The swallow that hibernates underwater is a creature called yearning.

There__ a voice that says: "So what?"It__ not my voice, it__ probably not yours, but it makes itself heard in the arenas of public opinion, querulous and smug and fortified by just a little knowledge, which as always is a dangerous thing. "So what if a bunch of species go extinct?" It says. "Extinction is a natural process. Darwin himself said so, didn__ he? Extinction is the complement of evolution, making room for new species to evolve. There have always been extinctions. So why worry about these extinctions currently being caused by humanity?" And there has always been a pilot light burning in your furnace. So why worry when your house is on fire?

Of course anyone who truly loves books buys more of them than he or she can hope to read in one fleeting lifetime. A good book, resting unopened in its slot on a shelf, full of majestic potentiality, is the most comforting sort of intellectual wallpaper.

Alternatively, anyone who favors Intelligent Design in lieu of evolution might pause to wonder why God devoted so much of His intelligence to designing malarial parasites.
