The basic tool for the manipulation of reality is the manipulation of words. If you can control the meaning of words, you can control the people who must use the words.
I've always thought of music as something which gives the words their flight and their wings and the music often comes first, although sometimes I'll have a concept, a title idea, a lyric idea that I want to write and the lyric will come first.
Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author's phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.
