Meaning

Spiritus in chapter 6 is explicitly a very subtle, luminous little body. It is neither the incorporeal soul nor simply modern breath. Copulare joins; insinuare describes the soul entering or intimately engaging a medium akin to itself.

Use in the book

Ficino explains the joining of pure soul to gross earthly body through a mediating spirit generated by the heart’s heat from the finest blood. It diffuses through the body; the soul first gives it life and motion and through it governs the larger body. The language of kinship explains why this intermediary is fitted for the relation, but does not abolish the difference between a bodily medium and the soul that animates it.

The physician’s cut makes the distinction concrete. Flesh is severed; the spirit infused through it is partly loosened and partly contracts inward. Touch perceives the bodily event, while imagination attends to the perception, judges it and shares the distress. The concluding fourfold allocation is exact: bodily affection in flesh, torment in spirit, sensation in touch, and shared suffering in imagination. They are associated aspects of one event, not four names for a single material injury.

This physiology is Ficino’s historical explanatory account. Its fine body generated from blood should not be renamed a nerve impulse or treated as established medicine. The following argument moreover denies that the injury passes into the soul’s substance. To make the soul another even finer body immersed in the larger body would defeat the distinction chapter 6 is trying to secure.

Places to read

VII.6.2Damage to flesh and spirit is distinguished from damage to soul.
VII.6.3An extremely subtle immersed body is excluded as the final sensory judge.

Translation in this edition

The relative quem follows the neuter corpusculum while anticipating masculine spiritum; the sense remains explicitly bodily. VII.11.1’s “life-giving spirit” occurs in a different causal argument and should not automatically be assigned every physiological detail given here.

copulare / insinuare / cognatus

copulare / insinuare / cognatus. Printed forms: cognatissimo; copulatur; insinuans.

To join, enter intimately, and be most akin to. Soul engages a medium suited to itself and governs the body through it; affinity does not identify medium and soul. References: VII.6.1. See Bodily spirit and mediation.

cor / sanguis / calor

cor / sanguis / calor. Printed forms: calore; cordis; sanguinis.

Heart, blood and heat in the historical production of bodily spirit. Ficino says the heart’s heat generates spirit from the finest blood; the explanation is not adopted as contemporary physiology. References: VII.6.1. See Bodily spirit and mediation.

fundere / diffundere / permanare

fundere / diffundere / permanare. Printed forms: diffusum; fundit; permanat.

To diffuse, pour through, and pass onward. Spirit spreads through body; what passes into it is perceived by soul. The imagery does not require the soul itself to be spatially divided. References: VII.6.1. See Bodily spirit and mediation.

praestare vitam / vitalis

praestare vitam / vitalis. Printed forms: praestat; vitalem; vitam.

To bestow life and make living. Soul gives spirit life and motion before governing the larger body through that medium. References: VII.6.1. See Bodily spirit and mediation.

purus / crassus / terrenus

purus / crassus / terrenus. Printed forms: crasso; purissima; terreno.

Pure, gross and earthly as terms marking distance between soul and body. Their opposition motivates a mediating spirit rather than a direct equivalence of soul and bodily material. References: VII.6.1. See Bodily spirit and mediation.

regere / movere

regere / movere. Printed forms: movetque; regit.

To govern and move. These active relations oppose the later theory that soul is an outcome governed wholly by humors. References: VII.6.1. See Bodily spirit and mediation.

spiritus / corpusculum

spiritus / corpusculum. Printed forms: corpusculum; spiritum; Spiritus; spiritus.

The extremely fine luminous bodily medium joining soul to the gross body. Chapter 6 explicitly calls it a little body generated from blood; it must not be identified with the incorporeal soul. References: VII.6.1. See Bodily spirit and mediation.

tactus

tactus. Printed forms: tactu; tactus.

Touch as the soul’s sense universal throughout bodily members. Touch senses the surgical event while imagination judges and shares distress. References: VII.6.1. See Bodily spirit and mediation.

tenuis / lucidus

tenuis / lucidus. Printed forms: lucidissimumque; tenuissima; tenuissimum.

Extremely fine and luminous. The superlatives describe a subtle bodily spirit and its source in the finest blood; fineness does not make it incorporeal. References: VII.6.1. See Bodily spirit and mediation.
