“If there wasn’t anything to find out, it would be dull. Even trying to find out and not finding out is just as interesting as trying to find out and finding out; and I don’t know but more so.”
It’s impossible to know everything, and dangerous to think you do. But to remain curious, there’s the thing.
And if wanting to know as much about everything as you can doesn’t make the world a more interesting place, it might make you more interesting to the world.
