I'm not sure how to define these words.

Question

1) moral authorities
2) systematic empirical research
3) scientific research

Answer 1

http://en.wiktionary.org/wiki/moral_authority

http://en.wikipedia.org/wiki/Empirical_research

http://en.wikipedia.org/wiki/Research#Scientific_research

Answer 2

For moral authority, is the definition a very good one even from Wikitionary? Maybe the definition is the same on other sites. I think it's better if I have the non-Wikipedia sites.

Answer 3

You can do the same thing I did.

Google each of those terms.
