Demonstration — Part IV
Latin
Actio quæcunque eatenus dicitur mala quatenus ex eo oritur quod odio aut aliquo malo affectu affecti sumus (vide corollarium I propositionis 45 hujus). At nulla actio in se sola considerata bona aut mala est (ut in præfatione hujus ostendimus) sed una eademque actio jam bona jam mala est; ergo ad eandem actionem quæ jam mala est sive quæ ex aliquo malo affectu oritur, ratione duci possumus (per propositionem 19 hujus).

Modern English
An action is called bad only insofar as it arises from our being affected by hatred or some other bad affect (E4P45C1). No action, considered in itself alone, is good or bad (E4Pref) — one and the same action can be either. So we can be led by reason to the very same action that is now bad — that is, that arises from some bad affect (E4P19). Q.E.D.
