Between the idea
And the reality
Between the motion
And the act
Falls the Shadow

— T. S. Eliot, "The Hollow Men"

A passage quoted here on this date in 2005—

Douglas Hofstadter on his magnum opus:

“… I realized that to me,
Gödel and Escher and Bach
were only shadows
cast in different directions
by some central solid essence."

This refers to Hofstadter's cover image:
