@bigstew,
Bigstew, you seem to be making three separate claims: (1) that pleasure/pain have intrinsic value/disvalue; (2) that pleasure/pain supply motivation; and (3) that pleasure/pain are moral properties. I think most people are willing to grant you (1) and (2). It's (3) that you have failed to explain, as I continue to bring to your attention. Your topic is titled "moral realism" not "value realism."
You have yet to provide a reasoned defense to these criticisms:
First, value or disvalue does not on its own make something moral or immoral. As you well know, food, water, shelter, education, friends, safety, material resources, political liberty, virtue, and so on, are all things people value. If you're going to arbitrarily label pleasure or pain as moral properties you need to explain why these other intrinsic values are not moral also. You can't simply reduce these other goods to pleasure and pain. We're dealing with "qualitatively different" types of values in these cases.
Second, there are countless forms of moral experience that are not primarily characterized by pleasure or pain. If someone is genuinely honest, it isn't that they are telling the truth to feel good; they are telling the truth for the "simple reason" that it is the right thing to do under the circumstances (i.e., because they value the truth or authenticity). Or take temperance: Are you sincerely willing to claim that someone refrains from pleasure for the sake of pleasure? That's nonsensical. A person is temperate in order to further their other "goals"; those other "values."
Third, you have yet to account for our moral language of praise and blame. Nobody calls another person good because they produced a pleasurable experience for themselves or others. We praise others for their moral character and fine actions: Because they do things for the right reasons or because their intentions are noble. Wouldn't you be suspicious of someone who only respected you for the sake of your pleasure or for the sake of the pleasure they could secure for themselves? To use your own example, if someone is set on fire, it isn't the pain that is morally at stake, it's the "life" and intrinsic worth of the "person." Pleasure and pain can never aspire to be anything more than the bodily consequences of our moral psychology.
