It's a unfortunate truth that one might have to accept, but the fact of the matter is, you have to choose, fate or choice. In the ideal of fate, which is so rigid, everything is governed by that single rule. Which would conclude many things: time and space as we know it is a linier plain of existence travelling in ONE direction. God or some higher force must exist, because if your fate was chosen randomly, such a concept would be useless and would simply exist because we exist. And who is to say that that higher force is not also governed by fate aswell. Which brings to point the idea that perhaps the hierchy of power goes on forever, or that there is one person or thing up there actually making a descision or choice...
Another restriction of fate is that if you were to learn your fate, or perhaps predict it through science, then there would be nothing you could do to stop it. Or more to the point, anything that you would try to do to stop it, wouldve already been in the plan anyway. Fate is all encompassing. Which means that if you were to learn your own, then that would still be within in the bounds of your own destiny. Or more simply, you were meant to learn your destiny. Ultimatly it is a 'total' argument. Meaning that there is no dispute to it's existence.
Now the real question is, is there a purpose. When it comes to infinity, if fate exists, infinity cannot. But only if there is a purpose. A plan for us or the stars and planets or whoever. And for their to be a purpose, there has to be a 'planner' a force that has this plan in mind. I like to call this the force of nature. Something that extends past the world of plants and trees and animals, which transcends even into space and time itself. And knowing the patterns of nature on earth through evolution, we can deduct that the force of nature must be intelligent. It can adapt, it can grow and it can eliminate that which is hindering its progress. Extend this possibility to the idea of space, time and fate, and you have a bonified G-O-D. Knowing this now, there is someone makeing a choice (albiet a very uncompassionate one) to ensure something...or perhaps prepare for something, or even create something.
The idea that there is nothing behind fate would just boggle me, only because there would be there is no meaning to existence at all. We are given a destiny...for what!? But the idea that there is someone running the machine of fate, is hugely ironic, because even if those who govern us are being governed themselves, there must be a top, and end,a big boss. Someone has to be makeing a choice.
