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.

This quote refers to the art of sculpting, which is the process of carving a figure or object out of a hard material like marble. The sculptor starts with a block of marble, and then carefully chips away the parts of the block that are not part of the design. This process of removing pieces is called a process of elimination, because each chip eliminates a piece of marble that doesn’t belong in the sculpture.
