The timing of this exhibition couldn’t have been better, for the ancient dialectic of madness and art has become a major contemporary issue. It increasingly seems that madness alone can save contemporary art from its success, from its tendency to reduce itself to the most common terms to win acceptance and recognition. Here is the one true “outsider art,“ as it in fact was originally designated. Although it is generally regarded more as a symptom of psychosis than high art (a dubious accolade that may be a comedown for it), much “insider art” endorsed by museums and collectors pales in comparison.
