Great Books LadderIndex

Great Ideas: our index

Pick an idea and follow it through the great books, rung by rung, from the oldest to the newest.

This index is inspired by Mortimer J. Adler's Syntopicon, the index of great ideas in volumes 1 and 2 of Great Books of the Western World, which lists passage by passage where each idea is discussed. Ours is far smaller and our own: 60 ideas, named and grouped our way, each linking to the rungs on this ladder that take it up. It grows as rungs are built. To learn how the Syntopicon itself works, see The Syntopicon and Mortimer Adler.
