How is consciousness without a brain any more possible than a square circle?

Well it is more possible in the sense that the former is not logically impossible.

The definition of consciousness need not include its requirement of a physical substrate (a brain.) While the definitions of squares and circles include mutually contradictory requirements; A square has exactly four sides, no more, no less, and a circle has exactly infinity.

But that is about as far as it goes; logically possible.
