According to Oscar Wilde, 'the primary aim of the critic is to see the object as in itself it really is not'. Through a series of close and often unusual readings, this book endeavours to develop Wilde's remark into a detailed and creative theory of reading. Or perhaps that should be misreading: for, as this experimental work of criticism negotiates its way among the works of a number of late-nineteenth-century writers, particularly Robert Louis Stevenson and Wilde himself, Tearle uncovers some of the ways in which we as readers are prone to hallucinations while reading about, of all things, the experience of hallucination. Focusing in detail on a series of neologisms from writing of the period, such as 'handconscience', 'figmentary', and 'aftersense', and moving between a number of disciplines including literature, criticism, science, psychoanalysis, and even linguistics, Bewilderments of Vision endeavours to answer a number of questions, ranging from the urgent to the downright bizarre: What is the link between hallucination and social conscience in writing of the late-nineteenth century? Is there such a thing as textual hallucination? Why does the author of this book see a 'snake' that is not there when he 'reads' Jekyll and Hyde?.
