E2P10S
Scholium — Part II
Latin
Demonstratur etiam hæc propositio ex propositione 5 partis I nempe quod duæ ejusdem naturæ substantiæ non dentur. Cum autem plures homines existere possint, ergo id quod hominis formam constituit, non est esse substantiæ. Patet præterea hæc propositio ex reliquis substantiæ proprietatibus videlicet quod substantia sit sua natura infinita, immutabilis, indivisibilis etc. ut facile unusquisque videre potest.
English (Elwes 1883)
This proposition may also be proved from I.v., in which it is shown that there cannot be two substances of the same nature; for as there may be many men, the being of substance is not that which constitutes the actual being of man. Again, the proposition is evident from the other properties of substance--namely, that substance is in its nature infinite, immutable, indivisible, &c., as anyone may see for himself.
Modern English
This proposition is also demonstrated by E1P5, namely, that there cannot be two substances of the same nature (E1P5). Since several men can exist, what constitutes the form of man is not being a substance. Beyond this, the proposition is evident from the remaining properties of substance: that substance is by its nature infinite, immutable, indivisible, and so on, as anyone can see for themselves.
