Meaning

Exercitus is an army; dux a commander, leader or guide; princeps the ruling head; and ordinator one who arranges. Dirigere emphasizes direction toward a destination or end. The two order-relations distinguish the mutual arrangement of a collective body's parts from the orientation of the whole toward its leader. Military vocabulary can therefore supply a metaphysical comparison without making every occurrence of dux military.

Use in the book

The army supplies a relational example: its parts are ordered to one another because the entire army is ordered to one commander. The point is not merely that a powerful ruler imposes obedience. It is that one common orientation explains how mutually diverse parts belong to a single arrangement.

The vocabulary then broadens. God is the world’s single arranger; God as guide and light enables action and seeking; God is a common rather than a private guide. These images explain universal causal scope. They do not make the divine cause a bodily commander standing beside the cosmic army or turn the philosophical example into advice about political government.

Ficino attributes to Aristotle an army comparison: relations among the army’s parts and their relation to the whole proceed from the whole’s ordering toward one commander. The world’s parts likewise derive their common coordination from the whole’s relation to God. The next unit says that the army’s order is “in” the commander, providing a model for the whole world’s order being in God. This is an explanatory “in,” concerning intelligible direction; the troops are not bodily contained in the commander. The analogy establishes how many different agents can act within one order without becoming identical. It also points toward the later question whether subordinate angelic or psychic governance displaces the first ruler. Ficino’s answer is that such governance remains dependent on God.

Translation in this edition

The rendering “guide” rather than “commander” in II.6.9 and II.7.6 suits those wider contexts. In II.13.8, “books on divine matters” represents in libris divinorum. This article reports Ficino's attribution and his use of the comparison; it does not independently certify a precise Aristotelian quotation or identify a modern military doctrine.

Aristoteles

Aristoteles. Printed forms: Aristoteles.

Aristotle as invoked authority. Ficino attributes the army analogy and inward movement comparison to Aristotelian works; the lexical record does not independently authenticate those attributions. References: II.13.8, II.13.12. See Army and commander.

dominari / praevalere

dominari / praevalere. Printed forms: dominatur; praevaleret.

To rule or prevail. An always-prevailing will alone would qualify as God in the rival-god dilemma; necessity rules in the cited Orphic saying. References: II.2.14, II.7.11. See Army and commander.

exercitus / dux

exercitus / dux. Printed forms: ducem; dux; exercitus.

Army and commander or guide. Military coordination illustrates relation to one source; guide later names God’s universal enabling role. References: II.2.8, II.6.9, II.7.6. See Army and commander.

exercitus / dux / princeps

exercitus / dux / princeps. Printed forms: duce; ducem; exercitus; principe.

Army / commander / sovereign. The army’s internal order derives from its relation to one leader, illustrating the world’s dependence on one ruling source. References: II.13.8, II.13.9. See Army and commander.

principatus / gubernare / regere

principatus / gubernare / regere. Printed forms: gubernando; gubernatore; princeps; principem; regit.

Governance, leadership, or preeminence. The common ruler of species and cosmic governor differ from an animating mind’s localized governance within the reported presence theory. References: II.2.7, II.4.7, II.6.11, II.6.24. See Army and commander.
