And the situations are purely Dick. His “plots” are like nothing else in SF. If Dick writes a time-travel story, say, it will have a twist on it that makes it sui generis. Quite typically, the central gee-whiz marvel will not be centered, but will come at you obliquely, in the course, for instance, of a political election.

And any relation between Dick and a nuts-and-bolts SF writer is a pure coincidence. In my more sanguine moments, I concede that he probably knows what happens when you plug in a lamp and turn it on, but beyond that there is little evidence of either technology or science. His science, such as it is, is all engaged in the technology of the soul, with a smattering of abnormal psychology.

So far I have perhaps emphasized his oddities at the expense of his merits. What keeps you reading Dick? Well, for one thing, the strangeness, as I said, but within it there is always the atmosphere of striving, of men desperately trying to get some necessary job done, or striving at least to understand what is striking at them. A large percentage of Dick’s heroes are tortured men; Dick is expert at the machinery of despair.

And another beauty is the desolations. When Dick gives you a desolation, say after the bomb, it is a desolation unique of its kind. There is one such in this book. But amid the desolation you often find another of Dick’s characteristic touches, the little animals.

The little animals are frequently mutants, or small robots who have taken on life. They are unexplained, simply noted by another character in passing. And what are they doing? They are striving, too. A freezing sparrow hugs a rag around itself, a mutant rat plans a construction, “peering and planning.” This sense of the ongoing busy-ness of life, however doomed, of a landscape in which every element has its own life, is trying to live, is typically and profoundly Dick.
