Paracelso/en

Theophrastus Phillippus Aureolus Bombastus von Hohenheim, known as Paracelsus (1493 or 1494 – Salzburg, 24 September 1541), is the Swiss physician, alchemist, astrologer, and philosopher whose work refounded Renaissance Western medicine on spagyric, astral, and iatrochemical bases. It is to Paracelsus that we owe the introduction of the third alchemical principle — Salt — alongside the Sulphur and Mercury of the previous tradition, thus constituting the Tria Prima that would become the foundation of all post-Renaissance alchemy and, through the reinterpretation of Oswald Wirth, the typological matrix of the Paret Method.

Paracelsus is one of the pivotal figures of the third axis of the Paret Method School, which has adopted his doctrine of the three principles as a reference grid for non-verbal diagnosis and initiatory practice. The pages Tria Prima, I sei tipi caratteriali nella mappa polivagale, Mercurio Filosofico, and Le Flux Magnétique et les Savoirs Anciens directly refer to his work.

I. Life

Paracelsus was born in 1493 (or 1494, sources disagree) in Einsiedeln, in the Swiss canton of Schwyz. His father Wilhelm Bombast von Hohenheim, himself a physician and alchemist, initiated him early into the natural sciences and medical practice. His mother died when the young Theophrastus was still a child, and father and son moved to Villach, in Carinthia.

Paracelsus studied at numerous European universities — Basel, Vienna, Ferrara — and obtained his doctorate in medicine probably in Ferrara around 1515-1516. In the following years he traveled extensively: Italy, France, Spain, the Netherlands, England, Scandinavia, Russia, Poland, Constantinople, the Holy Land. From each region he gathered medical practices, pharmacological knowledge, metallurgical and alchemical traditions, conversing with barbers, midwives, millers, peasants, miners as much as with academic scholars. It is this openness — exceptional for his time — that founded his method.

In 1527 Paracelsus obtained the chair of medicine at the University of Basel. He opened his course with a sensational gesture: he publicly burned the canonical texts of Galenic medicine and of Avicenna in front of the students, declaring that he taught medicine not from books but from the book of Nature. He also taught in German instead of Latin, scandalizing his colleagues and opening the university to the non-Latinist populace. The opposition of the academic body and the apothecaries (Paracelsus prescribed simple and inexpensive medications, in contrast to the complex and costly recipes of the time) forced him to flee Basel as early as 1528.

The following years were a constant wandering: Colmar, Strasbourg, Nuremberg, St. Gallen, Innsbruck, Augsburg, Villach, and finally Salzburg, where he died on 24 September 1541, under circumstances never fully clarified. Popular legend speaks of murder by henchmen paid by the hostile medical world; contemporary historiography more soberly leans towards natural causes aggravated by the privations of itinerant life.

II. The refoundation of medicine

Paracelsus's medical work revolves around four principles that overturn the Galenic medicine of his time:

The physician learns from Nature, not from books. Direct observation of the patient, their constitution, their environment, their biography, takes precedence over the citation of auctoritates.
What becomes ill in the body is the microcosm, an expression of the macrocosm. Diseases have astral, mineral, dietary, psychic causes — a multidimensional framework that anticipates psychosomatic medicine and the systemic approach by centuries.
The cure acts on the principle, not on the symptoms. Spagyric medicine extracts from plants and minerals their energetic quintessence, which acts on the three principles (Sulphur, Mercury, Salt) of the patient to restore balance.
The physician is also an alchemist, and alchemy is also a medicine. The separation between medical theory and chemical practice is abolished: the Paracelsian physician works in the laboratory as much as at the bedside.

This refoundation establishes iatrochemistry (medical chemistry) and profoundly influences subsequent centuries: Jan Baptist van Helmont, Robert Boyle, Georg Ernst Stahl, and through them modern chemistry and pharmacology.

III. The doctrine of the three principles

Paracelsus's most enduring contribution to the alchemical tradition is the formulation of the Tria Prima: the three fundamental principles of the living that replace, without eliminating, the four elements of the Greek tradition.

Sulphur (Sulphur) — the principle of the soul, of heat, of passion, of active combustion. That which burns. Corresponds to the vascular, the choleric, the sympathetic polyvagal.
Mercury (Mercurius) — the principle of the spirit, of mediation, of fluidity, of intelligence in motion. That which evaporates. Corresponds to the diencephalic, the nervous, the ventral vagal polyvagal.
Salt (Sal) — the principle of the body, of stability, of crystallization, of materialization. That which remains in the crucible. Corresponds to the hepatorenal, the melancholic, the dorsal vagal polyvagal.

