As those who have seen jurassic park will know, this means a tiny disturbance in one place, can cause a major change in another. A butterfly flapping its wings can cause rain in central park, new york. The trouble is, it is not repeatable. The next time the butterfly flaps its wings, a host of other things will be different, which will also influence the weather. That is why weather forecasts are so unreliable.
Melville had to fight, fight against the existing world, against his own very self. Only he would never quite put the knife in the heart of his paradisal ideal. Somehow, somewhere, somewhen, love should be a fulfillment, and life should be a thing of bliss. That was his fixed ideal. Fata morgana. That was the pin he tortured himself on, like a pinned-down butterfly.
Now i am in the garden at the back . . . a very preserve of butterflies as i remember it, with a high fence, and a gate . . . where the fruit clusters on the trees, riper and richer than fruit has ever been since, in any other garden, and where my mother gathers some in a basket while i stand by, bolting furtive gooseberries, and trying to look unnerved.
