Gah! I just got my thinking abilities back! But I'll have a shot. And to forestall any complaints, criticisms, etc., this is from a purely non-religious point of view.
I think that nothing is ever predetermined. It's like the whole parallel universes thing. Say you start at Point A on Line A. You have Choices A, B, and C, all going to a different line. Now, say you choose Choice C. You are now on Line C, which again has Choices A, B and C. You have now entered a completely different universe than the one you left. Each choice you make leads you into a differnt universe, and there are so many choices that from almost the very beginning, there are infinite universes available to you. What you thought was just one of these choices. If you had not seen the red chair, you would have gone through a completely different set of choices and never posted this thread. If you had touched the red chair, you would have gone through a completely different set of choices. If you had shared a banana with your pet monkey instead of looking at the red chair, you would have gone through a completely different set of choices. So I guess what I'm saying is, your future is what you make it, not something predetermined by a higher power.
