Meaning

Frusta are severed pieces; compago is the organized structure joining a body. Interire means perishing, not dividing. New souls arising in suitable fragments are therefore not surviving numerical parts of the former soul.

Use in the book

Moving and sensing animal fragments appear to challenge indivisibility: if a body divides into two living bodies, why not suppose its soul divides into two souls? Ficino’s answer is strikingly qualified. The original soul perishes when the structure to which it was assigned dissolves. New souls arise immediately from the life of the world in fragments suited to receive them. A fragment can be suited because a lowly soul has few powers and operations and accordingly needs few bodily instruments. More perfect souls need diverse organs and do not live in detached single members.

The analogies preserve replacement rather than division. Cutting wood at a point destroys that point as the common boundary and produces new endpoints. Breaking a mirror removes the one image and yields two newly reflected images. Cutting the word Lucifer destroys its original meaning while leaving meaningful components. None makes one original indivisible entity numerically persist as two halves.

The final question explicitly invokes the Platonists and creeping creatures. The argument is therefore not a universal claim that every soul is deathless because indivisible, nor a modern account of regeneration. Within this passage, indivisibility is compatible with the disappearance of a low animal soul. That limitation is indispensable in a work devoted to immortality: the rational soul’s case cannot be secured by silently attributing to every soul what this chapter denies of these examples.

Translation in this edition

The base reading says in singulis membris non vivunt. Later witnesses omit non, reversing a crucial local qualification. This edition retains it: more perfect souls do not live in separate members. “Perishes” for interit must not be softened to “divides” or “withdraws” without textual warrant.

compago / resolvere

compago / resolvere. Printed forms: compago; resolvitur.

An organized bodily framework and its dissolution. The original low animal soul is said to perish when its assigned bodily organization dissolves. References: VII.5.4. See Severed animals and replacement souls.

frangere / recreare

frangere / recreare. Printed forms: fregeris; recreantur.

To break and to create anew. A broken mirror produces two new images after the first disappears; its original image is not itself cut in two. References: VII.5.4. See Severed animals and replacement souls.

frustum / secare

frustum / secare. Printed forms: frusta; frustis; secantur; secari; secatur; secetur.

A cut fragment and the action of severing. Moving animal fragments motivate the objection that dividing body seems to divide soul. References: VII.5.4. See Severed animals and replacement souls.

idoneus / vilis / perfectior

idoneus / vilis / perfectior. Printed forms: idoneis; perfectioribus; viles.

Suitable, lowly in powers, and more perfect or functionally richer. Few-power souls need few instruments; more perfect souls require the differentiated organs absent from detached members. References: VII.5.4. See Severed animals and replacement souls.

interire / perire / abire

interire / perire / abire. Printed forms: abit; interit; perit.

To perish or cease, and to depart or disappear. The old soul, cutting-point and mirror-image cease in their respective examples; none is simply divided into surviving halves. References: VII.5.4. See Severed animals and replacement souls.

lignum / extremum punctum

lignum / extremum punctum. Printed forms: extrema; lignum; puncta; puncto; punctum.

Wood and the new terminal points produced at its cut. The original indivisible cutting-point perishes; two endpoints arise, illustrating replacement rather than splitting an indivisible thing. References: VII.5.4. See Severed animals and replacement souls.

reptilia / secundum Platonicos

reptilia / secundum Platonicos. Printed forms: reptilia; secundum Platonicos.

Creeping animals and the explicit attribution to the Platonists. The closing question qualifies the scope of the animal-soul explanation rather than declaring every soul both indivisible and imperishable. References: VII.5.4. See Severed animals and replacement souls.

vita mundi / novae animae

vita mundi / novae animae. Printed forms: novae animae; vita mundi.

New souls arising from the life of the world. Ficino’s Platonist answer replaces the vanished animal soul with new souls in suitable severed pieces. References: VII.5.4. See Severed animals and replacement souls.

vivere

vivere. Printed forms: vivant; vivat; vivendi; vivens; vivent; vivente; viventem; viventium; vivere; vivit; Vivunt; vivunt; vixerat; vixit.

To live, the actuality corresponding to soul's essence as life. For soul, being is living; loss of life would therefore not leave the same soul as a lifeless thing. References: V.11.3, V.11.8, V.12.12, V.12.14, V.13.18, V.14.3, V.14.7, V.14.8. See Life and vivification.

To live, with the source of life under dispute. Living fragments motivate a Platonist replacement account; all composites would live if mere harmony were soul, a rejected consequence. References: VII.5.2, VII.5.4, VII.11.1. See Severed animals and replacement souls.
