Aesthetics and Art Theory (A Dutton paperback)

Harold Osborne (Aesthetics and Art Theory) identified three basic ways in which we can think about works of art. In the simplest sense, a work of art has certain physical properties. It is made of a material (e.g., wood, marble, clay, paint on canvas, ink on paper) which possesses texture, contains shapes, occupies a portion of space, reflects certain colors, and is apprehended over time.
