  • The twelfth chapter of Turner's De Morbis Cutaneis. A Treatise of Diseases incident to the Skin London 1714 Turner appears to have used the terms fancy and imagination synonymously and interchangeably in his writings on the maternal imagination. According to his preface Turner received an imprimatur from the College of Physicians of London for this work in 1712, and had it published two years later by Rebecca Bonwicke. Hereafter, this work will be referred to as ‘Spots and Marks’.

  • One case, purportedly from ancient times, involved a child of ‘Ethiopian Complexion’ who was delivered to white parents. Physicians and philosophers explained the child's colour as the result of the mother's ‘Intent viewing’ of a picture of an Ethiopian that hung in her bedchamber throughout her pregnancy. Many authors, including Daniel Turner, attributed this case to Hippocrates. M. D. Reeve, in a recent work covering much of the Renaissance literature on ‘Conceptions’ Proceedings of the Cambridge Philosophical Society, No. 215 1989 93 93 n.s., No. 35 has shown that this case did not originate with Hippocrates; rather its misattribution to the father of medicine can be traced to De viribus imaginationis, the 1608 writing of Thomas Fienus. I am indebted to Amal Abou-Aly for this reference. James Blondel, Turner's opponent also argued that no such case existed in the Hippocratic Corpus. Yet, a similar case which Reeve described as the ‘Andromeda effect’ appeared in Aethiopica, a work of Heliodorus. Discussion of the Biblical passage will follow.

Ballantine's comprehensive search of the medical and philosophical literature from antiquity through the early twentieth century for reference to this maternal power remains the most complete bibliographic source to date.

  • The widespread appeal of popular medical writings such as Robert Burton's Anatomy of Melancholy and Aristotle's Masterpiece may have helped perpetuate a belief in the power of the mother's imagination.

Francesco Maria Nigrisoli also argued against the common belief in the power of the maternal imagination in his Considerazioni Intorno alla generazione de' viventi (Ferrara, 1712), p. 5.

Blondel's use of ‘vulgar’ in the sense of the common people is similar to Thomas Browne's discussion of such errors in his Pseudodoxia Epidemica: or, Enquiries into Vulgar and Common Errors London 1646 Browne did not, however, include the power of the mother's imagination as an erroneous belief.

  • Blondel's preference of a strict scriptural interpretation rather than supposition is indicative of the sustained influence of Frederick Spanheim, his Leiden Professor of Theology. See Sassen's F.L.R. The Intellectual Climate in Leiden in Boerhaave's Time Boerhaave and his Times Lindeboom G. Leiden 1970 2 3 in Blondel's appreciation of his instructor is identifiable by the dedication of his medical thesis, Disputatio Medica Inauguralis de Crisibus (Leiden, 1692), to Spanheim.

According to the biographical entry in Ollivier and Raige-Delorme Dezeimeris's Dictionnaire Historique de la Médecine (Paris, 1828), I, p. 418, Blondel was well versed in the Dead Languages, particularly Hebrew, and he wrote a large number of theological works. Reeve (footnote 5), 97, claimed some aspects of Blondel's account were ‘more accurate than any I have found in the commentaries’. Samuel Kottek, in his ‘La Force de L'Imagination chez les femmes enceintes. ‘A propos d'un texte biblique apporté par J.

  • In a later publication, Turner detailed several hundred cases which he attended as a London surgical practitioner roughly between 1694 and 1711. Turner's view of London surgical practice as a corrupt trade, dominated by untrained and unskilled pretenders is documented in his Apologia Chyurgica: A Vindication of the Noble Art of Surgery London 1695 and The Present State of Chyrurgery (London, 1703). I am producing a biography of Turner as part of my dissertation.
  • Perusal of surgical texts from this period suggests that surgical practitioners were employed to treat skin disorders and venereal disease, incise and dress boils and swellings, reduce fractured bones and dislocated joints, ‘couch’ cataracts, extract teeth, repair ruptures and fistulae, amputate limbs, and ‘cut’ for bladder stone. Turner claimed that a surgeon was ‘the most proper Person to be consulted’ for disorders requiring ‘Manual Operation’ in the preface to his Syphilis. A practical Dissertation on the Venereal Disease London 1724 Attempts by officials of the Barber-Surgeons Company of London to expand their realm of care legally has been documented in many traditional surgical histories, for example, Cecil Wall, The History of the Surgeons Company, 1745–1800 (London, 1937), pp. 25–6.

