An odd little detail: In Debt, anthropologist David Graeber mentions that Auguste Comte founded a Religion of Humanity “replete with vestments where all the buttons were on the back (so they couldn’t be put on without the help of others).”

I find this mentioned also by philosopher John Gray, but I haven’t been able to confirm it.

11/16/2023 UPDATE: Reader Fabienne Gallaire very helpfully found some more details. Comte was a disciple of the political theorist Henri de Saint-Simon, who had envisioned a religion of reason in which scientists formed the clergy. This article mentions “le fameux costume tricolore, incluant le gilet boutonné dans le dos”; here’s the costume (worn by Barthélemy-Prosper Enfantin, who helped to propound “Saint-Simonianism” after Saint-Simon’s death in 1825), and here’s the robe in particular. I find a bit more in Christine Gruwez’s 2011 book Walking With Your Time:

In his last work, published in 1825 — Nouveau Christianisme — Saint Simon describes, right up to the smallest detail, the practices of this new religion, dress code included. … John Gray mentions here the bizarre detail of a specific moment when the ‘priest robe’ that went with this new religion was designed in such a way that all the buttons were at the back of the robe, thus making it impossible to dress and undress by oneself. The purpose was that one had to do nothing but appeal to the help of his fellow man, whereby solidarity was the message. It was not unusual for this display of solidarity to take place on the public road, which led to all sorts of amusing scenes. The garment was prohibited in the end by police decree.

(Thanks, Fabienne.)

Yale economist Paul Krugman published a curious paper in 2010: “The Theory of Interstellar Trade”:

This paper extends interplanetary trade theory to an interstellar setting. It is chiefly concerned with the following question: how should interest charges on goods in transit be computed when the goods travel at close to the speed of light? This is a problem because the time taken in transit will appear less to an observer travelling with the goods than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved.

He added, “While the subject of this paper is silly, the analysis actually does make sense. This paper, then, is a serious analysis of a ridiculous subject, which is of course the opposite of what is usual in economics.”

(Paul Krugman, “The Theory of Interstellar Trade,” Economic Inquiry 48:4 [October 2010], 1119-1123. See The Telltale Mart.)

Preparing a time capsule in 1939, the Westinghouse Electric & Manufacturing Company asked Albert Einstein to compose a message for the people of AD 6939. He sent this:

Our time is rich in inventive minds, the inventions of which could facilitate our lives considerably. We are crossing the seas by power and utilize power also in order to relieve humanity from all tiring muscular work. We have learned to fly and we are able to send messages and news without any difficulty over the entire world through electric waves.

However, the production and distribution of commodities is entirely unorganized so that everybody must live in fear of being eliminated from the economic cycle, in this way suffering for the want of everything. Furthermore, people living in different countries kill each other at irregular time intervals, so that also for this reason any one who thinks about the future must live in fear and terror. This is due to the fact that the intelligence & character of the masses are incomparably lower than the intelligence and character of the few who produce some thing valuable for the community.

I trust that posterity will read these statements with a feeling of proud and justified superiority.

The message was recorded on microfilm and resides 50 feet below Flushing Meadows–Corona Park in New York City.
