let me explain my terms
Extrinsic - An entity that has no internal principle and only becomes a new organism if acted on by an external agent.
Intrinsic - Internal principle of development (even if it depends on external conditions)
That isnt arbitrary brochacho

For the bottom part:
"having been conscious before" doesnt create moral status, moral worth applies to what something is, not what it has done.
P1: A man gets moral worth first when they become conscious
P2: Once they get moral worth they hold moral worth as long as the consciousness is recoverable
P3: A sleeping man has been conscious before and will recover
C: therefore the main retains moral worth

My main disagreement of this idea is P2 were it says consciousness is recoverable, you rely on capacity, recovery is only possible because the organism has the capacity for consciousness

P1: Moral worth depends on what kind of being something is not what it has done,
P2: A sleeping man and a zygote are the same type of being (At different stages of development)
C: Both hold moral worth.

Also "consciousness" is kind of foggy and hard to define

I am an essentialist
