I once heard a tale of a man
who split himself in two. The one part never changed at all;
The other grew and grew. The changeless part was always true,
The growing part was always new, And I wondered, when the tale was through,
Which part was me, and which was you.
from Children of the Mind by Orson Scott Card (1951-)
Read this poem. Write down one insight from it.
Read it a second time. You'll find another.
Read it a third time - and there's a good chance you'll find another insight.
This is why I find OSC so fascinating and talented.
One day, I'll write a blog post about Orson Scott Card (Wikipedia, official site), IMO one of the most talented authors I've ever had the opportunity to read.
He manages to mix theology, xenology, politics, science fiction, physics, geography, and many more fields of knowledge into thought-provoking and hope-inspiring tales.
You can simply read his books (well, I took the audio route and listened to them) and enjoy them - but you owe it to yourself to at least try and notice all of his insights and observations about soooo many topics.
OSC become known when one of his books - Ender's Game - became a feature film - but should you choose to try out on of his books, I'd recommend opting for the Shadow series, starting with the first one - Ender's Shadow.
Check it out. I strongly believe it is worth your time.
