@Reconstructo,
Austin had an interesting take on this...
He broke "speech acts" into two categories. One, "performative" utterances, such as saying "you are fired!" or "You are now married" change something (in these cases, relationships) in the world. The other, "constantive" utterances, work in terms of truth and falsity.
A very substantial problem in the Ordinary Language Philosophical tradition was whether the kind of statements you are mentioning, such as "Murder is Wrong" or "Mary is good" are performative or constantive.
In one sense, we are making a statement about the world. When I say "Murder is Wrong!", am I stating something metaphysically true, and just conveying the information? or am I
making something true by uttering it in this way?

Does this mean that I am not conveying anything substantial, informative or specific when I say the night sky is beautiful?
