The idea behind structuralism is that there are things we may not know but we can learn how they are related to each other. This has been used by science since it existed and can be extended to a few other studies — linguistics and mythology — but certainly not to everything. The great speculative structures are made to be broken. There is not one of them that can hope to last more than a few decades, or at most a century or two.

For mile after mile the same melodic phrase rose up in my memory. I simply couldn’t get free of it. Each time it had a new fascination for me. Initially imprecise in outline, it seemed to become more and more intricately woven, as if to conceal from the listener how eventually it would end. This weaving and re-weaving became so complicated that one wondered how it could possibly be unravelled; and then suddenly one note would resolve the whole problem, and the solution would seem yet more audacious than the procedures which had preceded, called for, and made possible its arrival; when it was heard, all that had gone before took on a new meaning, and the quest, which had seemed arbitrary, was seen to have prepared the way for this undreamed-of solution.
