Outside theology and fantastic literature, few can doubt that the main features of our universe are its dearth of meaning and lack of discernible purpose. And yet, with bewildering optimism, we continue to assemble whatever scraps of information we can gather in scrolls and books and computer chips, on shelf after library shelf, whether material, virtual or otherwise, pathetically intent on lending the world a semblance of sense and order, while knowing perfectly well that, however much we'd like to believe the contrary, our pursuits are sadly doomed to failure.
