Formal art is essentially rational.

The most interesting characteristic of the cube is that it is relatively uninteresting. Compared to any other three-dimensional form, the cube lacks any aggressive force, implies no motion, and is least emotive. Therefore, it is the best form to use as a basic unit for any more elaborate function, the grammatical device from which the work may proceed.

In conceptual art the idea or concept is the most important aspect of the work

You shouldn't be a prisoner of your own ideas.

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.

All of the significant art of today stems from Conceptual art. This includes the art of installation, political, feminist and socially directed art.

Banal ideas cannot be rescued by beautiful execution.
