Loebel Lectures and Workshop, Michaelmas Term 2015, Lecture 1 of 3: Neurobiological materialism collides with the experience of being human
The 2015 Loebel Lectures in Psychiatry and Philosophy were delivered by Professor Steven E. Hyman, director of the Stanley Center for Psychiatric Research at the Broad Institute of MIT and Harvard as well as Harvard University Distinguished Service Professor of Stem Cell and Regenerative Biology. Both the lecture series and the one-day workshop proved popular and were well-attended. Continue reading
On Thursday 16th October, Professor Kenneth Kendler delivered his second (and final) Loebel Lecture, entitled ‘The dappled causal world for psychiatric disorders: implications for psychiatric nosology’. You can view it online here or listen here.
Whilst Kendler’s first lecture – summarised by Roger Crisp here – focused on empirical issues, the second lecture was more philosophical. Kendler’s key question in the second lecture could perhaps be formulated as: Given the complex aetiology of mental disorders, how can we best understand and explain how they arise? Continue reading
The Genetic Epidemiology of Psychiatric and Substance Abuse Disorders: Multiple Levels, Interactions and Causal Loops
What causes psychiatric disorders, such as depression or alcohol abuse disorders? It’s obvious that background and upbringing often play a significant role, as do life events, such as losing one’s spouse or one’s job. And we also know now that genetic propensities are important. But how do these different factors inter-relate with one another? For over three decades, these issues have been at the centre of the research of Oxford’s first Loebel Lecturer, Professor Kenneth Kendler.
Professor Kendler is one of the world’s leading, and most highly cited, psychiatric researchers. He uses a range of methods, including family studies, twin and adoption studies, and molecular genetics. He also has a serious interest in the philosophy of psychiatry. His first Loebel Lecture — The Genetic Epidemiology of Psychiatric and Substance Abuse Disorders: Multiple Levels, Interactions and Causal Loops – was presented at the Oxford Martin School on Wednesday 15 October 2014, and is now available on Youtube and as an MP3 audio file.

Is there anything wrong with seriously entertaining this possibility? Not according to the author of a research article published this month in Journal of Religion and Health. In ‘Schizophrenia or possession?’,1 M. Kemal Irmak notes that schizophrenia is a devastating chronic mental condition often characterised by auditory hallucinations. Since it is difficult to make sense of these hallucinations, Irmak invites us ‘to consider the possibility of a demonic world’ (p. 775). Demons, he tells us, are ‘intelligent and unseen creatures that occupy a parallel world to that of mankind’ (p. 775). They have an ‘ability to possess and take over the minds and bodies of humans’ (p. 775), in which case ‘[d]emonic possession can manifest with a range of bizarre behaviors which could be interpreted as a number of different psychotic disorders’ (p. 775). The lessons for schizophrenia that Irmak draws from these observations are worth quoting in full:
As seen above, there exist similarities between the clinical symptoms of schizophrenia and demonic possession. Common symptoms in schizophrenia and demonic possession such as hallucinations and delusions may be a result of the fact that demons in the vicinity of the brain may form the symptoms of schizophrenia. Delusions of schizophrenia such as “My feelings and movements are controlled by others in a certain way” and “They put thoughts in my head that are not mine” may be thoughts that stem from the effects of demons on the brain. In schizophrenia, the hallucination may be an auditory input also derived from demons, and the patient may hear these inputs not audible to the observer. The hallucination in schizophrenia may therefore be an illusion—a false interpretation of a real sensory image formed by demons. This input seems to be construed by the patient as “bad things,” reflecting the operation of the nervous system on the poorly structured sensory input to form an acceptable percept. On the other hand, auditory hallucinations expressed as voices arguing with one another and talking to the patient in the third person may be a result of the presence of more than one demon in the body. (p. 776)
Irmak concludes that ‘it is time for medical professions to consider the possibility of demonic possession in the etiology of schizophrenia’ and that ‘it would be useful for medical professions to work together with faith healers to deﬁne better treatment pathways for schizophrenia’ (p. 776).
