The thing about Proust is his combination of the utmost sensibility with the utmost tenacity. He searches out these butterfly shades to the last grain. He is as tough as catgut and as evanescent as a butterfly's bloom.
And besides, look at elder flowers and bluebells-they are a sign that pure creation takes place - even the butterfly. But humanity never gets beyond the caterpillar stage -it rots in the chrysalis, it never will have wings.It is anti-creation, like monkeys and baboons.
