Every living body continuously eliminates feces, it rejects what is not serviceable to the assimilating organism: what man despises, what arouses his disgust, what he calls evil, are excrements.
Human law cannot punish or forbid all evil, since while doing away with evils it would do away with many good things, which would hinder the advance of the common good.
Evil had to manifest itself and fulfill its role, so that ultimately Good could prevail. [...] Evil needs to manifest itself, for them to understand the value of Good.
The aphorism "Whatever is, is right," would be as final as it is lazy, did it not include the troublesome consequence that nothing that ever was, was wrong.
