This is my first post on the Christianity thread and since I'm new, I haven't had time read 250 something of discussion. However, the consciousness is a topic that interests me greatly and is also a topic which I believe should be treated separately to religion.
The dictionary definition of consciousness given by evo is purely a psychological definition. There are no references that I can see in regards to the consciousness in a physical sense.
This is because no one knows what consciousness truly is (physically speaking)
Some believe that consciousness is directly related and/or part of the soul. Some also believe that the soul can exist completely independent without a biological body.
I like to think of it (maybe simplistic but works for me) like a car and driver. The car is useless without the driver but destroying all the cars won't destroy the drivers (Unless you're in it at the time but that's a physical limitation that the soul isn't subjected to.), the drivers will find something else to do.
The only point of possible disagreement (I don't know for sure) is whether consciousness can be destroyed or not. Matter cannot be created or destroyed, but can be converted into other types of matter. If it can, I'll corss that bridge when I come to it.
