Change..

On stone were the first thoughts engraved
Then on leaves and lambskin
Afterward came paper, smooth and white
Now it's the text editor.

Chisel and clay gave way to
Stylus and pigment; then
Pen and ink, now the pen is not mightier
Than the keyboard.

Thoughts of great men and women
Were treasured in books.
Now anybody's thoughts can be stored for
Eternity - in the web of global consciousness.
