Episode 3/4 – October 1, 2025
Host: Chloé Rouillon, Xavier Mauduit
Guest: Léo Bernard, historien (Université d’Angers), auteur d’Hippocrate initié : courants ésotériques et holisme médical en France durant l’entre-deux-guerres
Overview
This episode explores the fascinating history and controversies surrounding alternative medicines in France—focusing on the period between the two World Wars (1920s–1940s). Through a lively exchange with historian Léo Bernard, it delves into the meaning of "holism" in medicine, the interplay between science and spirituality, and the wide spectrum of practices and beliefs that challenged (and sometimes intertwined with) mainstream medical science: naturism, vegetarianism, homéopathie, reflexology, esotericism, and more.
Key Discussion Points & Insights
1. Defining Medical Holism
[01:26–04:50]
- Holism is presented not merely as a loosely defined catch-all term but as a specific historiographical concept. It denotes a movement—mainly from the 1920s–40s—where physicians see the patient as a "whole" (body, mind, environment).
- This attitude arose partly as a response to the "excesses" of laboratory-based and analytical medicine, which focused on diseases as being caused by specific, external agents (microbes, viruses, bacteria).
Quote:
"Le holisme médical, c’est une attitude commune : concevoir l’individu comme un tout, aux aspects physiques et psychiques interconnectés, inscrit aussi dans un environnement spécifique."
— Léo Bernard [01:41]
- The term "holisme" itself is later, coined by historians, with contemporary practitioners often using phrases like "médecine synthétique" or "néo-hippocratique".
- Debate exists within the movement: for some, it’s about returning to an ancient "synthetic" medicine, for others, it’s a call for balanced coexistence with laboratory medicine.
2. Alternative Medicine as Historical Continuity
[04:03–05:55]
- Although holism as a movement is situated in the 20th century, holistic approaches (treating the whole person) echo ancient, medieval, and early modern practices.
- The "return to the views of the Ancients" is a recurring motif, often invoked to legitimize alternative medical strategies.
Quote:
"Les médecins de l’époque se revendiquent d’un héritage ancien, de revenir aux vues des Anciens."
— Léo Bernard [05:55]
3. The Influence of Spiritualism, Esotericism, and the Broader Cultural Context
[08:05–12:09]
- The discussion situates alternative medical practice in a broader intellectual reaction against reductionist scientism and materialism, citing figures like Camille Flammarion.
- Catholic spiritualism and esotericism (theosophy, occultism) both feed into holistic medical attitudes, sometimes complementing, sometimes clashing with each other.
Quote:
"Ce courant médical ne sort pas de nulle part. Il s’inscrit dans un contexte culturel plus global [...] il faut prendre en compte l’âme pour soigner aussi ses patients."
— Léo Bernard [10:17]
4. Vegetarianism and Naturism: Medical and Philosophical Roots
[13:38–20:51]
- Vegetarianism is not just diet, but often a moral, even spiritual stance (e.g., avoiding "animal suffering" as a source of impurity, referencing philosophers from Pythagoras to Gandhi).
- Naturism (initially) is a reform movement encompassing diet, hygiene, sunbathing, nudity, and a return to "natural" living. Over time, its meaning shifts more towards leisure and nudity.
- Paul Carton, a prominent French doctor, is cited as central to the medical/naturalist approach.
Quote:
"Le naturisme fait un carton."
— Chloé Rouillon [18:54]
"Carton, il est vraiment imprégné par ces courants-là [ésotériques]."
— Léo Bernard [20:51]
5. The Diversity and Ambiguity of Alternative Health Movements
[20:51–23:48]
- There’s significant overlap, but also tension, between rational/physical and spiritual/esoteric motivations—e.g., some vegetarians motivated by health, others by theosophy, some by both.
- Many practitioners are fully accredited doctors; alternative beliefs are not the preserve of quacks.
Quote:
"Ces mouvements-là ne sont pas dans un rejet absolu de tous les progrès de la médecine."
— Chloé Rouillon [12:09]
"On a affaire à des gens qui ont leur diplôme de médecine."
— Léo Bernard [25:13]
6. Biographical Trajectories and the Role of Personal Experience
[26:12–28:55]
- Biographies often feature a moment when conventional medicine was felt inadequate—sometimes spurred by the personal illness of the doctor (e.g., Paul Carton).
- Alternative methods offer empowering frameworks: illness results from unnatural lifestyle, so the patient can take control.
Quote:
"Ça fait porter la responsabilité de la maladie sur les épaules du patient. Mais il y a un échappatoire...celle de changer ses conditions de vie, changer son alimentation."
