" Here's in extreme example: the possibility of life after death. When considered rationally, there is no justification for believing that anything happens to anyone upon the moment of his or her death. There is no reasonable counter to the prospect of nothingness. Any anecdotal story about "floating toward a white light" or Shirley MacClain's past life on Atlantis or the details in Heaven Is for Real or automatically (and justifiably) dismissed by any secular intellectual. Yet this wholly logical position discounts the overwhelming likelihood that we currently don't know something critical about the experience of life, much less the ultimate conclusion to the experience. There are so many things we don't know about energy, or the way energy is transferred, or why energy (which can't be created or destroyed) exists at all. We can't truly conceive the conditions of a multidimensional reality, even though we’re (probably) already living inside one. We have a limited understanding of consciousness. We have a limited understanding of time, and of the perception of time, and of the possibility that all time is happening at once. So while it seems unrealistic to seriously consider the prospect of life after death, it seems equally naïve to assume that our contemporary understanding of this phenomenon is remotely complete. We have no idea what we don't know, or what we’ll eventually learn, or what might be true despite our perpetual inability to comprehend what that truth is. It's impossible to understand the world of today until today has become tomorrow. "
