E3P6D
Demonstration — Part III
Latin
Res enim singulares modi sunt quibus Dei attributa certo et determinato modo exprimuntur (per corollarium propositionis 25 partis I) hoc est (per propositionem 34 partis I) res quæ Dei potentiam qua Deus est et agit, certo et determinato modo exprimunt neque ulla res aliquid in se habet a quo possit destrui sive quod ejus existentiam tollat (per propositionem 4 hujus) sed contra ei omni quod ejusdem existentiam potest tollere, opponitur (per propositionem præcedentem) adeoque quantum potest et in se est, in suo esse perseverare conatur. Q.E.D.
English (Elwes 1883)
Individual things are modes whereby the attributes of God are expressed in a given determinate manner (I. xxv. Coroll.); that is, (I. xxxiv.), they are things which express in a given determinate manner the power of God, whereby God is and acts; now no thing contains in itself anything whereby it can be destroyed, or which can take away its existence (III. iv.); but contrariwise it is opposed to all that could take away its existence (III. v.). Therefore, in so far as it can, and in so far as it is in itself, it endeavours to persist in its own being. Q.E.D.
Modern English
Individual things are modes by which God's attributes are expressed in a definite and determinate way (E1P25C), that is, (E1P34), they are things that express in a definite and determinate way the power by which God exists and acts. No thing contains in itself anything by which it could be destroyed or which could take away its existence (E3P4); on the contrary, it is opposed to everything that could take away its existence (E3P5). Therefore, insofar as it can and insofar as it is in itself, it strives to persist in its being. Q.E.D.
