So these facts about an event are subjective: they depend on when in time you are when you are making the judgement.
You're describing a B-theoretical perspective. An A-theorist will disagree with this characterization. Many A-theorists believe that the only objects that exist are present objects. So time isn't like space, where "here" is "here" rather than "there" simply because you happen to be "here" and not "there". You could have been "there", in which case "there" would have been "here" for you. Time, A-theorists claim, is different, because you couldn't be located anywhere (anywhen) else except in the present. It's not that the present is the present for you because you happen to be there; it's that the only time at which objects exist (and, by extension, you could exist) is the present. So it's not like there are other people who exist at other times, for whom the present is different.
Don't ask me to defend this view, though, because I think it's nuts. A-theory vs. B-theory is one of those philosophical debates which should be declared closed. B-theory has clearly won.
I don't think anyone's made A-theory consistent with special relativity. But you can bodge general relativity/cosmological models a bit to get something that looks a bit like A-theory by insisting on a preferred foliation (e.g. look at spacelike surfaces with constant proper time since the Big Bang, and count everything on one such surface as the "real now")
Despite being (IMO) a philosophy blog, many Less Wrongers tend to disparage mainstream philosophy and emphasize the divergence between our beliefs and theirs. But, how different are we really? My intention with this post is to quantify this difference.
The questions I will post as comments to this article are from the 2009 PhilPapers Survey. If you answer "other" on any of the questions, then please reply to that comment in order to elaborate your answer. Later, I'll post another article comparing the answers I obtain from Less Wrongers with those given by the professional philosophers. This should give us some indication about the differences in belief between Less Wrong and mainstream philosophy.
