To speak of beauty is to enter another and more exalted realm-a realm sufficiently apart from our everyday concerns as to be mentioned only with a certain hesitation. People who are always in praise and pursuit of the beautiful are an embarrassment, like people who make a constant display of their religious faith. Somehow, we feel such things should be kept for our exalted moments, and not paraded in company, or allowed to spill out over dinner.

There is a crucial distinction to be made between innovation and originality. The second, unlike the first, can never break with what preceded it: to be original, an artist must also belong to the tradition from which he departs. To put it another way, he must violate the expectations of his audience, but he must also, in countless ways, uphold and endorse them.

Styles may change, details may come and go, but the broad demands of aesthetic judgement are permanent.

Were we to aim in every case at the kind of supreme beauty exemplified by Sta Maria della Salute, we should end with aesthetic overload. The clamorous masterpieces, jostling for attention side by side, would lose their distinctiveness, and the beauty of each of them would be at war with the beauty of the rest.
