> Can there be consciousness without content? E.g. can I just be conscious of being conscious?

Being conscious of being conscious means that there is content. You are conscious of something.

It’s a bit like a Gödel statement that quotes itself, that is a statement about itself. It doesn’t mean that it has no content.

Thinking isn’t consciousness. Consciousness doesn’t require thinking, it only requires perception. The perception of a process of perception within the same mind might constitute consciousness.
