Lex donum Dei est, æquitatis forma, norma justitiæ, divinæ voluntatis imago, salutis custodia, unio et consolidatio populorum, regula officiorum, exc… - John of Salisbury

Exquisita lectio singulorum, doctissimum; cauta electio meliorum, optimum facit.

Dicebat Bernardus Carnotensis nos esse quasi nanos gigantum humeris insidentes, ut possimus plura eis et remotiora videre, non utique proprii visus acumine, aut eminentia corporis, sed quia in altum subvehimur et extollimur magnitudine gigantea

To say that a thing "wholly pertains" to something else, or "does not pertain to it in any way," and that something "is predicated in a universal way" of something else, or "is completely alien to it" amount to the same thing. Nevertheless, while one form of expression is [now] in frequent use, the other has become practically obsolete, except so far as it may occasionally be admitted through mutual agreement. In Aristotle's day it was perhaps customary to use both of these forms of expression, but now one has replaced the other [simply] because usage has so decreed. p. 168
