Modern life seems set up so that we can avoid loneliness at all costs, but maybe it's worthwhile to face it occasionally. The further we push aloneness away, the less are we able to cope with it, and the more terrifying it gets. Some philosophers believe that loneliness is the only true feeling there is. We live orphaned on a tiny rock in the immense vastness of space, with no hint of even the simplest form of life anywhere around us for billions upon billions of miles, alone beyond all imagining. We live locked in our own heads and can never entirely know the experience of another person. Even if we're surrounded by family and friends, we journey into death completely alone.
