Meaning

Virtus here primarily means intellectual or ethical excellence, rather than merely effective power. It is a qualitas because its presence characterizes a soul while the soul can remain without it. Individuus and indivisibilis both mean indivisible in this argument, not an individual person.

Use in the book

The proof starts with a dilemma: a bodily quality touching a divisible region would share its division; one touching only a point would be a quality of that point rather than of the body. Ficino then proposes that the soul is the subject of an indivisible quality, virtue, so cannot itself be a body.

He separates virtues in intellect from virtues in appetite, including rational and irrational appetite. His contemplative group comprises wisdom of divine things, knowledge of nature, civil prudence and skill in human works. His moral group comprises justice, which gives each what is due, courage, which removes fear's impediment, and temperance, which repels the softness of desire. These descriptions are attributed to Plato. The local classification should be preserved even where it differs from a reader's customary modern division of “theoretical” and “practical.”

Magnitude is denied to both groups: a large person need not be wiser or more just, and knowledge of a large body is not simply a larger piece of knowledge. Subsequent arguments from sudden attainment, indivisible end and coexistence without spatial interference develop the premise of indivisibility. Finally, soul is not merely a passive subject receiving these qualities; it is also their principle. Ficino gives that productive role special weight in the immortality inference.

VIII.3.1The point-or-region dilemma is followed by the classification and definitions of virtues.
VIII.3.6Indivisible origin and end are joined to coexistence without confusion.
VIII.3.8Soul is both subject and source of virtues; its magnitude is rejected as a mistaken question.

Translation in this edition

The edition translates both individuus and indivisibilis as “indivisible” here. In VIII.3.8, speculativa fugit and moralis fugat deliberately differ: contemplation flees mortal things, while moral virtue drives them away.

anima

anima. Printed forms: anima; animae; animam; animarum; animas.

Soul as a life-giving principle, whose body, qualities, powers and operations must be distinguished. Book VI tests alternative identifications of soul and asks what human soul must be to occupy the immortal third essence; a conditional soul-body is an opponent’s hypothesis, not Ficino’s conclusion. References: VI.1.1, VI.1.6, VI.3.1, VI.13.1. See Divine production and the third essence.

Soul as the living subject and source of cognitive or ethical powers. It can remain while a virtue is absent and is argued to be more than a body or a form divided through a body. References: VIII.2.1, VIII.3.1, VIII.3.8, VIII.15.2. See Virtue as an indivisible quality.

fortitudo / timor

fortitudo / timor. Printed forms: formidini; fortis; fortiter; fortitudo; metus; timeat; timoris.

Courage, fear and the obstacles fear presents to honourable action. Courage removes an impediment; perfected justice and temperance also require resistance to fear, illustrating the virtues’ mutual dependence. References: VIII.3.1, VIII.3.7. See Virtue as an indivisible quality.

fugere / fugare

fugere / fugare. Printed forms: fugat; fugit.

To flee and to put to flight, deliberately contrasted verbs. Contemplative virtue withdraws from mortal things; moral virtue actively repels their disordered rule. The Latin assigns distinct roles. References: VIII.3.8. See Virtue as an indivisible quality.

inesse

inesse. Printed forms: inerit; inesse; inesset; inest; insunt.

Being in or inhering in a subject, without necessarily occupying a bodily space. Virtue's presence characterizes soul, and forms coexist within mind; the mode of inherence is exactly what the bodily-quality arguments test. References: VIII.2.3, VIII.2.7, VIII.3.5, VIII.3.7. See Virtue as an indivisible quality.

mollities appetitus

mollities appetitus. Printed forms: mollitiem.

Enfeebling softness of appetite, the moral impediment countered by temperance. This moral sense in the virtue definitions differs from excessive bodily softness of limbs in the earlier art-and-instruments comparison. References: VIII.3.1. See Virtue as an indivisible quality.

ortus / finis virtutis

ortus / finis virtutis. Printed forms: finem; finis; originem; ortus.

The origin and end of virtue, treated as evidence of its nature. An indivisible attainment and nonbodily goal together support the inference that the virtue itself is indivisible. References: VIII.3.6. See Virtue as an indivisible quality.

qualitas

qualitas. Printed forms: qualitas; Qualitas; qualitate; qualitatem; qualitates; Qualitates; qualitati; qualitatibus; qualitatis; qualitatum.

Quality, a form or power inhering in a subject and, when bodily, extended and altered with it. Quality has three causes in V.52 3 4 5 6 7 8 9's analysis and serves as an instrument of natural action; it is not automatically a moral quality. References: V.3.1, V.4.10, V.5.3, V.5.4, V.5.9, V.14.9. See Four causes and graded dependence.

A determination qualifying an underlying body. The second theory replaces bodily bulk by a quality spread through it; the third localizes a point belonging to that quality. References: VI.1.3, VI.1.4. See Constitution, localized point and harmony.

A characterizing quality whose mode of inherence matters for the subject possessing it. A divisible body's quality is spatially distributed; indivisible virtue is therefore used to establish a nonbodily subject. References: VIII.3.1, VIII.3.8, VIII.10.2, VIII.14.1. See Virtue as an indivisible quality.

sapientia / scientia / prudentia / ars

sapientia / scientia / prudentia / ars. Printed forms: ars; prudentia; prudentiam; sapientia; scientia.

Wisdom, knowledge, practical discernment and skill as the intellectual virtues enumerated here. Their respective objects are divine things, natural things, civic matters and human works; preserve this local classification rather than imposing another scheme. References: VIII.3.1, VIII.3.7. See Virtue as an indivisible quality.

speculativus / moralis

speculativus / moralis. Printed forms: morales; moralibus; Moralis; moralis; speculativa; speculativae.

Contemplative and moral, distinguishing virtues of intellect from virtues formed in appetite. The first arise and operate in contemplation; the second through custom and conduct, although the local contemplative list includes civic prudence and art. References: VIII.3.1, VIII.3.5, VIII.3.6, VIII.3.7, VIII.3.8. See Virtue as an indivisible quality.

subiectum / receptaculum

subiectum / receptaculum. Printed forms: receptaculum; subiecto; subiectum.

Subject of inherence or receptacle, not necessarily a spatial container. Soul bears indivisible virtues but is also their source; its role exceeds merely receiving a quality from elsewhere. References: VIII.3.8, VIII.4.1. See Virtue as an indivisible quality.

virtus

virtus. Printed forms: vi; vim; vires; viribus; virtus; virtute; virtutem; virtutes; virtuti; virtutibus; virtutis; Virtutum; virtutum; vis.

Effective power, the capacity whose act is operation. Creaturely power inheres in essence and is limited by that subject, unlike divine infinite creative power. References: V.1.4, V.4.1, V.4.2, V.4.6, V.4.10, V.13.7, V.13.9, V.13.12, V.13.13. See Creature, power and operation.

Excellence or effective power; the chapter on virtue specifies intellectual and moral perfection. Virtue is an indivisible quality of soul, while the closing book uses the same noun for enlarged powers of knowing, willing and living. References: VIII.3.1, VIII.3.6, VIII.3.8, VIII.16.4. See Virtue as an indivisible quality.

voluntas constans

voluntas constans. Printed forms: constans; dictaverit; eligendi; voluntas.

Steadfast will to choose what reason dictates. This definition supplies the ethical counterpart to the indivisible intellectual act; divided assent would fail to be the completed virtue described. References: VIII.3.5. See Virtue as an indivisible quality.
