E4P62D
Demonstration — Part IV
Latin
Quicquid mens ducente ratione concipit, id omne sub eadem æternitatis seu necessitatis specie concipit (per corollarium II propositionis 44 partis II) eademque certitudine afficitur (per propositionem 43 partis II et ejus scholium). Quare sive idea sit rei futuræ vel præteritæ sive præsentis, mens eadem necessitate rem concipit eademque certitudine afficitur et sive idea sit rei futuræ vel præteritæ sive præsentis, erit nihilominus æque vera (per propositionem 41 partis II) hoc est (per definitionem 4 partis II) habebit nihilominus semper easdem ideæ adæquatæ proprietates atque adeo quatenus mens ex rationis dictamine res concipit, eodem modo afficitur sive idea sit rei futuræ vel præteritæ sive præsentis. Q.E.D.
English (Elwes 1883)
Whatsoever the mind conceives under the guidance of reason, it conceives under the form of eternity or necessity (II. xliv. Coroll. ii.), and is therefore affected with the same certitude (II. xliii. and note). Wherefore, whether the thing be present, past, or future, the mind conceives it under the same necessity and is affected with the same certitude; and whether the idea be of something present, past, or future, it will in all cases be equally true (II. xli.); that is, it will always possess the same properties of an adequate idea (II. Def. iv.); therefore, in so far as the mind conceives things under the dictates of reason, it is affected in the same manner, whether the idea be of a thing future, past, or present. Q.E.D.
Modern English
Whatever the mind conceives under the guidance of reason, it conceives under the same aspect of eternity or necessity (E2P44C2), and is affected with the same certainty (E2P43). Therefore, whether the idea is of a future, past, or present thing, the mind conceives the thing with the same necessity and is affected with the same certainty. And whether the idea is of a future, past, or present thing, it will nevertheless be equally true (E2P41), that is, (E2D4), it will always have the same properties of an adequate idea. Therefore, insofar as the mind conceives things under the dictates of reason, it is affected in the same way whether the idea is of a future, past, or present thing. Q.E.D.
