Universa Philosophia

From this it follows that none in singular is necessary, because when it is removed, there can be another by which one runs: but if that power were in one alone, that one would be required in particular, as God is required for creating, because he alone has creative power, but in these no confusion is found, although by the word aliquis it seems to be signified, because by it we more frequently signify a confused mode of conceiving: observe these things, however, because from their confused knowledge many things are handed down less clearly. Likewise note that in a particular proposition signifying an act, the consequence holds in one singular with the others excluded, e.g. Some man runs, if Peter does not run, and there is no other but Paul, it follows well, therefore Paul runs, because there the thing is signified as exercised on the part of the thing, which is necessarily determinate: but in a particular proposition denoting a power, that exclusion of the others cannot be made, e.g. Some horse is required, one cannot say: Bucephalus is required, if the others are not required: because the power of running is found in the others as in Bucephalus, but the running is found in Paul alone, and the others can be excluded.
