Meaning

The four names identify distinct cognitive activities in the account attributed to the Platonists. Sensus is bodily sensation; imaginatio collects and retains sensory appearances; phantasia recognizes and evaluates this particular represented thing; intelligentia or intellectus apprehends common natures and incorporeal accounts. The distinction is functional, not a list of four independent souls.

Use in the book

Book VIII begins the third route to the soul's incorporeality and immortality, through understanding, after the operations of nourishment and sensation. Socrates seeing Plato supplies a controlled example: the object stays recognizably the same while the conditions of apprehending it change. Sight receives Plato's likeness without his matter but still needs the living body present. Imagination no longer requires that presence and combines what the five senses separately supply. Phantasy judges the pictured man to be Plato, beautiful, good, a friend and a pupil. Intellect goes beyond this person, place and hour to humanity, beauty and goodness common to many.

These stages are not simply four degrees of photographic vividness. Phantasy adds judgment, yet remains tied to singular conditions. Intellect's distinctive objects include common natures and principles that are not extended as bodily pictures are. Nor is sensation's initial reception of an incorporeal likeness already equivalent to fully incorporeal understanding. The argument depends on discriminating how much material restriction remains at each stage.

Ficino explicitly allows phantasy and intellect to perform their different works simultaneously. He also later reminds the reader that intellect knows particulars as well as universals. The ladder therefore identifies relative independence from material conditions; it does not forbid interaction or deny lower objects to a higher faculty.

The portrait also separates the sensory channels from their internal coordination. Colour and outline are visible, voice audible; the same internal imagination can collect both while no single external sense performs all five senses' tasks. That unity and the ability to operate with an absent object explain why imagination rises farther above matter than sensation. Yet its contents remain received or conceived through sensation. Ficino therefore distinguishes freedom from a body's present proximity from freedom from the bodily character of the presentation itself.

The next transition should not be summarized simply as “interpretation.” Phantasy recognizes whose likeness is present and applies predicates not themselves visible shapes: good, beautiful, friend and pupil. This is why Ficino can describe it as dreaming of incorporeals. But the same passage denies it the rational account of substance. The distinction keeps meaningful recognition below full intellectual universality without reducing it to a passive picture. Its operations are richer than imagination's, and their limits are equally explicit.

Nor does the upward ordering entail that mind must become empty of sensible distinctions to know. In VIII.6 it compares individual limbs with each other and with the whole body; in VIII.12 it understands contraries together; in VIII.16 it ranges across all sensory classes. These applications depend on intellect retaining access to the materials it transcends in mode. The higher faculty's distinctive power is to know such contents without being limited to one organ's object or one image's circumstance. The argument concerns the knower's manner of possessing the objects, not the disappearance of bodies from knowledge.

Places to read

  1. VIII.1.1Socrates sees, remembers, and identifies Plato; each activity removes a different restriction.
  2. VIII.1.2, VIII.1.4Singular phantasy and universal intellect can work together; the four domains are restated.
  3. VIII.1.5Intellect also returns to particulars, and the new proof is related to earlier arguments from nutrition and sensation.

Translation in this edition

The edition deliberately distinguishes “imagination” from “phantasy.” Replacing both by imagination would erase the example's central transition. At VIII.1.1, spiritum is the ascent's nonbodily terminus; it is not the physiological “vital spirit” of VIII.2.3.

aggredi / exponere / ostendere

aggredi / exponere / ostendere. Printed forms: aggrediemur; exposuerimus; ostenderimus; ostendimus; ostendit.

Beginning an inquiry, setting out its structure and showing a conclusion. The opening explicitly announces a third proof-route through understanding and makes the account of cognitive faculties its preliminary task. References: VIII.1.1, VIII.1.5, VIII.3.1. See Four stages of cognition.

ascendere / surgere / evolare

ascendere / surgere / evolare. Printed forms: ascendimus; ascendit; Ascendit; evolat; surgendum; surgimus; Surgitque.

Ascending, rising and soaring, spatial images for increased freedom from material restriction. The faculties progress from body toward spirit, but phantasy has not yet wholly soared beyond matter. References: VIII.1.1, VIII.1.2, VIII.1.3. See Four stages of cognition.

imaginatio

imaginatio. Printed forms: imaginatio; Imaginatio; imaginationem; imaginationi.

