Have you never felt down and simply decided to be upbeat instead and then were by choice alone? If not, try it now. Decide to be ecstatic and see if you can do it. Maybe you won't succeed in being ecstatic but you might notice some change in mood. Do it without any crutch, such as thinking about a beautiful sunset. Just focus on the decision alone and nothing else.Let's look at Damasio's treatment of "consciousness":
Damasio: Consciousness, 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. I think humans have developed a self-image mainly to establish a homeostatic organism. The brain constantly needs up-to-date information on the body's state to regulate all the processes that keep it alive. This is the only way an organism can survive in an ever changing environment. Emotions alone—without conscious feelings—would not be enough. Adults would be as helpless as babies if they suddenly lost their self-image.
Damasio's (and your) view strike me as deterministic. At the same time, you both subtly imply an actor who must have some free will in some sense.
To elaborate, I see some
basic problems with his description that are left unanswered in neurobiology and modern academic science generally.
Basic #1: He implies there is an actor but never addresses where or what that actor is. For example, he says,"...humans have developed...." Okay, where is that human who develops stuff precisely located? Note that you also imply such an actor when you say "we could simply choose." Well, where are you and how do you make
any choice?
Basic #2: What and where precisely is consciousness?
Basic #3: Where exactly are the "self-image" and "information" stored? Where is any memory stored for that matter?
