It's a rather ominious photograph, glowering and harsh, not a picture of someone with whom we might want to be best friends.  Oddly, however, Sigmund Freud's ideas about the human being remain, in some form, with us even today.  As we learn steadily more about how much our upbringing influences us throughout our life, even into our older years, we realize some truth in his observations.
     For Freud, we consist of an id, ego, and superego.  In essence, the id is "us," an "us" over which the ego and superego are doing constant battle.  The ego represents our socialization, the superego our "conscience."
     Why is this important?  For Freud, who was a life long atheist (he died in 1939), who we are is the product of our influences.  Because everything outside of us is always shaping us and "we" are therefore never the same, we may not even have a real "self."
     Yet every one of us will acknowledge that we are a "self."  We will say that we are a specific human being.  In the absence of a God, however, maybe this isn't so straightforward.  If we are simply a subjective and unplanned whim of the cosmos, then we are indeed where we live and nothing more.
     On the other hand, in the presence of a God, we are the work of intentionality, subjective still, yet subjective in an objective framework, a framework of purpose and meaning.  We are concrete points in a meaningful universe.
     Sure, without a God we are concrete points, but we are like points on an infinite line:  a self that never really happened:  id, ego, and superego become no more than subjective responses to a subjective event.  An event, we add, that had no reason to happen other than that it did.  And if we insist that we can live this way, we fool ourselves:  meaninglessness will never bequeath meaning.
