When you point out some of the less appealing aspects of ancient societies, someone usually accuses you of anachronistic morality. For example, it is very hard to find a writer in the ancient world who objects to slavery as a malum in se. There were people who objected to the wrong kind of people being enslaved, or to cruelty to slaves, but there are very few surviving texts where anyone says that slavery is wrong in and of itself. Isn’t it unfair to accuse the ancients of not knowing that slavery was always wrong if none of them seems to have realized this? There are various counters to this, like pointing out that people who point out admirable aspects of ancient societies seldom face the same criticism. But the best counter is listing some ancient practices which other ancient people objected to. One of the central themes of Roman literature is complaining how terrible Romans in the author’s day are.
If you spend enough time in academic circles on the Internet, you find passionate statements that providing free peer review for for-profit journals is exploitation. I have heard this from a distinguished Roman Army scholar who has not been well-treated by his academic employers, and on the birdsite you can find things like this:
Nathan C. Hall: “Please RT if you have ever conducted a manuscript review for a journal while not employed in a tenure-track/permanent academic job. As many peer reviews are done by precarious academics (grad students, postdocs, adjuncts), lack of compensation is basic exploitation.” https://twitter.com/prof_nch/status/1039322066263138304
Now, in my time as a graduate student I have peer-reviewed one journal article, and reviewed half a dozen manuscripts from friends, and I have to say that the claim I am being exploited is absurd. Any wise writer sends their writing to a few trusted friends before they send it out into the world. This is such a basic feature of academic life that academia dot edu built a whole module for it, Princeton and Stanford host a series of Working Papers in Classics, and an Australian economist posts drafts of his books one chapter at a time on Google Docs with invitations for readers of his blog to comment on them. When I agree to comment on a friend’s manuscript, asking them for money would be as offensive as inviting them to my apartment for dinner and then sticking a credit-card reader in their face. Trading favours is a basic part of social relations between equals. As scholarly authors, we read other people’s work (and cite it or review it) so they will read ours. Reading yet another article on a subject is tiresome, but we do it because sometimes it will be our article on someone else’s desk when they really want to go to bed and the recycling bin is so very very close.
