"Well, I don't know, 'cept when you think you know what you're thinking about, and when you wonder you just don't know anything." "Maybe you wonder when you don't know what to think," Katie suggested.
"Yes, maybe so.

There's more to wonder about than there is to think about, don't you think so, Aunt Kate ?" "I wonder," she laughed.
"You do wonder, don't you, Aunt Kate?
You wonder more than you think." She flashed him a keen, queer look.
"Worth," she asked, after another pause in which the mind of twenty-five and the mind of six were wondering in their respective fashions, "do you know anything about the underlying principles of life ?" "The what, Aunt Kate ?" "Underlying principles of life," she repeated grimly.
"Why no," he acknowledged, "I guess I never heard of them." "I never did either, till just lately.

I want to find out something about them.

Do you know, Worthie dear, I'd go a long way to find out something about them." "Where would you have to go, Aunt Kate?
Could you go in a boat ?" "No, I fear you couldn't go in a boat.

Trouble is," she murmured, more to herself than to him, "I don't know where you _would_ go." "Don't Papa know 'bout them ?" "I sometimes think he would like to learn." "Papa knows all there is to know 'bout guns and powders," defended Worth loyally.
"Yes, I know; but I don't believe guns and powders have any power to get you to these underlying principles of life." "Well, what _does_ get you there ?" demanded her companion of the practical sex.
She laughed.
