The entity is no longer necessary for art.
It is nothing but to deny molding in art（It is nothing but to negate shaping in art.）
Why do not arts need shaping?
Because it is not essential element in art.
We experience art through conceptual differences,
Shaping in art is merely a device that creates that difference,
There is not at all need that the device is the shape.
Even if you see contemporary art, that is clear.
The appearance of installation art has established that.
Installation art is a way of expressing the relationship between space and modeling clearly as art.
However, Art derivative originally denies the physical space architecture, gestalt, affirmes only infosphere architecture,gestalt．
Art derivative is an attempt to consolidate art into infosphere only.
So, how can we experience that art?
We experience art in a dimension different from the previous dimension through all devices that mediate infosphere and physical space.
We can not experience art as art anymore.
Art derivative has succeeded in newly defining that conceptual difference that be experienced only in infosphere after the art has ended.
The physical art is ended,
art derivative of infosphere was created.
