"When I was younger I thought my knowledge would increase with years, that it was steadily expanding like the universe. A constantly widening area of certainty that correspondingly displaced and diminished the reach of uncertainty. I was really very optimistic. With the passage of time I must admit that I know roughly as much as then, perhaps even slightly less, and with nothing like the same certainty. My so-called experiences are not the same as knowledge. It is more like, how shall I put it, a kind of echo chamber in which the little I know rings hollow and inadequate. A growing void around a scant knowledge that rattles foolishly like the dried-up kernel in a walnut. My experiences are experiences of ignorance, its boundlessness, and I will never discover how much I still don't know, and how much is something I believed."
