In order to function in a modern society a museum should combine the two purposes that justify it. It ought to be both modern and democratic, which means that it should not only supply additional information on its exhibits, but also carefully select the kind of information supplied. Selection should been made on the assumption that an exhibit is a cultural product which possesses in itself an aesthetic value; also, that it has been created by an individual, therefore it includes a phsychological value; and last, since its creator is a social being, the exhibit has, in addition, a sociological value. Only when all of these conditions occur, do we get the fullest possible consideration of an approach to the cultural product.
