Atheists & Agnostics

which is why I am an atheist.

On a deep philosophical level, however, things are not always so cut and dried, which leaves room for entertaining creative speculation. For example, given a sophisticated enough computer simulation, occupants of that simulation should not realize that they are part of a simulation programmed by a Giver Of Data, who enjoys watching his program run. Would there be any evidence of the existence of an "outside world" from inside the simulation? Is there any evidence to support the "biological brain" hypothesis from within a dream? While in a dream, go where you will, examine anything you like, and you will never find the brain that is dreaming the dream.

From the perspective of science, that's all unsupported nonsense, of course. But from a philosophical perspective, it's fun to speculate about.