  • The lack of references to this chapter before 1727 is corroborated by Turner's view that until 1727 his work ‘never gave offence, at least that I have heard’.

  • Standard biographical entries state that he was born in Paris in 1665, and that his father, a French legal counsellor, desired a similar career for his son.

Rees, The Cyclopedia or Universal Dictionary of Arts, Sciences, and Literature (London, 1819), IV, section BLO; and Dictionary of National Biography. Although I found few records of his medical education in Leiden, he was presumably exposed to the same teaching as his classmate, Herman Boerhaave.

The Huguenots continued to gain numerical and political strength in early-eighteenth-century London. Since the 1689 Toleration Act of William and Mary, Huguenot assemblages as organized factions of protestant dissent received increasing support from the English. See R. D. Gywnn, Huguenot Heritage: The History and Contribution of the Huguenots in Britain (London, 1985). Blondel was ‘Certified’ as a member of the French Church on Threadneedle Street in 1700, and resided in one of the large Huguenot areas of ‘Northeastern’ London.

  • Turner's use of ‘Power’ of Imagination in ‘Spots and Marks’ and The Force in his 1730 work implied, as will be discussed, an immaterial impetus, whereas the implications of Blondel's use of the terms ‘Strength’ and ‘Power’ remains uncertain. Such terms were consistent with his adherence to ‘Newtonian’ doctrine, but given Blondel's displayed talent as both a scholar and wit, he may have used these terms as a parody on Turner's titles. As such, it supports Simon Schaffer's claim that a Newtonian language was often used ‘for specific pugnacious purposes’. See Newtonianism Companion to the History of Modern Science Olby R.

Turner also drew upon Fienus's account, implicating the role of imagination in ‘producing almost every kind of disease’, namely, squinting, stuttering, small pox, and the plague (p. 110).

See his ‘From Mechanism to Vitalism in Eighteenth-Century English Physiology’, Journal of the History of Biology, 7 (1974), 200, footnote 72. Opposition to mechanism in both early- and late-eighteenth-century contexts needs to be more fully explored.
  • Turner . A Defence 133 – 133 . Turner did not mention this reference to the attractive force of the magnet in 1714, but added it to his 1729 treatise. Over this timespan, the study of attraction had gained the status of an independent field of study in natural philosophy. Nicholas Robinson, perhaps London's most staunch Newtonian physician, claimed, in 1725, that one problem unsolved by attractive particles was the influence of the mind on the body.

  • Joseph M. Levine, in his reappraisal of the debate between the Ancients and the Moderns beyond that of R. F. Jones, qualified the eighteenth-century supporters of the ancients as selectors, borrowing only the passages they found most useful from ancient doctrine and ignoring the rest. Moreover, he argued that the essence of the battle was a question of history, i.e., the ‘meaning and Use of the past’ and the ‘method of apprehending it’. See Ancients and Moderns Reconsidered Eighteenth Century Studies 1981 15 78 78 84 The ancients/moderns question was brought to public attention in London literature of late 1726 with the publication of Gulliver's Travels. The work added support to those who preferred the ancients for, as G. S. Rousseau argued, it illustrated the modern's ‘craze over absurd scientific effort’. See Rousseau's ‘Science’, in The Context of English Literature: The Eighteenth Century, edited by P. Rogers (London, 1978), p. 161.

  • Joseph Needham made this claim in Limiting Factors in the Advancement of Science as Observed in the History of Embryology Yale Journal of Biology and Medicine 1935 8 15 15 Although Blondel specified reason as one component of his argument and Turner gathered empirical detail, a lack of a clear distinction between the two protagonists supports Andrew Wear's recent claim that rationalist/empiricist divisions more likely represent an historical categorization than an historical fact. See A. Wear, ‘Medical Practice in late Seventeenth- and Early Eighteenth-Century England: Continuity and Change’, in The Medical Revolution of the Seventeenth Century, edited by R. French and A. Wear (Cambridge, 1989), p. 304. Indeed, Turner praised London surgeon Richard Blundell for having ‘Declined Mathematical Argumentation … [and] invoke[d], rather a rational Empiricism’. See the dedication in Turner's Syphilis (London, 1717).

