This is an interesting question, and ultimately I think either way you are doomed. Honestly I think the answer lies in how much your willing to believe about the unknown, and how much you believe about upper dimensions. Human control makes going back to the past very difficult, because if you went back in time your going to want to tell yourself to do something to change your present and future which could erase your ability to go back in time in the first place, or lets say everything works, well you have just changed the present and the future which means you may never need to go back in the past or have the desire to, because life is great, but that would mean you never went which in turn means you forever live in a circular paradox. Seeing the future could be depressing, because it means your future will always be this which means you have to deal with that, and that no matter what depending on what you believe your destiny will be for that to happen. I think this is one of the reasons man kind has not reached a point of being able to mess with the fifth dimension because as a species we cant handle it yet. Even as I write this I would still try to disprove what I just said because I cant perceive anything more than my own cognizance. While a more graduated practice may see time travel as a help to society. I think in order for time travel or dimension hopping to be successful we would need to learn how to think and act in a dimension above our own, which kind of sucks, but that just proves how we are not ready.
I think it's "Howe is upset when he receives the letter" because the first one say how the judges thought his work was fine but it says in the inference that they didn't like it and the 2nd one doesn't really make sense to the inference.
