Time, our most precious resource, even if we don't know what it is.

Time is no doubt now one of our most precious commodities. We're inclined to buy our time back at whatever we determine to be a reasonable rate. Yet, it was St Augustine who said in his Confessions:

"What then is time? If no one asks me, I know: If I wish to explain it to one who asketh, I know not"

But even if we cannot understand exactly what it is, it has a distinct impact on how we view the world and our place in it.
