Allan has worked for
many years on issues concerning mental health in eighteenth-century
writing, and particularly on the paradoxes and dilemmas of expressing
the experience of insanity within a period where diagnosis and treatment
could be both strict and random. His book, The Madhouse of Language:
Writing and Reading Madness in the Eighteenth Century (Routledge 1991)
examined these problems in the context of the social understanding
of language, both the language of the medical world and the language
of the so-called insane. More recently he has published (with Michelle
Faubert) Cultural Constructions of Madness in Eighteenth-Century Writing:
Representing the Insane (Palgrave 2005), which looks at literary and
visual representation of madness, or rather its misrepresentation
as part of a sane cultural or literary agenda. He has also edited
two collections of primary source material: Voices of Madness: Four
Pamphlets, 1683-1796 (Sutton 1997), which consists of four first-hand
accounts of the experience of being diagnosed as insane, and Patterns
of Madness in the Eighteenth Century: A Reader (Liverpool University
Press, 1998), which attempts to reflect the dialogue, or lack of it,
between writing by patients, or sufferers, and writing by medical
practitioners. His first book, based on his PhD thesis, was Boswell's
Creative Gloom: A Study of Imagery and Melancholy in the Writings
of James Boswell (Macmillan 1981), which discusses the paradox, recently
explored by Stephen Fry in his television programmes on Bipolar Disorder,
which links depression and creativity. He has spoken widely in Europe
and North America on aspects of his research.
