Minimalism wasn't a real idea - it ended before it started.

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

A blind man can make art if what is in his mind can be passed to another mind in some tangible form.

The narrative of serial art works more like music than like literature.

In my case, I used the elements of these simple forms - square, cube, line and color - to produce logical systems. Most of these systems were finite; that is, they were complete using all possible variations. This kept them simple.

Just as the development of earth art and installation art stemmed from the idea of taking art out of the galleries, the basis of my involvement with public art is a continuation of wall drawings.

Unless you're involved with thinking about what you're doing, you end up doing the same thing over and over, and that becomes tedious and, in the end, defeating.

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

Artists of many diverse types began using simple forms to their own ends.

Artists teach critics what to think. Critics repeat what the artists teach them.

Buying books was a way anyone could acquire a work of art for very little.

Conceptual art became the liberating idea that gave the art of the next 40 years its real impetus.

During the '70s I was interested in words and meaning as a way of making art.

Every generation renews itself in its own way; there's always a reaction against whatever is standard.

I was not interested in irony; I wanted to emphasize the primacy of the idea in making art.

Minimal art went nowhere.

The artist is seen like a producer of commodities, like a factory that turns our refrigerators.

The other great development has been in photography, but that too was influenced by Conceptual art.

The thinking of John Cage derived from Duchamp and Dada. I was not interested in that.

When artists make art, they shouldn't question whether it is permissible to do one thing or another.
