'Oliver Sacks is a neurologist, a man of humane eloquence, and a genuine communicator' Observer 'Sacks writes, basically, adventure stories, accounts of voyages into the unexplained territory of the brain. In doing so, he reveals a landscape far more complex and strange than anything we could infer from our daily interactions' Sunday Times 'Sacks is above all a clinician, and writes with compassion and clarity ... The result is a sort of humane discourse on the fragility of our minds, of the bodies that give rise to them, and of the world they create for us' Daily Telegraph 'In measured prose with a blessed lack of jargon, Sacks explores the ingenuity with which individuals cope with bizarre neurological conditions ... humane, empathic, he is the doctor you would want' Independent 'Oliver Sacks has become the world's best-known neurologist. His case studies of broken minds offer brilliant insight into the mysteries of consciousness' Guardian 'Sacks is at his most engaging when he brings the ostensibly strange into the realm of normality ... This is where Sacks triumphs. Not just in the clarity with which he teaches us about the obscure phenomology of the human brain, but in the light his writings casts on even our most ordinary experiences.' Daily Telegraph 'The king of pop-neurology reveals how almost all of us have hallucinations' GQ 'It's a feat to bring any specialty in medicine vividly to life, and to do so without relinquishing the sensitivity and empathy that characterise the best doctors is something that few achieve. Oliver Sacks has managed it throughout his career ... Affable, affectionate, respectful and smart, Sacks could be the David Attenborough of the human mind.' Independent on Sunday 'An enthralling, often guiltily comic insight into the pecularities the brain can conjure.' Irish Examiner 'Oliver Sacks is a graceful, lucid and elegant prose stylist. Though perhaps above all, he is the witty, warm, humble and deeply compassionate explorer of how our brains influence our world ... fascinating.' Lady 'Hallucinations is an absorbing study of an exotic subject ... Hallucinatory literature is either transgressive or presented as a search for enlightenment. This new volume sits elegantly between the two extremes and is more rewarding than either - a continuing investigation into what makes us human.' Literary Review 'The greatest living ethnographer of those fascinating tribes qho live on the outer and still largely unchartered shores of the land of Mind-and-Brain.' Observer 'A very human insight into what happens when our brains go awry.' Psychologies 'Sacks writes in the the great tradition of literary doctors. He is humane, relaxed and amused, and loved a good anecdote.' Spectator 'Startling and intriguing' Sunday Times 'No more enlightening science book has appeared this year ... Miss this at your peril.' Sunday Times Science Book of the Year 'A superb synthesis of the literature on these arresting, disturbing and sometimes terrifying phenomena, and a profound work of humanity.' TLS 'Fascinating' The TImes 'Wide-ranging, compassionate and ultimately revelatory ... Hallucinations is the keystone of the amazing edifice that is this remarkable thinker's oeuvre.' Will Self, Guardian
