[quote name='gags' post='124001' date='Sep 2 2006, 10:26 AM'] Notwithstanding occasional instances of deja vu (which are easy enough to explain) I don't see any evidence of an "eternal return". [/quote]
I think you miss the point. You can have no visible evidence for the eternal return any more than you can have visible evidence for mathematics or logic. Certainly it is self-evident that either a proposition is true or it is false, but you can never see truthiness in a proposition. In the eternal return, you would have no knowledge of a previous instance of having done an action X, because if you did then the current experience would differ from action X. Ex hypothesi, every time an action occurs it occurs exactly the same way. So even though you have never perceptually experienced an eternal return, evidence for it may be forthcoming.
[quote name='Bold Standard' post='124006' date='Sep 2 2006, 12:37 PM'] I'm not an expert on the field or anything, but I read about quantum physics for fun a lot, and I've never seen anyone credible take this theory seriously. From what I remember, even Stephen Hawking in A Brief History of Time is dismissive of it, although he does explain the theory-- and usually he's pretty "open minded" about far-out sounding cosmological hypotheses.[/quote]
I would be very surprised if Hawking rejected the notion out of hand, unless he had some direct evidence against it that I am unaware of. Otherwise, I would more likely expect him to reject Nietzsche's metaphysical arguments for the idea (and so not necessarily reject the idea itself), which are typically considered weak, though the only criticism I've seen seems itself to be weak.
[quote]But, as far as I understand, this idea (in metaphysical terms) is an extension of the expanding/contracting universe theory, which seems to me to have some pretty fatal flaws in itself.[/quote]
Oh no, no, no, no, no. Totally different subject. Nietzsche wasn't even around when scientist knew that the universe was flying away from itself. For him, the cosmological idea of eternal return was more static: The universe is; the universe was; the universe will always be. Nietzsche was not a materialist and did not feel compelled to explain how the actions to come in the future would necessarily need to wrap back around to the actions that have happened before in any detail. His claim was largely based on the idea that, because beings and their order are limited while time is not, any given order throughout any give period of time must recur some time. I find this a dubious argument at best.
One person argued against it thusly: Imagine you have two wheels rotating on the same axis. Both have dots on a point at the top of them when they are in the initial position, and these dots line up. If the first wheel has diameter d and the second has diameter d(pi), then when rotated at the same speed, they will never again line up. I take this argument to be dubious as well, because I question the accuracy of irrational numbers to quantify real-world action. My argument would be more akin to: Imagine the two wheels are set up in the aforementioned way. Then imagine that the wheel-maker breaks them with a hammer and then kills himself with the very same hammer. The alignment will now never recur.
But just because this argument fails doesn't mean other ones will.
[quote]I think it also assumes the Big Bang, which I'm skeptical of as well.[/quote]
I used to be as well, but now I'm more equivocal about it.
[quote]As far as the moral implications are concerned, I don't see why this would make any difference to a person's decisions. I would think that you could make just as strong an impression with, "You've only got one chance to get this right," as you would with the (imo, totally arbitrary) assertion that they're doomed/blessed to have an infinite repetition of chances that are determined, and in which they probably won't remember ever having experienced these things before.[/quote]
This is definitely an argument in the right spirit. But are you sure it would not bother you to know that, in committing a wrong act, it will be emblazoned in a "time-slice" of you for the rest of eternity? Your point has a certain force behind it, but I cannot help but think, "I had better do the right thing so that, for so long as I experience this life, I feel as happy as possible."
[quote]But, if it motivates you-- that's great. I doubt Nietzsche was trying to achieve much more than that. [/quote]
Scholars debate it. I could see either way being true.

I don't think he's ever made a point just once. As the German saying goes, for something to happen just once is as well as if it never happened at all.

A serious problem with the eternal return, as described, is that it offers no objective standard for determining right and wrong behavior.[/quote]
Perfectly right, Nietzsche always wanted people to figure out the specifics of morality on their own. Here he is simply arguing for integrity, not evading anything.[/quote]
