This is, however, not an idea implied by the answers. The answer just imply that we might be able to fix certain things better at a certain point in time.
Fix is fix, but I think I know what you mean. There are some things that it is reasonable to be able to fix, without time travel... so if you are offered time travel, naturally you are going to apply that mindset to the problem.
Well, the first question to you would be:
Do God and his wife Wisdom intend us to fix/manipulate anything at all, or is the implication of your argument that since everything is exactly as God and his wife Wisdom intended it to be it´s not our job to fix anything?
This is interesting. It's as if the nature of life is that time travel is out of the question. Otherwise, Wisdom would have to second guess herself and send some people to more than one time. I wonder why we don't guess as much (why we don't guess that time travel is impossible)?
If Man were meant to live in more than one time, at a time, he would be born less of a man.
If you feel that God and his wife Wisdom intend for us to fix stuff, it seems that we can use all means that are to our disposal. If - as is the premise of your scenario - time travel as a means to fix/manipulate things is to our disposal I fail to see why time travel (of all means that are to our disposal) would be against God´s and his wife´s Wisdom will.
However, if you feel that we should abstain from fixing/manipulating things, I don´t know what to say.
No well its just curious... I think time travel may be a bi-product of our inflated egos, that if we can handle this time we are in, maybe we could handle other times as well. But the reality is that this is not the case. We were born for this time and this time only and if we wanted to change it, we would have to change it from here and if we liked how we changed it, we would have to stay where we are, in which case, either way, we don't time travel.
I wonder why its not impossible to dream these things up though? It's like Wisdom has no fault with us imagining we could travel to other times, its just that we can't actually do it. Maybe the problem is that the relationships are too limited, like if you could summon enough power to change the whole universe into another time period, then it would work, because you would have no opposition from anything to prevent it from coming to pass. You would still feel like living in the past though...
