CAP. 6. QUID EST ESSE DE OMNI ET QUOMODO PRAEMISSAE ET CONCLUSIO DEMONSTRATIONIS POSSUNT ESSE DE OMNI?.	Chapter 6. What is ‘being of all’, and in what way can premises and conclusions of demonstrations ‘be of all’?
Alia condicio tam praemissarum quam conclusionis demonstrationis est esse de omni, quia tam praemissa quam conclusio demonstrationis potest esse de omni.	Another condition of both the premises and conclusion of a demonstration is ‘being of all’, for premises as well as conclusions of demonstrations can ‘be of all’.
Est autem de omni, non quando praedicatum competit alicui contento sub subiecto et alicui non, nec quando uno tempore competit subiecto et alio non competit sibi, sed quando praedicatum omni contento sub subiecto et omni tempore competit subiecto.	Now ‘being of all’ is not when the predicate belongs to something contained under the subject but not to something else, nor is it when it belongs to the subject at one time but not at another. Rather, it is when the predicate belongs to everything contained under the subject and with the subject at every time.
Unde differentia est inter ‘de omni’ de quo loquitur Aristoteles in I Posteriorum et inter ‘de omni’ de quo loquitur in I Priorum. Nam ad ‘de omni’ de quo loquitur in libro Posteriorum requiritur quod praedicatum vere competat subiecto universaliter sumpto et pro omni tempore.	Hence there is a difference between the "of all" of which Aristotle speaks in Posterior Analytics I and the "of all" of which he speaks in Prior Analytics I. For it is required for the "of all" that he speaks of in the Posterior Analytics that the predicate truly belong to the subject taken universally, and for every time.
Ad ‘de omni’ autem de quo loquitur in libro Priorum non requiritur nisi quod per talem propositionem denotetur praedicatum praedicari de subiecto universaliter sumpto, sive vere praedicetur de eo sive non.	For the "of all" spoken of in the Prior Analytics it is only required that through such a proposition it is denoted that the predicated is predicated of the subject taken universally, whether it be truly predicated of it or not.
Unde haec est de omni ‘omnis homo est asinus’, non obstante quod sit falsa, quia est universalis.	Hence this is ‘of all’, "Every man is a donkey," for it is universal even if it is false.
