One lesson the arts teach is that there can be more than one answer to a question and more than one solution to a problem; variability of outcome is okay. […] The arts teach children that their personal signature is important and that answers to questions and solutions to problems need not be identical. There is, in the arts, more than one interpretation to a musical score, more than one way to describe a painting or a sculpture, more than one appropriate form for a dance performance, more than one meaning for a poetic rendering of a person or a situation. In the arts diversity and variability are made central. That is one lesson that education can learn from the arts.

Variant: "The arts teach children that problems can have more than one solution; questions can have more than one answer. If they do anything, the arts embrace diversity of outcome."
