What's with all the Socratic action here ... ? Let me just answer your question with a question ...When my friend and I look at an apple, do we see the same exact color?
Is saying I'm alive and conscious redundant?
1. If I am your friend, we do not.
a. if you are literally saying this, then to be redundant here means that in every case that you say "I'm alive" means that you are conscious. Is that what you mean?
One possible case is that you are in a dreamless sleep and utter "I'm alive" - arguably you would then be alive, but not conscious and therefore free of redundancy.
b. if you mean saying of you that you are alive implies you are conscious, then we can point to any case when you are non-dead but unconscious.
c. if you are dead and conscious, I want to know about it immediately
in terms of how do we know we are conscious - why would it occur to you, if you weren't? perhaps a p zombie would verbalize things about consciousness and "try" to convince others - but it would never occur to them, because nothing ever occurs to a p zombie ...
