At a Glance
- The wordLove is the desire and bond by which different natures come together; concord is their agreement in the work they perform.
- In the bookThe author makes love a principle of Nature, opposing both privation as a productive principle and a permanent warfare among the elements. The language ranges from divine self-communication to the propagation of individual creatures.
- In this edition“Love,” “desire,” “appetite,” and “concord” translate different Latin words. Their alliance is part of the argument, not a licence to treat them as synonyms.
- A place to readCanons 94–102, where Love’s three degrees lead directly into the dispute about the elements and their qualities.
Meaning
The central noun is Amor. Its scope is wider than affection between people: love names an outward movement towards another, a desire for form, a union of principles, and the inclination to reproduce. Concordia identifies the agreement that permits these different partners to act together. The author does not begin with identical things and then add a feeling between them. His problem is how unlike things can form a lasting, active whole.
The family and civic images are therefore consequential. A marriage binds matter and form; brothers share an inheritance; a treaty joins the qualities; a knot binds higher and lower things. These images distinguish participants while explaining their cooperation. Love is not mere sameness, and concord is not the abolition of differences.
Use in the book
The first extended movement begins with divine love. In canon 26 love reaches outside itself: divine Nature commands the extension of already-created light, multiplying its image. This is the author’s explanatory account, not a reported human emotion or a declaration that God first acquired a previously missing perfection. The account gives light’s expansion a direction and a purpose.
In canon 32 common participation in light becomes kinship. First matter and the elements, having been informed by light, enter a close love rather than the hostility attributed to them by common opinion. Their embrace permits bodies differentiated by species to arise. The shared origin does not make all compounds the same: precisely this affinity makes their different combinations possible.
Canon 45 then gives love a formal place in the argument. Those who add privation to matter and form as a third natural principle are accused of misrepresenting Nature’s intention. The end of generation is acquiring form; absence of form cannot explain the positive movement towards it. Love better deserves the title of principle because it mediates between the desiring and the desirable. The author does not deny that matter loses a form. He denies that the absence, considered merely as absence, performs the work attributed to the desire for a new one.
The personification becomes explicit in canon 94. Love, called the oldest god by Plato, is set over newborn Nature as her Genius. The historical margin names this role; it is not a heading supplied by the modern lexicon. The following canon orders love in three degrees: first between universal matter and form; next among the elements; finally in compounds drawn towards propagating their like. The allusions to Poros and Penia are immediately glossed as abundance and want. Their work here is to represent complementary inequality, not to supply an independent account of Plato’s dialogue.
The polemic of canons 96–98 tests whether another theory can accommodate the very appetite it acknowledges. The questions addressed to the Academy are challenges: how can matter desire form if its own constituents wage an endless civil war? In canon 98 the statement that nonhuman forms are drawn from matter’s hidden power is explicitly presented as the Academy’s doctrine. It must not be lifted out as an unqualified summary of everything this book later says about forms. The hypothetical resistant parents would produce monstrous rather than uniform offspring; the author deploys that consequence against perpetual elemental hostility.
Canons 101–102 supply the positive alternative. Form perfects matter into a proportionate concord. Intense qualities are moderated by union and then pass into the elemental family. Canon 111 asks to erase the contrary doctrine and inscribe Concord in its place. Yet the book has not forgotten unequal principles or actual disturbances. In canon 169 all powers contribute to generation; in canon 223 an earlier aversion is described as tamed into love. Concord is achieved and maintained through ordered relations. It is not a claim that every event experienced in the lower world is peaceful.
Canon 227 returns to the world’s double generative nature: the upper heavenly side is active and masculine, the lower elemental side passive and feminine, and earth receives heavenly seed as a womb. Life and strength are assigned to the male side, corruption and death to the female. This unequal historical scheme belongs to the author’s cosmological account; concord does not make its partners interchangeable or remove that hierarchy.

Translation in this edition
The translation preserves the difference between Amor, appetitus (“appetite,” canon 97), and cupidinem (“desire,” canon 98). “Magical knot” in canon 95 renders the phrase nodum magicum: the adjective belongs to the knot, not to every occurrence of love. The Academy’s “chief” in canon 97 is part of the author’s polemical presentation; its accompanying historical citation points to book 1, chapter 9, On Nature. These entries describe the author’s use of inherited authorities without independently confirming his attribution. The matrimonial and gendered comparisons remain historical language, not the lexicon’s account of human relationships.
