Re: set of a set etc.

The description is what I would call formal, not conceptual. "My cat"
and the set of my cat {My cat} are different conceptually. My cat likes
milk. The "set of my cat" does not, yet the two denotations are closely
related. What is the conceptual relationship between the two?

Your cat is a member of the set of your cat. The set of your cat is not a member of your cat.

Sets are collections. A collection is distinct from the objects therein (usually). Put a ring in a box. The box contains the ring; the box and the ring are not the same thing.
