"All the novels below ask you to think. They cover many of the major philosophical fields: epistemology (what we can know), metaphysics (the nature of reality), ethics (how we should live), aesthetics (art and what is beautiful), political philosophy (how we organize society), and the philosophy of religion (faith, the existence of God, the problem of evil). The wonderful thing about philosophical fiction is that it covers all these fields, but does so through the trappings of fiction: character, plot, setting, etc. These novels make philosophy approachable and fun."
