What the work of art looks like isn't too important. It has to look like something if it has a physical form. No matter what form it may finally have it must begin with an idea. It is the process of conception and realization with which the artist is concerned.
Sol LeWitt[The artist's aim is] not to instruct the viewer, but to give him information... . The artist would follow his predetermined premise to its conclusion, avoiding subjectivity. Chance, taste, or unconsciously remembered forms would play no part in the outcome. The serial artist does not attempt to produce a beautiful or mysterious object but functions merely as a clerk cataloguing the results of his premise.
