I think this song is describing what it is to be a musician (or perhaps more accuratly a lyricist). In trying to explain/understand/clarify things to people (the listeners), they are like scientists. In trying to show/display things to people (perhaps things they already know but can't put into words), they are like journalists. In trying to heal people with their music and words, they are pharmacists. But in trying to do all this for others, they lose themselves (but for GbV at least, thats ok, as the closing lines would indicate).
