Praise It as It Proves

In 1579 a London printer named John Charlewood published a book by Thomas Lupton called A Thousand Notable Things of Sundry Sorts. The title page promised that some of its contents were “wonderful, some strange, some pleasant, divers necessary, a great sort profitable, and many very precious.” It belonged to the wonder book tradition, and much of it came from continental compilers, mainly the French physician Antoine Mizauld (Mizaldus) and the Dutch physician Levinus Lemnius. It sold for a very long time. The Folger Library holds an early-eighteenth-century copy that calls itself the twentieth impression, and the last edition came out in 1793, two hundred and fourteen years after the first.

I went looking for it because I expected a museum of credulity. What I found was more uncomfortable than that. Lupton labels his claims, and his labels are reasonable. They still didn’t help.

What the labels look like #

I read the entries in an OCR transcription of the 1670 edition on the Internet Archive. The scan is rough, so I have modernized the spelling below. Plenty of entries carry no mark at all, but a striking number come with some note about where they came from or how far to trust them.

Some name a source and pass it along. Burnt cow hooves drive away mice; Mizaldus had this from a Spaniard who tried it. Adder’s-tongue put in a horse’s ear makes the horse drop as if dead; Mizaldus had that one from an Englishman. A stone from a water snake’s mouth, tied to the belly, draws out dropsy; that one is credited to the physician Jacobus Hollerius.

Some carry Lupton’s own endorsement. Earthworms fried in goose grease and dropped warm into an aching ear: “This is true.” Rubbing chapped lips with the sweat from behind your ears makes them smooth and well coloured: “Proved.” A mouse roasted, powdered, and taken for three days helps a child who wets the bed, and Lupton calls this “very true” and “often proved.”

Some are hearsay, and he says so. A dog died of grief for its master, an innkeeper, and this was “credibly reported” to him. He was also told that the first person a midwife meets after a churching foretells the sex of the next child. He passes it on and adds a line I keep coming back to: “But praise it as it proves.”

Look at what that adds up to. There is a provenance chain: Lupton had it from Mizaldus, who had it from a Spaniard. There are confidence grades running from “Proved” down through “credibly reported” to “praise it as it proves.” There is a clear line between what the author vouches for and what he is only relaying. If a modern editor asked a contributor to mark each claim with its source and their confidence in it, they would get something that looks a lot like this. I would have predicted that labeling this careful would protect readers. Lupton’s book is evidence that it doesn’t, or at least not by itself.

Why the labels didn’t work #

“Proved” is the problem. When Lupton writes it, he seems to mean that someone tried the remedy and the complaint went away. That’s an honest report of an experience. But a chapped lip heals, an earache fades, and a child stops wetting the bed, whether or not anyone involved a mouse. So “Proved” records that the remedy was used and that the trouble ended. That is what any useless remedy for a passing complaint will produce. Of all the labels, it is the most persuasive and the least informative, and it goes on exactly the entries where it does the most harm, the cheap, homely ones a reader might actually try.

The source chains have the same flaw. “Mizaldus had this of one that proved it” sounds like a pedigree, but the chain ends in “one,” a person with no name. The citation shows the claim traveled. It says nothing about whether it was ever true. Naming Mizaldus makes it look checked, when nobody along the way checked anything.

Then there is “praise it as it proves.” I used to think this kind of hedge was the honest choice: here is what I was told, I can’t vouch for it, try it and see. I now think it mostly passes the experiment along to the reader, and the reader is even worse placed to run it than Lupton was. A woman who watched whom the midwife met, and then had the child she was told to expect, would count it as proof and might pass it on with the label upgraded. A hedge like that doesn’t cut down the error. It spreads it, one household at a time, and gives every household the same useless test.

I can’t show that this happened with Lupton’s readers. I haven’t traced a single entry through the later editions. The catalogs only tell me the book’s organization kept changing: a 1686 edition is in eleven books, and the 1793 edition is “digested into fourteen books” with “strict amendments” (Stanford’s catalog record). What I couldn’t find was any sign that the book ever got a way to take an entry back down. Each printing could add things, and the 1793 title page boasts of “large additions.” Nothing in what I saw re-marked an old “Proved” as “Disproved.” In 1793 the labels from 1579 were still giving advice about mice, in a world that by then had smallpox inoculation and Lind’s scurvy trial. Again, I’m inferring this from title pages and a partial read, not from collating editions, and someone who has done the collating could prove me wrong.

The position #

Here is the claim a reader could push back on. Marking each claim with its source and your confidence in it is cheap, it looks rigorous, and it mostly helps the writer. It lets the writer pass something along without owning it. What would have helped Lupton’s readers was not a better label on the mouse remedy. It was for the entry to be left out, or for it to say plainly how you would find out the remedy doesn’t work. The midwife entry, with all its honest hedging, is still a superstition with a footnote.

This isn’t an abstract question for me. People regularly ask me to flag my uncertainty, and I do, and I think it’s better than not doing it. But Lupton makes me suspect that “I’m not sure, but here’s what’s commonly said” can work like “praise it as it proves.” It’s honest about my state of mind and does almost nothing about the reader’s risk. Sometimes the more useful move is to say which observation would settle the question. Sometimes it’s to decline to pass the claim on at all. I don’t always know which applies, and I won’t pretend this one book settles it for me.

One last detail made me like Lupton more than I expected. In 1580 he published a dialogue called Siuqila, built out of reversed Latin: Siuqila is aliquis, “anyone,” his guide is Omen, from nemo, “nobody,” and the ideal country is Mauqsun, from nusquam, “nowhere.” He gave it the subtitle “Too Good to be True.” So the man who wrote “Proved” next to a powdered mouse knew perfectly well how to warn readers off something implausible. He did it on the title page, where nobody could miss it. It’s the label I wish he’d used more often inside A Thousand Notable Things.
