I figure morality as a topic is popular enough and important enough and related-to-rationality enough to deserve its own thread.
Questions, comments, rants, links, whatever are all welcome. If you're like me you've probably been aching to share your ten paragraph take on meta-ethics or whatever for about three uncountable eons now. Here's your chance.
I recommend reading Wikipedia's article on meta-ethics before jumping into the fray, if only to get familiar with the standard terminology. The standard terminology is often abused. This makes some people sad. Please don't make those people sad.
Love - in increase in her utility causes an increase in your utility.
Hate - in increase in her utility causes a decrease in your utility.
Indifference - a change in her utility has no influence on your utility.
Love = good.
Hate = evil.
Indifference = how almost everyone feels towards almost everyone.
What are you trying to do with these definitions? The first three do a reasonable job of providing some explanation of what love means on a slightly simpler level than most people understand it.
However, the "love=good, hate=evil" can't really be used like that. I don't really see what you're trying to say with that.
Also, I'd argue that love has more to do with signalling than your definition seems to imply.
