well what Robbin pointed out in his comment on Sol Lewitt is still true.
We have ended up in a conceptual morass that makes critics and academics happy, but leaves artists on the ledge (and it's a long fall).
If we spit out the requirements of the conceptualist we find ourselves in open ground, unending and with a vast horison.
Stupid to think we have spent so much time on this paltry issue. Sad to think 30 yrs past before we found spme freedom.
