I think it's reasonable to say that even thought, in all likelihood, we have slightly different experiences of reality, they are similar enough to us not to clash. In other words, I'm not, it's very unlikely, in fact, let's say impossible, for you to say the situation in which you and I are in right now, relative to the machinery that is capturing this.
Antonio DamasioThere are ways in which you can make that distinction objective to a certain degree. For example, by looking at responses that could be generated in the brain to exactly the same stimulus and there could be differences there.
Antonio DamasioImagine, for example, birds. When they look out at the world, they have a sense that they are alive. If they are in pain, they can do something about it. If they have hunger or thirst, they can satisfy that. It's this basic feeling that there is life ticking away inside of you.
Antonio DamasioConsciousness, much like our feelings, is based on a representation of the body and how it changes when reacting to certain stimuli. Self-image would be unthinkable without this representation.
