I must be being slow and missing something. I understand how this would
work if every course were called the same, but that's not quite what's

"If art is the vehicle for the expresion of an artist's feelings it may
well be that an artist will deliberately seek to produce ugly or
rebarbative, challenging or even disgusting works. (Many among
contemporary artists succeed; one imagines it is considerably easier
