the purpose

"Did you ever notice that all machines are made for some reasons?"
...
"They are built to make you laugh, like the mouse here, or to tell the time, like clocks, or to fill you with wonder, like the automaton. Maybe that's why a broken machine always makes me a little sad, because it istn't able to do what it was meant to do."
...
"Maybe it's the same with people."
...
"If you lose your purpose... it's like you're broken."

Maybe I'm losing it, or becoming uncertain of it, or I've never known it.
