"Mais voudriez-vous bien réfléchir à cette question: Que vaudrait votre bien s'il n'y avait pas de mal?"

Simplified Meaning:

Imagine a world where there is no bad or wrong behavior. If everything and everyone were always good, we wouldn't really understand or appreciate what it means to be good. Goodness matters because it stands out against bad things. For example, we appreciate kind actions more when we've seen unkind ones because the contrast helps us recognize and value kindness. It's like if every day were sunny, we might not value the sunshine as much. But after a rainy day, we enjoy the sun more. Similarly, we only see the full value of good deeds when we know what bad ones look like. So, knowing about evil helps us understand and appreciate goodness more deeply. If everything were perfect, we wouldn't learn as much about being kind or making the world better. This idea helps us see that challenges and negative experiences can teach us important lessons and help us grow.
