As all historians know, the past is a great darkness, and filled with echoes.

Love blurs your vision; but after it recedes, you can see more clearly than ever.

There's a difference between describing and evoking something. You can describe something and be quite clinical about it. To evoke it, you call it up in the reader. That's what writers do when they're good.

Hope drives us to invent new fixes for old messes, which in turn create ever more dangerous messes. Hope elects the politician with the biggest empty promise; and as any stockbroker or lottery seller knows, most of us will take a slim hope over prudent and predictable frugality.
