Tool, implement; here an instrument for wool-working

Meaning

Tool, implement; here an instrument for wool-working.

Grammatical category: noun, neuter.

Use in the book

The genitive plural ὀργάνων gathers the mother’s wool-working implements after specific tools have been named. Lysis is forbidden to handle them, making equipment a concrete test of whether family membership confers practical permission. The term here is material and ordinary. It does not denote a bodily organ, a logical instrument, or an abstract “organon” of knowledge.

English renderings
instrument; organ; tool

Meaning

Organon is a means through which an operation is performed. It can be bodily, material, or part of a philosophical account of mediation.

Use in the book

The report on Hippasus describes number as a discriminating instrument of the god who fashions the cosmos. A Hermetic passage calls fire the instrument used by cosmic intellect in making. The instrument must be distinguished from the maker using it, even where its operation is indispensable to production.

Places to read

  1. I.49.32.6Number is described as the cosmic maker’s discriminating instrument.
  2. I.48.3.4Cosmic intellect uses fire instrumentally in craftsmanship.
  3. I.49.1a.3The body in the definition of soul is equipped with organs.

Translation in this edition

“Instrument” suits mediation in an activity; “organ” suits a bodily part where its function is at issue.

Organic and instrumental

Organikos relates a thing to organs or instruments. In the Aristotelian definition of soul at I.49.1a.3, it qualifies the natural body that has life potentially: a body equipped for the functions of life. “Organic” here should not be read in the modern chemical or agricultural sense. The adjective connects bodily organization with the capacities actualized in living.

Source note

Wachsmuth, volume I, printed pp. 311–312, 319, 364. In I.49.32.6, number remains the understood subject across the abbreviated accounts of different thinkers.

  • A place to readDistinguishes organs’ instrumental role from the cause of skilled performance and prefers form to blood-blend.

Meaning

Organon is an instrument or tool; the phrase means holding the rank or position of an instrument. Morphē is form, and dianoia intelligence or thinking. These terms articulate Theophrastus's objection to a blood-blend explanation of skilled capacities.

Use in the book

The tongue permits speaking and the hands permit making, but Theophrastus denies that their local mixture thereby supplies the cause of speaking or making well. Calling them instruments differentiates what an intelligent activity uses from what fully explains that activity. He proposes assigning the cause to form rather than a blend of blood, which he calls without intelligence.

This is a directed comparison, not a claim that an instrument can have no causal role whatsoever. The edition's caption “an instrument, not a cause” risks overstating the point. The Greek critic says one would do better to assign the cause to form: he is contesting explanatory priority and adequacy. Nor does the passage provide enough detail to decide exactly which sense of “form” or which account of intelligent agency he means in every case. The lexicon should retain those words as the later witness's analytical alternative, without making them Empedoclean categories or a fully expounded doctrine in this excerpt.

Places to read

  1. A 86 § 24 (polemical)Theophrastus, On the Senses 24. Distinguishes organs’ instrumental role from the cause of skilled performance and prefers form to blood-blend.
  2. A 86 §§ 10–11 (testimony)Theophrastus, On the Senses 11. Supplies the local-blend theory which the objection targets.

Translation in this edition

The linking words οὖσαν ἢ are supplied by Diels. The final argument remains clear, but a rigid modern opposition between “mere material” and “real cause” would flatten both the qualified wording and its later philosophical vocabulary.

Source note

The lexical connection between organ and instrument is visible in organon itself. The English “organ” can hide that connection by sounding exclusively anatomical.

Instrument

instrumentum; opifex; agens; agentia; medium; media; instrumenta; artifex

Instrumentum is a means or tool acting through the power of a principal agent; opifex and artifex name the maker or skilled worker.

Orientation

At a Glance

  • The wordInstrumentum is a means or tool acting through the power of a principal agent; opifex and artifex name the maker or skilled worker.
  • In the Platonic TheologyAn instrument is a real means of action whose efficacy depends on a principal agent.
  • In this editionII.7.24’s tamquam, “just as,” marks the tool comparison as analogical: angel is not said to be a material implement.
  • A place to readGod gives and preserves angelic being, power, and action

Meaning

Instrumentum is a means or tool acting through the power of a principal agent; opifex and artifex name the maker or skilled worker. Medium is an intermediary, not necessarily an inert object. Instrumental dependence is a relation of efficacy, not proof that a subordinate cause does nothing.

