Storytelling has been a part of the human experience for as long as anyone can remember — and probably even earlier than that.

It began with the oral tradition, gradually evolved with the written form and then advanced dramatically as technology changed.

In his book, "The Written World: The Power of Stories to Shape People, History, Civilization," Harvard professor Martin Puchner writes about the continuing power of storytelling and why the classics endure.

He joins The Show's Steve Goldstein to talk about it.
