They define contemporary art as the work of artists who are living in the twenty-first century. Contemporary art mirrors contemporary culture and society, offering teachers, students, and general audiences a rich resource through which to consider current ideas and rethink the familiar. The work of contemporary artists is a dynamic combination of materials, methods, concepts, and subjects that challenge traditional boundaries and defy easy definition. Diverse and eclectic, contemporary art is distinguished by the very lack of a uniform organizing principle, ideology, or -ism. In a globally influenced, culturally diverse, and technologically advancing world, contemporary artists give voice to the varied and changing cultural landscape of identities, values, and beliefs.
