Bedeviled: A Shadow History of Demons in Science

Jimena Canales

3.77 · Rating details · 26 ratings · 7 reviews

How scientists through the ages have conducted thought experiments using imaginary entities--demons--to test the laws of nature and push the frontiers of what is possible.

Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischi ...more

Nov 03, 2020 Eve rated it it was amazing

This modern demonology for the age of reason offers at least one mind-altering epiphany a chapter. I generally assume histories of science will be too dry for me. But Bedeviled is so felicitously written that my only struggle in getting through it was my need to savor so many sentences. It leaves me with a new understanding of how imagination shapes science and progress, and with a desire to read more by this author and in this genre

This was the first book I received in the science-based book-box from 51st Street Seminary Books in Chicago.
And I was a bit surprised when it arrived. For a popular-science litbox I was expecting: popular science. Not social histories written through the lens of a historian. Nevertheless I went into this with as open a mind as possible.

And I was a bit surprised when it arrived. For a popular-science litbox I was expecting: popular science. Not social histories written through the lens of a historian. Nevertheless I went into this with as open a mind as possible.

Unfortunately, even before the main text started I was starting to worry. After finishing the introduction I got the impression that Canales intended to pathologise constructs in thought experiments and the way science approaches the unknown. There were some strange hyperbolae, e.g. "To catch them [demons], scientists must think like them." And I know this was meant in terms of planning for the unknown but it sounded so ominous. At the end of the foreword Canales writes about creating a "Modern demonology for the twnetieth century", which in this context seems absolutely contrived: unless she meant to factor scientific mishaps into this? (spoiler: she doesn't).

The further I read the more frustrated I became. The author seems prone to hyperbolae and repetition. Her prose is clouded with peripheral quotes backing up every single statement made. For example in Chapter 3, Maxewell's Demon, the first 3 pages of the chapter serve to convince the reader than Maxwell was a big deal, but I'll be damned if there's an ounce of content in the entire thing. When we actually get around to describing the 'demons', and the hole in our knowledge they attempt to plaster over, the scientific question they're associated with is again seen through the obsfucated eye of a historian. I found myself more confused leaving the chapter than entering it.

For the rest of the book Maxwell's demon resurfaces again and again. The most cringey moment for me was the bit about daemon programs: that literally are just programs running in the background on a computer. In Canales's frame though we get a goose chase going from the imitation game to machine learning. The whole book reads this way and it's exhausting.

I will say that some of the actual content, when we got to it, was new to me and interesting, e.g. King James's demonology.
I started skimming this book after the 50 page mark. Cannot recommend.

[Here's an excerpt of the review I wrote for Nature magazine. Please check out the whole essay here: https://www.nature.com/articles/d4158... ]

The workings of powerful computers, the processes of evolution, the market forces that drive the global economy. To conceptualize such unseen forces, researchers have long invoked thought experiments involving demons, devils, golems or genies.

These strange beasts aren’t creatures of superstition and pseudoscience. They are useful ideas that have had an im ...more

A very original take on the history of science. Studying the analogies scientists use sheds light into the creative process of scientific discovery. I liked the approach, it kind of feels very novel, like a new way of thinking about science.

I have a doctorate in the History of Science and teach science at a university. The best things about history of science is its ability to teach science by taking you through the process of how it was created. The history of science is invaluable this way. I am an old hat at most of these ideas, but my understanding was deepened by reading the thought processes from which these concepts arose. It is better to be "shown" than "told."

There are some truly terrible history of science books that don' ...more

Shelves: history, physics, science

This is a good book for history but not as much for the details of the thought experiments themselves (at least from a math/physics detail perspective). I admit that I was hoping for a more technical read with a deeper dive into the various "demons", which led me to have different expectations for this book. Canales starts with Descartes' thought experiment (brain in a vat, essentially), goes on to Laplace's demon, and mostly stays with Maxwell's demon for the rest of the book with forays into d ...more

Descartes' philosophical demon, Maxwell's sorting demon, Laplace's statistics demon, and even Darwin's genetic demon - were all as important in the theories of these thinkers as were their intellectual observations of the physical world
⚛️
The book is quite heavy on the scientific side, and it takes a while to absorb the laws and theories that are the sidekicks in this book to the demonic protagonists, so I would recommend this to anyone who loves everything science and is looking to explore the old and new ways of thinking
⚛️
I absolutely loved the audiobook narrator, Peter Berkrot. He was just perfect for this book, with his Ramsay Bolton-like voice and accent, making the story of demons all the more real!
