According to C.S. Lewis:

To be stories at all they must be series of events: but it must be understood that this series—this plot, as we call it—is only really a net whereby to catch something else. The real theme may be, and perhaps usually is, something that has no sequence in it, something other than a process and much more like a state or quality. Giantship, otherness, the desolation of space, are examples that have crossed our path…
In life and art both, as it seems to me, we are always trying to catch in our net of successive moments something that is not successive. Whether in real life there is any doctor who can teach us how to do it, so that at last either the meshes will become fine enough to hold the bird, or we be so changed that we can throw our nets away and follow the bird to its own country, is not a question for this essay. But I think it is sometimes done—or very, very nearly done—in stories. I believe the effort to be well worth making.
