When Kevin Kelly interviewed me about The Information for Wired, he asked me to define the word, and I was unprepared. I did some hemming and hawing (which he mercifully omitted). I see it continues to trouble him. Others have asked me the same question, and I continue to hem and haw. You might think I would have it figured out by now.
The problem of definition runs as a a minor thread throughout my book. The very idea that a word has a definition is surprisingly new—barely 400 years old. You might think it is obvious, but it is not. People managed to use words for millennia without worrying too much. John Locke felt it necessary to explain in his Essay Concerning Human Understanding:
Definition being nothing but making another understand by Words, what Idea the term defined stands for.
In the very first English dictionary, Robert Cawdrey’s Table Alphabeticall in 1604, we see that defining words is not so easy. I quote a few of my favorite Cawdrey definitions (in their entirety):
crocodile, [kind of] beast.
vapor, moisture, ayre, hote breath, or reaking.
theologie, divinitie, the science of living blessedly for ever.

And I quote Arcadia all over again in The Information: the unexpected, wise response of Septimus to Thomasina’s grief over the ancient destruction of the Great Library of Alexandria (“All the lost plays of the Athenians!”):
