One picks one's way about through the glass and aluminum doors, the receptionists' smiles, the lunches with too much alcohol, the openings with more, the mobs of people desperately trying to define good taste in such loud voices one can hardly hear oneself giggle, while the shebang is lit by flashes and flares through the paint-stained window, glimmers under the police-locked door, or, if one is taking a rare walk outside that day, by a light suffusing the whole sky, complex as the northern aurora.
The popular distinction between 'constructive' and 'destructive' criticism is a sentimentality: the mind too weak to perceive in what respects the bad fails is not strong enough to appreciate in what the good succeeds. To be without discrimination is to be unable to praise. The critic who lets you know that he always looks for something to like in works he discusses is not telling you anything about the works or about art; he is saying 'see what a nice person I am.
...indeed it is very true that, just as the finest air in the world is vulgarized beyond all bearing once the public has taken to hum it and the street organs to play it, so the work of art that has appealed to the sham connoisseurs, that is admired by the uncritical, that is not content to rouse the enthusiasm of only a chosen few, becomes for this very reason, in the eyes of the elect, a thing polluted, commonplace, almost repulsive.
