To Florus 1.80
Likewise, on the opposite side, when someone resolves to act wrongly to others' injury and becomes unjust or cruel, the act by which he harms others comes outward from the wickedness that an evil will sowed and generated within. But when the means are lacking by which the force of the hidden will may break out against one's neighbors, the character of kindness or malice is nevertheless complete in that will alone, when it has accomplished something good or evil not through a brief impulse but through deliberate thought and desire.
Latin
Sic et cum e diverso statuens prave agere in aliorum iniuriam, vel iniquus quis fuerit, vel crudelis; operatio qua nocet aliis, a nequitia foras proficiscitur, quam intus mala voluntas seminavit et genuit; cum vero deest facultas, per quam in proximos vis secretae voluntatis erumpat, in ipsa tamen sola voluntate, quae aliquid vel boni, vel mali, non impetu brevi, sed cogitatione appetituque patraverit, vel benignitatis est ratio impleta, vel malignitatis.
