"How is he made? Oftentimes bitter, sometimes sweet, seldom even wide-awake, architectural criticism of "the modern" wholly lacks inspiration or any qualification because it lacks the appreciation that is love: the flame essential to profound understanding. Only as criticism is the fruit of such experience will it ever be able to truly appraise anything. Else the spirit of true criticism is lacking. The spirit is love and love alone can understand. So art criticism is sour and superficial today because it would seem to know all about everything but understand nothing."
