“The works of the Impressionists, as much as those of any medieval craftsman or renaissance Humanist, are related to a world view, a context of interdependent beliefs and ideas about what is good and bad, true and false, the nature of existence and the means for investigating it. There are no ‘value vacuums’ in human history, no ‘intermediary periods’, only periods which are more or less unified, more or less amenable to the procedures, and temperaments, of historians.”
