And here is the point, about myself and my co-thinkers. Our belief is not a belief. Our principles are not a faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake.
It could 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.
