Observable+Universe

What our minds interpret as reality. Since we can not physically process every existing bit of information, our sight is limited by our physical constraints. Therefore, what we experience is never the whol story, so our perspectives are inherently flawed. This brings up Descartes' Demon, and the question of cogito. Since any external force can manipulate your senses, your body, the only thing you can even begin to rely on is your mind. I think, therefore I am. The mind is the only thing you can trust, because the alternatives are worse. Even though our minds and bodies are flawed, with our minds, we can glean into nature's secrets and artificially construct a reality to our convenience.
