At a Glance

The wordForms or types determine what creatures are; haecceity names the thisness by which a creature is this rather than that.
In the bookVaughan interprets logical terms as divine intelligible forms through Philoponus, then makes the opening of divine mind the desired demonstration.
In this editionThe fresh Greek translation and Vaughan’s historical English remain distinct, and the commentator’s role is explicit.

Meaning

Form here is not merely an outward shape. Vaughan calls the forms intellectual patterns within divine mind. Through them a creature is defined and receives individuation. He invokes Scotus’s “Haecceitie” to express the difference between this creature and another (Magia Adamica · p. 5). The phrase describes a determining relation: the creature is this and not that through the form that defines it.

The Greek Ὅρους, printed as the name given to these forms, is an inflected form meaning terms or bounds. Vaughan exploits the connection with terminating or bounding. The forms end or determine things, and so make them what they are. His explanation moves from a logical vocabulary of terms to a metaphysical account of the determinations in divine mind. It should be read as that interpretive move, rather than as a dictionary equivalence between every logical term and a divine form.

Use in the book

The passage arises within an attack on making revealed principles answer to Aristotle. Vaughan nevertheless quotes Aristotle’s admission, as he presents it, that opinion and reasoning admit falsehood. He then turns to a statement about a principle of knowledge through which terms are known (Magia Adamica · p. 4 · Passage 2). The use of an opponent’s authority is strategic: the asserted limits of reasoning open a route towards something prior to it.

Philoponus supplies the decisive interpretation. The quoted Greek identifies the principle as intellect, not ours but the divine intellect above us, and the terms as intelligible divine forms. Vaughan’s own English calls mind the principle or first cause of knowledge. The relation between these formulations matters. The historical rendering explicates the Greek in causal terms, whereas the modern fresh translation preserves the wording of principle more directly.

“According to Aristotle (if you trust the Comment)” marks a boundary in authority. Vaughan does not conceal that he reaches his theological Aristotle through an interpreter. A lexicon should retain that dependency rather than attributing the entire position directly to Aristotle without qualification. The force of the passage lies in how Vaughan recruits a commentary into his case for divine illumination.

The next conditional describes what follows if this mind unfolds itself and sheds light upon human beings. They will apprehend the forms within it. The object is neither a list of names alone nor a set of merely subjective ideas. Vaughan identifies what is apprehended with the divine determinations through which creatures are individuated. Knowledge is grounded in access to the source of their intelligibility.

Haecceity then gives the account a particularly sharp edge. A creature has its thisness, the feature by which it is this and not that. The term is introduced with “to speak with Scotus,” explicitly identifying a borrowed vocabulary. The passage does not develop Scotus’s complete account of individuation or compare rival scholastic theories. Its local function is to explain the determinacy of the creature through the forms just described.

Vaughan calls the expansion or opening of divine mind the demonstration one should seek. A mocked syllogism that runs on all fours is contrasted with illumination (Magia Adamica · p. 5). The word demonstration is therefore not discarded; its desired mode is relocated. This supports the adjoining account of faith: a reason can be given after communion of light, but not independently of it.

The human side of this opening follows immediately. The heaven of man must first be unfolded; the veil of understanding removed; the divine guest admitted. These images make receptivity part of knowing. The forms do not become human inventions because they are apprehended, and divine mind does not become identical with the individual human faculty. The passage sustains a distinction between the illuminating source and the understanding that receives it.

In this edition

The edition modernises Types as patterns in the opening sentence of Magia Adamica · p. 5. It translates Ὅρους as terms, then preserves the explanation in terms of determining or bounding. Haecceity remains a technical noun, explained by the following this-and-not-that clause. The Greek νοῦν belongs to the quoted phrase about intellect; it is not a new independent occurrence of a Latin or English lemma. The historical marginal explanation of the Latin knowledge statement remains marked as original apparatus.

Haecceity

Thisness, the individuation of a creature as this rather than that.

Vaughan invokes Scotus’s vocabulary within his account of divine forms defining creatures.
