Given the professional necessity to convince patients of a doctor’s authority, even, if necessary, by trickery, it comes as no surprise that the line between medicine and quackery is often blurred. And in literary portrayals of doctors, we can often sense the anxiety of patients who realise that a doctor’s air of authority comes from his specialised, eloquent speech and his medical paraphernalia – professional trappings that are as easily adopted by charlatans and tricksters as by genuine practitioners of the medical arts. The famously cynical writer Abū Ḥayyān al-Tawḥīdī (d. 1023) portrays one doctor speaking at a patient’s bedside in learned-sounding but completely nonsensical language. ‘I see that you are not keeping anything but a diet above what is necessary and below what is not necessary,’ he says, for example (ed. Iḥsān 1993, vol. 15, 45). This meaningless phrase echoes medical language, which, in its struggle for precision, often sounds confusingly repetitive. For example, Ibn al-Nafīs, a thirteenth-century physician famous for describing the pulmonary circulation of the blood, writes something similar in his commentary on the first Hippocratic Aphorism, which reads, ‘Life is short, the Art long, opportunity fleeting, experiment treacherous, judgement difficult. The physician must be ready, not only to do his duty himself, but also to secure the co-operation of the patient, of the attendants and of externals’ (ed. Jones 2005, 98-99). In part of his commentary on this wide-ranging aphorism, Ibn al-Nafīs writes, ‘So it is necessary that you confine yourself to the remainder of an action less than which is necessary or is not necessary to do and is not necessary not to do’ (Ibn al-Nafīs, Sharḥ Fuṣūl Abuqrāṭ, Oxford, Bodleian Library, MS Pocock 294. f. 7a.). Al-Tawḥīdī can be excused for mocking such language, and the mental tongue-twister that it may unintentionally present...
