Justice is the mistress and queen of all the virtues. - Cicero

Optime autem societas hominum conjunctioque servabitur, si, ut quisque erit conjunctissimus, ita in eum benignitatis plurimum conferetur. (...)

Homo, qui erranti comiter monstrat viam,
Quasi lumen de suo lumine accendat, facit
Nihilo minus ipsi lucet, cum illi accenderit.

Sed tamen ira procul absit, cum qua nihil recte fieri nec considerate potest.

for it is not having insufficient knowledge, but persisting a long time in insufficient knowledge that is shameful; since the one is assumed to be a disease common to all, but the other is assumed to be a flaw to an individual.
