“You may not see it now,” said the Princess of Pure Reason, looking knowingly at Milo’s puzzled face, “but whatever we learn has a purpose and whatever we do affects everything and everyone else, if even in the tiniest way.”

“You’ll find,” he remarked gently, “that the only thing you can do easily is be wrong, and that’s hardly worth the effort.”

“Have you ever heard the wonderful silence just before the dawn?” she inquired. “Or the quiet and calm just as a storm ends? Or perhaps you know the silence when you haven’t the answer to a question you’ve been asked, or the hush of a country road at night, or the expectant pause in a roomful of people when someone is just about to speak, or, most beautiful of all, the moment after the door closes and you’re all alone in the whole house? Each one is different, you know, and all very beautiful, if you listen carefully.”

“How can you see something that isn’t there?” yawned the Humbug, who wasn’t fully awake yet.
“Sometimes it’s much simpler than seeing things that are,” he said. “For instance, if something is there, you can only see it with your eyes open, but if it isn’t there, you can see it just as well with your eyes closed. That’s why imaginary things are often easier to see than real ones.”

“That was all many years ago,” she continued; “but they never appointed a new Which, and that explains why today people use as many words as they can and think themselves very wise for doing so. For always remember that while it is wrong to use too few, it is often far worse to use too many.”

Milo nibbled carefully at the letter and discovered that it was quite sweet and delicious — just the way you’d expect an A to taste.

“I knew you’d like it,” laughed the letter man, popping two G’s and an R into his mouth and letting the juice drip down his chin. “A’s are one of our most popular letters. All of them aren’t that good,” he confided in a low voice. “Take the Z, for instance — very dry and sawdusty. And the X? Why, it tastes like a trunkful of stale air. That’s why people hardly ever use them. But most of the others are quite tasty. Try some more.”

He gave Milo an I, which was icy and refreshing, and Tock a crisp, crunchy C.

“I never knew words could be so confusing,” Milo said to Tock as he bent down to scratch the dog’s ear.

“Only when you use a lot to say a little,” answered Tock.

Milo thought this was quite the wisest thing he’d heard all day.
