We read to know that we are not alone

I wonder why I write, or what the point in writing is. Can I call myself a writer? What can I call myself? By my name, the one my parents named me before getting to know 'who' I was? It was a loaded name, stuffed with their own hopes, dreams and vicarious aspirations for a baby. I really don't know. I am reminded of the movie 'Shadowlands' the story of the great author (back in a time when far more people read I would suspect) C. S. Lewis. In the film, which no doubt is a dramatization and certainly does not retell the literal event I am referring to, one of Lewis' regularly tardy pupils in college tells the story of his father and his view on reading. He stated that 'we read to know that we are not alone.' Again I am sure this did not come from the mind of Lewis or one of his actual pupils. And perhaps I am too hard on screenwriters whom I regard as not even third rate writers. But in this case, the writer hit a very deep and profound vein of truth or at least of pondering. But is it true? I don't know. But if it were, I would like to know the company we are keeping and on what basis we are 'knowing' we are not alone.
