eBook di filosofia: G.B. della Porta, Della fisionomia dell’huomo


Giovanni Battista della Porta, Della fisionomia dell’huomo, 1644

“Physiognomonics, a proto- or pseudo-science on the rise in the sixteenth century, sought to identify the visible affinities between all physical things. Physiognomonists like Porta detected such affinities everywhere, from plants and animals to the bodies and faces of humans, and even further up the ontological scale to the appearance of the planets. Porta’s physiognomonics provides cartographies of the outward appearance of physical bodies aimed at predicting the soul’s hidden inclinations or dispositions (past, present or future). Porta’s massive effort to map the exterior appearances of all animated bodies runs in tandem with the contemporary medical approach towards cartographies of human bodies (as well as landscapes), exemplified most notably by Andreas Vesalius (1514–64) in his revolutionary anatomical studies.

Within its own historical context, physiognomonics was viewed as a rational science as good as, or perhaps even better than, the new anatomy, since it could be used for universal description and as a means to identify character traits. In the circular reasoning characteristic of his theory of magic, Porta’s physiognomonic assessments are based on resemblances in external appearance: for instance, men with a dark, Saturnine complexion evocative of dangerous animals are rendered very likely to go to prison (De ea naturalis physiognomoniae parte quae ad manuum lineas spectat ch. 12). This example highlights the aesthetics structuring Porta’s physiognomonics: beautiful bodies are also morally good. There is a direct association between beauty, virtue, success and health, as these traits all originate from a good temperament, that is, from a harmonious mixture of the elements. A monstrous body, on the other hand, indicates ill health, bad luck, and dubious moral inclinations.

A truly universal science, physiognomonics provides its master not only with a key for decoding the ciphers written into human faces (by relating them to the shapes of animals) or a manual for reading the lines engraved into the palms of our hands, but also (as Porta suggests) with diagnostic methods for understanding all of creation, from plants to stars. In this manner, physiognomonics may be described as the art that establishes a metonymic relationship between inorganic bodies and psychological qualities (Caputo 1990).

One important aspect of Porta’s physiognomonics is that it is not merely descriptive: bodies may be mapped and their future predicted, but they are nevertheless in a constant state of flux, transition, or mutability. Their essences are not exclusively determined by an invisible substantial form (soul) derived from unchangeable forms—and, in the case of human beings, immortal—as in previous traditions, but (more than ever) result from external circumstances. These environmental influences are decisive for the fate of individuals whose expressions and appearances are unstably shaped. A characteristic quotation illustrates Porta’s understanding of physiognomonics:

Through this art, we have helped many friends avoid dangers and ascend to honours. Shortly before I wrote these things, I counselled a friend of mine to avoid the company of a certain ugly and unlucky man, an advice he did not want to hear, as his acquaintance had promised him riches; at the end of the day, they were caught by the governor producing counterfeit money in a hide-out and shortly afterwards both ended on the gallows. (Coelestis physiognomonia, bk. 1, ch. 2)

It has often been noted that Porta opens perspectives on the sinister tradition of eugenics, not uncommon currency in European intellectual culture since its articulation in Plato’s Timaeus (90), where a handsome body is stipulated as the abode of a beautiful soul. Apart from the elemental influences altering body and mind, which can be reduced to qualities perceived through touch (such as hot/cold, dry/moist), Porta mentions nutrition, climate, and age as determinants of an individual’s mental and physical shape. Disease may also alter an individual’s mental disposition: as an example, Porta mentions fevers—since they dry up the brain, they may cause the patient to become more intelligent. Disease may even instill a capacity for divination. Alterations in outward appearance bear significant consequences for an individual’s behaviour and habits. (De humana pysiognomonia bk. 6, ch.1)

From the perspective of religious orthodoxy, the crucial question Porta addresses only with (well-advised) trepidation is whether a change in exterior form can also cause alterations to the soul—i.e., in the substantial and indelible form of humans (De humana pysiognomonia bk. 1, ch. 20). Here, Porta takes the position, more common to medical physiologists, that it is a physician’s intervention rather than moral philosophy that cures our bodies and minds. On this view, the body becomes a potential stage for medical intervention into the mental realm (Kodera 2010: ch. 8).

According to classical medicine, diseases are caused by an imbalance between body fluids—the temperaments. The concept of the temperaments or humoural mixtures in the human body was originally developed to describe physiological body states:

The four humours were real body fluids, to which largely hypothetical origins, sites and functions were ascribed. (Siraisi 1990: 105)

In late Antiquity and in the Middle Ages, the temperaments were understood to fall under the reign of the stars, which influence the generation and corruption of bodies in the sublunar sphere. In an important conceptual step, Porta turns the tables, contending that rather than being controlled by the stars, the medical humours are actually universal descriptors structuring the entire cosmos. With this move in a naturalistic direction, Porta strove to eclipse the astrological elements of his theory. Even though in the Coelestis physiognomonia he had declared astrology a vain discipline, Porta added an important qualification to this dismissal: astrology is an erroneous art, but only as long as divination from the stars is not based on the perceptible features of heavenly bodies. Hence, a fine physiognomonist will swiftly derive the relevant temperamental features from the visible appearance of the planets. In this way, all natural bodies remain substantiae signatae, cosmically predisposed substances bearing inscriptions of universal signs. The astrological system of categorization was restricted to the medical temperaments, thus associating celestial bodies with a system of signs that pertained to medicine and hence to a lower level in the hierarchy of being. Instead of governing the lower bodies, the stars become subject to the same laws as earthly bodies (Coelestis physiognomonia, proemium). In following the Neoplatonic cosmology outlined above, the attendant levelling of celestial hierarchies constitutes a break with Peripatetic cosmologies.

Initially, Porta’s naturalized version of astrology was probably a mere maneuver for detouring around the ecclesiastical censorship on the divinatory arts; in the first edition of the Magia (1558) Porta had fully embraced astrological causation, as well as the decisive role of an auspicious astrological moment for magical operations, especially the confection of talismans as described by Ficino in the De vita. (Magia 1558: bk. 1, chs. 15–17; Trabucco 2002, 2005). However, close alignment of astrology with medical humours and physiognomonics is well in accordance with Porta’s larger aim of naturalizing the entire cosmos. In his circular reasoning, Porta’s cosmos becomes more and more anthropomorphic, as universal signatures are imprinted not only into human beings, but also share these physical traits with the stars, animals, herbs and even stones (as explained in Porta’s Phytognomonica).” (tratto dalla Stanford Encyclopedia of Philosophy)
