PARABLES: I love writing short fiction although I'm not really very good at it (yet). One of my dreams is to be able to write parables that teach important truths using simple, everyday allegories -- like many of Jesus' teachings and like Aesop's fables, for instance. The parable is a powerful teaching tool because it helps the listener translate an abstract philosophy into concrete terms which he can later extrapolate from -- abstract to concrete and back to abstract again. In the funneling process some of the initial abstraction is stripped away, but the student reconstructs it later on his own thereby enhancing learning even further.
Mark Aveyard has posted a tidy little parable by CK Chesterton that illustrates the difficulties that can arise from situations in which it is much easier to destroy than to create, when the majority agrees on the means but not the ends.
