There 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 DamasioIt's very interesting to think about the distinction with mind, which I just made in very general terms, but it can be made more profound when we think that there are many species, many creatures on earth that are very likely to have a mind, but are very unlikely to have a consciousness in the sense that you and I have.
Antonio DamasioBut whether we want to do it because we want to have people to have a different idea of who we are or not, we do it naturally. So the way we construct our narrative is different from the way we constructed it a year ago. The difference is maybe very small or it may be huge.
Antonio DamasioWe do not merely perceive objects and hold thoughts in our minds: all our perceptions and thought processes are felt. All have a distinctive component that announces an unequivocal link between images and the existence of life in our organism.
Antonio DamasioI 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.
