So, my friend Yaakov ( http://www.myspace.com/yaakov ) has a blog on his myspace account and he asked an interesting question. Namely, he was interested in the age-old philosophical question of pre-destination and "bechira" or free choice. If one's actions are already known and mapped out by an omnipotent and omniscient G-d, are we still accountable for our actions? Why? Whats the point? Etc...
These are my opinions and do not reflect those of any Rabbi that I have consulted with or any particular philosopher. If they match those of one you are familiar with, then I just got lucky.
Now, see, heres the dilemma. You are trying to comprehend the future from a present tense. If g-d exists in a timeless world then all that is, was and will be exist in the present tense. Time does not progress but rather exists as a singularity.
A little moshul: Imagine being tied to the side of a moving trainthat moves down an infinite track. In addition to being tied down, you are also blindfolded, save for one eye which has a long narrow pipe attached to it. The only vision you have comes from whatever passes through the end of that pipe. Bear in mind that this is the only form of perception you have ever had. You would therefore naturally assume that this is all that perceiving is. How would know to assume that if the pipe were removed you could see all the vast scenery in one panorama?
This is the human perception of time. We experience it in a progressive fashion as dictated by our natural laws of physics. As Einstein's thesis on special relativity points out though, time progression is not uniform. At high speeds or excessive forces of gravity, time comes to an almost complete standstill when viewed relatively to a body at rest or in moderate gravitational fields.
More importantly, what this indicates is that time is a whole. It is a continuum that is only particularly viewed as progressing in the forward direction due to the laws of entropy. We look at the stars and see dots of light. The vision of the star as it is now at this moment. In the true sense of space-time though, stars are long spaghetti-like strings, with one end being a large gas cloud and the other being an exploding supernova. So to humans, in the true time sense, are long worms with baby legs on one end and old-man legs on the other. Time progression is simply a perception, much in the way that the eye perceives color. It is not a physical property but rather a cognitive translation.
This does not change free-will however, or at least it does not demand it as you might assume it would. Our actions are still our own. We perform them and are accountable for them. Just because they can all be viewed, beginning to end, simultaneously by a timeless g-d, does not remove our accountability for them. That is again, merely a perception of ours, bound as we are within this progressive constraint.
