Lyric discussion by DavidB 

I'm with the 'Nietzsche' interpretation. I'm not sure that Nietzsche himself ever actually used the phrase 'homo superior', but it is a term that anyone would associate with him. As for the Arthur C. Clarke connection, obviously Bowie had some interest in science fiction, but Clarke himself was probably drawing on Nietzschean themes, so the two interpretations are not mutually exclusive. Nothing to do with homosexuality, of course.

Well, wouldn't the Superman be a Homo Superior? At least to us at least
