Therefore, in order to pin down reality as reality, we need another reality to relativize the first. Yet that other reality requires a third reality to serve as its grounding. An endless chain is created within our consciousness, and it is the very maintenance of this chain that produces the sensation that we are actually here, that we ourselves exist. But something can happen to sever that chain, and we are at a loss. What is real? Is reality on this side of the break in the chain? Or over there, on the other side?
