Questions, always questions. Sort of the Socrates of ballet.
Balanchine the teacher, teaching everyone who might be willing, by challenging them, his dancers, his audience, his musicians, maybe even his stagehands, and - not least - himself! Everything since "just footnotes to Plato" including among some pretty impressive footnotes, Fred and Merce? Maybe that strains the analogy a bit. But yeah, the Socrates of ballet.
