Hello, first time posting, and I thought I would ask about something I recently found out about.
I heard about a set of books produced by the Encyclopedia Britannica, called "Great Books of the Western World", led by Mortimer Adler (who I already liked because of his book "How to Read a Book"). It's a collection of what a team of people called the Great Books of Western Thought, ranging from Homer to Freud. The collection itself is fascinating, but what I found very interesting was what Adler produced with it: the syntopicon.
The Syntopicon is a 2 volume work that tries to list the "important" topics from everything in the rest of the collection, along with links to those works for further discussion (Wikipedia link for more details: https://en.wikipedia.org/wiki/A_Syntopicon:_An_Index_to_The_Great_Ideas). What really intrigues me about Adler's work is this feels like a type of "topical" Zettelkasten, but on some of the greatest works ever known. I'm hoping to at least see the Syntopicon myself (I think my library has a copy of parts of the whole collection), and learn more about it.
Has anyone here ever heard of this work before? If so, do you view it as something similar to a Zettelkasten? I was amazed to find such a thing existed, and wanted to share with others who might like to see more about it.
