Duchamp's great ambition was a very, very bold one.

It wasn't how to be a better artist, it was how to redefine the question

of what is it to be an artist.

He himself said in an interview that probably his greatest contribution, among many, to

the art of that century was the idea of the “readymade.”

A readymade work of art is something that Duchamp came up with in the teens, nineteen-teens.

And it was the idea that literally he could go to a store, choose an item, or maybe a

couple of items, and put them together, set it up in his studio, and call it a work of art.

This means that all of these notions that had gone for centuries, with the idea of an

all of these ideas associated with the beauty of a creation or with the suddenness of inspiration

are gone.

He, of course, was a painter when he started out.

First making impressionist pictures.

Then after Picasso led the way with Cubism, he made a variety of cubist paintings.

After he had been painting for about a decade, he decided, "You know, what's the point if

I'm one more very good or even excellent painter?

I'm not changing the world."

He bought a bicycle wheel and a kitchen stool, put them together, the wheel on top of the

stool, and kept it in his studio.

And from time to time, he would rotate the wheel.

One of the first readymades he made when he got to New York, where he was encountering

snow, was a work that he called "In Advance of the Broken Arm."

Oftentimes, the readymades had a title that was part of the work of art.

Bought it at a hardware store on the Upper West Side, took it to his studio, hung it up.

That was a readymade.

People, what should I say, tend to romanticize quite a bit the meaning.

What's the choice behind the wheel and the stool?

Is it sedentary and motion?

Is it round and round?

You can go on and on, and it brings out some really, kind of almost like parodies of what

art historians or critics might say.

But Duchamp maintained that it wasn't a matter of aesthetics and that it really was a matter

of the artist's brain.

And when he said that this was one of his greatest contributions, if not his greatest,

to the art of the century, I think what he was going for was the idea that all of this

took away the artist's or the viewer's retina as the most important thing.

And Duchamp called painting “retinal art,” and it was sort of like it was all about what

you would see with brush stroke and color.

Duchamp is trying to say retinal is substituting a lot for just dumbness.

Almost like religion is the opiate of the people.

Let's get away from that and let's get some ideas going.

This one is called "Why Not Sneeze, Rose Sélavy?"

Its title is a question.

Rose Sélavy was his pseudonym, his female alter ego name.

Totally puzzling question, "Why not sneeze?"

What we've got is a birdcage with some marble sugar cubes, a cuttlefish bone, and a little

thermometer—put together all of these store bought items, put together in a collage of objects.

When you see readymades from place to place in various museums, I think almost virtually

none of them, just a very few, maybe a handful, survived from the teens themselves

or the early '20s.

And thereafter, what you're seeing most everywhere else are re-editions of them that he made

in the '40s, '50s, or '60s.

The '50s and '60s were a time that he actually made them anew, in part because this is after

a couple of decades of relative non-celebrity, his art became of great interest to young artists again.

People like Jasper Johns, Robert Rauschenberg became fascinated by the model of an artist

who was not just concerned with craft and with the idea of hard work, but who just liked

the idea that an idea could be a work of visual art.

With pop art, with minimal art, and with what we now have come to call conceptual art in

the 1960s, all of this depended, to an immense degree, on the precedent of Duchamp in the

teens, having said to the world, "What matters for a work of art is what's going on

the choices that are being made, the decision that an artist makes.

Then he declares, or she declares, something to be a work of art, as an idea, as a concept.

And that's all that it needs, in fact, to be a work of art."

And it's amazing.

When I go on tours through these galleries, with visitors, they're looking at all kinds

of abstract, pretty difficult-to-decipher paintings on canvas

and they're taking it really well.

When we come to here, still 100 years later, invariably I get “why is that art?”

And I think that's one of the great tributes to Duchamp having succeeded at what he was

setting out to do.

He got people to question what otherwise is something that they just take for granted

without a second thought.
