The article's definition of consciousness is precise, but it's not what people are referring to in most cases where the word "consciousness" is used. Of course, a word can have multiple definitions. But colloquially, when people say consciousness, we usually mean the thing that goes away when we sleep or are anesthetized. I don't think there's a much better way to define that. The contrast between the wakeful and non-wakeful state as oneself experiences from the inside is precisely what defines consciousness in the colloquial sense. It seems to be a self-defining concept because I can't even define what "experiences" means without thinking about the wakeful/non-wakeful contrast phenomena that is consciousness, and "experiences" was supposed to be a part of the definition of "consciousness" one sentence ago.
