Dictionaries tend to define the moral as the good.It is hard to believe that anyone can grow up not hearing the word "good" used a lot, unless they were raised by wolves

The problem isn't that I don't know what it means.

What "moral" means or what "good" means/?

The problem is that it means many different things and I don't know which of those you mean by it.

No, that isn't the problem. It has one basic meaning, but there are a lot of different theories about it. Elsewhere you say that utilitarianism renders objective morality meaningful. A theory of X cannot render X meaningful, but it can render X plausible.

I have moral sentiments (empathy, sense of justice, indignation, etc.), so I'm not amoral. And I am not particularly high time-preference, so I'm not a hedonist.

But you theorise that you only act on them(and that nobody ever acts but) toincrea se your pleasure.

If you mean preferences that everyone else shares, sure, but there's no stipulation in my definitions that other people can't share the preferences.

I don't see the point in stipulating that preferences can't be shared. People who believe they can be just have to find another word. Nothing is proven.

You may be making the classic of error of taking "subjective" to mean "believed by a subject"

It'd be a "classic error" to assume you meant one definition of subjective rather than another, when you haven't supplied one yourself?

I've quoted the dictionary derfinition, and that's what I mean.

"existing in the mind; belonging to the thinking subject rather than to the object of thought ( opposed to objective). 2. pertaining to or characteristic of an individual; personal; individual: a subjective evaluation. 3. placing excessive emphasis on one's own moods, attitudes, opinions, etc.; unduly egocentric"

This is about the eight time in this discussion that I've thought that I can't imagine what you think language even is.

I think language is public, I think (genuine) disagreements about meaning can be resolved with dictionaries, and I think you shouldn't assume someone is using idiosyncratic definitions unless they give you good reason.