Cambridge 1990 138 164 in Adrian Wilson (footnote 38), 7, 8, also discusses the uses of pamphlets as ‘appeals for public support’. Hillel Schwartz described a contemporary appeal for a wide audience by religious groups in his The French Prophets: The History of a Millenarian Group in Eighteenth-Century England (Berkeley, California, 1980).
  • N. D. Jewson first discussed the public's role in determining the care and medicines they received in Medical Knowledge and the Patronage System in Eighteenth-Century England Sociology 1974 8 369 385 Roy Porter has also argued that part of a physician's success at this time depended upon ‘public favour’, and has documented how physician's arguments were addressed to the public. See ‘Laymen, Doctors, and Medical Knowledge in the Eighteenth Century: the Evidence of the Gentleman's Magazine’ in Patients and Practitioners, edited by R. Porter (Cambridge, 1985), p. 311; and D. Porter and R. Porter, Patient's Progress: Doctor and Doctoring in Eighteenth-Century England (Cambridge, 1989), p. 102. Marina Benjamin has also discussed the role of the patient as judge in ‘Medicine, Morality and the Politics of Berkeley's Tar-Water’ in The Medical Enlightenment of the Eighteenth Century, edited by A. Cunningham and R. French (Cambridge, 1990), especially pp. 176–80.
  • Medical practitioners regularly confronted ‘quack’ remedies in attempts to dispel any mystery about ‘miraculous’ curative powers that the remedies were claimed to have held. See for example, Doherty Francis The Anodyne Necklace: A Quack Remedy and its Promotion Medical History 1990 34 268 293

The evidence which ovists Albrecht von Haller, Charles Bonnet, and Lazzaro Spallanzani gathered showed that the female was chiefly responsible for in utero development. It was used, by some, in support of the impressionists’ argument.
  • For example, it has been claimed that William Hunter questioned each pregnant woman in a ‘large’ London lying-in-hospital whether anything had ‘specially affected’ her mind during pregnancy, and he recorded the answers. After many year of collecting this information, Hunter had not found ‘one instance’ suggesting a relation between the woman's answer and any ‘abnormal structure’ on the child when delivered. Brown John Notes and Observations on Maternal Impressions Glasgow 1887–1888 3 3 Hunter scholars, however, have not uncovered any evidence that such experimentation occurred.

  • In addition to the works of Blackman, King, Park and Daston, and Rousseau already cited, Blondel and Turner also appear in the chapter entitled ‘Rabbits and Quacks’ of Harvey Graham's (pseud.) Eternal Eve Altrincham 1950 345 346 Numerous midwifery texts of the nineteenth century also referred to the debate, see for example Michael Ryan, Manual of Midwifery (Burlington, 1835), pp. 64–73. In another context, see P.-G. Bouce's ‘Imagination, Pregnant Women, and Monsters in Eighteenth Century England and France’, in Sexual Underworlds of the Enlightenment, edited by G. Rousseau and R. Porter (Manchester, 1988), especially pp. 89–94. Barbara Stafford discusses this debate in her chapter on ‘Markings’ in Body Criticism: Imaging the Unseen in Enlightenment Art and Medicine (Cambridge, Mass., 1991). Finally, Ian Stevenson delivered a lecture entitled ‘The Mother's Possible Influence in Birthmarks in cases of the Reincarnation Type' on 22 January 1989 at ‘Parapsychology: A State-of-the-Art Conference’ in New York. One goal of my ongoing work on Turner is to re-examine this dispute in respect of his later expressed concern for ‘disorders peculiar to women’.
  • See, for example Lowenthal L.J.A. Daniel Turner and ‘De Morbis Cutaneis’ Archives of Dermatology 1962 85 517 523 R. J. Mann, ‘Daniel Turner, the First British Dermatologist’, Mayo Clinical Proceedings, 51 (1976), 62–6, and even the more historically grounded writing of P. J. Hare perpetuated Turner's unfavourable reputation in his Our Credulous Countryman (Edinburgh, 1967). One important exception is the short article by Alan Lyell, ‘Daniel Turner (1667–1740) LRCP London (1711) M. D. Honorary, Yale (1723) Surgeon, Physician and Pioneer Dermatologist; The Man Seen in the Pages of His Book of the Skin’, International Journal of Dermatology, 21 (1982), 162–70. Here (p. 168), Lyell explained Turner's reliance on authority more as a reverence for earlier works than as a blind acceptance of their word.
