E4P11D
Demonstration — Part IV
Latin
Quatenus rem aliquam necessariam esse imaginamur eatenus ejus existentiam affirmamus et contra rei existentiam negamus quatenus eandem non necessariam esse imaginamur (per scholium I propositionis 33 partis I) ac proinde (per propositionem 9 hujus) affectus erga rem necessariam cæteris paribus intensior est quam erga non necessariam. Q.E.D.
English (Elwes 1883)
In so far as we conceive a thing to be necessary, we, to that extent, affirm its existence; on the other hand we deny a thing's existence, in so far as we conceive it not to be necessary (I. xxxiii. note. i.); wherefore (IV. ix.) an emotion towards that which is necessary is, other conditions being equal, more intense than an emotion that which is non--necessary. Q.E.D.
Modern English
Insofar as we conceive something to be necessary, to that extent we affirm its existence; conversely, insofar as we conceive it not to be necessary, to that extent we deny its existence (E1P33S1). Therefore (E4P9) an affect toward something necessary is, all else being equal, more intense than an affect toward something non-necessary. Q.E.D.
