Chapter 5 - Time After Time

Today's beach musing included a discussion of what makes a book timeless. The definition of "timeless", according to Dictionary.com, is
1. without beginning or end; eternal, everlasting and
2. referring or restricted to no particular time.
Apparently people much smarter than I have debated this very subject and have even given lectures about timelessness in literature.
Here is what they have identified:
A timeless story is one that contains the emotional truths of life.
The story must be enduring and have a core emotional experience that transcends any period of time.
Some examples of timeless books might be -
The Outsiders by SE Hinton - How can the reader not feel the pain Pony Boy does when he loses his best friend?
Pride and Prejudice by Jane Austen - All the hurt, anger, and shame Elizabeth feels when shunned by Darcy can't help but hit the reader in the heart.
To Kill a Mockingbird by Harper Lee - The fear that both Jem and Scout have coming home from the school pageant is palpable to the reader.
Jane Eyre by Charlotte Bronte - The reader admires Jane's indomitable spirit even when confronted with the most difficult of circumstances.
The Wizard of Oz by L. Frank Baum - Dorothy's struggle to find her home and support her friends has the reader cheering her on throughout the book.
