Meaning

Composition is the joining of several constituents. Unio plurium makes its plurality explicit. Coagulum and conglutinare furnish the concrete image of an inward binder or glue; the image does not turn the unifying soul into a bodily adhesive.

Use in the book

Ficino splits the assertion that soul is concord into two senses: the composition itself of humors and members, or the proportion governing that composition. Against the first, he asks how bodily compositions could correspond to the soul and its powers. Bodily structure is known to natural philosophers; the composition of intellect, sensation and appetite is not comparably transparent. The difficulty is not solved by reciting a list of faculties.

A positive causal distinction follows. Composition is union of many, but many are unified by one. Ficino specifies an inward one, present among the many like glue binding them. That implanted power from which the members’ union comes is better called soul than the union produced by it. This restates in another vocabulary the difference between the tempering source and vital harmony as outcome.

The remainder of the chapter reinforces the unity of life. Distinct tissues have different proportions, yet one animal needs one form, mover and ruler. Bone, nerve and flesh cannot simply receive independent souls from their different mixtures. The argument distinguishes a multiplicity of instruments and conditions from a multiplicity of animating subjects. It does not deny that the living being has differentiated powers; it denies that merely listing or joining them explains the single source of their life.

Translation in this edition

The edition retains active quomodo vires singulae componant, with the soul supplied as understood object. Later witnesses read passive componantur. The active “how the individual powers compose [the soul]” should not silently become a claim about how each power is internally assembled.

coagulum / conglutinare

coagulum / conglutinare. Printed forms: coagulo; conglutinentur.

An inward binder or glue, and being glued together. The concrete image explains unification by an indwelling one without making soul a physical adhesive. References: VII.12.1. See Composition and inward unity.

componere

componere. Printed forms: componant; componatur; composita.

To compose, with active and passive constructions distinguished. The retained active componant asks how individual powers compose the soul; later passive readings ask how they are composed. References: VII.12.1. See Composition and inward unity.

compositio

compositio. Printed forms: Compositio; compositio; compositionem.

Composition as the union of bodily constituents. It is the first of two interpretations of soul-as-concord rejected in chapter 12; proportion within composition is the second. References: VII.12.1. See Composition and inward unity.

construere / constituere

construere / constituere. Printed forms: constituent; constituta; constitutam; construere.

To build or constitute a whole from its components. The body-building proposal must explain organs suited for sensation; simply combining nonsensing parts does not explain a sensing subject. References: VII.4.2, VII.8.1, VII.9.1, VII.9.2. See Composition and inward unity.

intellectus / sensus / appetitus

intellectus / sensus / appetitus. Printed forms: appetitu; intellectu; intellectus; intelligendi; intelligere; sensu.

Intellect, sensation and appetite as powers of soul. The difficulty of explaining how these compose a soul is not solved by knowing the bodily parts’ mixture. References: VII.12.1. See Composition and inward unity.

motor / rector / una forma

motor / rector / una forma. Printed forms: formam; motorem; rectorem.

One form, mover and ruler of the living being. The three roles converge on one soul as the explanation of one life amid different bodily members. References: VII.12.1. See Composition and inward unity.

unio plurium / vis insita

unio plurium / vis insita. Printed forms: insita; unio fit membrorum; unio plurium; uniuntur; vis insita.

Union of many and the inwardly implanted power producing that union. The one source unites the members; soul is identified with that source rather than the union resulting from it. References: VII.12.1. See Composition and inward unity.
