[Guille]

But the fact that our mind makes us think that the universe is out, implies that the universe is out, because the mind itself is thought, so the thought of the universe is out is the mind, and thus, the universe out. But no, because it is the fact that the thought is part of the mind, which implies that the universe is out, thus, the universe is out because it's in. But again we come to this same place. Thus, determining whether the universe is out or in is an infinite circular paradox. Any solutions?
