Yes, we know more than ever before, and it's a wonder that we get to inhabit a world full of driverless cars and 3D printers. But that doesn't mean that we know any more about the essential things in life - love, faith, death - and it would be dangerous to assume we did. The only thing that gets us through sometimes is a proper, humbled sense that we don't have a clue, we can't be sure what's going to happen next and life will always be much larger than our ideas of it.
