" In periods such as the early Middle Ages, which in general were free from social conflict, there is not, as a rule, any radical antagonism between artistic intention and technique; the art forms and the technique are employed harmoniously and say the same thing in different ways, the one factor being no more rational or irrational than the other. But in times like the Gothic age, when the whole of culture was rent by antagonisms, it often happens that the spiritual and material elements in art speak different languages and, as in the present case, the technique appears rational but the artistic aims irrational.
