Mortimer Adler, one of the scholars who compiled the Great Books of the Western World, felt the series needed an index, or (as he called it) a Syntopicon. He chose what he thought were the 102 greatest ideas in the history of the world, then hired recent college graduates--eventually a staff of more than one hundred workers--to sift through the Great Books for any allusions in the texts they could find. Among his "great ideas" were Love, Rhetoric, Time, Truth, and Tyranny.
At the time--and ever since--people have questioned his categories. Some complained that Sex, Money, and Power had been ignored. Although War was a category, Peace was not. And there was a lot more Sin than Virtue. Even with the limited number of categories, the Syntopicon eventually reached a length of more than 2400 pages, covered by two thick volumes. A reviewer named Dwight MacDonald wrote a review of what he jokingly called "The Book-of-the-Millennium Club" and trashed the index. "One has the feeling," he claimed, "of being caught in a Rube Goldberg contraption."
When a reporter saw the above picture, originally printed in Life magazine, he was struck by how much the cards stuck in their boxes resembled headstones--"as though Professor Adler and his associates had come to bury and not to praise Plato and other great men."