The introduction of Salt — the third principle absent in the Greek and Arabic alchemical tradition — is Paracelsus's decisive innovation: it accounts for the dimension of the body that the previous Sulphur-Mercury pair could not describe. Without Salt, the Tria Prima would have remained a map of the soul and spirit incapable of understanding corporeality — exactly the error that modern thought later repeated in a Cartesian dualist key, and which the Paret Method recovers through the Paracelsian return to the ternary of body-soul-spirit.

IV. Spagyria

Spagyria (from the Greek spao = «to separate» and ageiro = «to reunite») is the Paracelsian name for the operation that works on the three principles. It is articulated in three phases: separation, purification, recomposition (see Tria Prima for detailed treatment).

Paracelsus applied spagyria to the preparation of medicinal substances — distilling from plants, minerals, and metals their energetic «quintessence» transferable to the patient. The Paret Method School extends the same logic to human work on the character type: inner spagyria is the sequence by which the student recognizes their own prevalent type, distinguishes it from the missing principles, purifies the excesses, and progressively integrates the three principles into Presenza Integrale — an outcome that the Paracelsian tradition calls Mercurio Filosofico.

V. Microcosm and macrocosm

For Paracelsus, the human being is a microcosm that reflects the structure of the cosmic macrocosm. The seven traditional planets (Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon) have precise correspondences with organs, temperaments, emotions, phases of illness. The stars do not determine human life — on this Paracelsus distances himself from deterministic astrology — but participate in the orchestration of the living, and their reading helps the physician understand the complete picture.

This vision is formalized in the Paracelsian alchemical Tetraktys — an adaptation of the Pythagorean tetrad to the ternary of principles, described in the page Tria Prima — in which the four elements, the three principles, the Silver-Gold duality, and the unity of Divine Light are composed into a single stratified structure.

Marco Paret in Flux Magnétique (2017) reconstructs this vision in detail and shows how the binary planetary division of the four Hippocratic-Galenic temperaments (Sanguine, Choleric, Melancholic, Phlegmatic) produces the eight sub-types that numerically converge with the eight logismoi of Evagrius Ponticus, with the nine types of the enneagram, and with the six contemporary polyvagal states.

VI. Paracelsus and magnetism

Paracelsus is considered by the magnetic and mesmeric tradition one of the historical fathers of work on human magnetism. Already in his works he describes a magnetic vital force (Munia or Mumia) that the physician can transfer to the patient through contact, gaze, magnetized substances. He anticipates by two centuries the work of Franz Anton Mesmer (1734-1815), who will reformulate these intuitions in the doctrine of animal magnetism at the base of the French and Italian mesmeric tradition.

Oswald Wirth in Symbolisme hermétique explicitly cites Paracelsus and Mesmer as two stages of the same tradition, and Marco Paret in Flux Magnétique takes up and extends this filiation, showing how the magnetic practice of the School — through Caravelli, Di Pisa, and beyond — can be read as an operational continuation of the Paracelsian work on the three principles.

VII. Main works

Paracelsus left an immense corpus, largely unpublished during his lifetime, reconstructed from notes collected by disciples and published in subsequent generations. The most relevant works for the tradition that the Paret Method integrates are:

Opus Paramirum (~1531) — central text on the Tria Prima and the theory of principles.
Volumen Paramirum — on the five causes of disease (astral, poison, natural, spiritual, divine).
De Natura Rerum — on natural processes and the generation of life.
Archidoxis (~1526) — doctrinal synthesis on the quintessence and spagyric remedies.
De Vita Longa — on the art of prolonging life through work on the principles.
Astronomia Magna (1537-1538) — synthesis of the microcosm-macrocosm vision.

VIII. Legacy

Paracelsus's influence on subsequent centuries is enormous and ramified:

Iatrochemistry — van Helmont, Glauber, Tachenius, and the 18th-century refoundation of chemistry.
Symbolic and operative alchemy — Khunrath, Basilius Valentinus, Sendivogius, Eirenaeus Philalethes.
Anthroposophical medicine — Rudolf Steiner (20th cent.) explicitly recovers the Paracelsian framework.
Magnetic and mesmeric tradition — Mesmer, Lafontaine, Donato, and the Italian continuation up to the Paret Method.
Depth psychology — Carl Gustav Jung dedicates two of his major books to Paracelsian symbolism (Paracelsica 1942, Mysterium Coniunctionis 1955-1956).
Modern Francophone hermetic syntheses — Oswald Wirth in particular, through whom the Paracelsian doctrine entered the initiatory and typological tradition of the Paret Method School.
