Holiday’s talent for marketing (that is, for memetics) played a role here. He has an ear for making anectodes and observations pithy, and he used it here.
I have not investigated this in detail, and don’t intend to, but scholars have raised claims about his alleged manipulation of history for his own benefit, notably in establishing the Rommel myth.
