In simple terms, this quote suggests that evil does not exist as a standalone entity with its own essence or characteristics. Instead, it emerges from and corrupts something that originally has value and substance, such as virtues or principles. Just like how an excess of salt can spoil food that was previously good, evil arises when there is an imbalance or distortion in what is inherently good.
The deeper meaning of this quote invites us to consider the nature of moral dilemmas and ethical choices. It implies that understanding and addressing evil requires looking at the underlying causes rather than focusing solely on the negative outcomes themselves. For example, if someone acts cruelly due to jealousy, examining why they feel jealous can help prevent future instances of cruelty. This perspective encourages a more nuanced view of human behavior, where complex moral issues are seen as deviations from positive qualities and intentions.
