Our mistake, here as elsewhere, is to think that equality and diversity are irreconcilable. The common notion of equality is based on the image of the march. In a parade, really unequal beings are dressed alike, given guns of identical length, trained to hold them at the same angle, and ordered to keep in step with a fixed beat. There you have real equals assigned unequal roles in order that each may achieve his individual perfection in the whole. It is the choice image of fulfillment through function, and it comes very close to the heart of the Trinity.
Marriage is a hierarchical game played by co-equal persons.
Capon s illustration can be drawn out still further. It is a remarkable thing, I think, if you think about it, that you cannot really tell who is the better dancer when comparing an accomplished ballerina and a great male lead. No one can say. For they danced completely different roles and the roles required of them completely different things. All you know for sure is that, beautiful as Swan Lake was when they danced it together, it would have been grotesque had they attempted to switch roles, and Fonteyn attempted to lift Nureyev over her head.
