There is a further temporal fact about a given event: whether it is in the past, in the present or in the future.
In the past, present or future of what?
Of me, who is saying it? But that is merely a temporal fact of the first kind: the given event is in the past/future of the event of my saying whether it is in my past/future.
The point of A-theory is that past, present and future are non-relational. There is an objective fact of the matter about which slice of the space-time manifold is the present, although this fact keeps changing, of course. So yeah, one way to think of the difference between A-theory and B-theory is that the B-theorist thinks of past, present and future as relational terms. Just saying "past" isn't enough, you need to specify what it is in the past of. But the A-theorist thinks it makes sense to talk of past, present and future simpliciter.
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.
