You know, of all the types of Time Travel stories there are, the "working paradox", as you put it, is my favorite. However, it does seem that many people, like Vashkoda, have fundamental difficulties grasping the one defining aspect of the concept.

Time is not linear. All of time exists as one unit...there is no beginning and no end. Think of it as a multi-faceted jewel, of which we can only see one facet at a time. The whole jewel is already there, but it is a limit of our perception that makes us think time is linear.

I suppose your love of the working paradox is why you like the first Terminator but not the sequel. I feel the same way. It is probably one of the more famous of the working paradox stories. Another good example is The Philadelphia Experiment, which was more purely focused on the concept.

In case you're wondering, the multi-faceted jewel explanation comes from Alan Moore's Watchmen, which did not really have a time travel element to it, but the roots of the concept were there with the Dr. Manhattan character's ability to perceive all of time within his existence.

Of course, that idea harkens back to poor old Billy Pilgrim in Kurt Vonnegut's Slaughterhouse Five. Of course, that's not really a time travel story either, but it does help explain the concept a bit.

Hope I haven't bored everyone ;-)
