La Gloriosa Asunción de María Santísima al Cielo
Lectura del libro de Judit (13:22-25; 15:10)
Bendíjote el Señor, comunicándote su poder, pues por tu medio ha aniquilado a nuestros enemigos. Bendita, oh hija, eres del Dios Altísimo sobre todas las mujeres de la tierra. Bendito sea el Señor, Creador de cielos y tierra, que dirigió tu mano para cortar la cabeza del caudillo de nuestros enemigos; y hoy ha hecho tan célebre tu nombre, que te alabarán perpetuamente cuantos conservaren en los siglos venideros la memoria de los prodigios del Señor; pues no has temido exponer tu vida por tu pueblo, viendo las angustias y la tribulación de tu gente, sino que has acudido a nuestro Dios para impedir su ruina. Tú eres la gloria de Jerusalén, Tú la alegría de Israel, Tú el honor de nuestro pueblo.
Continuación del Evangelio según San Lucas (1:41-50)
En aquel tiempo Isabel fué llena del Espíritu Santo y exclamó en alta voz diciendo: Bendita Tú entre todas las mujeres, y bendito el fruto de tu vientre. ¿Y de dónde a mí que venga a visitarme la Madre de mi Señor? Porque desde el momento en que he oído tu saludo, ha saltado de gozo el infante en mi seno. Feliz Tú porque has creído, porque se cumplirá en ti cuanto te ha dicho Dios. Contestó María: Mi alma engrandece al Señor, y mi espíritu se alegra en Dios mi Salvador; porque ha mirado la humildad de su esclava; por esto, pues, me llamarán dichosa todas las generaciones. Porque ha hecho en mí cosas grandes el que es Todopoderoso y cuyo Nombre es santo; y su misericordia se extiende de generación en generación a los que le temen.
Grande sois, Señor, y muy digno de toda alabanza, grande es vuestro poder, e infinita vuestra sabiduría: y no obstante eso, os quiere alabar el hombre, que es una pequeña parte de vuestras criaturas: el hombre que lleva en sí no solamente su mortalidad y la marca de su pecado, sino también la prueba y testimonio de que Vos resistís a los soberbios. Pero Vos mismo lo excitáis a ello de tal modo, que hacéis que se complazca en alabaros; porque nos criasteis para Vos, y está inquieto nuestro corazón hasta que descanse en Vos.

Logic I, Lesson 5: The Five Predicables, Pt. 3: Property & Accident
They also define it thus: "accident is that which may be present and not present to the same thing"; [they] also [define it as] "that which is neither genus, nor difference, nor species, nor property, yet is always inherent in a subject."
[Predication and the Predicables.] Having discussed all that were proposed, I mean, genus, species, difference, property, accident, we must declare what things are common, and what peculiar to them. Now it is common to them all to be predicated, as we have said, of many things, but genus (is predicated) of the species and individuals under it, and difference in like manner; but species, of the individuals under it; and property, both of the species, of which it is the property, and of the individuals under that species; again, accident (is predicated) both of species, and individuals. For "animal" is predicated of "horse" and "ox," which are species, and also of this particular horse and ox, which are individuals, but "irrational" is predicated of "horse" and "ox," and of individuals. Species however, as "man," is predicated of individuals alone, but property both of the species of which it is the property, and of the individuals under that species; as "risible" both of "man," and of individual men, but "black" of the species of crows, and of individuals, being an inseparable accident; and "moving," of "man" and "horse," being a separable accident. Notwithstanding, it is pre-eminently [predicated] of individuals, but secondarily of those things which comprehend individuals.
Logic I, Lesson 4: The Five Predicables, Pt. 2: Difference and the Porphyrian Tree
From Aristotle's Categories, 3:
If genera are different and co-ordinate [i.e., at the same level, and not subordinate to one another], their differentiae are themselves different in kind. Take as an instance the genus 'animal' and the genus 'knowledge'. 'With feet', 'two-footed', 'winged', 'aquatic', are differentiae of 'animal'; the species of knowledge are not distinguished by the same differentiae. One species of knowledge does not differ from another in being 'two-footed'.
But where one genus is subordinate to another, there is nothing to prevent their having the same differentiae: for the greater class is predicated of the lesser, so that all the differentiae of the predicate will be differentiae also of the subject.
From Porphyry's Isagoge to Aristotle's Categories, 3:
