Sculpture is the art of the intelligence.

It is a mistake for a sculptor or a painter to speak or write very often about his job. It releases tension needed for his work.

A sculptor is a person who is interested in the shape of things a poet in words a musician by sounds.

The sculptor produces the beautiful statue by chipping away such parts of the marble block as are not needed - it is a process of elimination.

My interest in architecture has always been sculptural. Most of my photography is of architecture.

Architecture is inhabited sculpture.

Painting sculpture and architecture are finished but the art habit continues.

So what we have tried to do in our later buildings is to try to be completely consistent as a painter is consistent or as a sculptor is consistent. Architecture also must be very consistent.

At a certain point I just put the building and the art impulse together. I decided that building was a legitimate way to make sculpture.

Urs Fischer specializes in making jaws drop. Cutting giant holes in gallery walls digging a crater in Gavin Brown's gallery floor in 2007 creating amazing hyperrealist wallpaper for a group show at Tony Shafrazi: It all percolates with uncanny destructiveness operatic uncontrollability and barbaric sculptural power.

All of Koons's best art - the encased vacuum cleaners the stainless-steel Rabbit (the late-twentieth century's signature work of Simulationist sculpture) the amazing gleaming Balloon Dog and the cast-iron re-creation of a Civil War mortar exhibited last month at the Armory - has simultaneously flaunted extreme realism idealism and fantasy.

The best artist has that thought alone Which is contained within the marble shell The sculptor's hand can only break the spell To free the figures slumbering in the stone.

Photography suits the temper of this age - of active bodies and minds. It is a perfect medium for one whose mind is teeming with ideas imagery for a prolific worker who would be slowed down by painting or sculpting for one who sees quickly and acts decisively accurately.
