I read Thucydides when I was in high school in the early 60’s. One thing I still remember was I would read what one side’s herald would say at a gathering of armies, it would seem clear his side was in the right.
Then I would read the other herald’s speech and I would change my mind. Of course since there was no video cameras back then, both speeches would have been filtered through Thucydides mind, still I suspect the general ideas were retained.
America's so-called "journalists" are in no danger of this.
