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

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

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.

After a few months in my parents' basement, I took an apartment near the state university, where I discovered both crystal methamphetamine and conceptual art. Either one of these things are dangerous, but in combination they have the potential to destroy entire civilizations.

Great art - or good art - is when you look at it, experience it and it stays in your mind. I don't think conceptual art and traditional art are all that different.

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