Alan of Lille (1120–1202)
Alan's theological rules, wherein he sets forth over a hundred concise maxims.
Prologus I: Theologicae regulae
Regula I: Monas est, qua quaelibet res est una.
Regula II: In supercoelesti unitas, in coelesti alteritas, in subcoelesti pluralitas.
Regula III: Monas gignit monadem, et in se suum reflectit ardorem.
Regula IV: In Patre unitas, in Filio aequalitas, in Spiritu sancto unitatis aequalitatisque connexio.
Regula V: Sola monas est alpha et omega sine alpha et omega.
Regula VI: Omne limitatum alpha et omega aut est bonum ab alpha, aut est bonum ab alpha et omega.
Regula VII: Deus est spaera intelligibilis, cujus centrum ubique, circumferentia nusquam.
Regula VIII: Deus est cui quidlibet quod est, est esse omne quod est.
Regula IX: Quidquid est in Deo, Deus est.
Regula X: Omnis praedicatio de Creatore facta, copulata est atque conjuncta.
Regula XI: Omne simplex esse suum, et id quod est, unum habet.
Regula XII: Nullum simplex subjectum esse potest.
Regula XIII: Solum simplex est forma absque materiali subjecto, et substantia absque formali praedicato.
The simple alone is form without a material subject, and substance without a formal predicate.
Since that is truly called form which informs another and is informed by none, what is more truly form than God, who informs all things, and is informed by none? For he participates in nothing in order to be. But he is not such a form as to inhere in a subject; but rather he is without any subject, that is, abstract. Whence follows, without material subject, and substance; not because he underlies a property, but because all things subsist through him. Whence follows without formal predicate, because no formal predicate is predicated of him.
