I'd certainly say there is a spectrum of varying human consciousness from fetus>baby>young child>child
I would say so on a more minute to minute basis. Awake, asleep, drunk, daydreaming, hypnosis......
Does it vary within each category?
Lets say it does. Perhaps a brain damaged person in a coma has less consciousness. Or perhaps someone who is just asleep has less consciousness. Whats your interesting moral question?
I seem to have forgotten
Not only that but you (or I) have varying levels of consciousness minute to minute. We conflate many different states of mind and call them all 'conscious' whereas they differ massively.
