E2P1D
Demonstration — Part II
Latin
Singulares cogitationes sive hæc et illa cogitatio modi sunt qui Dei naturam certo et determinato modo exprimunt (per corollarium propositionis 25 partis I). Competit ergo Deo (per definitionem 5 partis I) attributum cujus conceptum singulares omnes cogitationes involvunt, per quod etiam concipiuntur. Est igitur cogitatio unum ex infinitis Dei attributis quod Dei æternam et infinitam essentiam exprimit (vide definitionem 6 partis I) sive Deus est res cogitans. Q.E.D.
English (Elwes 1883)
Particular thoughts, or this and that thought, are modes which, in a certain conditioned manner, express the nature of God (Pt. i., Prop. xxv., Coroll.). God therefore possesses the attribute (Pt. i., Def. v.) of which the concept is involved in all particular thoughts, which latter are conceived thereby. Thought, therefore, is one of the infinite attributes of God, which express God's eternal and infinite essence (Pt. i., Def. vi.). In other words, God is a thinking thing. Q.E.D.
Modern English
Singular thoughts, this or that thought, are modes that express the nature of God in a certain and determinate way (E1P25C). God therefore possesses (E1D5) the attribute whose concept is involved in all singular thoughts and through which they are all conceived. Thought is thus one of the infinite attributes of God that expresses God's eternal and infinite essence (E1D6), or God is a thinking thing. Q.E.D.
