Which line is deeper?

[Nicknameless]

Which line in Tom Sawyer do you find deeper?

"And what you say about his company

Is what you say about society.

or

"He knows changes aren’t permanent,

But change is."

[daslied]

I'd go for the first one, since you're asking for a choice to be made.

The second one is just a variation of "The only thing constant is change."

"And what you say about his company

The first.
