“The fantastic in literature doesn't exist as a challenge to what is probable, but only there where it can be increased to a challenge of reason itself: the fantastic in literature consists, when all has been said, essentially in showing the world as opaque, as inaccessible to reason on principle. This happens when Piranesi in his imagined prisons depicts a world peopled by other beings than those for which it was created. ("On the Fantastic in Literature")”

“As has already been noted, fantastic literature developed at precisely the moment when genuine belief in the supernatural was on the wane, and when the sources provided by folklore could safely be used as literary material. It is almost a necessity, for the writer as well as for the reader of fantastic literature, that he or she should not believe in the literal truth of the beings and objects described, although the preferred mode of literary expression is a naive realism. Authors of fantastic literature are, with a few exceptions, not out to convert, but to set down a narrative story endowed with the consistency and conviction of inner reality only during the time of the reading: a game, sometimes a highly serious game, with anxiety and fright, horror and terror.”

“The great impact of Hellenistic culture was, however, no in natural science, but in the more Plato-inspired imaginative literature. The modern novel has its origins in the ultra-heroic and fantastic literature of the Hellenistic world intellectually centered in Alexandria. The life of Alexander the Great was itself one of the prime genres of Hellenistic romanticized literature, and remained so into the sixteenth century.”

“Fantastic literature has been especially prominent in times of unrest, when the older values have been overthrown to make way for the new; it has often accompanied or predicted change, and served to shake up rational Complacency, challenging reason and reminding man of his darker nature. Its popularity has had its ups and downs, and it has always been the preserve of a small literary minority. As a natural challenger of classical values, it is rarely part of a culture's literary mainstream, expressing the spirit of the age; but it is an important dissenting voice, a reminder of the vast mysteries of existence, sometimes truly metaphysical in scope, but more often merely riddling.”

“The fantastic postulates that there are forces in the outside world, and in our own natures, which we can neither know nor control, and these forces may even constitute the essence of our existence, beneath the comforting rational surface. The fantastic is, moreover, a product of human imagination, perhaps even an excess of imagination. It arises when laws thought to be absolute are transcended, in the borderland between life and death, the animate and the inanimate, the self and the world; it arises when the real turns into the unreal, and the solid presence into vision, dream or hallucination. The fantastic is the unexpected occurrence, the startling novelty which goes contrary to all our expectations of what is possible. The ego multiplies and splits, time and space are distorted.”

“Life itself has lost its plane reality: it is projected, not along the old fixed points, but along the dynamic coordinates of Einstein, of revolution. In this new projection, the best-known formulas and objects become displaced, fantastic, familiar-unfamiliar. This is why it is so logical for literature today to be drawn to the fantastic plot, or to the amalgam of reality and fantasy. ("The New Russian Prose")”
