Necessity by Jo Walton

"Necessity" is the third book in a philosophical science fiction series that follows the residents of a distant planet created by the goddess Athena to experiment with Plato's ideal society. The story takes place generations after the founding of the city, where gods, humans, and sentient robots coexist. The narrative explores complex themes such as the nature of choice, the existence of gods, and the development of societies. When the planet faces a potential existential threat, its inhabitants must grapple with their destiny and the implications of their existence within a universe where the lines between myth and reality are blurred.

The 11214th greatest book of all time

Ranking Details:

Our ranking system awards points to books based on their appearance and position on curated lists. Here's how it works:

Unranked Lists: For lists without specific rankings, each book receives points equivalent to the list's weight. This approach recognizes the book's inclusion on prestigious lists.

Ranked Lists: Books on ranked lists receive points in two ways:

  • Base Points: Initially, every book is awarded points equal to the list's weight, acknowledging its significance.
  • Bonus Points: Additionally, books earn bonus points based on their ranking. The total bonus pool, equal to 100% of the list's weight, is distributed among the books, with higher-ranked books receiving more points.

Exponential Distribution: The distribution of bonus points follows an exponential model. This means the top-ranked book (#1) receives significantly more bonus points than those further down the list (e.g., #100). Our algorithm ensures that higher placements are rewarded more generously, reflecting the achievement of a top rank on any given list.

This scoring system ensures that each book's ranking reflects both its presence on multiple lists and its positions within those lists, providing a comprehensive measure of its acclaim and popularity.

Total Points: 3

Since this book was first published in 2016, there is a penalty of 67.2%. The age adjusted score is 0.98.

This is to prevent newer books from reaching super high on the ranked list of the greatest books of all time. The greatest books should also stand the test of time.
