Artistic symbols as support of a biased imagination

Ian McEwan has indulged in macabre plots whose points of interest reside in the power of the imaginary over allegedly rational reality. In novels like Atonement, Enduring Love, On Chesil Beach and Amsterdam he points out how approaching the world scientifically can be as misleading as doing it in religious or literary ways. The target of my paper is to spot those common loci of fanaticism and narrowed perspectives which have constituted the origin of many tragedies. Such a conjured tragedy may be identified with a sluice facilitating the passage from postmodernism to post-postmodernism