The faculty collecting and retaining sensory likenesses, distinct here from recognitive phantasy. Socrates can imagine absent Plato, combining the five senses, but this collection alone does not identify the person or know substance. References: VIII.1.1, VIII.1.4, VIII.4.3. See Four stages of cognition.

incorporeus / incorporalis

incorporeus / incorporalis. Printed forms: incorporales; incorporalia; incorporalium; incorporea; incorporealem; incorporeas; incorporeis; incorporeum.

Not bodily; the degree and respect of freedom from material conditions can vary in the opening ascent. The image received by sense, phantasy's qualified intentions and the fully incorporeal principles of intellect must not be collapsed into one mode. References: VIII.1.1, VIII.1.2, VIII.1.4, VIII.1.5, VIII.2.1, VIII.2.7, VIII.3.8, VIII.4.5, VIII.10.1, VIII.10.2, VIII.13.1, VIII.15.2. See Four stages of cognition.

intelligere / intellectio

intelligere / intellectio. Printed forms: intellectio; intellectis; intelligat; intelligendae; intelligendi; intelligendo; intelligendum; intelligere; intelliget; Intelligit; intelligit; intelliguntur.

Understanding as an intellectual operation, not simply receiving a sensory impression. It includes universal apprehension, definition, comparison, knowledge of particulars and self-reflection, and is used to infer the nature of the active subject. References: VIII.1.1, VIII.1.5, VIII.4.1, VIII.4.2, VIII.4.3, VIII.4.9, VIII.4.13, VIII.5.1, VIII.5.2, VIII.6.1, VIII.9.1, VIII.10.1, VIII.13.2, VIII.15.1, VIII.15.2, VIII.16.1, VIII.16.4. See Four stages of cognition.

praesentia / absentia

praesentia / absentia. Printed forms: absens; absente; adsit; praesens; praesente; praesentia.

Being present or absent to a bodily event or member. Whole presence is used to explain awareness without abandonment of other living members; it must not be reduced to spatial filling. References: VII.5.1, VII.5.2, VII.6.1. See Whole presence and vital intensity.

Presence or absence of the original bodily object to the faculty's activity. Sight needs Plato present, whereas imagination can retain and combine his features when he is absent. References: VIII.1.1. See Four stages of cognition.

sapere

sapere. Printed forms: sapiens; sapientior; sapit.

Knowing or discerning; the related wisdom vocabulary adds an attained intellectual excellence. Imagination knows only what sense receives or conceives, while the virtue argument denies that greater bulk makes a person wiser. References: VIII.1.1, VIII.3.1. See Four stages of cognition.

sensus

sensus. Printed forms: sensibus; sensum; Sensus; sensus; sensuum.

Bodily sensation or the sensory faculty, restricted to particular objects and conditions of reception. Sensation requires the presented body, while intellect can compare sensory classes and reach universal accounts; receiving an incorporeal likeness does not erase this difference. References: VIII.1.1, VIII.1.4, VIII.2.8, VIII.16.1. See Four stages of cognition.

Socrates / Plato

Socrates / Plato. Printed forms: Plato; Platonem; Platonis; Socrates; Socratis.

The observer and observed person in the staged cognitive example. Their familiar relationship permits a shift from visible features to recognition of a friend and pupil, then to the humanity shared by others. References: VIII.1.1, VIII.1.2. See Four stages of cognition.

superare / excedere / excellere

superare / excedere / excellere. Printed forms: excedit; excellat; excellit; superat; supereminet; superet.

Surpassing in power, scope or excellence rather than necessarily in bodily size. A small person can overcome a large one, phantasy exceeds imagination, and intellectual power exceeds bodily restriction without becoming God. References: VIII.1.1, VIII.2.3, VIII.10.2, VIII.14.1, VIII.16.2, VIII.16.4. See Four stages of cognition.

versari / volutari / vagari

versari / volutari / vagari. Printed forms: vagatur; versatur; volutat.

Being occupied with, turning over and ranging among objects. Ficino allocates different object-domains to sense, imagination, phantasy and intellect; the movement is often figurative rather than spatial. References: VIII.1.1, VIII.1.2, VIII.1.4, VIII.7.1. See Four stages of cognition.
