If you're interested in philosophy but don't have a background in it, check out The Philosopher's Magazine. It's a philosophy version of Popular Science or Discover Magazine. I've subscribed for a year now, and I'm happy with it. It's not mindbogglingly deep, but it also doesn't presume familiarity with lots of jargon, so it's a nice way to stimulate the mind without the frustration of running to the dictionary (or Google) all the time.
