People may praise the talent of a painter capable of realistically portraying a scene and dismiss as artistically worthless the efforts of abstract expressionists, but obviously an exact replica of the scene depicted is not the only thing people appreciate in a painting, for otherwise photography would have entirely displaced painting as an art form. The argument proceeds by ['appealing to an aesthetic principle to defend the tastes that people have', "appealing to a historical fact to support a claim about people's artistic preferences", 'explaining a historical fact in terms of the artistic preferences of people', 'considering historical context to defend the artistic preferences of people']
