But are we within likelihood? Batra asked. Are we even still within the realm of anything other than paranoid lunacy? - Iain Banks

Roundly insulting one’s superiors behind their backs was one of the perks of being inferior, Choubris held.

The Truth was the presumptuous name of the religion,…It arose from the belief that what appeared to be real life must in fact—according to some piously invoked statistical certitudes—be a simulation being run within some prodigious computational substrate in a greater and more encompassing reality beyond. This was a thought that had in some form, crossed the minds of most people and all civilisations…. However, everybody—well, virtually everybody, obviously—quickly or eventually came around to the idea that a difference that made no difference wasn’t a difference to be much bothered about, and one might as well get on with (what appeared to be) life.

Everybody seemed to live as though things were always just about to get better, as though any bad times were just about to end, any time now, but they were usually wrong. Life ground on. Sometimes to the good, but often towards ill and always in the direction of death. Yet people acted as though death was just the biggest surprise—My, who put that there? Maybe that was the right way to treat it, of course. Maybe the sensible attitude was to act as though there had been nothing before one came to consciousness, and nothing would exist after one’s death, as though the whole universe was built around one’s own individual awareness. It was a working hypothesis, a useful half-truth.
