Art v. craft

On the art blog suite101.com, Mary Rayme writes:
"Art is a work that transcends its humble materials to create an original statement or expression in a meaningful and enduring way. Crafts CAN transcend their humble materials as well to become art but it takes an experienced and determined crafter to do this. The elegant and humble quilts of Gee's Bend transcend their craft origins to become modern masterpieces of color and shape. Enjoy looking at these magnificent examples of great art being created out of great necessity."

My sculpture professor in college defined the distinction between art and craft in simpler terms:
"A craftsmen weeps over his mistakes. An artist celebrates them."

Art provides for more of a dialogue between the creator and the creation, where the artist responds to what the work says to him. Craft is a one-way conversation in which the crafter imposes his will on the work, beats it into submission, knows before he begins what the final product will look like and does not deviate.
A fine piece of craftsmanship can be beautiful but is is less likely to be original. Developing into a craftsman requires repetition of the same process time and again.
Art is riskier. Art follows a less-trodden path. It is at least as likely to fail as succeed. But it has greater potential.
The greatest work combines the practiced skill of the craftsman to an original work. The artist who can do that is the true master.
