Unlike the marks of a painting, the photo seems to organize its 'opinions' in relation to the world; even when the photographs have clearly been manipulated, the 'opinions' seem to have all the more force, with the suggested 'participation of the world' articulating that 'opinion' as a difference.
Joseph KosuthWhen objects are presented within the context of art (and until recently objects always have been used) they are as eligible for aesthetic consideration as are any objects in the world, and an aesthetic consideration of an object existing in the realm of art means that the object's existence or functioning in an art context is irrelevant to the aesthetic judgment.
