"So basically you're sticking around to watch us all fuck up ?" "Yes. It's one of life's few guaranteed constants." - Iain Banks

It could always all be unreal - how could you ever tell otherwise? You took it on trust, in part because what would be the point of doing anything else? When the fake behaved exactly like the real, why treat it as anything different? You gave it the benefit of the doubt, until something proved otherwise.

They spend time. That's just it. They spend time traveling. The time weighs heavily on them because they lack any context, any valid framework for their lives. They persist in hoping that something they think they'll find in the place they're heading for will somehow provide them with a fulfilment they feel certain they deserve and yet have never come close to experiencing."

I can understand that people want to feel special and important and so on, but that self-obsession seems a bit pathetic somehow. Not being able to accept that you're just this collection of cells, intelligent to whatever degree, capable of feeling emotion to whatever degree, for a limited amount of time and so on, on this tiny little rock orbiting this not particularly important sun in one of just 400m galaxies, and whatever other levels of reality there might be via something like brane-theory [of multiple dimensions] … really, it's not about you. It's what religion does with this drive for acknowledgement of self-importance that really gets up my nose. 'Yeah, yeah, your individual consciousness is so important to the universe that it must be preserved at all costs' – oh, please. Do try to get a grip of something other than your self-obsession. How Californian. The idea that at all costs, no matter what, it always has to be all about you. Well, I think not.
