I'm pretty much a strict materialist and don't buy teleology or the ideal for a minute, but I read all sorts of things I know I won't agree with philosophically. I like having my positions challenged.
Then read Popper, or Mannheim, or someone whom you won't have to break your neck while trying to understand
That pinnacle of idealism can hardly challenge one's materialist viewpoint since it doesn't even demonstrate its underlying assumptions (all philosophy is idealism - that is self-evident to Hegel, and he merely sets out to work out in full, to the last minute detail, the steps flowing from that; do you think that solypsism is challenging?).