Use in the book

An instrument is a real means of action whose efficacy depends on a principal agent. Its dependence does not make it causally useless. The question is whether its power suffices to account for the whole effect, including the effect's form and ordering. A tool separated from its craftsman does not direct itself toward the intended work, and bodily qualities cannot independently explain the organized generation of living substance.

Book I uses this distinction to analyze fire producing fire. A particular fire is itself an effect before it acts as a producer. Neither another equal fire, the contrary elements, nor a distant heavenly body without an adequate intermediary supplies the sufficient account sought by the argument. Ficino arrives at an incorporeal substance that penetrates bodies, governs them, and employs their qualities as instruments. He does not deny that the qualities act; he denies that their efficacy is self-sufficient or that bare matter independently creates form.

The same relation explains angelic agency in Book II. God gives and preserves the angel's being, capacity, and activity, so God is the more fundamental source of the angel's works and their further effects. This is a causal comparison, not a claim that angel is materially constituted like a tool. Intermediaries nevertheless differentiate effects: one sunlight appears red or green through differently colored windows. God's fundamental agency therefore does not erase subordinate causes. A related argument about divine cognition says that intelligent minds would be unfitting instruments of a first mover wholly devoid of intelligence.

In Book IV, celestial influence requires a proximate living substance to participate in producing substantial life. Heaven also functions as an instrument of divine mind when it prepares bodies for intellectual souls, an effect exceeding heaven's independent bodily power. IV.1.68 adds a more specific premise: instruments through which living beings generate life are themselves alive, and heaven's generative role is taken to imply life. That is an additional biological analogy within Ficino's argument, not part of the word's basic definition.

Translation in this edition

II.7.24’s tamquam, “just as,” marks the tool comparison as analogical: angel is not said to be a material implement. II.7.31 retains both the contribution of sunlight and the difference made by particular glass, preserving dependent differentiation rather than autonomous secondary production.

conducere ad speciem

conducere ad speciem. Printed forms: ad speciem mentis perfectae conducit.

To contribute toward the realization of a higher kind. Heaven's bodily arranging activity requires intellectual direction when it prepares recipients for intellectual souls. References: IV.1.85. See Instrument.

instrumentum

instrumentum. Printed forms: instrumenta; instrumentum.

An instrument through which a higher cause acts. A fire’s present efficacy needs a superior source rather than merely the earlier local fire that may already be extinct. References: I.3.8, I.3.9, I.3.10. See Instrument.

instrumentum / opifex

instrumentum / opifex. Printed forms: instrumenta; instrumentum; opificis.

Instrument and craftsman or primary maker. Angel acts with received power like a tool, yet remains a genuine subordinate agent. References: II.7.24, II.9.5. See Instrument.

instrumentum vitae

instrumentum vitae. Printed forms: vitae alicuius instrumentum.

The instrument of a living source. The argument from living generative instruments in organisms is extended to heaven's generation of living things. References: IV.1.68. See Instrument.

seorsum

seorsum. Printed forms: seorsum.

Separately or apart. Independence is tested through the possibility of existing apart from the conditions and limits of accidents. References: II.11.5. See Separation and abstraction.

Apart or separately. An instrument apart from its craftsman cannot carry out the art's form; separation concerns causal sufficiency. References: IV.1.3. See Instrument.

subdere / subicere

subdere / subicere. Printed forms: subditur; subiciatur.

To subordinate to an agent or governing power. The celestial impulse can contribute to generation as the instrument of an element's common life. References: IV.1.3, IV.1.4. See Instrument.

Instrument and creative mediation

instrumentum; medium; principalis agens; subiectum; traducere; temporis intervallum; sine medio

Instrumentum is an instrument, an agent moved by another to act upon a recipient.

Orientation

At a Glance

  • The wordInstrumentum is an instrument, an agent moved by another to act upon a recipient.
  • In the Platonic TheologyV.4.10 makes qualities instruments through which rational soul moves matter.
  • In this editionThe phrase formam principalis agentis at V.13.14 means the form of the principal agent in this proposed instrumental arrangement.
  • A place to readQualities serve as instruments in soul’s movement of matter.

