1 This proposition will be clear to everyone, who 2 remembers that from the given definition of any thing the 3 intellect infers several properties, which really necessarily 4 follow therefrom (that is, from the actual essence of the thing 5 defined); and it infers more properties in proportion as the 6 definition of the thing expresses more reality, that is, in 7 proportion as the essence of the thing defined involves more 8 reality. Now, as the divine nature has absolutely infinite 9 attributes (by Def. vi.), of which each expresses infinite 10 essence after its kind, it follows that from the necessity of its 11 nature an infinite number of things (that is, everything which 12 can fall within the sphere of an infinite intellect) must 13 necessarily follow.
