I believe that we are all ultimately alone and that any deep and lasting human contact is nothing more nor less than a necessary illusion—but at least the feelings which we think of as "positive" and "constructive" are a reaching out, an effort to make contact and establish some sort of communication. Feelings of love and kindness, the ability to care and empathize, are all we know of the light. They are efforts to link and integrate; they are the emotions which brings us together, if not in fact then at least in a comforting illusion that makes the burden of mortality a little easier to bear.
Horror, terror, fear, panic: these are the emotions which drive wedges between us, split us off from the crowd, and make us alone. It is paradoxical that feelings and emotions we associate with the "mob instinct" should do this, but crowds are lonely places to be, we're told, a fellowship with no love in it. The melodies of the horror tale are simple and repetitive, and they are melodies of disestablishment and disintegration ... but another paradox is that the ritual outletting of these emotions seems to bring things back to a more stable and constructive state again. Ask any psychiatrist what his patient is doing when he lies there on the couch and talks about what keeps him awake and what he sees in his dreams. What do you see when you turn out the light? the Beatles asked; their answer: I can’t tell you, but I know that it’s mine.