Meaning

Instrumentum is an instrument, an agent moved by another to act upon a recipient. Medium is an intermediary. Principalis agens names the governing agent in an instrumental action; it need not mean the absolutely First Cause of all being. Sine medio means without an intervening cause of the relevant kind.

Use in the book

V.4.10 makes qualities instruments through which rational soul moves matter. The example is genuinely causal: the instrument carries an agent’s operation into a receptive subject. The soul can therefore employ bodily powers without deriving its own essence from them.

V.13.14 tests whether an angel could have just that role in creating a soul: God the craftsman, angel the instrument. Ficino rejects it by analyzing what instruments do. They are moved by another, move something else, affect an underlying subject and convey the principal agent’s form through an interval of time. Creation from nothing lacks a subject and does not take place through motion or time. Its mode therefore cannot be transferred unchanged to this instrument model.

The following objection concerns power. If infinite creative power were first received in a finite angel, it would be delimited by the angel’s nature; it could not then perform an act requiring infinity. The two reasons are related but distinct: one concerns the structure of instrumental operation, the other limitation by a receiver.

The conclusion “without intermediary” concerns the soul’s creation and continuing dependence. It does not forbid every angelic illumination, assistance or ranked relation elsewhere. The same V.6 that distinguishes separate forms from infused powers allows beneficent power from God or angel. Scope matters.

Places to read

  1. V.4.10Qualities serve as instruments in soul’s movement of matter.
  2. V.6.1Infused beneficent power is distinguished from separately created subsistent form.
  3. V.13.14, V.13.15, V.13.16, V.13.17Angelic instrumental creation is rejected and immediate creation/preservation affirmed.

Translation in this edition

The phrase formam principalis agentis at V.13.14 means the form of the principal agent in this proposed instrumental arrangement. It should not be cited as though every occurrence of principalis were the technical name causa prima. The hypothetical arrangement is rejected, not adopted. The apparatus takes hanc in V.4.10 as the efficient power just mentioned: the first-moving power forms that subordinate power. The English follows this explicit editorial construal; this companion does not label it a mistranslation.

angelus

angelus. Printed forms: angelo; angelum; angelus.

Angel or angelic mind, a created intellectual rank superior to rational soul. V.523456789 distinguishes freedom from material inclination, while V.1323456789101112131415161718 denies that this finite being can create a soul, even as instrument. References: V.3.1, V.5.5, V.13.1, V.13.14, V.13.16. See Instrument and creative mediation.

instrumentum

instrumentum. Printed forms: instrumenta; instrumentis; instrumentum.

An instrument carrying a principal agent's action to a recipient. Bodily qualities serve soul instrumentally, but creation is said to lack the subject, motion and time required for instrumental action. References: V.4.10, V.13.14, V.14.8. See Instrument and creative mediation.

An organ or instrument fitted to a power’s activity. External senses, the bodily medium and nutritive heat are instruments in different contexts; none is simply the source of its own ordered use. References: VII.2.1, VII.6.3, VII.8.1, VII.9.2. See Nutrition, growth and the principal agent.

medium

medium. Printed forms: medio; medium; medius.

A middle term, intermediary or mean between extremes. The causal hierarchy requires mediating degrees, but immediate creation excludes an angelic instrument between soul and God. References: V.5.1, V.8.4, V.13.14, V.13.17, V.14.7. See Instrument and creative mediation.

principalis agens

principalis agens. Printed forms: principalis agentis.

The principal agent in a proposed instrumental operation. This relative causal term in the angel-as-instrument objection must not automatically be equated with the absolute title First Cause. References: V.13.14. See Instrument and creative mediation.

temporis intervallum

temporis intervallum. Printed forms: temporis intervallum.

An interval of time through which an instrumental operation proceeds. An instrument is moved by another, acts on a subject and conveys its principal agent’s form over time. Ficino invokes this structure to reject angelic instrumental creation, since creation requires neither a prior subject nor motion or time. References: V.13.14. See Instrument and creative mediation.

traducere

traducere. Printed forms: traducat.

To convey or carry across into another subject. An instrument transfers the principal agent's form over time, a structure Ficino denies to creation from nothing. References: V.13.14. See Instrument and creative mediation.
