What’s her argument?
Graslie is a curiosity correspondent – she helps people be curious. Her argument is that people are generally curious, but to pursue this curiosity, the feeling of curiosity must exist first. That is, the curiosity must be aroused by something.
Quote that supports your contention:
“You can only be curios about something when you know it exists.”
We aren’t very curious about many things, simply because we do not know about them. For example, if I didn’t know there was a dog (Sideways) buried on Georgia Tech’s campus, I would never have gone looking for the grave.
