heh, I like to read to expand my view on the world, so I'll read materials that take opposing views and still enjoy both...

As for sleeping, yeah, I guess Plato could be boring for some, but ANY book could be boring for some people... Personally, I think Art of War will put you to sleep faster than The Republic... philosophy books, I mean what can I say, some people can barely read a Dr. Seuss book without falling asleep...
