As a personal discipline, we should refrain from moralistic judgments. This creates new perspectives. I love this quote: “Out beyond ideas of wrongdoing and right-doing, there is a field. I’ll meet you there.” – Rumi.
One other reason is that we are often wrong on our moralistic judgments, because we don’t know the circumstances that led to what we observe. It is so easy to be imprisoned in one’s frame of mind and not see that the situation is perfectly explainable in a moral way.
“One kind of life-alienating communication is the use of moralistic judgments that imply wrongness or badness on the part of people who don’t act in harmony with our values.” writes Marshall B. Rosenberg in ‘Nonviolent Communication: A Language of Life‘. Indeed jumping immediately to moralistic judgments can be deeply life alienating. Just avoid it.
