New member - excuse me for butting in, but you're on one of my favorite topics and I hope you don't mind my 2 cents.

Among the aspects of science already mentioned is that it (real science) operates within a very restricted set of rules of evidence, which makes the study of art and/or morality difficult, but not impossible, imo.

Science is limited to mutually agreeable definitions of reality and most of the definitions involved in these two topics are fuzzy from the scientific perspective. Doesn't make them wrong - just makes "scientific analysis" difficult.
