The beginning of the end

 From The Bride and the Bachelor (Tomkins).  

Some disciples of Merce Cunningham "arrived at a sort of non-dance aesthetic that could dispense with such rudimentary requirements as dance training and physical technique. Cunningham himself has never been willing to dispense with technique, and as a result he is looked upon by some of his former disciples with a respect that is slightly tinged with condescension."  

Here the logical consequence (reductio ad absurdum) of an avant-garde practice is to condescend to the founder of such a practice.
