"Det har vært min tese at post-modernismen er en logisk videreføring av modernitetens bestrebelser. Den analytiske og livsfjerne rasjonalitet som utfolder seg i det moderne prosjekt tømmer virkeligheten for værensfylde og spalter dens enhet i separate gyldighetsområder, for så til sist å servere det hele som usammenhengende fragmenter. Dette er post-modernismens utgangsposisjon, der så vel verden som bevisstheten er pulverisert til particularia. Hvilket innebærer at det ikke lenger går forpliktelseslinjer, verken til nåtiden eller til fremtiden"

"Conceptual art is not necessarily logical. The logic of a piece or series of pieces is a device that is used at times only to be ruined. Logic may be used to camouflage the real intent of the artist, to lull the viewer into the belief that he understands the work, or to infer a paradoxical situation (such as logic vs illogic).* The ideas need not be complex. Most ideas that are successful are ludicrously simple. Successful ideas generally have the appearance of simplicity because they seem inevitable. In terms of idea the artist is free even to surprise himself. Ideas are discovered by intuition.

*Some ideas are logical in conception and illogical perceptually."

"In conceptual art the idea or concept is the most important aspect of the work.* When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art. This kind of art is not theoretical or illustrative of theories; it is intuitive, it is involved with all types of mental processes and it is purposeless. It is usually free from the dependence of the skill of the artist as craftsman. It is the objective of the artist who is concerned with conceptual art to make his work mentally interesting to the spectator, and therefore usually he would want it to become emotionally dry. There is no reason to suppose, however, that the conceptual artist is out to bore the viewer. It is only the expectation of an emotional kick, to which one conditioned to expressionist art is accustomed, that would deter the viewer from perceiving this art.

*In other forms of art the concept may be changed in the process of execution"
