Schoenberg and serial music

Schoenberg being a lover of order in music (he used traditional forms) created a set of rules that composers could use. Also he was influenced by the socialist belief in absolute economic and social equality and gave the notes absolute equality or "socialism in music". Also I know this is annoying but Schoenberg's opera was published as Moses und Aron Schoenberg changed it because Moses und Aaron had 13 letters a number he feared deeply. (not kidding)
