The Essential Features of the Modern Revolt

The ballet contains and illustrates many of the essential features of the modern revolt: the overt hostility to inherited form; the fascination with primitivism and indeed with anything that contradicts the notion of civilization; the emphasis on vitalism as opposed to rationalism; the perception of existence as continuous flux and a series of relations, not as constants and absolutes; the psychological introspection accompanying the rebellion against social convention.

I had no idea ballet was so subversive.
