|Flatland : A Parable of Spiritual
Dimensions, Edwin A. Abbott
"Published in 1880, this short fantasy takes us to a
completely flat world of two physical dimensions where all the inhabitants are geometric
shapes, and who think the planar world of length and width that they know is all there is.
But one inhabitant discovers the existence of a third physical dimension, enabling him to
finally grasp the concept of a fourth dimension. Watching our Flatland narrator, we
begin to get an idea of the limitations of our own assumptions about reality."
