Earnest lessons about a world
that doesn’t see him.
what does this mean?

Explanation:

What i think this means is that Ernest is learning about a world that doesn't exist.

How i got this was-

Lessons basically means learn, so we know Ernest is learning about something.

If a world doesn't see him, then it probably doesn't exist.

So it means that Ernest is learning about a world that doesn't exist.
