Since it's related to my entry for this ff, I'm going to ask this and see if I can't get some feedback maybe.
Would you say having a soul and having a sense of self would be one in the same? If an omnipotent being was tearing from itself qualities that would define life and the things which reside in it, do you think soul and self would be separate concepts?
Honestly, it matters only what is the philosophy they have, if they have none in particular, then what does their culture think? Generally, people tend to base their ideas and concepts on what they are brought up with. For example, I grew up with the principle that all adverts are malicious that give viruses, and therefore I don't fall/get roped in to adverts, although this applied more to Internet Adverts, so TV ones obviously have effect. Apologies for trailing off, but what I am trying to say is that, Self-conciousness(or being aware of self, or is sentient) is an idea formed in place of the Christian/religious idea of a soul. As humans we have only just began to accept that the brain is you. In truth, what makes us live, with the amount of interaction of we do with our bodies, if you don't mind a religious bend, asking what actually links us from the spirit world to the mortal world/our bodies. That is a great philosphical question. So in short, a soul would be considered a religious version of sentience. Animals are not sentience, they live and they know how to live, but sentience is knowing that we are alive and with that comes literature, science and lots of other things.
It becomes tricky when you apply this to an omnipotent being, because it depends what it is, is a human turned omnipotent? It depends on the canon and the character. But if applied to a human, or as a general rule a soul is a different way of saying self. Unless you mean self in meaning their body, in which in that case they would be different.
Sorry for delving in to Philosophy and such, I think this conversation would be better placed in the roleplay Chit-Chat thread