— Léo Bernard [28:05]
7. The Language of Universal Force and Vitalism
[29:00–33:42]
- Readings from figures like Gaston Durville evoke the idea of a "force vitale" or universal magnetic energy, central to both naturism and magnetism.
- The Durville family are prominent practitioners, founding sunbathing/naturist colonies (Physiopolis, Héliopolis), blending health, spirituality, and social reform.
Quote:
"Gaston Durville...est complètement imprégné par les considérations magnétiques, notamment cette idée qu’il existe un fluide universel..."
— Léo Bernard [29:56]
8. The Cyclical "Fashions" of Medical Alternative Practices: Homéopathie, Reflexology
[34:20–53:16]
- Homéopathie is described as having "effects of fashion": popularity surges, declines, then revives (notably in the 1920s, led by Léon Vanier).
- Homéopathie in France is both a philosophy and a science, based on "law of similars" and personalization. Later, typologies of patients are devised, sometimes using esoteric methods like biblical numerology (gématrie).
- Reflexology (réflexothérapie) emerges around 1910, positing that stimulating nerves can influence distant organs; acupuncture is reinterpreted as a form of reflexotherapy.
Quote:
"On peut qualifier ça d’effet de mode, mais en tout cas l’homéopathie revient...sur le devant de la scène."
— Léo Bernard [34:20]
"On cherche la connaissance du type...c’est perçu comme un savoir valide que d’aller le chercher dans la Bible ou dans d’autres textes anciens."
— Léo Bernard [41:23]
"L’acupuncture...est comprise à ce moment-là comme une forme de réflexothérapie."
— Léo Bernard [52:30]
9. Internal Debates, Dissensions, and the Relationship With Religion
[41:23–48:41]
- Alternative movements are not uniform—there are sharp debates, e.g. within homéopathie, between proponents of esotericism and those who prefer a "scientific" identity.
- Interactions with mainstream religion (Catholicism): sometimes a source of conflict (accusations of occultism), sometimes of synergy (spiritual healing).
Quote:
"Il y a une scission au sein du mouvement de l'homéopathie française...on va essayer de s’en démarquer en faisant la promotion d’une homéopathie scientifique et moderne."
— Léo Bernard [43:00]
10. The Proliferation of Publications and the Importance of Print Culture
[53:16–54:55]
- Despite a lack of access to private archives, the historian emphasizes the wealth of print sources: journals, monographs, reviews—testifying to the vibrancy of public debate and the accessibility of these ideas.
Quote:
"J’ai une masse de documentation complètement incroyable ... tous ces courants-là publient beaucoup."
— Léo Bernard [53:48]
11. The Historical Specificity and Legacy of the Interwar Period
[54:55–56:58]
- The "entre-deux-guerres" period is described as a unique moment, with lively hybridization and debate; WWII brings an abrupt stop, but the legacy persists into the later 20th century.
Quote:
"C’est un peu frustrant...ça monte, ça monte...et d’un coup, un arrêt des publications [avec la guerre]"
— Léo Bernard [55:13]
Memorable Moments & Quotes
-
On the wide range of medical practitioners:
"Un naturiste, homéopathe, réflexothérapeute, magnétiseur et pourquoi pas spécialiste de la théosophie, de l’occultisme ou de l’ésotérisme."
— Chloé Rouillon [00:09] -
On vegetarian morality:
"Les végétariens sont des gens qui associent la morale et la diététique. Ils ne mangent pas de viande car les animaux nous ressemblent trop et cela n’est pas bien de manger son semblable."
— Xavier Mauduit [00:56] -
On rational and spiritual co-existence:
"Il peut y avoir une cohabitation, bien sûr... les considérations spirituelles-là sont assez mal acceptées au sein de la société et que si on veut faire passer le message du végétarisme, il vaut mieux mettre de côté ces aspects-là..."
— Léo Bernard [21:40] -
On the resilience of alternative practices:
"Tout ce mouvement-là que vous avez étudié n’est pas en marge. Il y a des échos d’ailleurs. La plupart des médecins que vous évoquez vivent encore et certains jusqu’à les années 60-70."

Conclusion
This episode richly demonstrates that the history of alternative medicine in France is not a simple opposition to scientific modernity but a complex, dynamic space of negotiation and synthesis. Real doctors—some high-profile, others more marginal—bridged the worlds of science, diet, spirituality, and cultural reform. Whether their approaches "scratched or tickled" the boundaries of science, they left a lasting legacy on the French medical imagination.
For further exploration, Léo Bernard’s book Hippocrate initié is recommended for a detailed account of these currents, their origins, controversies, and continuing echoes in medical debates to this day.
