The strongest interpretation of the statement
Imagine someone whose understanding of life contains only one apparent path: follow the family occupation, accept an inherited belief, repeat a familiar response, or obey an established expectation.
That person can make decisions within the path. What they have not yet considered is whether the path itself is negotiable.
Curiosity introduces a different kind of question:
Why this? What else exists? Could this be otherwise? Why do I want what I want?
The important transition is not simply from ignorance to information. It is from treating a framework as the entirety of reality to recognizing it as something that can be examined.
On that interpretation, your statement means:
Curiosity begins the discovery that what has been given to us is not necessarily all that is possible for us.
This is its strongest philosophical content. Freedom concerns not only selecting among presented options, but also participating in the discovery and evaluation of the options themselves.
Consider the difference between choosing a response from an existing menu and asking whether the menu is complete. Curiosity can operate before the obvious moment of decision, altering what the eventual decision is about.
