Don't forget about Poetry's Square, you all!
Thank you for all of your answers. I'm reeeeelly ready or a trip to the library now!
Concerning Sophie's World: it includes philosophies from both Christian and non-christian believers.
The author discusses Paul the Apostle favorably and St. Augustine unfavorably.
The overall worldview of the book does not point directly to Christianity but CLEARLY indicates that there is a higher power.
I had to draw clear lines at several point, saying to myself, "OK, I don't agree with this part!" but it is still a completely worthwhile read.
I believe that Christians should be thinkers, too! Let us not nestle into complacency!
By the way, the F key is sticking on my key-board. Annoying!
And I LOVE my new "Little Artist" anime thing on the side...
