But without emotion there is no desire. It is desire that causes us to want peace. Without emotion there is no empathy. it is empathy that allows us to stop from hurting our fellow man or to understand where they are seeing things from. Without emotion we become robotic, able to rely only on instinct. there would be no reason to comunicate, no difference between us and the animals. I think you are missing the big picture entirely and only looking at some utopian outcome if man had no emotion or ignored them completely. there is a movie with Sandra Bullock and Sly Stalone where they are living in a future society where happy is the only emotion expressed. the outcome is NOT what one would hope it could be. Emotion and thumbs are what make us human.
Desire sparks emotion; desires can be dispensed with, for, desire has an inherent quality of selfishness. Our only need is patience towards realizing our god send needs. In order that we preserve peace at any cost patience shall prevail over desires. Patience is peace. Patience is anti emotion;neither peace is an emotion.
Animals only fulfil their just needs and live peacefully, unlike man who pursuits desires beyond his just needs.
